I put my VAFC in this last weekend, and everything went very well as far as install, and function afterwards. Today I was driving on the autobahn and at about 115mph my CEL comes on and the car started feeling kind of sluggish in the mid to upper RPM range. I hit 5500 rpms and it (CEL) came on. I had bumped the fuel up a small bit around there, and reset the vtec engagment back to 5500 from the 5800 the VAFC defaulted at. Other than that I haven't messed with it till I can get to the dyno. Anyway, I couldn't pull a code since the CEL went away after a turned off the car, and restarted it. I set everything back to default for now, but does anyone have an idea of what happened? Is it i glitch with the cars systems? And what the hell is the VTM wire for (I have yet to find an answer for this one)? Just incase you don't know, or the screen name doesn't give it away, I have a 92 VX with a 93 B16A2, have driven it a couple thousand miles no problems.
