36-1 definitely the best solution.
There is certainly no distributor signal, that was purely there to distribute the sparks. It was running before like this on the Weber Alpha ecu on the standard crank signal and no cam or dizzy sensor.

I havn't noticed any OE cam sensor but its possible that there once was one and its been blanked off, will check tomorrow out of curiosity.

The 36-1 trigger wheel should arrive tomorrow which will need machining out to go on my alloy boss which I've fitted on the front pulley.

I will turn the engine to 90 degrees BTDC (ie all pistons level, halfway up) and position the centre of the crank sensor against the trailing edge of the first tooth after the gap and put 90 degrees in sensor position setting. I think that's right?

Making the crank sensor bracket will be the next major challenge, it looks awkward!

Perhaps may be a cam sensor ? Although it's a Megane.

Yes, it looks like it is possibly the case but the Weber Alpha certainly didnt use it!

Unless maybe some later cars used it or something ?

I had a good luck around the engine just now and cant find any sign of a blanked off cam sensor, maybe on later engines?

I finally got the crank sensor bracket engineered ! quite a messy awkward job but got there in the end:

sorry its a bit blurry!

Just got to drill and tap the holes to attach the trigger wheel now, Ive aligned it such that with the engine at 90deg BTDC (all pistons level) the trailing edge of the first tooth after the gap is in line with the centre of the crank sensor.

should be able to get it running now hopefully!

Peugeot and their M7 screws!

Looks like a neat job Martin.
Glad it worked.

It took a lot of thinking about how to make the sensor bracket but it worked out very well in the end.

Its hard pass to on 1/2 a days engineering time/labour to the customer for what looks like just a simple bracket!
