JAlfa  Remapping my Alfa Romeo MiTO with KESS
Dear Car enthusiasts,

I have purchased a KESS V5.017 clone from AliExpress (yet to arrive). I have already installed KSuite, WinOLS, ECM and some other programs. My goal is to remap my Alfa Romeo MiTO 1.3 JTDM Eco (Marelli ECU) and to learn as much from it as possible. 

When the KESS clone arrives, I want to connect it with OBDII and read the current ECU, and write a modified one. I have downloaded the 850GB WinOLS Damos database. In that database the two(!) attached Stage1 files were present. These are meant for the Alfa Romeo MiTO 85HP. Can they be used on a 84HP MiTO? I now I can only use a Stage1 file that originates from the same ECU version as mine. Since I do not yet have the KESS device, I have to wait until I know which exact ECU sw/hw revision I have

With the use of WinOLS I cannot seem to understand what has been changed comparing it to the original ECU dump. 

Could you please show me / teach me how to see what changes have been made to this Stage1 file? I know how to use a hex-editor, I have highlighted the differences between the two files. However, the results are incomprehensive for me. 

Thanks!!

Information:
Alfa Romeo MiTO 1.3 16v JTDM ECO Start&Stop
84 HP
Marelli MJ8DF

If you have the correct damos for your ECU software them connect an original to modified then you can view differences in winols, even ECM will show differences.

RE: Remapping my Alfa Romeo MiTO with KESS
Thanks, I understand and already tried. However, how can I verify that the changes made in the STAGE1 file are only resulting in more HP and Nm?

For example, what if the STAGE1 file has other alterations, such as EGR off, or S&S off? How could I check that?

RE: Remapping my Alfa Romeo MiTO with KESS
Youll have to find where EGR maps are located like switches and hysteresis maps, some searching should help you, stage 1 maps usual go to the same limit of your turbo but sometimes injectors etc

So a tuned map will have more torque request (drivers wish) more boost, more injection and sometimes start of injection but not always for a small boost in power 

Also you'll be able to tell that EGR maps are smaller than most useful tuning maps like the above

RE: Remapping my Alfa Romeo MiTO with KESS
Thanks for the clear explanation! smile And would you perhaps be able to tell me whether or not remapping my MiTO (Marelli MJ8DF) is possible with KESS ? My research told me it should be possible. However I am in doubt.

Not 100% sure on marelli but I'm sure somebody else will be able to tell you

Good luck
