Is your car a 6 speed or auto? The thing that kills the launch with the 6 speed car is that it has a low rpm limit when the car isn't moving so you can't dump the clutch and break anything. That has to be addressed in the ECU unfortunately. I am going to try to come up with something to fool the ECU out of doing this, but I just don't have the time or electronics know how. Any electronics gurus here that can design a simple device based on an idea? If so, contact me- sales@joepmbc.com - I may have an idea to trick it, at least on the 6 speed cars.
