I'm working on a Subaru Impreza STI '99 Rally Group N.
The car has PRODRIVE ECU maped for GRAVEL and Fuel = ELF TURBO PLUS and inside EPROM by Prodrive ver. G2.32. The Eprom is 27C256.
I read the file inside and i'm trying to modify it.
Can you please help me with the maps, the FUEL, IGNITION, and BOOST map.
The WINOLS finds 1 map 12x9, looks like FUEL, but i think it is not correct. I think the boost is 12x12.

The problem with the car is that it has veri short rpm range max torque.
At 3000 rpm = 180 Nm
3500 rpm = 366 Nm
4000 rpm = 300 Nm
4500 rpm = 160 Nm
5000 rpm = 80 Nm

And that is very bad!

I'm sending the file and hope to help me!

Best Regards,

Its actually a G.E.M.S. bin, not Prodrive technically although they may have badged it as their own, thats what they do with Ecutek and call it PPP Prodrive performance Pack.

Have you tried using the G.E.M.S. software with it?

The Eprom is 27C256.

The Eprom has socket, and soft version Prodrive G2.32.

Tomorow i will take pictures and post on monday.

But can you tell me something about that file that i attached. Can i modify the turbo load on it?


Thanks for any help

Have you tried using the G.E.M.S. software with it?

I tried to open the bin file with the GEMS, but it does'n want to open bin files. I think that the eprom is only calibration file for the conection with the PC. I don't think that the EPROM contains any information on the engine control like maps etc.

There doesn't appear to be much table data in this rom image, but there is some. It appears to start at offsex 0x4200

I can see three distinct sections of the bin file.

4200h-6380h
6380h-6480h
6480h-6dc0h

It shows GEMS at the top, I think the best way is still the G.E.M.S. software and access the ecu directly with the openport 1.0.
