ECU fried, can I salvage my DSM Chips?

[jonezj]

I recently did a lot of fuel mods that were a bit outside of my AFC's tuning range, so I had a DSM chips burned for me and bought a remanufactured, socketed ECU. Then the ISC died and apparently took my new ECU with it. So, I replaced the ISC motor and put back in the old ECU just to get it drivable. Well, the old ECU works, but obviously its all kinds of rich because the AFC is zeroed and the injectors are 680cc and increased fuel pressure to 43. If I put the "new" socketed ecu in the car won't turn fire up.

My question is, what is the probability that the DSM chips is fried? Can I take it off of that ECU and buy a new socketed board and expect it to work? Or do I need to get a new DSM Chips ordered as well. I am not home to crack the case and try to assess the damage to the ECU personally. Any help is appreciated. Thanks!

Additionally, anyone know a good place to get a presocketed EPROM ECU for a 92 AWD? =) Thanks

Blowing the ISC drivers doesn't usually kill the ECU. It can kill all the solenoids and fuel pump and make the car seem like the ECU is dead. So depending on what really happened the ECU might be repairable and your chip might be fine. If it's not, and you the original purchaser, Jeff will replace it for a minor fee.

Thanks Steve,

I'm pretty sure that my fuel pump is fine, because as soon as I swap in the old ECU, the car runs, not beautifully due to the inaccurate tune, but drivable. I'll have the solenoids checked out to be sure, I'll get ahold of Jeff to try and get a new ECU soon. Thanks again.

Sorry, I wasn't suggesting that it damage the fuel pump or solenoids but that the damage could disable the rest of the drivers and disable the pump and other solenoids so that the car wouldn't start.

What I was suggesting is that you have the ECU checked to see how badly damaged it is before replacing it.

steve would be the man to send your ECU to, he can most likely repair it.
