Can anyone please let me know what base air correction value's are on the Microtech. Running a 20b but I assume they will all be the same. Also at what air temp do you usually find these can zero out? I assume engine bay temps have more impact than ambient air temp so it won't necessarily be climate specific.
thanks in advance for feedback.

 

You want to have 0 at what air temp you see the most. i.e. fully warmed up, and whatever temperature you will be driving the car at the most.
The correction are exactly what you think, corrections for when unpredictable situations happen.

Your water temp should be the one you should tune first. Most don't tune for air temp correction, because with the microtech and no IAC (Idle air control) you won't get as smooth of a tune.

 

I though that might be thenanswer but just checking.. I would imagine winter and summer temp to be quite different as is bonnet up or down! I seemed to be around 18-20degs the other day droving around in 20deg or so ambient. So.i guess zero out by around 13degs or which ever the table offers near that.
was more a case I wanted to check mine is currently at the base setting you get from Microtech as I think it might not and might zero out earlier
