20v into Cab

[Tonks4x4]

No not the S2 lump unfortunatly after 4 months with out my car Please help

We have managed to fit the 2.3 20 Valve engine and gearbox into the 1994 Cabriolet. We have managed to overcome all of the mechanical problems related to this. However we now have one last electrical problem we need help with.

The ignition firing point sender is showing a fault on diagnostics. We have changed the sender, Made sure it has the correct air gap for all the different types of settings shown. Every other bit of electrics checks out perfect.

So we need to know if anyone out there can tell us what information the firing point sender actually sends to the corrosponding pin in the ECU. If we can supply a trick feed to the ECU we can do away with the sender as it is a none changing reading once the engine is running apperently.

Does the sender run off the flywheel by any chance??? If it does is the pin on the flywheel still intact???

Yes it runs off the flywheel side by side with the flywheel sensor. One picks up on the ring gear and one picks up on the pin located in the flywheel that has a strange setting of 15° before or after TDC on cylinder 4. The pin is intact. But we can not find a completely definitave setting for the air gap as there is quite a few settings in different manuals.

sounds like a very similar setup to the aan engine, no mention of air gap in the bentley for that just bolts in, there is however a test you can do with a multi meter on the pins of the sender i think it's 1000 ohms accross pins 1 and 2 and open accross 2 and 3. I have a failing engine speed sensor which throws an implausable signal code when on vag com, from memory if one of the senders fails whilst the car is running it reverts to using the signal from the other (aan yours maybe different)
