Hello i have sp1000 and havent Been able to activate my launch control. I have no vss input and think that's my problem. We're is easiest place to get a signal?
Is a vss signal necessary as cur switch or can I use another parameter? Stuck on this for days, any ideas thanks

Not using a VSS as an input you don't have a way of activating it. The factory VSS is pin 18 I believe on the stock harness. Also having a clutch switch would be helpful too.

Thanks the clutch switch is. I will look for pin 18, I also found that pin 11 on diagnostic port might be a signal. Will check later. Thanks
