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, and the mounting bracket. You won't need to go searching for anything else. Attached image(s) ![]() |

Why would you want a cam sensor? You will find no appreciable benefit to going with sequential injection, so you're talking about adding complexity for zero benefit. (IMG:style_emoticons/default/confused24.gif)
QUOTE With TDC of the crank being for 2 of the cylinders, how do you know which cylinder to fire? As Dave mentioned, batch fire injectors and wasted spark systems fire fuel and/or spark every crank revolution. That's why it's called wasted spark, one of the spark events is worthless. This is an absolutely common way to run your fuel injection. It makes things much much more simple and has no real benefit on anything less than a 'bleeding edge' motor.This system uses a VR sensor, not a Hall Sensor. SDS requires the use of a Hall Sensor, so this system will not work with SDS. Here is a detail of the sensor mount. Attached image(s) ![]() |

Looks like the center hub is about the same thickness as the stock washer, right? That is great! That means you are not adversely affecting you cooling system. How is the toothed ring affixed to the hub. Press fit? Welded?
Looks like great workmanship. |
