The 400 load blog posts on this site apply to the above XML too.  If you’re after a base file to start from, heres one with the 400 load patch applied, and the MUT table adjsuted to enable the required 2 byte load logging:

Note this is for the Manual JDM Rcolts only – do not flash this onto a CVT one (unless you’ve converted it to manual), or an AUDM Rcolt.

If you’re after the 400 load patch and XML for Australian Mitsubishi Colt Ralliarts, I’ve ported Antti’s work to AUDM, and added it into my extended XML for Aussie Rcolts. I’ll do a post/share that when I get time.

Apologies for the brievity, hope this helps & good luck!

The post JDM Z27AG Mitsubishi Colt Ralliart Version R 400 Load Patch XML appeared first on Turbo Colt.

The engine measures boost via a Mitsubishi concept of Ecuload, with a value between 0 – 200.  By default the Ecuload logging only goes up to 160, despite the ecu being able to see up to 200 ecuload.  How much boost is this? The following table is a rough guide (credit Merlin, Evo X tuning guide):

Boost vs EcuLoad

So the Rcolt Ecu can only see up to 200 load (about 17-18 psi depending on mods).  This means any map in the rcolt ecu that goes past 200 load will not be used by the ecu, instead it will use the 200 load column (fuel, ignition, mivec etc).  As ecuload is also a measure of the amount of air the engine is receiving, it also means as you go over the 200 load figure to say 220 load, the ecu is seeing and fuelling only to 200 load worth of air. This will cause the ecu to run leaner than the targeted AFR ration in the fuel maps, potentially catastrophically leaner depending on your boost level and richness of target AFR.

Another negative of the 200 ecuload limit is that the boost control system starts to not function properly as you approach and exceed 200 load. You might dangerously overboosting at 250 ecuload, but as the ecu only sees 200 load, it does not react to the overboost condition, potentially causing problems.

Fueling

With 400 load patch applied, the ECU will be more able to hit the target AFR ratio. A highly tuned Rcolt’s fuel map without 400 load patch might have a number of seemingly very rich AFR ratios in its fuel map like the example below:

With 400 load patch this over fueling compensation is not needed, and you can target closer to what you actually want to hit.  Example below:

Boost Control

With 400 load patch applied we can turn back on the factory ECU’s reactive boost. This is both a safety mechanism to stop over boost, but also a way to achieve faster spool when the ecu is not hitting the target boost you are wanting.

Turning on Reactive boost with 3 port boost solenoid

The following shows the configuration to set up reactive boost on a 3 port boost solenoid system:

WGDC and Boost Target Engine Load

The two WGDC tables define the wastegate duty cycle values for 1^st and 2^nd gear, and then 3^rd thru to 5^th gear.  With reactive boost, these tables set the initial wastegate duty cycle (WGDC). The ecu then compares the current ecuload figure against the equivalent Boost Target Engine Load table value (again 2 maps for the gears) plus the ‘Boost Offset’ value.

For example. We are in 2^nd gear, at 4,000 rpms and full throttle.  The WGDC map 1 (for 1^st and 2^nd gear) sets WGDC to 43.5%:

Lets say the car hits 160 ecuload.  The ecu then gets the corresponding value from Boost Target Engine Load #1:

In this case, 140.  It then adds this to the Boost offset value, to arrive at the final target load we are wanting to hit.  With a boost offset of 75, it means the ecu wants to hit 140 + 75 = 215 ecuload, much more than our current 160 ecuload.  The ecu will then modify the WGDC being used based on the reactive boost tables mentioned earlier (Reactive Solenoid Max Total upward WGDC correction tables etc).  So WGDC is increased, and the car’s boost & ecu load starts to raise. It continues to try and hit the target, adding (or subtracting) constantly during operation.  With this example we would see the car start to spool up faster than it would have otherwise.

