Since you use the same clutch switch for both launch and FTS, do you also use the same ECU pin for both, ie. B5? Is B5 supplying a +12V to the switch? When the switch is grounded, what happens to the Air Conditioning Switch? Is it affected? Trying to understand changes inside ECU and programing.

You will be best off using the same input for both. It would be much harder to use 2 switches and 2 inputs.

Any input you use will can no longer be used for it's original function.

OK, So any pin used no longer has its original function. I quess the pin options that you can select in S300 are not needed by the original ECU setup anymore, like the brake switch (D2)? Sorry for the questions but New to Hondata.

They are all the inputs that can be used. It is up to you which one you use. Whatever input you use, it will no longer be used for its original purpose. If you don't want to loose that function, then choose a different input.

Thanks for the help!

let me ask you this what is the best way to set up the launch control meaning hardware wise?

Since I have a complete MSD ignition and distributor setup, I plan on using the MSD 2step for launch. That way I can use the ECU pins for other functions that I want.
