rich at idle / SD

[Boost]

What could cause me to be rich at idle 14.63 is commanded but I'm seeing 12.0 ish on the wideband even as I lean out the VE table

Stock injectors?

Data log this morning. The injectors are pretty much dialed in to the manufacturers specs and the car runs well otherwise

[5FDP]

Post the file please.

Yes sir I think I did let me know if you need something different or better. Thank you for looking

[5FDP]

That was the log, I want to see the tune itself.

I was going to suggest cutting the min fuel milligrams under the transient fuel tab in half. Often larger injectors will require that number to be dropped. I think stock on many calibrations is like .0410 or something like that.

5FDP mine are 36 i cut my mg to .031 or somthing from .040 and it was much better. He might benefit from this hp 12.0 is a big difference.
Also does he have the right data

Thanks guys, will post tune this afternoon. I experimented with that before, however mixed results as it did in fact lean out the idle beautiful but caused lean knocking somehow in off idle areas. I am more than willing to revisit and learn, and do it better

Here is my current

Which 42lb injector out of curiosity

You have not failed the MAF correctly

Airflow > Dynamic > high rpm disable > set to 8000
Engine Diagnostics > airflow > MAF Freq fail > set to 0 or 1

Get rid of your MAF channels and add injector pulsewidths

Why is your throttle voltage .06?

Thank you, will do right now!!!!!!!!!!!!!!!!!!!!!

I am running a 92 mm throttle body with an adaptor to stock LS6 intake and I had to rape both the IAC and the TP to fit...

I will humbly and gratefully listen and follow any good advice. Throttle hangs until I stab it to return to idle. Mileage is good 20 mpg around town. I race on the 2nd. I have a 9 inch with 4.56 gears and Racetronix 340 pump. Thank you again

Not 100% sure.on ls1 but the tps should be around .5 to .6 or something not .06

Also noticed your injector data is different than the Ford to GM conversion data i have. I could share it with you later on.

[Boost]

good morning everyone. updates on this issue. First of all here is the new tune I uploaded based on your recommendations

[Boost]

Observations:

Idle mixture did lean out a tad. I cut the min transient from .041 to .030 or whatnot and at first it seemed to move a half a point in the correct direction. But eventually realized it still settles at 12.2 so I may want to cut it all the way in half meaning .020 or whatnot if it doesn't affect anything else

[Boost]

Also, the throttle is less likely to hang when it's supposed to idle, it did it only 1 single time in the entire test drive home from work last night and to work this morning. However I still think this may be a mechanical issue meaning the throttle plate or cable or something with the sensors in the throttle body
