yes i know how to do it, i was just basically answering my own question since no one did before i messed with it. From what i logged the 1% i changed got me .10 change in a/f (pretty much what ur sayin). And once again this is going off the a/f pid which is how accurate? and how do they get this, im ...

well since nobody messes with WOT PE around here nobody will prob care but, after logging tonight 1% change equals .10 a/f change from what ive seen. i just hope the a/f logging pid is as accurate as they say..

bump for a chump^

got it all runnin today went and did a quick log, got a question. how accurate is this, i mean it doest really bounce around all that much like a believe a wideband to do. if i rem reading correctly somebody compared it at a dyno and it was really close, thought id ask..?

edit: searched and found ...

ok. pm sent on a different question, thanks..

so bottom line is you have to have a labtop in car running dataview to get the a/f pid and doesnt show up just using the handheld correct

you all getting this thru dslogredux or wideband? i havent looked thru all the pids but was under the asumption that there was no a/f value on the u7193..

bump for an answer to my question^

just curiious, whats the commanded wot a/f ratio for a u7193 diablo tune on a 04 gmc with 5.3 if i may know plz?

it doesnt perform any different while this is happening..
went out and watched again and sure enough at 25%TP the ltft's change from 4.xx and 5.xx to .78 and 0. @2100 ish rpm
must be ecu switching into saved ltft's?

ok i re-read my post and it sounds a little different than what im tryin to say.
constant driving at Tp% of 23 or below= 4.xx ltft
constant driving at Tp% of 25 or above = .78 ltft
both on cruise on flat road
im sure i am fine just a little curious, last time i watched data i noticed it would change ...

ok adjusted my ltft's the other day, and today i go out for a ride to check to see what had changed. while riding today i noticed while crusing 60-65 at almost 2k rpm my ltfts change with throttle position. ex. anything below 23%ish throttle my trims are 4.xx, but go over or around 25% throttle and ...
