The only part of the TPS you really need to be concerned about is the IDL switch. With the AFM, yes it could measure the proper resistances and still be bad. With the ignition 'on' but the car not running measure the voltage at Vs while you slowly move the vane through its full sweep. The scale...
Most shields aren't going to help much either. To put it in astoundingly simple terms: you've got an intercooler capable of reducing air temps 10º... which air is colder after it passes through: the 70º air from outside of the engine bay or the 90º air from inside the engine bay. Of course we're...
I thought there was only the hose for the PS which connected to the accordion.
The fuel pump resistor and relay do not cut power to the fuel pump under any circumstance... well, unless they're broken. The fuel cut off is in the AFM, that's he FC switch; Have you bypassed that?
Like I said...
I wasn't questioning if the ISC was working... I was questioning if it was placed where it would move the vane in order to close FC... I thought that was rather clear.
The whole thing dying if he steps at all on the throttle gets me, but it's easy enough to test if part of this is a pump...
The only dash cover I'd use would be a molded to fit FG or CF plate. It would look 1000x better than a carpeted dash... had that in an old Escort we owned... just killed me.
Have you done this? I'd like to see pics!
Just source the vac from the line which runs to the stock boost gauge and CC.
While you're fighting with this, try just hooking it all up in the engine bay; easier to experiment with the wiring and you can leave the car off and just blow into the sensor's vac hose to test.
ROFL!!! Damn that guy cracked me up... I actually got a bit depressed when I saw his car for sale. :nono:
It all looks pretty good so far, when you coming over to build my new setup? That bottle neck is nuts... I wonder how many there are throughout the rest of the system.
Where is the air for the idle speed control valve coming from?
EDIT: The reason I ask is because the GE's ISC has to pull air from behind the AFM in order to move the vane far enough to close the FC switch. The FC switch cuts power to the fuel pump when the vane is closed.
The resonator? Better to keep it... the difference isn't HUGE, but it does actually help. Search helmholtz resonator... this topic's been beat to death, you should find plenty including links to some dyno experimentation and acoustic analysis which shows how it helps and why.
For a few minutes it had my vote for the humor section. :biglaugh:
Booooo Clip! Premade angles are cheating! I was REALLY looking forward to this. :(
j/k... well, sort of. I'm eager to see how this turns out.
The ECU still measures the quantity of air entering the engine at WOT... you may run rich but it's not going to try to dump in the same amount of fuel it'd give with 6psi of boost.
zy, is your stock O2 sensor plugged in? What you're describing sounds like the TCCS' behavior when it isn't connected. (stays at around 0v, goes up to around 2 when the TCCS adds a bunch more fuel due to some error or odd calculation... does this after warm starts too as a couple MAFT Pro users...
