Starion 2.6l g54b with DSMLink, AirflowPerRev good but won't idle smooth

[lfatty]

Hello y'all. I have a Starion with a 1g ECU, harness, CAS, ect.. with DSMLink. Anyways I'm running 1600s with e85. I set my global to -58% and my deadtime to 450. Car starts right up and runs good! But now off to tuning what should I look for as far as airflow per revs?

Should I add the percentage different in CID? Thanks!

All I have to say is dam that looks nice and clean. Sorry I dont have a answer to your question but I had to make a comment.

A 2.6L at idle should be about 0.31 gm/rev.

yea i cant answer your question either but that looks amazing. Do you have any pics of the whole car? Goals? (power wise)

That thing is probably going to be one hell of a drift car and drag car.

Sweet thanks! Hopefully the tuning will go alright.

I'm hoping for 450 at the wheels at least. Ill post a pic in a few

Someone asked the same question for a 2.3 on the Link forums and Dave said that AirflowPerRev at idle is roughly proportional to engine displacement, so if you take the standard .025 gm/rev on a 2.0l engine you will get (0.025/2.0)*2.6=0.0325 gm/rev.

Ok my airflow per rev values are at .31-.34 and my LTFT's are at 0's but the car just won't idle smooth. It goes up and down from 800-1100rpm. I don't have a ISC of any sort. Just a 65mm Ford TB. Oh and if you rev it, when it comes down it will die.

Ok I did some searching and sounds like I need a DSM TB

Thats all fine n dandy but what about when its got cams? Those numbers dont work out so well, we all know, when you put a set of 272s in a 2.0. Its very difficult to get .24/.25 and likes to b closer to the .29 mark or .30
