hi guys, i have an apexi Turbo Timer with A/F functions...
the setup is for a turbo engine...
i want to ask you guys opinion on whether the A/F reading is accurate a not compared to another aftermarket exhuast temp gauge...
do i need an extra sensor for the A/F readings or could be tapped from my car?
would it be better if i got a defi BF exhaust temp gauge compared to the apexi a/f reading...
users, any feedback??
