Tach Connection

Lucas-

One more question from my Precision Eagle EMS connections. The system has both Tach and Fuel flow parameters coming from the engine computer. They describe the leads as follows;

The RPM signal is 2 pulses per revolution occurring at 0 and 180 degrees and lasting for 30 degrees of crank rotation. 30 degrees translates to 2.4ms at 2000 rpm. The fuel flow signal pulse duration is 1.6ms (20 degrees) at 2000 rpm and distributed over a one second time period. Fuel Flow default is K factor = 32,000.

Does this sound like it will work with the EDM system? Once again, thanks for your help.

Hi Peter,

No problem. The pulses per rev are adjustable in the EMS setup as is the K-factor. Our K-factor will go from ~10,000 up to ~120,000 (don't remember the exact numbers :) ). Thanks!

Great. That is just the answer I was looking for.
