Vr clearance and angle adjustment

[andy198712]

Hello,
Got my EDIS stuff today, very excited (sad I know)

My trigger wheel is a equaliser pulley that's been drilled so may or may not work.

For edis 4 I want my sensor 90 degrees to the left of my missing tooth right? My missing tooth is at 3oclock position so I need my sensor at TDC but this leaves little clearance, is it ok? Is it ok to be a bit off, ideally I'd have it a few holes to the right, can I adjust for this in my ms1 2.2 extra?

Here's some pics



Ideal location


Your thoughts?
Cheers

or a smaller VR sensor....?

I have my sensor positioned at 10 degrees after TDC and it is about right.

If your holes are drilled in the pulley already you are stuck wit the TDC position.

Your only option is a different VR sensor or redrill the holes in a different place.

If you run different MS code, and build a coil driver circuit, then you can put your sensor anywhere, and program the ECU to know (what degree) the missing tooth is at. This is much more versatile compared to the locked in 90 degree before TDC#1 requirement that the EDIS module requires. You can use all your current hardware, besides the edis module.

With your current config that sensor would be toast if you lost a fan belt at high rpm.

Cheers guys, what ms code is that?

Might try it, then swap to a smaller vr sensor I think I know the Mazda one is small

Cheers!

You may want to move (or have Doc move) this thread to the megasquirt forum.
I think MSExtra will allow you to configure where the missing tooth is positioned. I'm not certain though, I don't have any actual MS experience.

There are smaller Ford VR sensors too, I'm running a '89 mustang vr sensor and it's half the size of that one. So are you going direct fire or staying edis?

How about a two way cross-reference and leave it here for searching. I am contemplating something like this for the future.

Yh true, does it have to be ford for edis?

For the time being I'll stay edis, I have the bits and it simple and will get me rolling, then direct fire my big build maybe.

Cheers guys!

Hello,

Currently have MS1 2.2EXTRA
I thought it did but unsure if the edis liked that or not....

[andy198712]

Are abs sensors VR??

[MarioVelotta]

Currently have MS1 2.2EXTRA ....

Can't do direct VR with the 2.2 board without a daughter board. The V3 board is the first one with an onboard VR circuit.

[andy198712]

Got ya! I got some ms bits in a box I'll look, I got two blank 2.2 boards, relay board and ms2 chip and loads of bits but no daughter board I don't think .

Happy to stick to edis for now

[MarioVelotta]

Yup, EDIS or a hall sensor instead of your VR v2.2 works fine with a hall signal!

[andy198712]

thats interesting to know thank you! do i need the daughter board for the hall?
