Ok, i know i"m starting to sound like a broken record.

Did Mitsubishi make several different model numbers for their ECUs for Eclipse GST/Xs?

I bought an ECU from a guy for told me he had a 1997 Eclipse GST 5 Speed. (2nd ECU bought). The 1st ECU and my Orginal ECU have the same number on the Side 5287, E2T61687. Though on the one i bought most recently, the numbers don't match up. The side says 1911 or something like that (don't have the ECU next to me at the moment) Plugged the newest into my car and the car wouldn't start up. Would just continue to turn over. I checked into it and Its not an EProm, so i'm all confused. Could they guy be lieing to me and its actually from a Automatic, or a N\A Eclipse? Does anyone know where I can find model numbers for ECUs? I've been searching and can't find a site that tells me.

Thanks

 

thats not good.. I cant answer that but ill look.

Did you check your guage wires like i told you. I think you messed something up when installing the guages and that caused the enitre problem. Honestly an ECU is hard to break it is not often you hurt one

 

sorry i forgot to answer you on that. Yes I did check my wiring dismantled everything and nothing changed.

i had a bad feeling about the new ECU too

 

ya dont use the mis matched one.... We cant find any numbers for ya yet though.

 

ya i'm still looking myself. There's a company over in Florida that sells ECUs i'm going to call them and get one from them. they're expensive (300bucks) but its worth getting the car fixed. I'm going to tell them every single number on my original ECU. lol.

 

thanks for looking

 

ok i dont know if this helps at all but at least this shows the sticker you should be looking for and it gives a list of valid ECU's for 2g turbos
