Why do I need a diesel tachometer?
Range: 4,000 RPM range is perfect for most ranges of diesel engines. if a custom range is required, yes we can do that at additional charge
Input: Our special input for a diesel has low voltage filtering to pick up just about any low-energy signal.
User-select able programming: The input pulse setting can be set on site from 2-300 PPR (pulses per revolution)
Glow plug indicator: Standard
Where do I pick up my diesel tach signal?
GM Duramax: Exactly the same as an LS engine from the PCM, check out our tech blog on this subject HERE>
Most other engines without a PCM:
Crank sensor: Usually on the back of the block, this counts the number of teeth on the flywheel, this is the most reliable and easy to adapt if no other sensor is available. Its basically a speed sender for your engine. There are also instances where the sensor is on the front of the engine and picks up on a toothed wheel behind the crank pulley.
Cam sensor: Typically on the front or back of the head.
"W" terminal on the alternator
Injector pump: Sometimes the pump will have a signal out or you can piggyback from one of the trigger wires.
Which kits qualify for a free diesel tach upgrade?
Any 6 gauge Direct Drive package in the Aviator, Performance II or Performance Series (for now)
