Ok went to DYI and it states :

-----------

Recommended tooth size is a rectangle measuring at least 2.5 mm x 6.35 mm, with a 5.0 mm tooth height.

-----------

2.5 mm thick required. Started with 1/8 inch (= 3mm) - 1mm = 2 mm
so not think enough based on the spec hence it may just be contributing to the problem.


I will someday think of something clever to say.

Could narrowing the wheel have had an effect on the signal strength ?


Most certainly, but we didn't narrow the whole wheel.
We only faced it off from the inside to just bigger than the crank pulley. What you see in the picture of the lathe is as far as we went outwards.
So the teeth are the same thickness as they always were.

The wheel and sensor came from the same place (diyautotune.com) so they have tested them.
Matt from DIY (very helpful fella) is going to send me another one.

I might buy a second one as well and fit a plug to it ready to go and leave it in the car just in case.
The downside to using a hall sensor in place of a VR sensor is that it requires external power to operate and contains more parts.
VR sensors generate their own signal just by the metal moving past, so they are very robust.

I could not get the sensor to switch to ground even when putting a big chunk of steel in front of it (pair of pliers), so we think the sensor is faulty.

Here's a shot of my setup for the record.
I will paint the bracket and the toothed wheel black once I'm happy with it all.

Looks great but I do not think that will work with the plate teeth against the harmonic balance as it appears in the photo - as it would influence the sensor pickup. The teeth need free air around them. The OEM version does and so does most setups I have seen. I could be wrong when looking at the photo. In any case for those reading.

OEM Set up


One of many custom setups (like yours).


EDIT: Looks like it is in free air in the second photo. So ignore this post. It must be the sensor. I will go and hide now [and enjoy my extended post count].

Now that I'm waiting on parts and can't get the car running I decided to do something I had been putting off for a long time. I bought a knock sensor module back in May 2014 Laughing
2 years is not bad right?

Considering the upcoming mods, a knock sensor is a good idea, so I installed it today.
I had my battery cable mounted to a spot on the engine that was right up near the combustion chamber of cylinder #1, so I moved the cable to make way for the sensor.
I made up a stud from a 7/16 bolt by grinding it down on one end and cutting an 8mm x 1.25 thread. You can see the sensor circled in the pic below.



Wiring ran into the cabin and the module has been installed behind the dash. The module includes a LED that I have mounted in the top centre of the dash. As well as sending a signal to the ECU to retard the timing, the LED will also flash to let me know the engine is pinging.

I always thought they would not be useful due to false positives or insensitivity. I guess getting the sensor mechanism to work reliably would be to hard for non factory configurations. Hence I am very interested in how this works out.

There is a sensitivity pot inside the box.
I'm interested too.

It's this one: viatrack.ca/
And they state this:

I need know the approximate cylinder bore when ordering (piston diameter). We tune each
KnocksenseMS filter so that it better matches the engine. This need not be
exact because the filter is deliberately broad in order account for the
variance in knock frequency due to dynamic changes in operating conditions.

Bye bye distributor.
Finally actually made some room in the engine bay instead of filling it up.



Edit: forgot to mention that the courier attempted to deliver my new crank sensor today but nobody was home. Hopefully I will be able to pick it up tomorrow after work and maybe I can try getting it going again tomorrow.

Cool. Whats that fitting and hose just before the thermostat housing in the intake for/do?

The one with the red/blue fitting is just a heater hose.
The one behind that, that turns towards the throttle body is idle control.

Thank you Summit... new crank pulley and associated other bits should arrive next week if I'm lucky!



In other news - Still not getting a good signal from the crank sensor yet. Hopefully will get that sorted over the weekend some time.

Quick update... having no luck with this 36-1 wheel and hall sensor. Can't get a reliable signal out of it.
I think I'm going to try a completely different sensor.

I think a Honeywell 1GT101DC or Honeywell GT101 Gear Tooth Sensor is the go.

See this with it at work:
