Hello guys, i had two questions in mind that i couldn’t really get an answer to.

I have an HPX-E Slot style MAF that im using for my set up, i was wondering if i could rewire the ACT sensor on the lower intake circuits and use the IAT within the MAF itself.

Also when using AL92, and having a wideband wired to pin 27 on the ECU connector, are both old style O2 sensors needed? or will the wideband O2 replace one of them??

Thanks guys.
