V5 tune
Anyone else get a check engine light for bank 1 and 2 lean codes....?
Got the tune on New years eve morning and later that night the CEL Came on. Cleared it and drove home nothing......next morning went to my girls house and boom CEL again.....
I'm wondering 2 things.....Jersey is been 40+ in the day than under 20 at night cause I live right near the ocean. (Literally 2 blocks) I wonder if the temp difference between the day and night is affecting it? Or the file they send in the email is based off the weather out there and the difference is causing the code to pop up. Other than that This tune is by far better than my old renntech tune and these downshifts are absolutely amazing.......
So happy with it, just need to work out this issue.

no CEL here either, I believe I've seen EC recommend to someone before to drive around with the mygenius in logging mode and send the logs for review.
they will need data to look at to determine how to adjust the tune if required, but i'd certainly reach out to them first

gas doesn't mean anything, Lol...pretty covinced its all marketing, I've been using 91 on a 94 tune for months and had zero issues, infact my MPG is a bit better with 91, 94 it burns too fast or something
