Whats a good A/F Ratio across the Lo-throttle board

[jmwenick]

Hey guys, tuning my car with the wideband tonight, wondering what it should be at for the lo throttle. Also, what are you guys running for the throttle points? Currently mine is at 10% Lo, 40% Hi. is this ok? Thanks

That's a subjective question. Really, it depends on your setup. When does boost come? Under what load? How much boost are you running?

It's a little more in-depth than just turning knobs and pushing buttons until you see some nice numbers on the wideband.

low throttle i set to 20%. i came to this since that at any rate of normal cruising i never get past that, at most about 17%

my HI setting is set to 40% right about where my turbo starts to spool

for the low map you want to tune right around 14.7. usually what you find your idle to be the same number will work across the board. the stock ecu makes alot of correction for idle and cruise based on open loop o2 sensor operation

well, I have a .57 trim turbo with 370cc injectors, tuning for 8 psi.

I try to stay in the 13's on low throttle 13-13.5 But that is because I've been through one engine and want this one to be safe. Tuning int he 14's to 14.5 will be fine. Just got to make sure it doesn't exceed 14.7

My idle is around 14.5 and my cruise is actually around 15:1. It's pretty decent on fuel while driving on the interstate.
