You're logging the wrong request. Read up about the 2-byte stuff in the chrome thread.Quote:

i have the same lean spike with a 3.0 engine with blow-through.
i have turned up the delta multiplier a good 6 points across the board and i still havent seen any change to my lean spikes. I gotta play with it some more.
i will do this and report back! i didnt even see that... i am wearing the dunce hat, i swearQuote:

also, i just did a datalog and hit 2575hz, so the 2 byte thing worked much better. i am still on wastegate boost haha
Holy shit! That's pushing some air! What load numbers are you seeing?Quote:

i dont have opposite trims, chris... but mine were at 12.5; i am going to reset the ecu. I think that my oxygen sensors are no good. may invest in some new ones in the very near future.
greg, i am seeing around 200 on the load side of things. im curious to see what happens when i start turning up the boost past wastegate haha
and just as an update: the 2 byte airflow really helped a lot more. i got the tune reasonable up top (11.5 afr) by messing with the VE table, but that dang lean spike is awful. having a hard time figuring out how to tune that out.
and when i went to take the car out to turn up the wick, one of my oil return lines gave out. im not sure if it was the fitting or the hose itself, but it started spewing oil and i was done. so i will fix that when i come home from texas, then tune it some more. hoping for some big results!
