L/16 Error message?

[68vortecimpala]

I'm trying to write a 99 5.7 .cal file to a 97 5.7 VCM. It unlocks the PCM, switches to high-speed, clears DTCs, but wont program it - it just cycles through the unlocking, switching, and clearing about 3 times before giving me the L/16 invalid response message. Any ideas?

Did you select the Force Full Program option?

If this is a vortec PCM which I assume it is based on your username the PCM's use different internal hardware. The 96-97 PCM's are somewhat of a hybrid OBDII PCM sharing parts from the OBDI PCM's. I haven't personally tried to write a 99 calibration to a 97 but based on working with the code for them they are very different in that respect. I would think if WinFlash let you write the 99 cal to your 97 it would not boot back up.

I haven't tried the Force Full Program option. Also, my mistake - it's a 98 definition file - still a problem? I also tried programming the original read back into the computer with the same problem.

I switched gears and am now trying to program a modified version of the original .cal file taken from my VCM. It does the same thing - unlocking, switching, programming, and clearing three times before giving me the invalid response L/16 code. Any other ideas? Is my VCM screwed?

Hay maybe the latest version of Winflash 2.01 available from the attached link might help you out.

Try it out and lets us know.
