Nobody? I guess J-bodies are a dying breed.
Something is missing on these!!
Force open loop and you get very rich commanded. WTF?? No shown tables are indicative of this.

Good engineering is simply finding the right wrench to pound in the correct screw.
I've learned this summer that if you tune a Jbody with the a/c on in open loop, you get 12.9:1 commanded AFR

Theres many tables in the ecm. 3500+. We don't see them all. Its only what is available in hpt. In open loop your using those table you can see in hpt but they are there. open loop your disregarding all sensor values for calculations. so the factory decided for what ever reason be it emmisions or drivability etc. to lean to the rich side to be safe.Originally Posted by BennyHHR
