cam sensor setup plate

[sumoashe]

I am very interest in this for an M30 I am building for my E24. How is the project coming along? Does it look like getting completed in the next few months?

As a matter of fact the project is moving along. Talked to my manufacturer today and should have a working prototype in a month. Once testing is done and everything is finalized I'll put up some info.

Definately in for this, need a setup for my M30 this will save me having all the same design work done! keep us posted! hope the project is still moving along..

I'm still keep an eye on this, hoping it is going well :)

Sorry for the lack of updates. Been ungodly busy with a move and house remodel. Not to mention working on starting my own business. But to the topic, These are coming along nicely, currently doing testing on the m10 version of this setup for the 02 guys. Also working on final packaging of the m20 version. Basically making it good looking as well as functional. Will actually be looking for a couple testers for the m20 units coming here shortly. Still don't want to put these up for general sale until I'm 100% on everything.

As I only really know the general's on m30's, is the rotor mount in the distributor the same as those in the m20's? I know they use the same cap and rotor, but not sure on the actual mount. As this may cause enough of a spacing issue to need a specific m30 unit.

For those interested in this. My word of advice is to start planning and budgeting. This part by itself wont give you full sequential, still need a ecu that can handle it. Not to mention your going to have to basically make an entire wiring harness to utilize it as stock won't work. So keep all this in mind as you plan.

Good advice. Looks like a decent product. Going MS is on my to do list for the next year or so.

I'm No expert in the specifics of m20 vs 30, However I am very experienced in Standalone management and hybrid engine swaps/Turbo conversions. If you need a tester i happliy volunteer to test for M30 fitment. I'm the resident "old stuff" guy for Eurocharged Canada.

I'm in for one of these. going Ms3x semi-soon.

I am in too. Will be going MS3X with full sequential on my 91 325i. Keep us posted.

When using an E46 cam sensor are the intake and exhaust sensors basically the same? These are 3 wire Hall effect right? I read that Hall effect sensors generally require an external magnet but the E46 just needs to sense ferrous metal nearby? This makes it a gear tooth senor then?I am using a small piece of steel with a single gear tooth bolted to the metal 3 arm rotor piece. I can tell there is a small magnet in the E46 sensor I have but it is nowhere near as powerful as the magnet in the stock VR crank sensor on my B35. Do the E46 sensors need to be basically the same distance away from the tooth as a VR sensor (say about 1-2mm) would? Just trying to get a little better idea of how theses work.

I also read that the sensor should be located somewhere between tooth #1 and TDC compression but then read somewhere else that if the sensor is placed there the ECU will have to wait one more revolution to see the missing crank tooth #1 again. Which way is optimal for megasquirt?
Thanks

Bear, the E46 is a gear tooth sensor as far as I know. The distance between sensor and pickup will def make a difference. I would try to get down to that 1mm. Not exactly positive on this but the material used for the trigger might make a slight dif aswell. As different materials have dif magnetic qualities.

On the placement question. I can't say specifically on the megasquirt setups but most guys set the trigger event just before cyl. #1 compression tdc, then adjust via timing control from there. It's not super important as the timing is set via the ecu, you can put it before or after tdc by a few degree's. As long as it's on the compression stroke. The main thing to look out for is that the cam and crank triggers don't occur at the same time. The simplest way to think is the crank trigger handles fuel, cam trigger handles spark. As for the ecu having to wait another rotation isn't really an issue, all this means is maybe one more revolution during cranking, not running.

Forgot to say, pm nando as he built a setup with the E46 sensor and uses megasquirt.

Thanks for the info. I am starting to read more of the msextra threads which are helpful. I found out that for my combo the best order is gear tooth cam signal then VR crank signal tooth number one which is then followed by the engine reaching TDC. The cam signal informs the ECU that its on the intake cycle and the crank signal informs the ECU the engine is on its way to TDC compression. I just need to settle on a cam sensor and modify your plate by adding an aluminum spacer to give the proper air gap between sensor and the tooth. I know they have adjustable gear tooth sensors but they seem to be less robust and would end up a lot closer to the radiator.

Are these still being made?
