Hi All
Anybody fitted one of these and care to share your know how and tips to fitting and setting it up? Routing wires, module placement etc.
I started last year but time got taken up with other things and is now in limbo.
Cheers
Dave
 
Fitting the kit is a doddle, put the module on the side of the engine bay near the distributor and you'll not have any trouble.

The biggest problem you face is timing the distributor up again, you have to get it just right or it won't start and the old method of static timing with points obviously no longer works.
 
Thanks for the reply Jimbro

I went and had a look at where I was upto last night and here is where I am at. See pics

I had no idea of where I was upto. The replacement distributor internals are in - that chopper device can only fit on the distributor cam one way right? - and I have temporary place for the module. I 'think' my reasoning was that I just wanted to be able to get it started and set up before deciding on a permanent place for it.

What happens to the green wire (LT?) that was connected to the side of the distributor?

You mentioned that getting the distributor timing right or else it wont start, I think you can guess my next question. How do I go about setting it and what do you do in place of the old static timing?

Thanks in advance

Dave

Static timing requires a little inventiveness, instead of watching for a spark you need to create a temporary circuit with a low wattage bulb between the coil -ve and ground or use a voltmeter to measure the PD across the same.

When the bulb is lit or the voltmeter reads 12v the circuit is open and you would be triggering a spark.

With this in mind you can basically follow the normal static timing setup: (taken from the lumenition fitting guide)

Turn engine and align timing marks making sure the rotor tip is pointing to the HT pick-up segment in the distributor cap of the recommended firing plug, normally No 1. With distributor cap removed the leading edge of the chopper blade should be 2/3rds across the lensed units in the direction of rotation.

Slacken distributor clamp bolt and very slightly turn distributor in direction of rotor rotation. This is just enough to bring the chopper blade before the point of passing between the lensed units. Switch on ignition taking care not to crank the engine. Very gently return the distributor against the direction of rotation to the exact point that the voltmeter reads around 12V or the test bulb lights. If you overshoot return far enough to start again otherwise you will time on backlash.


Just remember that the X1/9 times from cylinder #4 not cylinder #1. The correct timing marks are on the back of the timing belt cover (the metal plate) and cam pulley. The best place for timing the crank is from the flywheel but failing that the pulley wheel does have a decent timing mark on it.

As for the green wire - I thought that was for the old condensor which you no longer have a need for. There certainly isn't anything I remember in the lumenition kit that relates to a green wire.

From memory you have a bundle of three wires to/from the distributor and the PDA50 module. You also have three wires to/from the module for power (red), earth (black) and coil -ve (brown). Everything else should be redundant.
 
Thanks Jimbro

Apologies in advance if this is a dumb question.

When it says 'Turn engine...' how is this done?

Thanks again

Dave
 
The easiest and simplest way to turn the engine is to use a big wrench on the crankshaft pulley nut. You'll need to take the o/s/r wheel off in order to get to it but beyond that it is pretty easy to get at.

The alternative is to rock the car forward and backwards while in gear but this isn't a particularly accurate way of moving the crank!
 
Cheers Jimbro

I feel like I am able to get somewhere now. Do you know what size wrench is needed? Sorry for all the questions :eek:
My Dad being an engineer has lots of large spanners etc so I'll be able to borrow one before I start and find all mine are too small.

Your help is much appreciated

Dave
 
Well after I had got it set properly, she fired first time and without hesitation. Passed the MOT the following day.
Thanks again guys.
