but even if he HAS to use a boost reading from a higher rpm, it would still be better than my original brain buster idea of using the air pump to red line. so i wouldnt rule that idea out completely. but i truly personaly feel to trash it and get a midpipe. i am just giving the man ideas...sheesh

Well, I checked the wire coming from the ecu and there is voltage when the pump shuts off. I then put 12v on the pump itself and it held up just fine. Then for ***** and giggles I hooked up my old ecu, and it still didn't work. I'm about to start selling parts of my home theatre and some old RX-7 stuff so I get the PFC, I'm so confused. This is harder to troubleshoot than anything I have done on this car. I figure I'll get a PFC & Midpipe, junk the air pump, and when the egine gets replaced (hopefully 5-8 years from now, it's new) I'll throw in a new wiring harness and air pump. Anybody work at a bank that will give me a loan for 1300.00?? Just kidding.

. If it is there maybe you just ran into 2 bad airpumps? I know what you mean... trouble shotting this crap sucks sometimes... but you'll never forget it when you figure it out! 
Maybe I should pull up the wiring diagram and see what your looking at.... got a page # by chance?
