This is a typical loom made up, this is for a 205 GTI and will plug straight into the car’s loom.

Note: the length of wire to the crank sensor, this allows plenty of room to hide and tuck away the install.

This is my original timing wheel, to get it all aligned I drilled out the pilot hole to 14mm (the same diameter as the Peugeot crank bolt). Then fitted a steel bar across the sump and mounted a the Crank Sensor on some angle iron. Worked well enough but not the prettiest install.

Now my engine is out and I’ve had the crank damper machined to take a 5.25” trigger wheel with a 4.5” centre hole, this will be much tidier. I plan to get the sensor located in the right place to read off the wheel then, I’ll time up the wheel.

The engine is out of the car, but all coolant piped up, as it always seems to leak water from somewhere, so I’m constantly checking it over for leaks, at the mo found a couple of obvious ones. But the head gasket doens’t appear to be leaking any more, hmmmmmmmmmm.

Here we have a pair of Peugeot Mi16 Crankshaft dampers, both machined to take a 5.25” ring gear trigger wheel.  The crank sensor will be mounted on the sump on an aluminium bracket.  I will install one of the dampers on the crankshaft, and position the sensor in line with the trigger wheel. Before timing it up correctly.

Important the crank sensor can be mounted anywhere with respect to top dead centre. But with the crank at top dead centre on no1 piston, the missing tooth must be 90 degrees ahead of the crank sensor, as you can see from my animation. This allows the EDIS/megajolt time to do it’s bit and sort the spark.  Please click for to see the animation.

The other reason for the change, is my car run’s bike carbs, and they are nicely provided with a throttle position sensor (TPS).  My first Megajolt was a MAP version, but I now have a TPS for it. It has a Bogg Bros manifold and I’ve been using them for my rolling road tuning since 1998, for my GTE 16 Valve elsewhere on this site. I remember in about 2000 they were talking of the bike carb conversion, and there was a cardboard box in the corner next to the rolling road, with loads of various sets of bike carbs, so I bought a few sets, R1’s back then for £10 a set - far cry from today. This was partly due to webers no longer being available - at the time.
