can someone tell me how to set up the 2step rev limiter?


what settings do i put in , if i want it to rev to 5k?

i seen there is a mph, vss, rpm fuel cut, rpm ignition cut, etc



thanks!!!!!!!!

 

Try 10/ hard cut in params. Then options. ign cut 5000. Fuel cut 6000. If you want to build a few pounds of boost use the ign retard. Start at like 4950. The lower you go with this rpm the more boost you will build. Vss 10. The launch control will work under this mph.

 

Do you have to wire some sorta switch to make the launch control work? Or is there another way without installing or wiring something?

 

If you use the vss in the 2 step setup there is no need to wire anything. If you want a no lift to shift setup, you will need to run a wire from the clutch switch.

 

ok i just tried what you said:

getting tons of backfires, and it didnt really build boost... is that normal?

what do i set it to? Always ON? VSS? theres about 15 to choose from.

 

Always on.!!
The vehicle speed sensor is what your using to activate launch control. Under 10mph it activates. If you want more boost lower the retard rev rpm's in50 rpm increments. Test, and adjust to your setup.

For my 35r setup i was doing ign cut 6000, fuel cut 7000, retard rev 5750. That got me around 10- 14 psi off the line.

 

ok .. i think that i didnt put on the hard cut.

 

on mine all of the rpm's for all the options cut out at 6000

 

Yea I am running E85.

As far as the switch setting goes, as mentioned above set it to always on and use the speed sensor to activate it. I am running 10/ hard cut on both my main and 2 step limiters.

Fuel cut 1k higher than ignition cut = backfires like crazy, worried about fouling plugs.

Fuel cut 1k higher than ignition cut, but only part throttle = no backfires and A/F around cruising range, which for me on E85 is 15.7-16:1 ish. (this is what I chose to leave it on).

Fuel cut same rpm as ignition cut = no backfires, but running lean on the 2 step which makes sense. I am not sure if this is bad or not since their really isn't much load to speak of, so I chose the above option for safety reasons.

Tried anti lag once, but I don't like the idea of extra fuel exploding inside my turbine housing. My clutch slipping seems to build boost just as well, although probably not as fast. I will just have to settle for 1.7 60's at best

 

yes
