Dave Kriedeman Posted June 18, 2014 Report Share Posted June 18, 2014 Hi turbodude, There are many ways to activate the launch control via speed. It is dependant on how many digital inputs etc you have spare. But to keep it simple, Activate launch control under Motorsports Tab. Select MODE 1 2D option under Launch Mode. Select an activation method, easiest would be the DI that the Vehicle speed is connected to, however I would advise wiring a separate DI switch to activate Launch Control, unless this is a drag car. You don't want launch control to activate all the time if this is a street going car. I have attached a basic setup screen shot for you. All your other setup values you will need to set to suit your desired requirements. Regards Dave. Quote Link to comment Share on other sites More sharing options...
turbodude Posted June 18, 2014 Author Report Share Posted June 18, 2014 Ok I have the expansion harness. Its my play car but I see what your saying. How would I wire one of those spare digital inputs to my clutch pedal switch? Thank you. Quote Link to comment Share on other sites More sharing options...
Dave Kriedeman Posted June 18, 2014 Report Share Posted June 18, 2014 Hi, firstly you need to establish if the clutch switch is negative or positive input. Test with a multi meter and let me know. Regards Dave. Quote Link to comment Share on other sites More sharing options...
turbodude Posted June 18, 2014 Author Report Share Posted June 18, 2014 its positive input, it complete the circuit for the starter. Quote Link to comment Share on other sites More sharing options...
Dave Kriedeman Posted June 18, 2014 Report Share Posted June 18, 2014 Hi turbodude, What digital inputs do you have spare or do you wish to use the clutch switch. If you wish to use the clutch switch then you will need to setup the DI as follows which if already running you should have done. FUNCTION - GP INPUT SWITCH TYPE - MOMENTRY PULL UP RESISTOR - OFF ON LEVEL - HIGH ACTIVE EDGE - RISING. Regards Dave. Quote Link to comment Share on other sites More sharing options...
turbodude Posted June 19, 2014 Author Report Share Posted June 19, 2014 after further investigation, the mr2 has two switches, one at the top of the pedal and one on the bottom, im going to use the bottom, it uses a ground to turn on and off the cruise control. i prefer this because i normally launch the car at the bite point of the clutch rather than the floor. IS it the same procedure? Figured i would just cut the switch, ground one side, and then run a wire back to the Cipec expansion harness to DI4. Would this work?

Dave Kriedeman Posted June 19, 2014 Report Share Posted June 19, 2014 Hi, yes that is OK, just use the first setup example I showed you for the DI setup, using negative or low switching. Try changing the switch type between toggle and momentary, but it shouldn't really matter. Regards Dave. Quote Link to comment Share on other sites More sharing options...
