Cold start issues with a properly set idle are usually fuel related. What kind of AFR's are you seeing at 800 rpms before it dies?

It was really lean. There was a hole in my fuel map right where it wanted to idle, I fixed it and made it more stable, as in it no longer just dies, but it's still trying to idle at 800 when it should be at ~1300. The AFR's I'm getting when driving cold are still leaner than when I'm warm. Is this by chance something to do with warmup enrichment? I'm just guessing tho...I can log it later when I cold start it after work today. Anything in particular I should be logging beyond AFR, Engine Speed, etc?

thanks for the post, I am in the process of tuning the car and that really helped me a lot!! Car is idling pretty good. I am stock now on the O2 FB, you say to set the table to 14.7 on the idle cells. Im I in the correct table? If so, they look pretty off! Any suggestions, thanks!!

It looks like your load breakpoints are off. I like to use psi instead of kpa. It's more relatible for me.

Anyone still watching this thread? I have idle issues, my car apparently has had 1000's spent but my idle learned value is always in the red 14% plus car does idle but doesnt do what it is supposed to do. It is on a series 2 ECU running latest firmware and latest tuner software. Could set up teamview or something for someone to have a look :-)

Thanks

There is a Youtube series specifically for the AEM V2 by "Jonathan Fasking" I believe, where he goes through the full setup and tuning of the device. You may try that.
I know that if your fueling isn't very good, you'll have trouble everywhere else.

If anyone is going to be able to help, a detailed info on current setup would be needed.

Jonathan Fasking U-Tube training series on AEM EMS is an awesome resource. 16 Videos in total. I am an EFI University Certified Tuner and have attended AEM advanced course training and AEM V2 specific training and his videos are spot on. Sub'd for future ref.

Old thread but this info was very useful so I figured I would ask here. My Evo was stored for many years and ran great on an AEM v1. Took the car out and went over nut & bolt and finally fired it back up. It is a little tough to start when cold and the idle would surge from 900-2300 which led me to this thread. it otherwise is running well on the previous tune, After adjusting these settings I got the car to idle smoothly at 1200 when up to temp but when I blip the throttle it hangs and sits around 2000 when off throttle pretty much indefinitely. I'm thinking there is an enrichment somewhere that isn't tapering with temp or RPM somewhere?

It is also seems to catch faster when starting, but stumbles at 800 for a few seconds then surges to 2000 before settling to 1200 after ~10s. The injector all checkbox is on and the crank timing is 10 deg. I figure this was affected by the idle settings.

I know this place is pretty dead but hopefully someone with more experience than me can chime in.
Thanks,
Bill

Hey Bill. With your laptop connected and AEMPro running, go to your main Idle page. Make sure the Parameters window is active, and then press F6 to start logging. Blip the throttle to get the idle to surge and hang. Then, press F6 to stop logging. Email me the log and your calibration files to [email protected]. I'll take a look and see if I see anything out of the ordinary.
