ok, hooked up the vafc2 followed the directions exactly. when i was all done, i started it up(after the setup) and the rpm on the vafc wasnt reading. so i turned it off, re spliced the wire, and started it back up. it sounded horrible, the car wasnt runnin right at all and threw a check engine light. so disconnected everything, re conncetec as teh wiring diagram said, and left the rpm wire off. still throwin a code, but the car is running. im not sure what code its throwing tho, when i run the codes, it blinks once(long) and then goes off. is that a code 1 or 0? code 0 is a ecu problem but im not sure how it would blink out 0? also for those of you taht hooked these up before, the rpm wire i hooked it up to was green and yellow(according to the diagram) is that right?
still throwin a code, but car works...without the rpm wire hooked up. i dont understand how hookin up the rpm wire would make the car not run right and throw a code? everything else is functioning properly on the vafc.

 

ok car changed its mind. its now throwin a code for a map sensor. i dont get it, i disconnected everything except for the powers and grounds and now its throwin a code for a map sensor instead of the IAT. i dont understand how hookin this up could make it throw a code?

 

try to pull the ecu fuse let the ecu reset and then see what it does from there

 

yeah i already did that countless times. i dont think i couldve shorted something out, im goin to unhook everything and see what happens from there

 

ok, i completely disconnected the whole thing, no more codes, except for a secondary 02 sensor which i think i fried with how rich the car was running with all the other mishaps. so....i think i will just give hybrid a call and see how much they want to do it, i mustve read the wiring diagrams wrong or something to have that much go wrong, it seemed pretty straight forward...who knows. i hate electricity, it never seems to do what i want.
