MJLJ questions for PioneerX
Hi PioneerX,
I've got some VX MJLJ related questions to ask you!
How did you fit your trigger wheel to the front pulley? I've had a look on your website but it's not clear from the pictures.
Also, how and where did you mount the VR sensor? Ditto the pitures on the website.
Did you use vacuum advance?
Also, have you got any more information on your keyless ignition switch? I wanted to do that!
Cheers
Graham

Northy,
Yep, I know the website pictures are not great for the installation of the tigger wheel and sensor, mainly due to the restricted space and the fact
that ALL my parts are black.
First off. The trigger wheel. I want to mount the trigger wheel in such a way that I could still remove the pully, but mounting on the back was no an
option as it moved the pully out by 5mm and screws up the belt alightments. So What I did was........Removed the pully Drilled and tapped two M6 holes
in the center hub in-between the mounting bolts. I drilled two corresponding holds in the trigger wheel to allow two long M6 bolts to run from the
trigger wheel to the center hub, through the open space in the hub. Now heres the key, the vauxhall front pully is actaully two sections (the hub and
the pully grooves), these two sections are held together my a rubber interface. The interface helps to absorb shocks to the belts, but it is raised
above the surface of the assembly by 0.5-1mm. The exposed rubber interface helps stop any movement in the trigger disk due to the long bolts. Once
tightened but the trigger disk and center hub become locked with almost no effect on the rubber interface between the center hub and pully grooves.
As for the VR sensor. My mounting brakets is a plate attached behind the altenator bracket, this plate has an arm that comes out and down to the the
trigger wheel.
Yes I have vacuum advance. The dellorto carbs have a vacuum take off on carb1, it sticks out at 45Deg at the very front of the carb. Fortunatly the
maifold I have has the servo tak-off on port4. The tread for the servo take off is an ideal fit for the vacuum take off from the mondeo manifold. So I
used ports 1 (from the carb) & port 4 (from the servo connection), these are at opersite ends of the cycle and therfore can be tee'd together
producing a relativly smooth signal, but this is run through a anti-pulse valve from the same mondeo and the resulting signal does not show every much
of the pulsing effect you get from attaching direct to only one branch.
Keyless ignition switch. This is a custom made unit, based on a motorcycle immoliser unit. The system has two dash switches and a wireless
transponder. The first switch turns power on the the imobliser unit. Motor Cycle one was used as it does not require power all the time. Whent he unit
powers up with the first button, it is imoblised and the lights in the buttons done work. Then the impoliser detects the trasnponder it switches a
relay pack, this turns power to the fuse box, power to the button lights so you know the transponder has been picked up. The second button on the dash
atives a relay for the starter, the power is passed through the start button & the relay pack to the starter relay. Basically all this means that
to turn the cars electrica on you need to push the button with the car on it and have the transponder on you. The button then light up blue and
eveything is working. To start you must push the start button, but this will only work is the light is on (ie the transponder has been found). To turn
off the whole system simply press the car button again, the blue lights go off the relay pack goes off and the imoboliser arms again. I do have a
circuit diagram but not with me right now.

Some of the Westfield guys are just machining the back flange of the bottom pulley to be used as the trigger pattern

Yep, that would work well as there is enough material at the back of the pully to do that. To be honist I didnt think of that when I did mine.

Can't you configure the ecu to run from the standard vauxhall internal trigger wheel and std Sensor?(assuming you have a 2ltr!)??

NS Dev,
Your right, and even the 1.8 I'm using has an internal trigger, however if memory serves (as I dont have the reference to hand) it's a
62-2 trigger. Strickly speaking the MegaJolt is not the problem, the VR sensor does not feed into the MegaJolt it feeds to the EDIS module, the EDIS
then 'requests' the current ignition timing from the MegaJolt on the PIP line and recieved a single on the SAW line that corresponds to
the correct advance. Beacuse of this it's the EDIS that does the sync to the tooth signal not the MegaJolt.
Bottom line: To use the Vauxhall trigger wheel would require using something other than the EDIS module and re programming the MJLJ to give the
relevent signal to this 'other' module.
Seemed easier just to mount a trigger wheel

PioneerX is right. The standard Vx is a 62-2 trigger and so won't work with Ford EDIS, it might with another though. If anyone knows which
thatwould be a bonus!

I don't know about the rest of this stuff, but I'd REALLY like to know how you've set up the bike immobiliser.
(Perhaps we can break out of this topic and start a new one in Electrics)
Cheers,
David

David,
I will hunt out my wiring diagram for it and start a new topic in electrics (if no-one has yet ,as I have not get down that far)
Might take me a day or two to find iit though. I will see if I can get some pictures uploaded of it installed as well as I do have it and working.

PioneerX,
Cheers for the replies about the front pulley. I don't think mine has any rubber on it though!  Tax runs out at the end of the month so
I'll take it off and try and fit my trigger wheel.
What is your triger wheel from? Did you make it? I've got the one from a CVH Sierra from pulley.
Come on, find those ignition details, we're all waiting!
Cheers

Well, I don't really know, but the vauxhall system is run dizzyless, but then I think all the ignition is controlled from within the ECU,
certainly the crank sensor feeds into the ECU directly.

Taken from Retro Cars mag-"You should also get a Sierra crank pulley which will provide the trigger wheel-or if your after a pressed steel wheel
try Ford-£12-part number-1078767"

Theres a photo of my crank pulley fitted with a sierra toothed wheel, in the posting alloy crank pulley for a crossflow.
I have spent today making the sensor bracket and now have that fitted also , i used the sierra sensor.
