rich P.E

[ke5gnz]

]Hello I have been out of this for a while I am have an issue where PE does not change no matter what value I put in the blocks. the truck was FI and now is NA. and when I go into PE it wants to run at .7** lambda. no matter what I tell it to. I have read the sticky and changed accordingly with no such luck. I have to be missing something but don't know what. I have even rechecked the MAF to see if that was causing. still nothing cant be ve as it is disabled in MAF tune. I would greatly appreciate any and all feedback. attached is 6-19-15.hpt


ok here is the correct log that one was in 2014 when i got hp tuners and was trying to undo what a friend of a friend had done here is the correct log 6-19-15-2.hpl

Think you can get it to knock anymore?

I spent the better part of an hour looking over you tune and couldn't find anything that was making it do that. What vehicle is it on? I'll try to find a stock tune to compare to.

[ke5gnz]

I think you for that. you at least responded out of the 96 or so people that have looked at it

I don't know if this can cause a problems, but I would change the dynamic airflow disable and re-enable to something like 200 / 100. Set the way you have them you could still be using VE under 2500 rpm.

What vehicle is this file from? Sorry if I missed it, but didn't see it stated

[ke5gnz]

will change and see if that helps. It is a 2010 silverado with the aluminum 5.3 flex fuel truck with flex fuel 6.0 injectors long tube headers, off road y pipe 4 inch exhaust, 4 inch inlet with ls3 throttle body. lingenfelter 4 inch calibrated maf almost forgot it has an LSA camshaft

thank you once again. it just gets frustrating when there is a lot of knowledge out here but few wish to share. I am not doing this for a business but for my own truck.

[schpenxel]

Looked through a stock one and compared, I coudn't find anything that made sense as why it was doing that, sorry. I hope someone else can find it

[smokestack]

Mobile. But did you setup the injector flow rates right? Did you tune the O2 sensors for the headers?

[ke5gnz]

yes it ran great when FI. I copied the injector data from a stock 6.0 flex tune and everything from fuel millage on dash to fuel used has been accurate MAF tuned right in when I installed the injectors. tuned to o2 for headers? don't know how to do this will reserch tomorrow and see if that has anything to do with it. truck runs good just rich in PE mode and lags some at full throttle, let off a little bit and starts to pick up . than you
