Graphing Knocksum with Evoscan

September 22, 2015 // 0 Comments

Reading the Tactrix SD card CSV logs in excel is doable, but sometimes you need a quick overview of how the run went, or perhaps you might want to send screenshot of the log’s knocksum to another enthusiast. The best way to do this that I’ve found is to graph knocksum with Evoscan. This is how you do it: 1. Buy Evoscan from here.  They’re a small company, so go on do the right thing and pay the small fee 2. Download & Install it 3. Load it. You should see the following screen. Click the Graph / Logs button: 4. This will load the graphing screen (below). Note you can also do live logging from this screen. Anyway, lets set it up to read your Tactrix CSV log. Set Data Values to Maximum Set Load to ECULoad.  If you [...]

Ralliart Colt More Boost with Stock 2 Port

September 22, 2015 // 0 Comments

WANT MORE BOOST – BUT NO 3 PORT? 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 [...]

Tactrix OBDII Logging

September 21, 2015 // 4 Comments

Did you know you can track your turbo Colt’s performance and diagnostics via Tactrix OBDII logging? Things needed: Tactrix Openport 2.0 Micro SD card (must be formatted to FAT32!) logcfg.txt file Download my sample logcfg.txt from here (right click, Save As), then copy it to your Micro SD card. That’s pretty much it!  If done correctly your Tactrix device will now log to CSV files on the Micro SD card.  These can then be checked out in a spreadsheet program, or via Evoscan. More advanced users may want to edit which MUT requests are being logged, you can do this by editing the logcfg.txt file with a text editor like notepad.   Also, note that not all of the MUT requests in this logcfg.txt will be correct. They key ones [...]

Ralliart Colt Lost Immobiliser Code

September 21, 2015 // 0 Comments

Help! I’ve just flashed over my Ralliart Colt’s Immobiliser Code! If you’ve accidently flashed over the top of your rcolt’s ECU, don’t panic, you can get your Ralliart Colt running again.  You’ll need to disable the immobiliser though.  Load ECUFlash and the 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 change Bit.03 to zero, click into one of the values that is already a ‘0’.  Then go Edit->Copy (or ctrl-c). Then select the Bit.03 value, and go Edit->Paste (or ctrl-v).  It should now look like a ‘0’.  Compare against another rom to ensure you got it right and didn’t change any other [...]

Ralliart Colt ECU Flash Guide for Noobs

September 18, 2015 // 4 Comments

Formally known as the Ralliart Colt Noob Flash Guide.  This relates to the AUDM Ralliart Colt, though if you have the XML for your turbo colt, some of this might be useful.. 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 [...]

Australian Ralliart Colt Turbo

September 18, 2015 // 2 Comments

  The Australian version of the Ralliart Colt turbo was released for sale in August, 2006 and was sold through to late 2011. Unlike many other budget hot hatches featuring only body kit & a set of mags, this pocket rocket was the real deal.  It had the obligatory body kit (featuring some aggressive wheel flares and an evo-style bonnet vent!), a MIVEC twin cam intercooled turbo 1.5, Ralliart tuned suspension, bigger brakes and a beautiful set of recaros borrowed from its elder brother the Evo 8 MR. This is a good list, but there are a few other things that set the Ralliart Colt Turbo apart from the dressed-up hot hatches in its segment.  Starting with the bare chassis, they were separated out from the regular Colt [...]
