Did you read out the stock tune first and save it? If so do a "full reflash" with your original stock tune.

Try unhooking the batteries for 15 min and try again. Not sure if it will fix your problem but I've had a no com error on my LLY's after trying to flash with the ABS relay still in.

Damn Ne-max beat me to it.

When you read out your stock ecm file did you save it?

don't buy an ecm, yours is probably fine. Many people have "bricked" ecm's and recovered them with no problem.

If you can find your stock file try doing a full reflash with it first.

I tried doing that but all I get is 0101 no communication and when I go to the bbx there is no pids for E54 lb7 only a ext in both spots where it should be,i think I eraced that one then programmed the v2 with that,Playing with it and not knowing what I was doing.How do I get the lb7 E54 back on the pid list?:confused:i used the v8.
