Safc II part throttle boost tuning

[3.0 GT]

Hey guys, i have a fresh 7m with 550's, lex, 57trim ct26, exhaust, etc.., and im having problems with part throttle boost running 14.7 afr. On the safc II my throttle points are set at 69L 70H with a perfect WOT tune. All of the low throttle settings are at 0 because it runs right at 14.7 in closed loop. but How can I tune for when i am boosting on just part throttle? And it makes boost at relatively low throttle which is becoming a problem.

i'm actually interested in this, as i'm trying to figure out what is a good LO setting and HI setting.

i had alot of issues with this as well. i got it pretty decent with low at 30 and high at 70.

Anything for tuning below 70% doesmt matter as the ecu is in closed loop and the safc will just be fighting the stock system, which will ultimately win the fight

Yeah, Just tune under WOT otherwise the TCCS will correct on its on and get all out of wack

So its ok to boost at 14.7, as long as your not wide open? That does not sound right.

isnt there a how to guide somewhere on here. of how to correctly tune the safc2

I blame a poor tune on the safc2 for my engine melting number 1 piston. because in the attempt to get a good all around low and high throttle tune,,, it leaned out at full boost wot... 17.4:1 Afr's and 16 psi from a t61 dont mix,,,,,, oh well such is life,,,, Take that car to a tuner