The other benefit is over boost protection.  Lets say we are hitting 250 load, but the target ecu load + boost offset = 215.  WGDC would be reduced to try and rein in boost until it hit the target, providing a safety need. This safety net is particularly useful on the track, or on the dyno when a slower ramp up rate is being used.

Logging

To load an ecu with the 400 load patch you need to apply the MUT 2 Byte Ecuload patch.  This is done by changing the first two values in the MUT table to :

Then use your regular logging method (Tactrix or Evoscan, see turbocolt.com on how to set this up), with MUT 2 Byte Load logging enabled.

Other Random Notes

Launch Control

Example:

1^st & 2^nd Gear Throttle Limiter

Stock ecu limits throttle in 1^st and 2^nd gear, making 1^st gear easier to launch, but inhibiting 2^nd gear acceleration. This can be turned off by changing the table from stock settings to 100%:

Disabling Cat Warmup

The negative timing, and the leaner fuel serve to help the cat reach operating temperature faster. Set to 0, and 14.7 to achieve a smoother cold driving experience.

Disabling Immobiliser

Setting bit.03 to 0x0 disables the immobilizer check before starting:

Disabling 2^nd O2 Sensor

As above but set bit.01 to 0x0

Pops and Bangs

See turbocolt.com on how to set this up.  People want it, but its all a bit silly (and not as effective as modern pops and bangs or burble tunes).

Logging

See turbocolt.com for guide on Evoscan or Tactrix Logging. Also check out the bit about 200 load logging, to ensure you are capturing the newly patched 400 ecuload limit

Example Changes to Non 400 load tuned ROM:

Fuel Maps:

No longer need to target super rich AFR’s to try and compensate for ECU getting fueling wrong. Assuming injectors & MAF is dialed in nicely can set the fuel map to hit what you actually want to hit:

High Octane Fuel Map, before, unpatched:

After, patched:

Spark Maps:

Build up the ignition more progressively. Log knocksum and adjust ignition maps appropriately.

Tuned Hi Octane Spark Map 1, Mivec Max – map before:

Tuned map, after (note if tracking probably want to take more timing out):

Note – that is just an example, often timing ends up lower than this. To find the right timing, a combination of knocksum & traditional dyno tuning techniques should be combined. On boost, any regular repeatable knocksum value should be reduced to zero by decreasing timing until it does not occur anymore.

The above map will be used when MIVEC advance hits its maximum value.  The other hi octane maps are for MIVEC at minimum, or at target and should be adjusted similarly.

Comparing Changes in the Base to what you had before

Load up both srf files in Ecuflash, go file->compare Roms. This will highlight all maps with a change.

Summary of changes made – 400 load, timing map changes (log knocksum to see if safe), stationary launch enabled, cat warmup stuff removed (smoother cold driving), dual boost maps back on (wgdc 1 and 2), reactive boost back on (faster spool, overboost protection), more mivec (trial it maybe you like the old map), modified wastegate/boost maps for faster spool (will need tweaking, could be too much or too little – change both WGDC maps AND boost target load maps), Mut 2 byte load mod (enables proper ecuload logging).

Sounds like a bad idea? It probably is, but it its a neat party trick. As with everything on this site, do it at your own risk!!

Step 1 – Delay fuel cut

For the above method to work you need to delay how long it is before the ECU cuts fuel on throttle lift off.  To do this you will probably need to add the following new table into your Ralliart Colt’s XML:

Once added, you should be able to set this to something longer than stock, such as this:

Note the default is 500ms. If you have a value other than this after defining the table, it’s probably in a different location in your ROM and you’ll need someone to disassemble it to find it (leave a comment if you need help).

Step 2- Retard the Ignition

Now we want to run a lot of negative timing.  The example below produced quite a bit of pops and bangs and we ended up having to reduce the overall number of -15 degrees cells.  The car in question had a straight thru exhaust, which really helps these settings work.  On cars with catalytic converters, the settings below might not be as extreme:

Now the thing to focus on here is the pattern of -15’s. Don’t copy this ignition map, it probably wont suit your car.  The idea is to set a similar region of -15’s in all your ignition maps, at light throttle, and above a certain rev range.  The lower the revs and the greater the throttle range you do it for, the more it will do it.

