I have been driving my car around for about a week now with the new SD setup.

Here is my mods list.
1990 Eagle Talon
2.0L
1g Head/Crower Springs/Retainers.
Delta 275's
Magnus SMIM/Accufab 75mm Mustang TB no ISC
PTE 56 Trim
FIC 650's
Wally 255
Dejon Race FMIC

I am trying my hardest to get Airflow/Rev As close to 0.25 as possible but the big cams are making it pretty hard.

I played with some settings tonight and got the CombinedFT at idle as close and as constant as I could but I cant get it as steady as I'd like with the Cams.

Is this something I am just going to have to live with?

My LM-1 wideband and the AFratioEST are lining up pretty decent at idle(I know it is mostly important at WOT but if I get it close at idle the WOT should be easier)

I have had this car running a week and do have some WOT pulls on the car at 15psi.

At any rate here is my idle log from tonight. I am using the EVO8 mod1 fuel and timing maps.

Are my SD cells at idle smooth enough to not cause any issues? I am mostly trying to get my CombinedFT at idle as steady as I can.

275's aren't really that big and shouldn't cause your AirFlowPerRev to be that high. I could see it being around .30-.32 possibly.

The other thing I'm unsure about is your vacuum reading. Again, 275's don't seem that big to cause a vacuum of -6 to -8 in/Hg. But I could be wrong. Might be something to look in to, unless you know that it's normal.

In regards to the SD table, I would say it's not smooth. I see jumps between cells of over 10.

Your wideband and AFRatioEst do look good though.
 
I'm running the 274's and your airflowper rev is possible to be at .25 just have to log it and adjust your cells it's idling on. Then of course play with your fuel settings. I am getting -6 hg/in on my 274's so it is normal and hard to get a consistent idle. Has to be set high over 1000rpm's at least.

Thanks for the input about the idle and vacuum readings.


There's hardly any idle in the latest log if that's what you're wanting us to look at with the new changes.

Sorry I was just posting the log so you could go back and look at the changes I made to the SD table at idle.
