Remove AIT/MAT Sensor from Intercooler While Tuning
This may seem like a weird question, but I was wondering if it would make any sense to remove the IAT/MAT sensor from the intercooler or charge pipes while tuning and just leave it in free air.
I was wondering if this would help VEAL work better at the creating a good tune, and then using MAT corrections afterward to compensate for air density/ambient temp.
With the AIT in the intercooler and driving around for any period of time, with an ambient temp of 68f my AIT can vary from 70f-110f without trying too hard. Does this cause another issue with rich/lean tunes.
I still haven't found out how to completely solve this issue.

terrible idea.
MS uses intake temperature as a key part of it's fuelling calculation. If you give it a false reading your tune will be miles off when you then give it it's true reading.

And no not cruising will it change that much. I'm just saying while running VEAL, when you do a hard pull, the IC gets hot then you're driving around and VEAL is adjusting based on a hot air temp until it cools back down.
And as a side note, I tried running VEAL on my car at the track a couple weekends ago, it had a pretty good tune on it, ambient temps were 90f and it just kept pulling fuel out of my tune everywhere as the intercooler got hotter and hotter. Ran the car the next day when it was probably 70f outside and it was lean everywhere.

1) disable temp corrections/ego/overrun
2) tune car completely
3) re-enable all, and adjust temp corrections for different temps
side note: from what I noticed, unless your temp corrections are crazy high/low, it doesn't really swing the afr's that much. you can test this by idling the car with ego off and raise/lower the correction 5-10%, it won't affect it that much (or at least didn't when I tried it)

there's no need to disable enrichments or ego or overun. that just makes your car run like dick while you are trying to tune and drive.
just 100% out your MAT corrections table and tune the table when needed. the defualt curve is overtly aggressive.

The air density table (or whatever it's called) is a little aggressive out of the box, if you ask me. I'd try to disable it too, get fueling set, then enable to make sure it's right in most temps. Seems like it goes super lean when hot, rich when cold. Especially if you haven't nailed WUE.
