    random timing added- 96 LT1 OBD2

    What tables add timing in the Jet DST software. Sounds simple, but ive played every table I can think of and it still adds random timing. I set my closed TPS to 32* but my Innovate LM2 log shows 39-40*

    I have max timing supposed to be 41* but again the log shows 45-46* at WOT?

    Any help would be great. For those that run Jet Dst I can send you a copy of my tune, and screen shots of the logs.

    Thanks.

    Ok so I went back through my tune again, I still cant find out where this extra timing advance is coming from. My timing is showing 43.1 flat on my log no matter what I do.

    have you zeroed the egr timing adder table? how about the coolant temp spark correction table?

    sounds obvious but..

    I did actually. Its still showing 43.1 no matter if it's at idle or load. Im trying zeroed advance correction tables now to see if that fixes it. I dont run more than 40* anywhere in my VE tables, so for 43 to show up its kinda odd.

    I went back at zeroed my min spark advance table. It had random 12* at 1200 for some reason. That knocked it down to 37-38*. Id like to be lower still, will it drop more if I add fuel or raise rpm?
