Hey has anyone messed around with this table at all? Looks like the software equivalent of an automatic choke to me. My LS1 doesn't maintain the programmed idle speed very well until it goes into closed loop after a startup (hot or cold,) which isn't very long but still irritating.

Well I've been working with this table and found that scaling it back by 75% has really improved my cold startups with the new cam. Just thought I would post this to help anyone else that may have a poor idle before going closed loop.

I've never had cold start problems.Did raise the cold idle up 100rpm though.

Actually it helped with warm startups as well since there is a brief period of open loop operation even with a warm motor.

Thats good to know.I'll give it a try.

ls103

the fuel air multiplier table is air temp vs fuel ie fuel is added when air temp sensor sees a cold value it will add fuel accordingly, my car lost power when iat was below 20 degrees celsius reason being that fuel air multiplier was adding 10.0:1 af ratio. does this make sense?

So did you modify the table to lean it out?

ls103

yes i did. my car suffered big time in the heat i just changed the fa multipler to command 12.8:1 and suprisingly it was fairly close. it doesnt drop off as much power now (the car is tuned without a maf makes it harder to perfect)
