Thread: 3.5 to 3.4 = NOT GOOD

BTW... your timing is going to show what it is and not necessarily whats programed into the tables. IE, if youre showing 8* KR and 9* command timing, that means the table is set for 17* for that specific cell, not 9*(17-8=9)...

I see what you're saying. But when I was WOT I had 0 KR and 9* Timing : /.

That made me choke on my water, and wake the dog up, thanks.

Haha that made me laugh. I found out some tuners temporarily install widebands fir the tuning session. So I'm going to call up the guy who rallied my tune and ask if he did that. Cuz my exhaust sounds like garbage now...

Ok so I talked to the guy who tuned my car. He said he leaned the car out by injector pulse and injector size. Was that a bad idea?

I have a AEM Uego on the way and can properly determine the AFR hopefully.

Well let's just hope the wideband will improve my tune

Finally got to install my AEM Wideband.

Idle: 14.4-15.5 ..... Im guessing not too important at idle?
WOT: 10.9-11.2 ..... ??? Rich?


My tuner hasn't gotten back to me yet, Should I tell him to restore everything on the Throttle Enrichment table and tune it through the MAF. Or do I have this mixed up? I do NOT know how to tune so this is all new and confusing for me.

Any feedback will be awesome. Thanks

Positive fuel trims is the PCM "seeing" a lean condition and adding fuel. Negative trims is the PCM "seeing" a rich condition and reducing fuel.

those WOT readings (if they are consistent) are in the ball park of where you'd want them to be conservatively.