Step 3 – Add more fuel

In the same or similar areas of the map that you set -15’s for in the ignition maps, we want to run more fuel than normal.  Set 10’s where you want to encourage pops.  Here’s an example but note this one doesn’t exactly match the ignition map changes – I was concerned about washing the bores in petrol unnecessarily so went a little tentative:

Step 4 – Flash and Revise

Flash it on and test it out. It won’t give your Ralliart Colt  pops and bangs all the time, but it will make it a lot more likely.  To test it out play with lifting off throttle, when your car hits the -15 & 10:1 cells you set.  In this example, to test I would accelerate in 2nd or 3rd, then back off leaving revs 3500 or above.  Then back on & off throttle again. It should be enough to make it happen.  Best results are experienced when doing a hills run when you’re on/off throttle a lot, and at higher revs than just cruising.

Let me know if you find a more effective way to do it in the comments! Thanks.

I’ve made an XML stub file to help in the process, but it’s not essential.   If you’re looking for the complete XML for the JDM models I might be able to help (leave a comment below and I’ll email you).

Anyway back to downloading your ECU rom image.  Here goes:

Install EcuFlash from this link

https://www.dropbox.com/s/u55hat1zck70krz/ecuflash_1444247_win_beta.exe?dl=0

I’ve had reports that the later versions of ECUFlash have some issues reading and writing, so until I’ve investigated these myself I recommend running this older version.

Put the XML in

Go to C:\Program Files (x86)\OpenECU\EcuFlash\rommetadata\mitsubishi folder

Make directory called ‘Ralliart Colt Turbo’

Download these two xml files and put it in this new folder

https://www.dropbox.com/s/7k5nw3ywjnnfwsf/38350016%20JDM%20MT%20Andy.xml?dl=0
https://www.dropbox.com/s/nudulw5nrts9jes/Coltbase.xml?dl=0

Connect to your ECU

Connect the tactrix to your computer via USB.

Run EcuFlash

In the Menu to ECU->Select Vehicle Type. Make sure its set to Colt (768k) 2006+ mitsubootloader M32176F6. There should only be one Colt (768k) entry.

Now you should be ready to read your ROM!

**

In the car, boot up your laptop. Connect Tactrix to laptop. Now connect to OBDII port of your car.

Now with everything connected up you should be able to go menu ECU-> Read from ECU

Software will display an information box asking you to turn on your ignition. Do so, and then click ok. You want ignition on, not just accessories.

It should now be reading your rom. If not? Remove tactrix from OBDII port and reconnect it. Try again. If still not working, unplug it from the computer and the car, then plug back into the computer, then the car, and try again. Still not working? Try wobbling it in the OBDII port to put it at a small angle (just to see if that improves the contacts). Still not working? Houston we have a problem.

Assuming no problem, and the ROM was downloaded?!

Go Menu File – Save ROM As, change the file type to .BIN, call it something, and done.

EPIC WINS.  You have now completed your Z27AG JDM Colt Version R ECU Download.

So, you’ve heard about the free Macca community flash available on www.rcolt.com and want a piece of the action.  First off, we need a huge disclaimer!

Warnings: Make sure you feel comfortable with the ECUFLash software, copying values etc before doing it for real. If you’re terrible on computers, you probably shouldn’t be doing this without help of someone who is. Make sure you do everything carefully be slow and methodical. Last thing you want is a bricked or broken rcolt. When you’re reading an unflashed colt for the first time, make sure all your Open ROMs are closed FIRST. If all ROMS are closed you can’t upload one and brick your car. I bricked a mate’s car, and let me tell you it’s a horrible feeling. Check, and re-check immobiliser code copying & save worked, as with WGDC maps.  If you do happen to write out the wrong immobiliser code? You’ll need to permanently disable the immobilser.  I have written up how to do this at the end of this guide. Make sure you’re laptop isn’t likely to crash mid-writing or run out of power.

