Mitsubishi Colt Ralliart 400 Load Patch – AUDM JDM Rcolt Z27AG

May 25, 2022 // 0 Comments

400 Load Patch for Mitsubishi Colt Turbo – Why we need it 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 [...]

Ralliart Colt Z27AG Pops and Bangs

May 7, 2018 // 0 Comments

Merlin’s Guide to Tuning Evo’s talks about one way to get Pops and Bangs from your Mitsubishi Evolution. A while back I tried applying it to Turbo Colts, namely Australian delivered 2006 Ralliart Colts. The method basically involves richening up the fuel and retarding the ignition in certain spots in the map. When you lift off throttle, timing goes negative, and fuel is dumped in, so that we get lots of fuel getting ignited very late, and hopefully causing this to continue igniting outside of the engine. 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 [...]

Z27AG JDM Colt Version R ECU Download

December 24, 2015 // 5 Comments

Assuming you have got yourself a Tactrix Openport, the following steps detail how to do the Z27AG JDM Colt Version R ECU download. The Japanese Colt Version R’s use a different ECU image to the Australian Ralliart Colts so the Aussie XML won’t work on the Version R’s. 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 [...]

Ralliart Colt ECU Flash Guide for Noobs

September 18, 2015 // 5 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 [...]
