Crank Position Sensor, for stock cooling engines Options

[McMark]

Since quite a few people were interested in crank fire and aftermarket FI system I finally finished up my crank position sensor setup. So if you want to run distributor-less ignition or modern FI, this setup is the ONLY setup built specifically to bolt onto a Type 4.

It's a complete bolt on upgrade, which means no drilling or modifying any parts to make this work. Only the cooling fan needs to be removed to complete the installation.

This setup is great for modern FI system, which need a 'trigger signal'. Fuel only setups usually get their signal from the coil firing, but that signal is DIRTY and unreliable. This crank fire setup is smooth and clean. You can't beat it.

There is no other setup built specifically for our motors. Quick easy installation with no headaches.

Complete package price is $175 and includes the trigger wheel, the sensor w/ connector (pigtail or uncrimped), and the mounting bracket. You won't need to go searching for anything else.

Okay, finally had a few minutes to try all this out. I still have to make a final sensor to pulley clearance check once the new batch of sensors comes in later today. But it looks like this will all work.

This is stock DTM for reference.



Here is the trigger wheel installed just behind the unmodified DTM crank pulley.


This pushes the unmodified crank pulley out ~2.5mm, so a simple washer is installed behind the alternator pulley to space it out ~2.5mm.


Here is the overview of the whole setup installed. Belt geometry is unchanged.


I'll make a final check this afternoon and confirm that the sensor doesn't foul the crank pulley.

Great! Nice, simple solution, just what I was expecting from McMark! (IMG:style_emoticons/default/pray.gif)
I had visions of spacing the entire fan out, nice to see THAT is not necessary!

Thanks.
