Launch Control??

[Rumbuck]

Hey guys,

Is there a way to set up Launch Control on a Cable driven Throttle Body?? Or can I just use some form of electric Motor Drive on a standard Cable Throttle Body (Aka conversion) and hook up my Launch Control like that??

its done via a static rev limiter in the ECU..... but isnt your car N/A??

 

[Rumbuck]

Yeah for the moment, looking at Centrifugal Supercharger by converting an AirResearch by Garrett Turbocharger into a Centrifugal with ceramic bearings, though I may simply run oil to it and be done with the idea. Gotta get the turbo and pull it apart first.

what ecu did you end up using?
because it might be a option on it.

it is on my ecmlink, it comes with 3 limiters, launch, no lift to shift and rpm top limit.

 

[Rumbuck]

Yeah, I have RPM Limit, Launch Control, and Flat Shifting.

That said, the way the principle has been described to me is that if I set Launch Control, I will then press my foot flat to the floor, but only get optimum launch revs. With an electronic throttle I can see how this would work by intercepting the signal, but with a cable throttle, I could have my throttle open 100%, but my ECU only delivering say, 50% max fuel...so in effect, I'd badly lean out.

It'll work the sane as your rev limiter just a lower setting. Controlled by ecu. The way I see it, the ecu interrupts timing do it stops firing at certain rpm so it stops climbing.

Rpm limit on advanced ecus will give you an option. You can either:
1. Ignition cut
2. fuel cut
3. Ignition and fuel cut

 

[Rumbuck]

Yeah, mine doesn't have ignition and fuel which is a shame considering it's $2000 of aftermarket ECU :fuuuuu: I have the option of Ignition OR Fuel...so given the choice of Not firing or Leaning out...I'll take not firing personally.

 

[4piknup]

Take the fuel cut or you will fill exhaust with unburnt petrol... Won't run lean as it not putting any fuel in anyway, and won't hurt if it was lean as engine has no load on it

 

[Rumbuck]

Cool, well, I'll do that then
