anybody running a 172 flywheel on standalone

[HAndy]

after finally getting the engine back together, i have now come across another hurdle, the emerald ecu does not seem to like the 172 trigger pattern , i have tried 2 used renault sensors , both will start the engine fine and rev upto 2000rpm then cuts the engine out stone dead, ( crossing wires ) ecu wont register any pick up with wires uncrossed
fitted a ford type sensor (of a running engine) will then run to 4000rpm then loose signal again and fall flat on its arse

has anbody had the same issues with the 172 pattern, running standalone

got a brand new renault sensor coming monday,just in case it is the sensors packing up,


anyone running the emerald system with the same flywheel pattern

I had a weird issue with mine back in the day.

When my 172 engine was running NA I ran a totaly standard 172 flywheel inside a GT gearbox using a 172 pickup sensor and it worked absolutely fine.

When I first turbo'd the engine I machined a 172 flywheel to take my miltiplate clutch. Whilst the flywheel was out I decided to machine the double tooth so it made two single teeth (For some reason the 172 flywheel isn't 60-2 it has a gap then a double tooth?) after doing this mod I just couldnt get a standard pickup sensor to work, bought a new sensor from Reno but the ECU wouldn't pick it up, I even swapped the wires and elongated the holes to move the sensor closer to the flywheel. It would sometimes work but it was intermittent. Eventually i used a seperate trigger wheel.

When I changed the clutch and went for a volvo flywheel and used a ford cosworth sensor and its been fine ever since.

I've ran 2 on omex with the stock sensor tho when they failed I swapped to a ford item
