OSS with Link Extreme

My transmission has an output shaft speed sensor built into the case that I want to utilize. Not specifically to indicate speed for driving but to activate an output at a consistent time based on speed. The sensor is a 2 wire VR. 

I am using DI2, RR Speed, no pullup and falling to start unless suggested otherwise. Correct?

The other question is, what does the second sensor wire hook to? Sensor ground or a 5v ref? I have only used VR sensors for ignition that specifically have pins for both wires so I want to make sure I don't cause any ecu issues by hooking it up incorrectly. 

Thanks for the help.

Yep that would be the set up to go with. The second wire connects to sensor ground.

Thanks Simon, 

 

Now the second part of the question. I am setting up for a roll race this weekend. I want to setup a pushbutton speed limiter of 60mph and at the same time create an anti-lag. 

Transmission is an auto and I am turbo charged and using dbw. What is the best way to accomplish this? Huge timing retard with the speed limiter?

Yes, the speed limiter will be the best option I think if you know the "roll speed" before the event.  The "rolling antilag" feature (latched launch mode) uses RPM rather than speed so may not work too well with a auto trans.

Set speed limit to ign cut, turn advanced mode on, and experiment with limit ign trim and the control range.  Make the exit decay rate something like 20%.
