Is there any other tool than Dimented's that will write bins using the AVT-852? BlackBoxFlashApp doesn't work on my 411 PCMs. Where as Antus's LS1FlashTool works great, it just doesn't write.

I figured it out. On the bench I had wired the ignition to power. It needs to be switched separately before powering off in order for the write to occur.

I'm missing a step or something. I can program a new VIN into the 12200411 with Antus's tool and the atv 852 cable. But.. it doesn't stick. It's there as long as I don't cycle power. I powers cycle and the old VIN is back. It's useful only as far as I don't burn another license with my tuner software.
