TURBHOE

iTrader: (4)

this is a tune type discusion but involves turbos, so i put it in here.

for afr and sd setups where you can go into pe/be when ever your in boost, what kpa do you guys actually add fuel? and in what rpm/ load condition? i ask this because you can make boost up hill with very little throttle. so do you guys go striaght to 11:1 or do you do like me and slowly ramp in the fuel staying around the 13 mark at low boost low throttle low rpm? i don't see the need for the fuel when the load is that low. am i crazy or do other people do this too? i'm talking 33% throttle and 2-5psi.

Ill have to get my laptop. But i think 2000rpms 95kPa + its 13.0 and richens up as the rpms rise to 3800ish where it goes 11.2 and stays there till shifts.

I add fuel based on boost and rpm as well, I dont ramp it to 11.5 at 2psi. I like it to ramp in and be 11.5 by 5-6psi. My meth comes on at 5-6psi also.

ok so i'm not the only one then. i use to have it go rich fast but it wouldn't pull hills well. as i leaned it out it pulled a lot better. but i wondered how lean i can go and where.

Is the to axis KPA?

yea its kPa.
Thats one of my old tunes.. i think i changed a few things around for towing.
it pulled hills great at 1600-2000rpms.. I had meth on it when towing to Kentucky after i put the cam in and it was really rich soon as it hit boost. i ended up leaning it out to 12.5-13.5ish and it ran so smooth from there out.

I believe I start adding fuel at 100kpa. Its not instant either, I use boost enrichment to roll into the fuel. It doesn't hit target AFR until like 10psi or so.

Since we're in the turbo tuning mode do any of y'all have a badass config with wideband to share. My gauges on hp look funky after the latest beta.
