I can't figure out how to get the stock tach to work. I have the tach out wire from Megas... To the factory tach wire ( Solid white) wire. I also turned the tach out, in megatune on. any ideas?

I'm assuming you built the tach output circuit? Make sure you have the tach output configured right in megatune for how it is wired (ex: circuit connected to js3 on pcb 3.0, tach out js3 in megatune).

I did not build the Tach output. This is a Symtech unit. It was set to js3 in Megatune.

Is the white tach wire still connected to the stock ECU?

Dash us off an email at support@symtechlabs.com so we can discuss the particulars of your order. The tachometer output wouldn't be installed on JS3 if your Megasquirt ECU uses a MS-II processor.
