02 Chevy Tahoe - Drive by Cable or Wire?

[VetteNut]

I've got a PCM out of an 02 Tahoe I put in a resto rod I built (81 Corvette with an LS6, T56, Supercharger and C4 Suspension with a Tube Frame). I'm using a Street & Performance Harness. I've got a Drive by Cable Throttle Body on it now. I used a tune I did for another SC'd LS6 that I did and just updated the necessary tables.

Engine starts and stumbles a bit then stalls. I'm getting nothing but 0 TPS and throwing a "[PCM] P1518 - Electronic Throttle Module to PCM Communication (SES) (Pending) (Old) (History) (Current) (Immature)" code. I'm thinking the Tahoe must have been Drive By Wire or I've got something else going on.

If the Tahoe was Drive By Wire I assume this PCM has to go and get one from a cable driven car right? Or can it be made to work.

Thanks

ps: I turned VATS Secutity to NONE.

Use a Camaro calibration as they were cable throttle and copy your S/C mods to it.

Do you mean use a Camaro tune and upload it into the existing PCM that I have? I do have an 02 Camaro tune I did for someone. I could do a "Write Entire" and the just Timing, Airflow, and Injectors to start it up.

If the same PCM can accomplish the Drive By Cable run, what are the differences?

Thanks much.

That did the trick, thanks.

Took an 02 Camaro Tune I did for someone and did a Write Entire. Puppy started right up and purred through the open headers with music to my ears.
