I'm testing the rev-limit, it's work fine....

I have a problem to conecting the tacho, I have a universal tacho, (+) postive, (-)negative, (signal) to dizzy, I conect the wire signal to the EDIS module isn't work, late I conect to the MJLJ is not work.

I conect direct to here (MJLJ) and the pin 11 to EDIS, Which is my problem??

There are a few options for interfacing your tachometer. See here:

Try the diode circuit, or try using the PIP output (EDIS pin 1) to drive your tach.
