Alright, so I got evoscan and ecuflash. My only problem is people keep talking about these 02 definition files I need to load. I have NOTHING like that. I plug in the cable, open up ECUflash and tell it to read computer. It asks what car I have (evo 6-7, evo 8-9, eclipse, wrx, sti etc.) NO regular lancer. I tried the 01-05 evo 6/7 but that didn't work. I can't get anything to come up to get any maps or values or anything.

 

Use the Evo 8/9 option. All these choices pertain to is how EcuFlash will talk to the ECU. Its basically the communication commands that it expects to receive and what it will send back in return in order to be able to read the data. If you pick the incorrect option it simply won't be able to read your ECU. The definition files are used for interpreting the data that EcuFlash reads from your ECU. Without a correct definition file, the ROM data will just look like random values. The definition file arranges the data in a readable fashion.

 

im in the same boat as you... i bought the cable , and downloaded ecuflash but when i use ecuflash i have a similar problem its connects and downloads the ecu but then i get a message saying something along the lines of no definition file, ive tried saving the file but when i try to reopen the file it says that its corrupt , and there is no fields that you can change because it doesnt detect it at all. ive tried my cable on my 02 lancer es 5 speed and i also tried it on my brother 03 lancer oz 5 speed. ive also tried the 03 def file for the oz that didnt help...

 

There are many different definition files for each year and transmission. Send me a copy of your ROM in a .hex file and I'll see if I have a working definition file for you. If not, I'll make one.

 

how do you make your own definition files

is there a step by step for this??

 

is there any way someone can help me I’ve got my turbo set up on and now trying to use ecu flash yo flash a bin/tune onto my ecu but when trying to connect to my ecu it says failed to connect and when trying to load the bin onto ecuflash it tells me to select car and there’s no option for my 05 4g94 I have a cm5a lancer gsr 4g93t bin file but I don’t know if this is the correct one I need for my plastic case ecu, please any help would be great
