Innovate Motorsports MTX-D Boost/Shift gauge
 

I always do a ton of research before I post on here but anyway have had this gauge for awhile just using it to monitor boost. I have recently tried to hook up the shift light and have tried everything and cant get it to work. I have searched the forum for tach wires to hook into (pin #110) and it isnt working. Is there another tach signal wire that someone knows of that will work with this gauge to read the tach?

You will need to set up the resolution on the gauge s well.

Thanks for the reply Jason. I believe that is the same wire as Terminal #110 that I currently have the wire hooked up to. I have the gauge set up as 3 pulses per revolution. I'll double check everything is connected correct but that setup isn't seeming to work for me for some reason.

I don't remember my resolution, but I know I had to play with it to get the RPM to register on the gauge. Let me know how you make out.

So I ensured the connections were solid and still isn't reading my RPM. Ran the red wire from the back of the gauge to Pin 14 and left the ground wire alone as the instructions say. I went through every resolution from 1.5 to 10 and none of them work. The gauge when I turn on the ignition flashes how I have it set up for the shift light but that is all I get. Don't understand why it isn't working. lol Surely it doesn't have something to do with me being 7AT? I have also read a few other places to get the signal like negative lead of injector but didn't want to try it without conformation from someone.