Final warning is to avoid the latest version of ECUFlash, I’ve had a few people say it bricked their ECU until they downgraded ECUFlash, and reflashed it. So until this has been confirmed, use the version I link to further down this page.

If unsure of something, as the community.  Read and re-read macca’s info.txt. Read the forums. If you do all this, the whole flash process should be easy and trouble free.

Ralliart Colt ECU Flash Guide

Buying the Tactrix OpenPort2

Go to www.tactrix.com and buy yourself an ‘Openport 2.0’, with delivery, in AUD you’re looking about around $250 depending on exchange rate.  The Pin out cable is no longer required as discovered by Sliders7 on rcolt.com (awesome thanks brother).  So there’s no need to order any cable with it, just the base Openport package with its included USB cable suffices.

Plug your tactrix device into the computer via the supplied usb cable. Load ECUFlash.  It will automatically start to flash the tactrix device’s firmware. I think this is how it gets around not needing the pin-out cable.

Using ECUFlash – Immobiliser & WGDC1/2

Once the update has been done, let’s start digging around in ECUFlash.  Note this section isn’t how to flash your car, just teaching you how to use ECUFlash, preparing you for the real deal further down. Go File->Open ROM, find the Stock Rom.bin file from Maccas Zip.  Ok let’s check out where the immobiliser code sits. Tick the checkbox as in this screenshot and the immobiser code comes up:

With ECUFlash you can load multiple ROMs and compare. So let’s compare this stock one with the stage1 3port. Find that rom and open it. Once open, you’ll have two ROMS open like below. Go to ECU->Immobiliser and tick it like before.  Screen will now look like this:

This is how you compare the immobiliser codes (or any of the settings) between ROMS. Note- the value in here is hexadecimal. Don’t think you can just type in your stereo pin code!  If we were comparing our downloaded vehicle rom, we’d click in our car’s rom immobiliser code area, and then select Edit->Copy. Then go to the code area belonging to the ‘to-be-loaded’ rom (in this picture where it says A90B) then go Edit->Paste.  So that’s how you change immobiliser code.

Next bit to learn about is the WGDC 1 and 2 maps.  For each of the roms open, tick the Turbo->WGDC #1 and #2.  You’ll get something like this – move the windows around so you can see them all clearly.

The two 3-port maps are on the left, and the stock boost maps are on the right.  You can see the stock solenoid is running pretty much 100% capacity, vs the 3 port version that holds between 50 & 70%. This is because Macca’s 3port tune lowers the wastegate duty cycle as the grimmspeed 3 port supports much higher possible boost levels – so to prevent overboost and engine failure he has scaled back from stock.

So assuming you’re running only 2 port- we would need to copy the stock maps over the top of the 3-port’s ones, else we’ll have a lot less boost!

Let’s do it (unless you DO have a 3 port, in which case leave Macca’s WGDC maps as they are). You need to copy all values for each map. You do this by clicking Click into any cell of the map you want to copy, then going Edit->Select All, then Edit->Copy. Then go to the map you want to overwrite, click in the first cell (500,10), then select Edit->Paste.  Done. Repeat this process for the second map.

Once you’ve moved the stock maps onto the stage 1 3 port maps, you they should look like this:

Now select your stage1 3port rom file, and save it to something like ‘Good 2 port Stage 1 flash.bin’. So now you’ve seen how to copy paste values, have a look around the settings, check rev limit and MIVEC maps. I didn’t change anything here – kept the lower rev limit of the macca flash.

It’s important you’re comfortable with ECUFlash before you get anywhere near your car.

