Description
This fully potted, weatherproof module can be wired into the power supply of a coil per cylinder ignition system, where it senses current and creates a conventional 12V square wave signal output which can be utilized by AutoMeter tachometers and many aftermarket RPM activated devices. Ideal for vehicles with late model engine swaps and applications where conventional tachometer signals are not available.

Questions

Does this increase or decrease voltage signal to the tachometer, I'm trying to get a Proform tachometer to work with the Holley Strip Annihilator ignition.

Asked by: William P
Thank you for your question. It does not do either of those things. This unit taps into the positive wire going to the coils/coil packs. Each time a coil fires, it draws voltage which passes through this unit on the way to the coil. Every time the unit sees that voltage pass through, it sends a 12v square wave signal to the tachometer.

I have a GM stand alone transmission controller for the 4l80e transmission and the GM heavy duty capacitive discharge ignition system . Can I use the 9117 as a rpm input for the transmission controller??

Asked by: bri496
Thank you for your question. No, unfortunately, the transmission controller is looking for a sine wave signal and the 9117 produces a square wave signal.

In a GM LS application, how far away from the coils can I mount the control box? I'd like to place the box inside the vehicle cabin and run wires to the engine coils.

Asked by: mdstitt
Thank you for your question. The module comes with 2ft leads, but you can certainly solder on additional length of 18gauge wire to mount the unit further away from the coils.

Can it be used on RX8 rotative engine ?

Asked by: GTRX
Thank you for your question. When it comes to tach signal and compatibility with the 9117 adapter, the engine does not matter, only the ignition system.

After installing this unit on a 2002 Mustang GT I am getting feedback noise thru the radio if I unhook it the problem disappears, is there something available to eliminate this issue?

Asked by: TDS1
Thank you for your question. This is a popular product and we have not heard this issue before so I would reroute your wiring. Move your grounds to an engine ground and move the tach adapter wiring away from the radio wiring. That should eliminate the interference.
