that maf limit sucks!! xlr8nss will be able to spit out all the options to get around that but it sounds to me none of them are exactly figured out yet, i am hoping someone has a nice little black box to sell me that will just fix the problem and let us read 100+lb's of air and they need to develp that box soon!!

 

Thanks Bigtex, thats what i figured the recovery rate thing was. Sounds like im gonna have to do some researching on the MAF limit thing

 

BigTex, do you think the headers are causing most of that KR?
I have been fighting a mystery KR at around 3600-4000rpm for some time now. No matter what I did with the timing or PE it wouldn't go away.
Recently I tried changing the 'MAP to Enable' PE mode from 55 (truck value) to 15 (car value). This seems to have helped. I'm still refining the tune, but its getting there - ( timing 26-27*, O2's ~910, max KR ~1*).
My original impression was that this was a MINIMUM MAP to enable PE, but somebody else said that it was actually a DELTA MAP to enable PE mode. If it is truly a delta MAP function, I would lower it for performance applications...
BTW, I haven't noticed any negative effects.

 

I'm not sure what is causing my KR. I need to really sit down and go over some logs.

I'll look into that PE feature. You might be on to something.

 

tex are you running factory fuel pump and injectors?

 

At this point, yes. I'm out of injector, so I need to change before I have issues.
