anybody used the bmn nitrous controller?? it has an option for a first gear lockout so that you can avoid the overpowered rear tires during launch.

my question is how does it do this for a 6-spd?? it would make sense that the car's computer for an automatic would provide a signal of when to shift to 2nd, and the controller might be able to read this as the controller is fairly sophisticated and is programmed with a laptop. but where would the controller get a signal if manual trans??

 

i think i found it, uses a dip in the tach signal, like when second is engaged...

 

i believe you are right - it sees the dip in rpms

 

Correct. It reads RPM. When the RPM drops for teh gear shift it counts that as a gear change.

If you are looking for one we have them on sale right now for 99.99.
