That's not the purpose. KEN wanted to know if the injector circuitry was the same as the LMM. You can't flash the operating system between the 2 so he wasn't sure. I didn't pay that much, I expected it was fubared any way as I told the seller it would be. I just wanted it for our experiment. There is another company trying to sell cores for $300 and there sold as is with an internal rattle. I paid around 65 to my door. If it advances this project for all of us, it was money well spent... if not, I can not eat lunch for a few days to recoupe what I wasted....
Plus none of us wanted to sacrifice an 800-1000 known good one for this.
Might have been a solder issue at the board level. The caps look intact
Also I got a communication code this morning on my LLY FICM. Was pending but now I am concerned... I cleared it and it hasn't come back. Could have something to do with the remote start. It has a 15 second delay to allow the glow plugs to warm up. Might need to have it shortened.
Sorry 'bout that, my sarcasm didnt come thru the keyboard that time.
I thought it was damn funny myself when first I saw those pictures.. It's Toast...
But the more I look at that area on my LMM board, there isn't much to get smoked on top or bottom. Might just be charbroil on the surface. But these look to be 4 layer minimum. No light gets thru, so probably something critical traces thru that zone we can't see. But my goal for that crispy critter is to just compare the chips, and read the mem to better understand why we can't write an E35A OS onto a E35B board. There is a Bosch and GM # designation difference that I recall posting about a couple dozen pages back. But on the surface, they look identical, and I've yet to source matching schematic for either.
As for our FUCM upgrades, think we can all see what parts of the early Bosch driver circuit really needs some attention. There lye 7 years of Bosch CDI technology behind those crispy caps. Going with Lead Free solder in EU back then? Seeing a trend here.. Whatever the cause, we need to go crazy overkill on the High Voltage PCB attachment points. It's obviously a Time related failure, and I'd prefer these new boards outlast me...
I am curious if it has a Tune on it or if it's a stock file. Seeing as how there is a few of these cores out there, I am curious if it's a manufacturing component issue or if it's something caused through tuning.
I know on the Gas side when people tried to manipulate the Drive by wire TB tables to make it more responsive it would cook the LS1 Style ECU's EFI Live had to make it RED and put a warning that they would cook the ECU if they modified the tables.
