In windows calculator, switch to programmer mode. Then to Hex.

Enter in 808000 then minus the MUT address (eg 804e90) your interested in.

Eg:

808000-804e90 = 3170

In your dissassembly program search for Immediate Value (in IDA pro for example its the binoculars icon with the blue #).  Enter in 0xvalue – in above example 0x3170.

This will locate all examples of where this memory location was read or set.

If you’re wanting to log a memory address you can see in the code, but not in the MUT table, its the reverse:

Lets say its something like this (2 byte load memory address for CVT rcolt):

Locating 2b byte load on cvt rcolt

Using windows calculator again, hex mode :

0x808000 – 0x3164 = 0x804E9C

So the entry you’d want in the MUT table is 0x804E9C, place this where ever you think appropriate to log (you can pick any spot, just dont pick a MUT location you actually use when logging like RPM, throttle, load, knocksum .. then tell your logging program which MUT request to make to correspond with where you put it ).

In this instance its one byte of a two byte memory location for ecuload, so we’d want to write 0x804E9C and 0x804E9D into the MUT table.  I normally put both of these into MUT00 and MUT01.

If you’re looking for CZT Mut 2 byte load addresses – for 49100032 and 49100033 it’s 804d30 and 804d31

This is just a rough guide, don’t take my estimates that seriously just vague ball parks. All kW figures are at front wheels on roller dyno.

Stage 0

~90-95kW

Stage 0.5

95-100kW
K&N Panel Filter
Boost Pill out
Tune

Stage 1

110-124kW (depending on boost/risk profile)
K&N Panel Filter
3 port boost solenoid (grimspeed evo X unit is easiest)
Evo MR Metal Bov
Fuel Pump (walbro 255 or similar)
Tune

Stage 1.5

115-128kW (depending on boost/risk profile)
As above but cat back exhaust

Stage 2

130-140kW
As above but turbo back exhaust
Front mount intercooler (Todd Munkman kits fit awesome)

Stage 2+ extras:

kW as above but more likely on higher end – any of:
Injectors (WRX 440s or larger)
Exhaust manifold
Upgraded Wastegate Actuator

Stage 3

140-180kW depending on type of turbo
As above but
Alternate turbo
Easiest is stock frame turbo Like Kinugawa Hybrid turbo tf035-15t, full td04 in tf035 shell, or Blitz Turbo. Best outcome is probably not with stock frame turbo unless a fancy hybrid or Blitz

Stage 4

200kW and beyond (your budget sets the limit)
Much more serious mods – forged engine, head work, bigger turbo, aftermarket ecu, e85 & more

E85 on stages <4 add +10-20kW @ wheels

Boost vs EcuLoad

For colts, I’ve found 160 load to equate to around 13-15psi.  But most of us are running higher? How can we reliably tune the car when ECU Load stops reporting load past 14psi? The answer is 2 byte load.

Colt Ralliart 2 Byte Load

Evoscan (and Tactrix SD card) logging can handle something called 2 byte load but to do that some changes are needed to your MUT table, and also your logging configuration. Before we get into that, some more background.
ECU Load is only 1 byte load. To log it, only one MUT request is required.  It maxes out at 159.375.  2 Byte load requires two MUT requests, one after the other, to retrieve the ECU’s internal master load value, which peaks at 200 load.  The two requests for 2 byte load can cause some rare strange results but more on that later.  For the most part, it is reliable and enables you to log up to 17-19 psi.  This sounds good but how does this impact on tuning?

Impact of tuning with only 1 byte load

If you tune a Colt Ralliart with only 1 byte load, maxing out at 159.375, then your ignition maps at 160 load, will end up being tuned to what doesn’t cause knock at your maximum boost.  Peak power might be the same, but when your car is actually producing 160 load, its ignition will be set as though it was producing 200 load and be too retarded, resulting in less power at that point.  It’s tricky to explain but a few graphs might help:

ECU Load 1 Byte tuning session:

ECULoad Logging

Based on this, a tuner would look to reduce timing at 160 load, rpms 3500 through to 6000.  They should also reduce timing in 180-260 load range based on this data.  Lets check out the 2 byte load version of the same logging session:

ECU Load 2 Byte version of same tuning session:

Based on this, a tuner would look to reduce timing at 200 load, rpms 4000-6000 (note the reduced range to before).  As with above, other cells would be adjusted too.  The key take away is that the tuner using 160 load max would be seeing a very different picture of when the car was knocking to the tuner using 2 byte load.

The different picture would result in a different, and inferior tune.   Peak power would be the same, but power at less boost than peak would be compromised.

OK so it’s important – how do I log it?

You’ll need to do two things. First you’ll need to modify your MUT table and then flash the changed ROM to your car’s ECU.

Colt Ralliart 2 Byte Load For AUDM and most JDM rcolts:

Set MUT00 to 0x804E90 and MUT01 to 0x804E91:

Save the changes then flash this onto your car.  Now you need to modify your logging setup.  If you’re using Evoscan check the option :

Then when in Live Logging, ensure the Load dropdown is changed to Load MUT 2 Byte Load:

Tactrix SD Card loggers need to edit their logcfg.txt to include the following two lines:

paramname=Load2Byte1Raw
paramid=0x00
scalingrpn=x,256,*
isvisible=0

paramname=Load2Byte2Raw
paramid=0x01
isvisible=0

paramname=LoadMUT2Byte
scalingrpn=Load2Byte1Raw,Load2Byte2Raw,+,0.3125,*

So that’s Colt Ralliart 2 Byte Load. Give it a crack and let me know how it goes. Hopefully this helps you, or your tuner, get your rcolt tuned as best as it can be.

