Turned the idle control on.

Same thing. When I turn the AC on, the car dies in short order.

Even light pressure on the accelerator doesn't seem to help much. Car braps along at 1600 until AC is on and even if I give it gas with the pedal, car loses the brap and sounds like it's being strangled to death.

All I can figure is AC throws me into some untuned cells?

With AC should I throw more fuel at it in the map?

Is the bridgeport really that gutless at idle that it can't run AC well?

 

i tinkered with it some more today got it settled to about 1550... but it i rev it goes up to 1800-2000 for a few seconds then eventually comes back down..

my tps is in spec expect for the wide? (bottom wire) only reads like 2.34ish at WOT... if ignore everything else, the highest i could get it to is 3.5x... is this okay? i tried 2 tps so i doubt its a bad tps.

im starting to tune fuel myself too... so just curious about a few of other peoples settings...

idk if this is relevant but my fast idle cam screw is also tied back, could that be my issue?

 

bump, anyone?

 

Do you have a datalogit?
Turn the idle down to 0
Turn 02 feed back off.
Unclick the timing idle control,
Turn you throttle linkage screw all the way out and just turn the throttle adjustment screw on the bottom on the throttle body.

 

=( no datalogit yet...

can anyone with a HBP post what afr, rpms and vacuum reading you have at idle?

 

i recently did a hbp and my car idles at 3000rpm....anything less and it dies....My tuner was able to get it to idle at 1800rpm but that didnt last long....its back to 3000rpm....the idle sometimes sticks at 3000-3400 while i drive the car.....do i need to run in the engine some more for the idle to settle?

 

Find another tuner. A half-bridge can idle at 1,200 RPM if you have an idle controller or 1,500 RPM without.
