Hello everyone, well I messed up definitely. After 15 years of owning this car I finally figured I give some ecm prom tuning a try. Initially it ran somewhat ok and it improved greatly as time went on after the cam swap from 15 years ago. I used a speed pro cs1079r cam which was ecm friendly. I went to pull the stock chip out to read with my moates burn2 and sheared two of the pins on the prom chip flush off. I am gonna go to junk yard today hope to god I can find a stock ecm. I hope all my ecm relearns are going to be ok if I just use another prom chip. Here is a pic of the ecm . I really need my car to go to work and would greatly appreciate some help

The 1228746 is a cheap plug and play ecm off eBay just disable vats. If you can’t do 2732 eproms moates can hook you up with the adapter to use the 27sf512

Can I use k series trucks
tbi pickups

Yes the 747 can be used just use a 305 calibration and v8 calpak. The tune won’t help with performance as is
and Iat is not used .

I’m in the junkyard now I found a 88 k1500 pickup with a 5.7. Can I just reuse the Calpak small chip out of my original ecm

Hello, I found another 1227747 number ecm that is out of an 1988 305 tbi. I’m still confused so I bought both ecms

Don't worry about swapping the CALPAK. The 5.0l and 5.7l engines used the same one. Either of those ECMs you grabbed should fire the engine right up.

The only gotcha' would be if one of the ECMs is for a stick shift. If so shouldn't use it with any auto with a TCC.