Oh one more thing – in the Evoscan log used above you might have noticed there’s a data point past 200 load – 240 load @ 5500rpms. What’s that about?

As the 2 byte method needs to make two memory requests, it is possible that in the time between the two requests that the memory location gets over written.  So we have half of 1 byte of information read, then both bytes are changed, then we read the 2nd byte.  The result is an erroneous ECU load result, that should be ignored.

Rewind a little, to when I first started tuning and adjusting my Ralliart Colt.  One thing I quickly learnt was that if you floored it in 1st, and did a fast high revving change into 2nd, there was a very real risk of over-rev, that then often resulted in a missed shift – grinding synchros etc.  After a while you get used to it and drive to get around it, but it never stopped being annoying and the risk never truly went away. Those that have blown a synchro know exactly what I mean.

How to make this throttle move faster? The traditional approach to a faster throttle with the Ralliart Colts or Colt Version R’s is to modify the throttle map.  However, I never found this made any significant difference to the speed the electronic throttle was being opened or closed.  Different but still not fast enough- if only we had a cable throttle!

Fast forward to the next Collingrove Hillclimb event. I was determined to have better control of boost and throttle.  I changed the throttle map, and also modified the Wastegate Duty Cycle (WGDC) maps to try and get more linear, controllable boost.  I was faster, but frustratingly, the car still really struggled in the tight twisty corners of the hillclimb.

Around this time, another rcolt.com forum member, AST, was experiencing a similar problem with his JDM import Colt Version R on E85 at the race track.

The following radical suggestion was made by member Rcus – try disconnecting the top clutch sensor and see if the problem persists.  So we both did..

It made an amazing difference to the speed of the throttle response.  At first, it felt too fast, if such a thing is possible. The over-rev on 1st to 2nd gear changes was completely gone.  Wheelspin was now easier to control with the right foot.  Amazing! It was like one of the biggest negatives of the rcolt was removed, and so easily.

So why’s it work? Imagine doing a hill start. You need the revs to rise as quickly as possible whilst you let go of the hand brake and slip the clutch.  The fastest throttle possible is needed in this situation.  OK – what about when driving in motion? Imagine driving in 1st or 2nd and hitting a bump. Your foot lurches forward and if it wasn’t for a slower throttle, your driving experience would be rather jerky and uncontrolled.  It’s this effect that I suspect had Mitsubishi apply a smoothing effect on any throttle movements.  Lets face it the average driver doesn’t need or want lightning throttle.  But for that hill start, all drivers need fast throttle!

So try it – disconnect the top clutch sensor and see what you think.  I’d advise logging the car after doing this though – as your car is more likely to find itself into throttle/load situations it didn’t find itself before. Also if you have a throttle controller already – don’t do this without removing the throttle controller first.

Note there are two sensors connected to the clutch pedal.  The side one detects whether the clutch is completely pressed in, and is used for the clutch in to start requirement (also frustrating).  The other sensor is at the top, and is easily disconnected.

Thanks to Rcus for suggesting this mod on rcolt.com, and if you try the Ralliart Colt Fast Throttle Mod, let me know how it goes!  If you’d like to see footage of my Collingrove Hillclimb runs, my fastest (to date) footage is here Youtube – Collingrove Hillclimb Ralliart Colt

Ralliart Colt Bad Flash Cant Idle Problem

• Flash goes as per normal – no errors are enountered
• When you go to start your Colt Turbo, it idles rough as, like the engines about to stall, it sounds very very sick. It just can’t idle normally.
• You’ll also have an engine check light (CEL) showing.

The first time it happened to me I turned it off, back on, and found the idle was still terrible. I then flashed it again, and again. Still no good.

The solution is to grab another ROM in your possession that is a fair bit different – either the stock ROM, or one that is a lot different to your current tune, and flash that back on.

Confirm your car can now start and idle properly. If it can, all good.

Now you should be able to proceed back to flashing the vehicle with the ROM you were originally intending to run.  There may be other methods but this is what I’ve done when it has happened to me.

If your Ralliart Colt has experienced this Bad Flash Cant Idle problem, let me know how you recovered from it, and whether this helped..

Assuming you have already done the pill out mod and have in your possession a Tactrix Openport2…   Your next option for more boost with stock 2 port is to adjust the two WGDC (Wastegate Duty Cycle) maps to be 100% in the 3 row area between 2500-3500, and one row at 6000:

By doing this, your wastegate will be closed longer and your Ralliart Colt will run more boost with stock 2 port boost control solenoid.  You might need to pull timing back a little to prevent knocking though, so it’s best to do this combined with logging either on Evoscan or via the Tactrix SD Card logging facility. I’ll write a guide on logging & another on ignition changes 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.  [these axis are actually incorrect, but that’s a subject of another blog post]

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

If you do this, but want more boost than this change gives – order a Grimmspeed 3 Port boost solenoid (Ralliart Colt needs the same one as for an Evo X)

Like everything on this site, do it at your own risk
