Does the XFi system have a 2-step integrated into the main ECM? I already have a Harlan 2-step, but would prefer not to have any extra boxes/wires to get a 2-step on the car.

yes it does. it is labeled as a clutch switch. i will see if i can find what pin it is.

that is what i used

gray 32-pin conector

number 20 i believe. look at your schematic to be sure.

all you have to do is ground it using a momentary switch of your choice

In case you haven't found where you set it, that is located under Spark Functions, then Sequential Rev Limiting. I've used it for burn out control.

Install a wire into slot A20 and make sure you check off the "Clutch activation" box under "spark functions" - "sequential rev limiting"
As said you are required to ground this wire to activate it.

If you dont have any pins I can set you up with a pig tail with one on the end.

Ed/Otto/Greg,

Thanks for the informative response! I have another question:

Is it possible to set (2) two step's? My thoughts are to bring it up on the first stage in pre stage, and then when i hit stage, be able to activate a higher two-step. I hope this makes some sense. I have heard of this being possible on some system, but wasn't sure if it was the XFi unit that can control this.

Thanks!
Tim

The XFI only has a single 2 step.If your ignition system has one you can use both,hook one to the footbrake.
Instead of doing this on our bigger turbo cars to help spoolup we installed a second caliper on the rear brakes.This allows your to build big boost on the brakes and even control rolling into the lights with control.
If you are using a transbrake I have used the transbrake creep,it really work incredible when setup properly.

There are enough unused wires, I just move one I don't need. One for a Ford, Hemi, etc. I have removed several unused wires from my harness.

Make it even easier and go to your Powerad connector,hook into the pink wire (pin E)
to your switch and click the button under "sequential revlimiting" for "PA hold Activation"
make sure you don't have any Nitrous functions enabled and your all set.
Unless your using nitrous than this will keep the nitrous off while on the 2 step anyway.
Just be sure the "pa force max stage" box isnt checked.
