Hi guys,

I have been trying to get TunerCATS to work for my application. I currently have 2 1995 B-Body PCMs, and I intend on reflashing one of them so it will have an M6 F-body tune (also 1995).

However, when i patch into my PCM, i get the error:

"Invalid Response from PCM"

This happens about 3/4 of the way through reading the PCM. I am using a cable purchased from ALDL cables.

has anyone else had this issue? I have followed all the guidelines set up by TunerCATS -- grounded engine, fresh battery, all programs on computer turned off, disabled internet etc. But still no dice.

I can read the VIN number information -- so i know the cable is working. Any ideas?

The car is a 1984 Jaguar XJ6, with a 1994 Camaro Z28/T56... The harness is from a 1996 Impala SS, but the pin-outs for the OBD connector are the same...

 

Try plugging the AC adapter into your laptop.

 

had the laptop plugged in the whole time -- i've heard that some people hook a trickle charger to the battery, but that didn't work either. I've also heard that lowering the baud rate will help as well, although I haven't tried this yet. Has anyone had experience with this working?
