IAT Sensor Question
Hi Guys,
just wonder how big is the effect on an IAT sensor to a tune?
My AFR always deeps to 10 when i come on boost?
Been playing with the VE and Scaling but its still the same.
Pls advise
Thanks

If it's scaled wrong, it could cause issues.
For example to show how much the IAT sensor can effect fueling, I used to have mine up by the TB. On hot starts where the car sat for 20-30 minutes the sensor would heat soak, read hot, and the car would idle lean (17-18 afr) for about 30-60 seconds. I have since moved the sensor down to right by the intercooler outlet and that issue has gone away.
