ok so i trader my turbo kit for a ls-v set up and he gave me a p28 ecu chipped with erickson racing rev 9500k, and i opend it up and saw this...does this mean its no good?






the back side..

 

looks like a bad soldier job which lead to a burnt board. try it... see what happens

 

i had a loose wire by my ecu and the same thing happened to me...it still runs fine give it a try and try to get your money back

 

this is my time to shine...

that is a circuit board... it is not supposed to look like that nuff said... other parts seem fried as well, stuff inside and on the circuits can be melted or destroyed... so reguardless of whether or not it works now, which looks doubtful,

It will not last as long as it should, and could be dangerous/not work as well too.

This is my time to steal your glory

That is Q31. It is the driver for the EVAP purge solenoid. The ECU will not purge your EVAP canister of fuel vapor. This happens when you connect engine sensors incorrectly, or have a short in the wire harness. I do recommend fixing it.

It also looks like a P28 conversion, not a true P28. What is the three digit code on the largest chip in the ECU (64 pin chip above the ROM chip)?

 

hmm...yeah looks kinda burnt to me. test it out first

 

I have a p28 ecu with a minor but similar damage it work fine for a week but now its idling at 2.5 and engage very rough. Does anyone have a ideas what can be wrong with it

 

good job on thread jacking a 6 yr old inactive thread...
