Microtech lt9 and tachometer issues
 
Hi
I recently changed from apexi to a microtech lt9 due to limited tuner competence with apexi here in South Africa. After hooking up the lt9c the tachometer no longer works.
Has anyone had this problem before and know how to solve it?

Thanks
Greg

And use the LT9 tach output.

I was informed that you cant collect a signal from any of the coils because of the "wasted spark" signal :scratch: if this yellow/blue is sourced from their then i dont think it will work.

2 sources have indicated you have to pull out the dash and connect to the back of the instrument cluster. however looking at the wiring diagram in the manual, there is clearly a yellow/blue wire in one of the connector boxes, so maybe its worth a try?
