he explains how this works but i dont understand..getting a strait response form there is hard as hell....im using the innovate wideband and if you know it only reads the A/F ratios onto a laptop..this new device will allow you to read RPMS now...i dont know if it will work on the rotarys ignition.....

 

It will if you use the signal from the trailing coiling, the same one used for the factory tach, black/yellow stripe IIRC. Set it to 4 Cyl, and the RPMS will read true. Although, there is a lead off the leading coil that is for a tach also, don't know if it work though.

im assuming it will, since you can use an aftermarket Tach why not this.

 

good point !!!
i figure for another 100 bucks...why not!! at least now ill be able to log my damn fuel and tach and timing to see where exactly i need to tune the damn thing...
thanks..
