Previous tuner left it like this. Car was supposedly tuned in SD. Car stays in open loop with the message (CL- not ready) 100% of the time. Doesn?t use LTFT only uses STFT and they are -8% at idle and while cruising they are -12%?AFR at start up is 11.0 and will work it?s way up to maybe 12.2. While crusing it will get to maybe 13.0 and when decel it will go as rich as 10.8-10.0?but, when you smack it and go WOT it will hang at 11.0-11.2 all day. When it goes WOT the STFT will go to 0% and stay there.

I was wondering if starting at Min injector pulse width to lean it out at idle would be a good start.

The minimum injector pulse width is set at .729 across the board

The transient min fuel milligrams is 0.032

I can send a log to an email or attach one here if I can figure it out haha. This is first day with HPTuners and just got the car a week ago so trying to get it dialed in. Thanks in advance
