OBD-II ECU Reflashing - Specifically related to Mitsubishi Evo

[itistime]

Hello all,

I have been trying to figure out the exact procedure for remapping the stock fuel/ignition map on the Mitsubishi Evo, I figured that I can tinker with it myself rather than keep paying alot everytime a part is added and a recalibration is necessary.

Rather, I have found that the Evo 8 specifically, uses a passthru device to download the map, I believe, the device is readily available.

However, this is where things become hazy. I believe the maps are downloaded as pure hex, and some sort of software is needed to translate the maps in order to provide a clue as to their meaning.

If someone could shed some light on this, I would much appreciate it.

Thank you in advance

Hi,

If you have not been into assembly and HEX programming sort of thing, you might find it difficult, however WinOls software can help u a lot. But locating the maps is a bit tricky in a 512K or 1MB Hex code. More importantly, changing them needs a deep understanding of how things work and how to change their performance by changing the maps.

I don't want to disappoint you, but if you don't have enough instruments and devices to do the job done, pay the guys who have a Dyno and Experience and I promiss you'll save money.

The only thing is that if you want to get into this business and then story changes and you can buy the required equipments and go for the knowledge.

However, I'm not sure if there is an IZY PIZY ready made solution to do that for EVO.

If you still insist, I would recommend you a stand-alone ECU rather than re-mapping your own ECU. An interface comes with your Stand Alone ECU, that connects it to your laptop and you can see everything visually and change it on the fly, without being worried of checksum, protocol mismatching,.... . That's something the guy in "Need ofr Speed"has on his car and changes everything on the fly For having that, you're supposed to spend 3-4K USD which is much better than going to find how to change the manufacturer ECU.


Cheers
