Just make your own hose with a pair of self assembly banjo fittings and some braided hose.

Just looking at you pics of the engibe install and cant wait to see the real thing

I,m just making the bracket for the sensor for Megajolt and Im easily confused about this, Andy.

Do I need to put the sensor exactly 90 degrees before TDC and if so, where on the sensor and trigger wheel do I establish the point which should be 90 degrees before ?.

OK got it - just put the sensor exactly at 90 degrees with the missing tooth gap centred at TDC -right ?

Yes

This is a worthy read if your starting out.

If something is worth doing, it's worth doing half of.

It might be the picture but that sensor looks in the wrong place to me.

It does to me too tom but I haven't been through to look yet.

Looks about one tooth out to me in the picture, although the angle of the VR sensor is a bit deceptive in the photo.

It's got thirty degrees more to go (= 3 teeth) before TDC and the sensor is 7 teeth behind the missing one so total 10, not 9 IMHO.

I think you can adjust 10 degrees though in MJ (you certainly can in Megasquirt).

EDIT - looking good otherwise, you're outpacing me now......

I never said the engine was sat at TDC .

If you have set it by aligning the missing tooth to the marker on the timing cover, and then placing the sensor 90 deg anti clockwise, then it is in the wrong place. Is it the pulley Phil machined for you?

The missing tooth is vertical at TDC like the pulley you supplied me Tom.

I believe Andy ordered the sensor bracket to position the sensor 90 deg anti clockwise from there but as I say I haven't seen it yet.

Thanks for everybodies comments/concerns, but as John says the missing tooth is at the top of the pulley with the engine at TDC. The CPS sits on the horizonal plane accross the centre of the pulley, making it at 90 degrees. It's not very clear from the pictures as I had the camera at a funny angle, but it is in the right spot with a small tolerance in either direction. I was very carefull to check it before I finally fitted it.

You all have the right to say 'I told you so' when we can't get it running on megajolt and/or we kill the engine from too much advance

by my deduction the sensor is pointing at 100* BTDC

Reading all this with interest - I have made the bracket adjustable and also have up to 10 degrees of adjustment on the trigger wheel where it is attached to the damper(always was a belt and braces man)

The only problem with that logic Colin is that the sensor is actually pointed at the one you marked up as 90. Like I said funny camera angle. Will get another pic in a little while.

Well OK then

You do realise that the air gap needs to be 0.5 to 0.8mm and the sensor perpendicular to the target tooth?

Edited by Sprocket on 30th Nov, 2009.

This is all probably due to the camera angle......

I wish I had not posted but it really does look like one tooth (10 degrees) out in the initial photo, so please just check it before you run it....

(and you can kill me later !!!)

Here's a better picture. The screw driver is sat in the cut out at tdc. The sensor is pointing at the 9th tooth down and is very close. It might be a couple of degrees out, but we should be close enough to adjust it in the megajolt software.



While I had the interfooler pipes of, I fitted the new screenwash bottle. It's tight but it fits.



You can see how close the sensor is in this pic. I haven't measured but it looks like less than 1mm to me. I guess only time and the meajolt software will tell if further adjustment is needed.

If the sensor is mounted with an air gap less than 1mm, its still pointing to 100* Unless the camera you have bends light in ways no other camera does, lol

Shoot me anyway, I am told im wrong all the time

I'm with Sprocket still, it's on the 10th tooth (100 degrees) not 90 degrees !!!!

So shoot me twice !!!!!!

Schrödinger's cat - so which one am I ???

Right. I really appreciate that everybody is trying to help out, but...

1) In my picture with the green lines, the camera is tilted backwards so that I can get the whole wheel in. This gives the impression that the sensor is pointing at a different tooth. It's not a very good camera. Because of the metro engine mount I can't take a picture side on as it is where the camera would need to sit.

B) With the greatest respect to everybody that has commented, I can count! I have had my face in the engine bay and counted the teeth, using the fingers on both hands, and the sensor is pointing at 90(ish) degrees. I can get my wife to check for me tomorrow, or use my toes instead of my fingers, but this will not effect the outcome. It is pointing at the 9th tooth after TDC.

iv) Again, the camera angle makes the sensor bracket look miles away from the pulley, but it isn't. As I said, I haven't measured it, but it is less than 1mm.

7) John is coming round tonight to do some work on the van and he will verify, that although I am an idiot, I can count teeth on a pulley...

z) If you are in the area, feel free to call in and have a look, maybe even lend a hand for half an hour. The kettle is always on.
