Pretty sure I cooked the ECM - TunerCats
connected, downloaded the ECM just fine.
saved the download so I had a current 'stock' copy.
opened new calibration file.
chose program ECM, saw it Erasing Flash, then this error. (see attached)
now when I cycle power, the fans come on and stay on until I turn the key off...
So, someone tell me I've cooked it so I can start hunting for a new one... OR if there is a slight possibility I can resurrect this... please please please tell me.

Re: Pretty sure I cooked the ECM - TunerCats
I am not very familiar with programming the pcm. I have done this a total of TWO times only just to see how it was done. So I can't really offer expert help.
That being said, I would download WinFlash (if that is not what your are using already) and see if it can read the pcm.
TunerCat
As far as I know, if the pcm is "bricked", there are only two options: 1) Buy another pcm or 2) get someone to "unbrick it" by replacing the soldered-in memory chips inside. Either way is probably at least $100. And no, I don't know who to recommend.

Re: Pretty sure I cooked the ECM - TunerCats
If you are good with electronics repair this may be of interest.
How to fix the PCM Flash Memory
LT1 ECM 16188051 repair source?
As I understand it, you would need
1) the programmer ( a TL866A at $50 should work)
2) two memory chips and sockets (about $10) , and
3) some fine-pitch soldering and un-soldering skills.

Re: Pretty sure I cooked the ECM - TunerCats
Thank you both.
I've went ahead an bought I new PCM from another member that already has the sockets installed... I'm now looking for more chips in the event I do this once again.
Thank you both for the assistance... I guess another week of waiting to hear what this sounds like is what is required...
