Stock tach in AW11 with mulitcoil 4agze

defcon · 04-22-2009, 01:24 PM

Is there any way to wire up my original rpm tach to the 4agze's 4coil igniton setup. My 4agze is running Autronic ECU.

Thanks

MSnS-Extra Hardware Manual

Drop down to "Another option for Hi Voltage output to a rev counter (rev counters that were fed from the coils -ve)" and build that circuit. Put that between the coils and the IG- wire on the diagnostic connector, which previously went to the negative side of the coil. Should work like magic...
