Vanagon digifant distributor on ebay, perfect for megasquirt conversion Options

[Cano]

Check it out. Hall sensor, perfect for megasquirt conversion -- drops right in type 4 case. I'm not the seller -- just thought it was a good deal that someone may need.

Please elaborate.

Please elaborate.

for MS, you need a signal to trigger the fuel (and spark depending on version)...
some people use the coil collapsing (kettering)..the signal from the hall sensor is "cleaner"

[DBCooper]

You can do the same thing with a sensor on a toothed crank wheel, but on a T4 with standard cooling there's no "easy" location for the wheel except behind the fan, where you'll never see it again. So that distributor is a simple way to trigger electronic injection and/or ignition, Megasquirt, Megajolt or anything else.

That gives me an idea for a trigger wheel.

But, can the Hall sensor be used as knock detection in this case?

I am going to use this same distributor for my megasquirt conversion. It is a great and easy solution for those wanting to control fuel and spark. The distributor has a hall sensor rather than points, which, as pointed out above, is a much "cleaner" signal for megasquirt to use than signaling off the coil. It also has no built in mechanical or vacuum advance, which will allow megasquirt to control the advance and dwell. (Obviously, for those only using megasquirt for fuel, this lack of advance would not be desireable).

Otherwise, I would be looking at modifying a 009 distributor so the mechanical advance would not work, allowing megasquirt to control the advance. Plus there could still be problems with missed events or false events due to the noisy signal.

Anyway, these distributors are not the easist to find, so I thought somebody with or thinking about megasquirt would like to know about the one on ebay.

a hall sensor is a motion type device (something (magnet) has to be turning or passing by the sensor)

I am not sure how a knock sensor works, but I would guess it's like a microphone

Anyone interested in a used Digifant distributor should be aware that the wires and plastic plug in the housing frequently fail. The failure is age and heat related, and they nearly all fail, sooner or later. I sell a lot of em.

Is there any rebuilding/improvement that can be done to make them better? Sounds like a good idea for a megasuirt system. Anyone know the price new?

Cap'n? would those be new or rebuilt?

Cam Sensor for COP ignition and sequential injection. Combined with a router board it should be cool.

Dave,

Your running EDIS, aren't you? Have you thought of coil on plug with MS? I am planning to build a system, but am still reading up on the suubject.

Mark

[DNHunt]

Yep

Thought about it. I even have the coils. The issue has been controlling 4 coil drivers and 4 injection drivers. The router bord will let that happen with CAN communication. The 36-1 trigger wheel is fine for the crank position and the Hall effect dizzy can provide the cam position. The problem is the router board has been at least 2 years and I haven't seen it yet.

The truth is it probably wouldn't be a noticable improvement from the system I have cause getting the last 5% of performance out of any system takes a good tumer and a dyno. I'm a tinkerer and just enjoy the doing and I don't have that much experience tuning . I can get close but, I'm sure there is more available. Beyond that, once it was tuned I'd only leave it alone for a week or so and then I'd start playing again.

I'd just enjoy opening the engine lid and watching people try to figure out the puzzle.

I am looking forward to getting into it myself. I have a lot of work ahead of me. I stripped out most of a parts car for practice, adn am now working on the one I am going to build up. I am most likely going to go with MS so I can get very involved with it.

I have another question for you. I will most likely go the same 2270 route you did, but am planning on flares for more tire. How do you like your set up and does it break loose if you jump on it?

Thanks,

Mark

[DNHunt]

It requires one to control their right foot. I couldn't argue against more tire. If I ever get around to body and paint I'll probably take it to John Kelly for a slight massage. I'd like to keep the stock fender line but, be able to run 225 on 7" rims. That won't happen for a few years though.

Dave

[Zimms]

Understood. Thansk a lot for the info!
