I hooked up my tps to a switch, literally an on off switch on my panel. followed the procedure on how to learn the tps turned the switch on/off a few times then the controller had learned the signal. then I just turn on the switch and program based on boost.
at my elevation 0 psi was not triggering it to go and with my tightish converter and a large single i couldn't get it to spool. called nx and they told me how it reads vaccum as well, set the boost to -4 psi and it worked great. so to stage I turn on the controller, power brake, turn on full throttle switch and let the programming take over, love it.
