YAY! Fixed a bricked pcm this morning...

[babywag]

0411 cal-flash failed, not sure why, have never had it happen before. Zero communication, unable to detect the controller.
It was like it wasn't even powered on.
Bought myself a new programmer and adapter.



Removed the flash chip, read it and it was nowhere even close to a valid .bin
Reflashed the chip with a .bin, soldered it back on.



Put it back together.
Plugged it into my bench harness, and IT WORKS, YAY!!!

Congratulations mate.I'm waiting to attempt the same thing for my 2 bricked ones.I've got the TL866A programmer, and just waiting for the correct 40pin DIP to 44TSOP adaptor to turn up.I ordered one but its a 44DIP one and I don't think I can just remove the extra pins, so waiting time....

What did you use to solder it back? And I'm a little jealous I want that programmer and EFIlive...but my pockets say no. Still using my old programmer with an old laptop since it only supports Windows XP. How do you like that model? Are you planning 0411 projects or upgrading the LT1?

I've got a Hakko soldering station, but it can be done with just a heat gun as well. I just prefer to solder.
I've fixed 3 LS controllers now, once for me, 2 for other folks. So far so good all still working AFAIK.

The programmer works well, no issues with Win10 that I've seen.
Honestly for the price you really can't go wrong. IIRC paid like $85 for my Moates Burn2, and this one does pretty much anything.
This one was like $140-ish shipped with the PSOP44 adapter.

Hey Do you have a step by step for how to reflash?I'm gonna try this very soon with the TL866A programmer and the minipro V6.5 softwareI remember there was something about byte-swapping or something when flashing the .bin file directly to the chip?

No write up, just went off this post.

If you look @ .bin file ~4000 or ~6000 (depending on .bin file)in hex exitor the VIN will be jumbled.
it's ready to flash to chip this way. if VIN isn't jumbled then byte swap before flashing.
If you can open .bin in tuning software it needs byte swapping before flashing to chip.

Any other questions or issues just post up.
I was confused until I actually did one.
