I don't have much to contribute, but LB7 ECM's are 01, then 02-04 are the same(03 and 04 use the same OS), and 04.5-05 was the LLY(LB7 stopped when 04 production ended). I did more than my fair share of LB7 tuning with efilive. 01 has always been the bastard child with all the flashing quirks that i...

Do an 0411 swap on it. The black box is not a very good controller. It is supported by hptuners, efilive, tunercat, and I think lsedit, but most skip tuning them, and go to an 0411 because the black box even with tuning software doesn't run as well as an 0411 swap does.

Are you switching from the 0411 to a p59 pcm? I can try and get you an 04 blazer .bin tomorrow.

If it was mine, I would abandon the operating system looking for a 24x signal and go with a v6 truck tune file from an 05. It uses a low resolution crank sensor signal that is very basic. It is a 3 pole crank reluctor of 3 on and 3 off all at equal 60 degree spacings. And it is already setup for ele...

Running into a BIG issue trying to do a full read on a 0411 PCM. It's loaded with a 12208322 OS for an 02 C6500. It was flashed in with a TECH2 and all went well. The PCM works fine, can request the VIN and read properties, but as soon as you go to do a full read, it uploads the kernel's, then freez...

My understanding is the trans selection table is there, but should not be used. It's there so you can see what the tune is setup for, but nothing more. Changing the trans type requires a segment swap, not just a flag change. If you change the trans type using tunerpro, it will corrupt the .bin. The ...

Any ETA on LB7 ECM flashing? I picked up a used ECM, and just my luck it's corrupted. I know about the bootloader bypass to force a read or write, but I don't have any way to replace the vin, serial, and BCC code other than a cloning program. I found a complete .bin file to flash in, but I have no w...

I haven't flashed it yet with my tech 2, only went into the sps to get the data(my tech2 clone won't do pass through I've found, but will accept a tune to flash in on it's own). I don't have the numbers off the PCM in front of me, but it was out of an 01 S10 and wasn't supposed to have been locked a...

Is it possible EFI Live somehow locked the bin file the last time it was used to make changes to the PCM? Don't think so. I just went back in and read it out using the stock key with no problem. I even went and flashed a different cal file in it making sure there was no locking protection enabled, ...

I guess I'll try manually inputting the seed key my other PCM uses and see if I can read it then.
