Hello EvoM,

I recently got my tune done (few months ago) and the car seem to run fine. I just got back from my deployment and the weather has gotten a little more fall'ish and my car is starting to act up.

When I turn the heat on and am sitting at idle or a stop sign the car wants to shutoff. The RPM's drop ridiculously low and the car doesn't recover and shuts off.

The other issue I see now is at idle the A/F is around 16~18 while sitting at a stop sign.

I have to do some more logs but I have a race event this weekend so want to make sure its good. Let me know if anyone has any information or tips I can try!

Thanks

You can pull the battery for a bit then let it just idle for a while to relearn idle at current weather conditions

 

I have a similar issue recently got tuned on speed density and ecuboost in the summer. And with the weather change my idle jumped up to 2k on cold start up and afrs are around 11-13. I am thinking it has something to do with speed density. Try contacting your tuner and give him the logs and see if that is the issue.

 

Already messaged just waiting for a reply. I know hes really busy though so just seeing if anyone else had similar issues. It could be the SD though.
