about going to try jsut firing it up without the tranny though.
ill give you a call in a week or so when i have some time off work to play with it and we can see what she'll do.

I took my base FP down to 40 and it didn't have any effect on idle AFR. Reducing the minimum pulsewidth tables helped some, but if I go any lower then 1.0 ms I start getting surging and etc.

well thanks to tiago for letting me look at his file i got my car flashed and running on idle.
its running rich right now at 11.4 AFR, i forgot to turn my fuel pressure down (since i had to jack it way up for the 42lb injectors) so it was running at 65psi when at 20 degrees vacuum.
i need to turn the FP down a bit hoping that will help some (though it didnt for tiago).
idle wasnt to bad, a little surging, short trims where pretty bad at around -14
could only do idle and reving it some as i still have no trans.
and tiago is using hpt, as i am.

Using Versafueler with 96# injectors here in my 408. Idle is rich, but not too bad. Probably upper 12's to low 13's, OL MAF tune right now. Haven't messed with it a ton yet, just started tuning last night, but the truck is very streetable now. Fuel pressure is about 50-52 psi at idle. I'm using EFILive.
BTW - I only see 35% IDC at 6200 RPM at WOT

TTT anyone have any updates? I messed with this setup last night for approx 30 mins, it appears in OL SD tune I can't get the milliseconds to drop down below 1.6 and that AFR is about 10:1 BUT when its in closed loop STFTs go -30 and the ms goes to 1.3 and idle AFR goes to a perfect 14.7 playing with the offset table does help a little as far as getting it to lean out, but creates a horrible throttle response, this is my findings so far, also no matter what changes I make to the VE table or IFR table the car just wont lean out at all, im sure its a quirk of the computer as in closed loop it drops the ms down. just thought id share with ya guys as this thread has been dead.

I still don't have any problems with mine. 56-58 psi at idle, 10 hg-in vacuum, 750 idle RPM, and I can make it lean if I want to. Currently idling right at 14.7:1 with no issues. 2 bar OLSD tune. Loaded 96 lb/hr into the injector scaling table all the way down.
FWIW - my 408 at 8 psi hits mid 40's IDC at close to 6000 RPM.
