The haltech wont let you run both, which one is better to have hooked up?

Chris

 

which one do you have?

mike

 

both, but which one should i use?

 

Hows this, which did you (anybody) use in your personal Haltech install? Is there a reason why you chose that one?

 

well i used a bac because the thats what the engine comes with. an idle speed motor costs money because you have to buy/find one

 

a turbo TII has one, its on the back off the intake manifold. Unless i'm mistaken

 

I'm trying to run my BAC but am having some troubles setting it up right. I'd like to use it now that it's 45F in the morning. How is yours set up mike? e6k

 

FCs use a BAC valve. I have mine hooked up, but for some reason the Haltech only uses it when it "feels" like it.

 

That's what I'm seeing also. It just decides when/if it wants to use it. I'm sure I just don't have the parameters set up right.

 

There's not really much to setup. Just the idle speed parameters and the period which I read somewhere was best set at 21, but that really only affects response time from what I understand.

It has something to do with my throttle position. Of course it has to be calibrated, mine is, but if I give it just a little throttle (<1%) it'll start working and keep working if I take my foot off. But then if I hit the gas again it'll stop controlling it.

 

i actually have it turned off right now, we couldnt get it to find a stable idle speed. it surged like an fc with a bad tps, and we ran out of time before sevenstock to play with it more.
