Hello
I have a Lightspeed iginition and a Vans Tachometer. I am not able to use either of the Vans tach drive sender units.
The Lightspeed box outputs 4 10v 3.0ms pulses per RPM and the Vans Tachometer requires 8 pulses per RPM ( requires a 5v to 15v pulse signal).
Consequently my guage runs at exacty half real RPM.
Has anybody created some sort of device that doubles the 4 pulses/RPM to 8 pulses/RPM ....so that the tach reads correctly .....
or.......
does anybody know of any way to modify the internal of the Vans Tach itself to read twice as much as it does currently ?
Any suggestions greatly appreciated
many thanks
Rainer
