I didn't do that. I closed to pc utility after it said the flash was complete, then I tried to connect to it with antus program to change the vin and it wouldn't connect. Then I tried the original program and then HP tuners and nothing would communicate. Then I disconnected power to put it away for the day.

I was doing this on a bench harness. Power was tested at 12.4v.

The file you uploaded has a bunch of identifying information missing from the param block. I wouldnt expect this to cause any problems but if someone (kojab?) pulls the chip and reads it back i'd be interested to see whats on there as a post mortem.

Im tempted to try the same full flash on my pcm on the bench here but as I dont have a spare that might be asking for trouble.

I guess that's what I get for trusting a bin from someone on another forum...

since I'm in the US shipping it back and forth to Sydney won't really be worth it.

Well spotted antus. It did not cross my mind (getting old) to look at that block. If they are the only things missing I would imagine a BCM re-link might at least get the engine running. This would confirm if the OS is intact. There should have been some warning to alert neruve that this info is missing. I am not sure what tool he used to do the full reflash.

If the OS is intact I have tools here to fix the missing info without lifting the chip.

I may ship it out to you if you wanna but I probably won't want it back. It would be about 35.00 bucks to get it to you and probably the same or more to get it back. I can get a whole ecu for about 30-40 bucks from the scrapyards here.

I wish they were only $30 over here!

lol yeah get a few and send them to us

He means the postage!

It might be worth trying a pcm recover with tunercat if you can - if the bootloader is working that'll probably fix it. But it does sound clearly dead.

I would try this if if I had tunercat. All I have is the avt-852 cable. I was using dimented24x7 flash tool from thirdgen.org
