My friend was telling me that the easiest way to get going with a crank position sensor is to steal some parts from a 1.9L Escort.
The easiest way is Miller Mule for the crank pulley and the sensor.

garion wrote:In regards to my 'cheap megasquirt upgrade', I was thinking that the megasquirt would only control the throttle body/injectors. So the whole idea is this:
1. Megasquirt
2. Some throttle body that attaches to an existing intake, replacing the carb
3. TPS, mega has to know where the throttle is...
4. An O2 sensor to adjust the mixture as needed. Maybe a engine temp sensor?
5. Use the existing ignition system.
I think thats possible, but I haven't done the research. It avoids having to buy crank position sensors and the like, no new intake, and is easily reversible. There might be an even cheaper/simpler version of megaquirt that could handle just this.
Just my idle thought.

This is how mine is set up. The ford module controls Dwell, and sends a PIP(Profile ignition pickup or "engine position") and MS sends back a SAW (spark advance signal) back to the Ford unit based on your tuning parameters. The Ford EDIS system then directly tells the coils when to discharge. Another option available to you with newer versions of MS is have the ECU directly drive the coils independently. You don't get a big advantage to this, But with EDIS remember, its a "wasted spark" system. Everytime the piston goes up, the spark happens - so one is essentailly wasted. Some would say that's inefficient.
You still do all of your tuning from megasquirt - And the software has gotten pretty friggen awesome over the years. I have the tunability to install turbocharger or supercharger or nitrous or rocket pack and i could get it running correctly.
Megasquirt is something i would only recommend to someone who likes electronics and tuning though. It takes alot of work to get one running right.

There is nothing mysterious about the fiat motor - it's very flexible. We can mount about 20 different carbs on it, turbo it, supercharge it, all without removing the head. But don't discount the Bosch system - it is quite effective.

It can probably be tuned by reprogramming - the similar systems used by vw/audi have chips available from various vendors.
But dumping the code, figuring out how it works, etc, no thanks.
I'm not saying it doesn't work well. I'm saying that it's peak performance is a target i am not interested in.

Is it so wrong that I look at megasquirt as something i'd like to learn, and l-jet as an exercise in anachronism that does not excite me?
