BS3 tach output to Ultradash

[Scott B]

Anyone know how to get the Ultradash to read the tach output from the BS3 box. The Ultradash I have is not the one that connects directly to BS3.

The BS has a tach output, the Ultradash has a place for it, but my dash is not reading it.

Thanks

The Tach output on the BS3 is designed for an LS1 application. If your ECU is not configured for an LS1 this output is not populated. This signal is also a different signal then a normal square wave Tach output.

The BS3 is only designed to communicate with a Race-Pak and/or UltraDash through the Can Bus V-Net output. If your BS3 is not optioned with this output, you should send it back and have it installed.
