Did the apexi avcr electronic boost controller ever worked on your setup? or problem since first start?
I never had it working. I wired it in to my car and that's when the tps problem started. Removed it from my car and problem went away.
I remember there were some that Ecmtuning didnt recommend due to the blowing the BCS driver circuit. The IR 3 port from them is relatively inexpensive if you want to stay with what they recommend.
I will have to go look at the site again and see if I can find that list.
Luke do you have a wiring diagram for the apexi
wired it up like the manual says to.
