Still a little bouncy when in closed loop. PE looks pretty stable though.

I would switch it over to read lambda instead of AFR. Lambda is a more meaningful value, easier to think about, easier to tune with, and applies to all types of fuel. With E85 and other ethanol fuel types/mixtures, 14.7AFR=stoich doesn't apply.

That's just my opinion.

 

Okay, I'll read on swapping it over Lambda or if its easy just tell. I'm just getting started with this side of the builds. I hope to have HP Tuners shortly it "tuned" in EFI now but would like to find a tuner to tune it correctly before I buy HP it so I can learn a little more about it. there is a few mods I'm not sure on how to map over.

so it look better with the bouncing? It has never been tuned from cold or correctly for that matter. when dose it supposedly come out of open loop?

on the WOT run....were you still at WOT when it maxed out the lean setting? AFR looked good until that spot.

 

Sure sounded like it

 

yup, still gaining when it went lean. I guess true tune is what I need now. Just not any of those around here. any one want to take Road trip?

Stupid question, I know there is no stupid question, just stupid people asking questions.
I'm tuned in EFI live now. If I get HP tuners and pull my file will it stay the same or do I have to do major changes to get it to work with HP. I'm just not sure with it going from a 5.3 to a 6.0 and 60r to an 80e and different injectors. just confusing myself I think.
