The test drive was okay but the clutch pedal wasn't releasing the clutch enough so very difficult to change gear. I was a bit suspicious whether as well as upgrading the clutch, flywheel etc. to an M3 it would also be necessary to change the clutch master cylinder. Well that's what I had to do.
Nice new M3 clutch master cylinder. The release stem is longer, haven't tested it yet but hopefully it'll solve the problem.
Idle regulating valve - replaced
ABS sensor. I'll mount this and see if I can get the speed signal from it instead of using the diff sensor.
The front right hub upright already has a hole for an ABS sensor.
Something like this ...
and this ... problem was the hole is a little too small and also slightly in the wrong place, at least for the ABS sensor I bought (M44).
Hole enlarged and fixing hole with M6 thread to the right. Also had to make a slight adjustment to the sensor so it would go in further.
The pickups are roughly in the centre of the "teeth"
Bolted in place.
Upright in place just need to connect power to the sensor and take the pulse wire to the ECU (See May 22nd 2013)

On with the air filter box and just about completed the final prototype, which may end up being the final version if I don't get it made up somewhere. Problem is I have a metal cutter but not a metal bender so the edges for the tags are really bad. Maybe I'll try and fill the bad bits and then spray paint it black.
It's quite a tight space between battery and air intake. The top of the box is slightly below the bonnet so I can place a rubber edging between.
This will be the approximate size of the hole in the bonnet.It can't be much bigger than this as I want a tight contact between the filter box and bonnet.
The scoop will have to be bolted quite a way back on the bonnet.
