After a long hiatus Im back again with some mildly good news. I was never able to get a hold of that other ecu, but thanks to some sources I have managed to get the 256kb portion of the ECU that cant be obtained from the OBDII port. My next goal is to see what i can do with it. I have access to IDA ...

Hey all reviving an old thread, Ive managed to make contact with someone who has the exact same car however back in the day his car was flashed by a company called powertune. Im organising to grab the file off his car to compare it side by side to mine to see exactly what they changed, this should g...

Greetings All I have a few questions about some maps ive been finding while disassembling the bin from my car. I found what I first believed to be a 2d map that seems to be a 256x1 map with no headders or anything before or after as the decimal numbers start at 0 and rise linierly up to a set number...

unfortunately eurotech i cant help out with the Fiat xdf as im bogged down with both work and making my own xdf. If it helps i can tell you how im Making the xdf? Im using winols to find the map data in the hex by looking at it in decimal form to help out, then entering the address i find in a progr...

Attached is the .xdf im working on at the moment. Keep in mind its very raw as ive only just started it and im not sure what im doing. Need to find out how to enter checksum data into it so you can make changes in tunerpro instead of winols. Also @eurotech I changed the rev limit at the 2 addresses ...

thats what im doing atm, I was just wanting to make sure i was using the correct xdf parameters for the correct things.

e.g A Scalar for the rev limit,

a table for rpm scalar 16x1

it all seems to be working at the moment, slowly but surely

attempting to use TunerPro to make an .xdf file for the z18xe, Anywhere to find a decent tutorial on using Tunerpro to make an xdf? Happy to post my xdf progress however all it has is a MAF table, an RPM table which is used as a refference by other maps so it seems. and the soft and hard limiter as ...

That looks very similar to data i found on another forum however the info i found was from the Simtec 70 ecu and my car uses the simtec 71 This is what i found: RPM Limiter - C0E5 & C20C MAF Linearisation in kg/h - CBBA Spark 1 - D7F8 Spark 2 - E3FC Spark 3 - E4BC RPM Scale - C41A Airflow Scale ...

Thank you very very much :D I didnt realise tuner pro had its own hex editor in it and can view data in 3d tables too. Ill be playing around with it a bit more now i think. Unfortunately there arent any similarly defined bins out there for my car so it will make it very very hard to find anything. I...

Many thanks ill look into the Ostrich later when im home. As for loading the map etc it is a little hard to check as the loading process takes around 15mins to write to the ecu. I have solved the checksum issues as the car needs a new checksum whenever a change is made. What tools or programs do you...