Doing the Flash

When you’re ready to actually flash your car, connect tactrix to ODB2 port (see https://www.youtube.com/watch?v=KdY1ZJKRQE8).

With ECUFlash open, and tactrix connected to your laptop, use the Menu to close any of the currently open ROMS (ie File -> Close ROM). Do this until all open ROMS are closed. This will ensure you don’t upload before you’re ready. Now select ECU->‘Read from ECU’. This will download your car’s factory ECU

NOOBS – DON’T BRICK A MATE!

• Make sure you CLOSE ALL OPEN ROMS FIRST
• <- AVOID THESE BUTTONS, use the menu.
• Go slow and methodical. Check and triple check

ECUFlash will then ask you to put your car in ignition mode (not running). For some reason, it took a few goes for me to get this one working.  I don’t know why. Eventually I got it working by trying with the car running. Freaked me out as when it started reading the ECU, the engine cut out. Heart stopping, but turned out fine.  Another car I’ve flashed, it worked first time with ignition on so I don’t know what happened with mine needing it running.  Sometimes the tactrix device just needs a bit of a wobble around before it wants to work.

Once you have downloaded your rom (it takes a few minutes), save it.  Do not lose this file. Macca recommends saving it everywhere to make sure you never lose it.

Now you need to copy across the immobiliser code (as per our playing around above, but from your just downloaded rom), to the ‘Good 2 port Stage 1 flash.bin’.   Once done, save the 2 port rom again. Now you’re ready to upload.  Double check you have the right immobiliser code saved. Check your factory rom, along side the new Good 2 port Stage 1 flash you just made.

When ready, use the menu ECU->‘Write to ECU’ and away it goes just like in the youtube video.  Once finished, turn off ignition, turn it back on, and attempt to start!

Good luck!

Other Bits & Bobs

ECU->Select Vehicle Type

If you need to, this is what the setting should be for ‘Select Vehicle Type’:

Help! Uploaded wrong Immobiliser Code!

Don’t panic, you can get the car running again.  You’ll need to disable the immobiliser though.  With the ROM you want uploaded, go to ECU Options #2. The screenshot below shows a rom with immobilser enabled (top), and then disabled (bottom):

To Bit.03 to zero, click into one of the values that is already a ‘0’.  Then go Edit->Copy. Then select the Bit.03 value, and go Edit->Paste.  It should now look like a ‘0’.  Compare against another rom to ensure you got it right and didn’t change any other fields.

Then upload to your car, and it’ll be unbricked.  No immobiliser though. How much of a problem is that? Probably not much – as long as you keep it quiet! Modern cars have had immobilisers for many years now, so the chances of someone trying to hotwire your 2006+ colt is pretty damn slim.

Still concerned?

Apparently, you can find your immobiliser code by locating the immobiliser module that is deep in the middle of your dash somewhere.

I haven’t verified this yet, but once I do, I’ll write up how to do it.

MOAR BOOST –3 PORT?

This guide is aimed at those flashing their 2 port rcolt with the macca tune. So we swap out the 3 port WGDC maps in the base macca tune, for the stock 2 port ones.  IF you already have a 3 port-  then there’s no need to do this. You just need to set your immobilser code, and flash it.

MOAR BOOST – BUT NO 3 PORT?

But no 3port? Change the stock WGDC maps to be 100% in the 3 row area between 2500-3500, and one row at 6000:

If you increase the boost in these ranges, you might need to pull timing back a little to prevent knocking. I’ll write a guide on doing this at some point.

There are some maps out there that have lower duty cycles in 25% and 30% TPS range like the stock map, I’m presuming this is to reduce chance of pinging.

Another change I’ve seen is changing the 6500-7000 range, to a slightly higher, but still under 100% setting.  Macca files rev limit is 6499 so changes above 6500 won’t work unless you also lift rev limit.

Like this entire Ralliart Colt ECU Flash Guide, do it at your own risk!
