I have a 2010 Genesis Coupe 3.8 and have been able to read the ECU by using a Tactrix cable and PCMFlash software. Reads and writes work fine and checksums are corrected if a value is changed prior to writing. So far I've found the nuetral rev limiter and max rev limiter, and I believe I've found at least one set of timing tables. The rev limiters are 100% found, but I'm not positive about the timing table because I'm unsure how to find axis data. I'm using a demo version of wols to view data, and notepad++ to modify the data. I double check what I modified by opening the .bin in wols after making my changes. I haven't been able to find any reliable sources for map packs or definitions for this ECU. The end goal would be to define at least as much to be able to put a decent tune on the car by opening the .bin in ECUflash and making changes there. I have a paid copy of EvoScan that I datalog with through the Tactrix cable

I've attached the .bin and below are the addresses and values for the rev limiters. It's a Delphi MT86 ECU. Processor is Infineon TriCore 1766.

The stock hex value for the neutral rev limiter is 9C40 (40000 in dec). Delphi takes that value divided by 8 to give you 5000 for the limiter. This is at address 2BF24.

The stock hex value for the max rev limiter is D160 (53600 in dec). Delphi takes that value divided by 8 to give you 6700 for the max limiter. This address is at 2BF22.

Any help or pointers you folks can give I'd greatly appreciate!

I have the same vehicle and powertrain layout.

The Delphi ECU's no one ever bothered to crack making tuning them more or less a function of how much money you had for the few tuners that can tune them.

I'd be interested in helping define the bin file. Unfortunately time is something that's in short supply these days. Doubt anyone else would do it, so it's worth a shot.

This is likely going to be time consuming.

Thanks for taking the first step though!

I'm in the same boat with time contraints. Haven't made a lot of progress on this except for what's below -

Addresses 24434, 24528, and 2461C (17x7 maps) all seem to follow that same structure as the rev limiters: dividing their values plots a table that looks suspiciously like idle RPMs. I'm unsure of the axis descriptors on this one also, though. But here's a gentle bump in the right direction for some previously unknown info
