LT1 pcm won't flash anymore.

[babywag]

Vpp voltage is used to erase the chip and is applied internaly on the board via software switch. EEhack send a special command to pcm to do it and if the response is not as expected it might give an error. I think I got this error once or twice but can`t remember anything about it. Can you make a verbose log.
The vpp voltage must be solid 12v for the chip to get errased.

I'll try. I put in spare pcm and it flashed fine. I'll try to duplicate error on the bench w/ one that refused to flash.
I have a feeling the flash chip(s) are possibly the cause?

They are good for 100 000 erase/program cycles, according to Intel specs.

You can try reading the pcm also. If it reads fine, check the bin for corruption.

lets see a verbose log, so we can see the ECM's response when it tries to enable VPP
