Work in progress

G60 (code PG) engine came equipped with Digifant engine management. This is all electornic and can also be reprogrammed with custom chips which can be even found from Ebay (I dont recommend). But same time this ecu also show some age, with only narrow-band oxygen sensor, distributor etc. Since its all digital, convertion to aftermarket ECU is “relatively easy”. I have run G60 with Megasquirt and now later making new build based on MaxxEcu. Here are some notes, I'ven taken.

G60 has Hall sensor inside distributor. There is 3-wire connector. Pinout

1. Ground (ECU)
2. Signal (ECU)
3. +12V (ECU)

It works also with +5V. You can get motor running with this, though its not very precise.

For upgrade you can look trigger wheel found from newer VW:s part number 036105189C . This is 60-2 sensor found in many later VW engines and is actually backwards compatible. It installs as crankshaft seal undel flywheel, so it is a lot work to install since you have to remove gearbox and clutch. Triggerwheel is just pressed on crankshaft so its bit tricky. One bolt hole is misaligned, I drilled and tapped new hole though it probably would be fine without it.

For this triggerwheel I have Hall sensor, partnumber 030957147 (X). In my understanding VR sensor should also exists but I have no number for that.Clutch housing has small steelplate covering hole behing engine block, this needs small cut for the sensor wire.
