3 Bar MAP scaler setting with EFILive
I'm a bit lost guys, is there a certain scaler number that all 3 Bar maps should use? I set mine the same as my brothers but then we were reading different PSI when key on engine off, should I use the MAP offset to get it to match his psi and use his same scaler number? Problem is I can't seem to get enough fuel to it when idling, and then when i hit the throttle a little bit its way to rich...
Here's a screenshot of the scaler settings and and a the tune file. The tune file is setup for SD without PE or O2's. It idles with the WB pegged at 17.0 AFR and when you gas it a little it'll go 15-11 AFR, I havent driven it yet so mabe I need to try that first, I just dont understand why its running so lean at idle! I dont have vacuum/boost ref regulator, its holding steady @ 60psi. Plus if you look @ the Injector Flow Rate table you'll see I have it set to 80#, when my injectors are actually 108# @ 60psi, but this was the only way I actually got it to run but it's still way lean at idle! The scaler settings here are setup to where the MAP reading @ key on engine off match a stock trucks reading.
Oh I also posted up a LOG, as I slowly rev it here its still showing 17.0 AFR until right before I let off the gas. Gives you an idea, I just dont get it! I have big fuel in the VE, and I've got the Injector Flow Rate set way lower than what they actually are but it still runs lean??? BTW, injectors are new FIC 1000cc Bosch, and I tried when I stalled it up turning 1 off at a time and you can definitely feel they're all working.

I don't have my laptop with tuning software here - I'll try to look at it later tonight if noone helps you in the mean-time... You want to set the scaler so it matches the 1 Bar reading you got with the key-on engine-off - sounds like you did that right. I have a 427 turbo tune with those injectors that I can compare to and try to help you out...
