I'm going to look at a 1/2 ton GMC pickup pretty soon. I'd like to look at the ECM output using TunerPRO. It has a 4.3L Vortec V6 with a 5 speed manual. I've tried searching the net, but I can't find a definitive answer. I need to know which .ADS file to use with my moates.net interface and tunerpro. I do have a Camaro too, but I already know what ECM it uses.

thanks for any help

 

i just pulled my stock computer of my 92 4.3 5 speed and it says
SERV. NO. 16144288

 

Thanks for answering, it may still come in handy. It seems that three or four different ECMs have been used in these trucks. I went to look at it, never even bothered ringing the doorbell. Too much body work needed.

thanks again
