I would start by zeroing your fuel sliders. They only work in WOT(open loop) settings and really aren't the correct way to get your fuel where you want. First thing I look at is your AirflowPerRev and it's pretty high at ~.32. You first want to get that near .25 which means tinkering with your 0 and 50Hz settings. Doing that will lean out your idle a bit so you will want to add injector deadtime to keep your fuel trims in check. Things should look pretty good after that so I would take another idle log and post.

PS - Not sure why you would want to target 8.0:1 AFR in your open loop table. IMO that should be at or near 11.0 for 93 octane fuel.

Along with the values above, your ISC is in the high 60’s. You need to adjust your BISS to get this value around 30.

The fuel setting was just me understanding how they move up and down getting a feel for the program. I just forgot to set them back to zero. Yea I want target AFR of 11.0.

Thanks

Thanks will adjust the BISS. Once adjusting the BISS I have to Mafadjust to keep idle right. Correct

 

[BoostedBeaver]

No, the BISS adjustment will not alter your fuel trims or metered airflow. It will set your ISC to the optimal position to maintain a steady idle.

how does it look now. Thanks

As stated by Mindblowin, you need to change your fuel tables unless there is a reason you are running such a wild table. Copy the Evo8 table attached below for both DA fuel tables.

You are also pulling a lot of timing out of your DA timing tables. Is there a reason you are doing this? If not I would suggest copying the EVO timing tables too.

Your CombinedFT are at 20%. You adjusted your 50hz sliders to get your airflowperrev in check and you did not add deadtime to the fuel tab to compensate. You need to add deadtime until CombinedFT are around 0%.

Its not necessary but you may want to add a little back to the 0 and 50hz sliders so that when you average a large idle section it sits a .25 although you are close at .24 for the averaged selection

10). Electrical system
Car off (not running): 12.4 volts
Car running: 13.9 volts

If your battery voltage really is 11.9 volts (what you log is reading) with the car running, you may have some charging issues that need to be addressed.

Your ISC averages 27 so its pretty close. If you want to, adjust the BISS a tad more to get 30 over a large averaged section of the log.

My car is finally back after Crank Walk this is my latest log I had the car idle for a bit and then took the car out on a cruise let me know what you guys think and if you see anything that many need correcting. Thanks
