2G ECMLink idle tune

[Kpro22]

Is my deadtime to high? It's currently 680dt on FIC 775 injectors.

The number seems high, but your combinedft looks good and the wideband is nice and steady. I did notice toward the end of the log it looks like your fan or something cut on and voltage dropped significantly and the mixture went lean. You could eliminate this by going to the injbatadj tab, and adding some deadtime to the 12v range.

Thanks for the tip, I'm going to try that tomorrow.

If you want good tuning advice, you need to fill out the template below. We use the information in the template to help evaluate your tune. This format allows those willing to help you to easily verify your car is in good working order before time and effort is invested assisting you with tuning advice. You can't tune a car that's not mechanically sound.

Here's the format ---> http://www.dsmtuners.com/threads/wa...r-receive-no-replies-from-the-wisemen.443297/

Here's an example of how to fill it out ---> http://www.dsmtuners.com/threads/first-time-log-wisemen-just-look-away.495794/#post-153536533

Next, make sure you're capturing the correct values for the type of feedback you are seeking. See here for what values to capture ---> http://www.dsmtuners.com/threads/list-of-values-to-log.444831/

Lastly, update the mod list for your car if it's not already up to date.

Is my Deadtime too high? It's at 670 DT.

Your TPS needs to be manually adjusted.

Your deadtime is definitely high for 775cc injectors. However, your target and actual AFRs are lining up, so you'll probably need to make adjustments to the low HZ MAF range if you want to drop it down.

You'll notice throttle delays and poor idle if the deadtime is too out of wack.

Is the car running poorly, or what?
