I have searched all over for a way to have MS2 run my aftermarket tach and window switch for N2O. I have a MS2 V3.0. Seen all kinds of circuits but dont know which one I need to do this. And the ones I have seen dont give very good directions on how to build the circuit. The car has a GM 3400 in it, and the stock ECM is no longer in the car. MS2 runs the entire engine. Any help would be great. Thanks.

Re: tach output for aftermarket tach
You should probably use the stock ignition module - I'm pretty sure that has a tach output on it. Depends on what year 3400 though.
Window switch functions are easy: Just use the Spare Output Ports function and mods.

Re: tach output for aftermarket tach
The engine is from a 00 Grand Am GT. The car its in is a 96 Cavalier. I tried the tach out on the DIS. The tach and Zex window switch both showed false readings compared to my Megatune tach which is right on target. So should I build tacho output with the relay to run these? And if I do build this circuit the only port i have available is J11. What would the port settings be to run the circuit?

Re: tach output for aftermarket tach
Exactly what sort of aftermarket tach is this, and is it still set for the four cylinder engine a 1996 Cavalier would have left the factory with?

Re: tach output for aftermarket tach
Its a Cyberdyne set for 6cyl. the tach and window switch both say to connect to the negative side of the coil.

Re: tach output for aftermarket tach
You may just want to get a DIS tach adapter, like the ones from Auto Meter.
