2000 K3500 5.7 Liter Flash

**dave w** · 12-23-2015

I need help getting either a .bin or .cal file for VIN #1GTHK33R0YF450300 / 2000 k3500 5.7 Liter.

Attached is the .bin file I read from the PCM, and the error message I get when I try to open the .bin file. I tried EFI Live, and got a similar error message. Moates.net is closed.

Has anyone ever seen OS 9384185?

Thanks in advance,
dave w

Interesting. GM Cal ID checking tool lists that as the correct OS. It also shows an alternate fuels ECU for this VIN. Is the vehicle natural gas or propane fueled??

CNG, or more accurately, it was CNG.

CNG tunes are not supported by TC, EFI, or HPT. With the P01 and P59 PCMs the OS would begin with a "5" for CNG applications. The Blackbox OS still begins with a "9" in CNG applications.
