Hello.
After reading the manual some times i canīt find the air temperature correction map.

In the morning (cold morning) when i drive my car the A/F goes too much lean, but in the afternoon (with more temperature in the street) the A/F goes perfect. cold and hot engine is the same.

I try to see the map to change and solve the problem, but i canīt see it.
I look in the manual and in the megatune menus and i canīt find it.

Can anybody show me the road???

Thanks.

I would make sure you've loaded the correct firmware for the sensor you've been using (with AFM or no AFM) first. The correction is a part of the firmware.

i have NO AFM.

But, if you said that this kind of correction is in the firmware, please can you tell me how i can see if the firmware i have installed is corrupted???

Maybe i need to reinstall the firmware. What do you think???

Matt Cramer

Try reinstalling the no-AFM firmware and see if that fixes it.

Solved.
Thanks Matt.

So what did you do? I was having the same issues in the morning at around 40-50 deg temps. I adjusted the warm up fuel settings by decreassing a little bit from each one and so far it seems ok but it hasn't been as cold as it was when I was having the issues.

I had to recharge the firmware, as if you update from AFM to W/O AFM. You need to load the firmware that you use.
