does my ecu look blown?

[92gsxbafaro]

i have a picture right here it was running the other day i turned it off for about a minute started it back up and it had no spark it showed no signs of that before.

after looking at the picture closer right in the middle there is something burnt and at the top left another thing burnt. now i dont know much about ecu's but i think that is my problem

The one labeled "IC106" controls the wastegate solenoid and fuel pressure solenoid. Your problem is either a faulty solenoid or a short in the wiring causing the excessive current.

If your isc was bad, you would have smoked the one labeled "IC107" or "IC105".

Found this !

Yes....

Found this !

what thread was that on?

Private forum sorry.

You could save your ECU after replace the bad driver from a donor ECU i think.
But you need to find the bad thing on the wiring or solenoid.

IC105 is blown but the ECU also has original capacitors and they have leaked. You can see the corrosion around C44 and R47.

Send the ECU to ECMTuning and get it fixed.

how exactly would i go about doing that wiring isnt really my specialty haha

Follow Steve's advice and send it to ECMTuning. They will fix anything that needs to be and retest it.

correct me if im wrong but you said ic106 was blown it looks like ic105 am i right.. thats the isc one right? would a bad isc cause that to blow because i dont want to get a new one put it in then have it blow again

If so, do this.

That's correct. If I remember correctly IC105 is the one that can also blow like that if C106 up front leaks and shorts the ISC trace that runs under it to it's 12v pad. However it sounds like you found a shorted ISC coil.

so if i replace the isc it should be good once i get a new ecu? i dont want to blow it right away again haha
