Another 1G Ecu question...

[my_gst95]

I have a AWD 1992 Federal 5speed DSM. I recently bought an eprom 92 ECU off ebay, but it's for a FWD 1992 Federal AUTO DSM (MD165529). Is the only difference the injector code? Any difference in the 5speed vs AUTO code? I have a chip programmer so I just want to make sure I'm not skipping anything that needs to be changed.

Just burn a new EPROM with the E931 code. I haven't looked closely at the E932 ATX code to see all of what's different but I have put the E931 code in a few ECUs that started life setup as automatics. Beside the Park/Neutral input the ECU and trans don't communicate they share inputs from the TPS and VSS.

Thanks, Steve. I don't know W-T-F I was thinking since it's an EPROM chip anyway, I'd be burning the standard E391 DSM-ECU group provides with the correct fuel maps and injector sizes (which would have been changed anyway). I guess I just wasn't sure on the automatic tcm communication with this ecu. Thanks for the clarification

So if one intends to go with DSMLink... does it matter if the ECU that is being used is from a 1990 FWD and I want it for a 1990 AWD?

No.

So If I just plug the FWD ECU in my AWD it will run properlly?

Close enough, even without the DSMLink.
