Well, I've been reading up on Megasquirt lately. I'm strongly considering using it on my VQ in the future. It's a full standalone ECU for dirt cheap. http://www.megasquirt.info/

It would of course allow any changes to timing and fuel that you could ever want. So it would be great for NA or FI setups. Wiring it is simple, tuning it would be my biggest challenge.

I've got a lot of learning to do about it but it looks like changing to a Ford coil pack setup my be necessary (easy enough, cheap too).

Any thoughts?

Can it read our crank/cam sensors, or would you have to change those out too?

 

Try contacting a guy named etx on my350z.com. It sounds like he has some experience with MS and was thinking about using it on his Z...

I don't believe it requires a cam sensor, it does need a crank sensor. I believe you'd have to mount the trigger wheel on the front pulley and mount the new sensor next to it and ditch the stock front and rear crank sensors.

You have to know your valve position in order to inject fuel and fire your plugs. With some programming, for rpm, you can get away without a crank sensor, but you have to have a cam sensor.

Looking at the page a little more, you can see it was developed for engines using distributors. No COP system is currently available.

It looks like more of an educational/training tool than something you would put on your daily driver. I didn't see any mention of feedback control so I guess it is fulltime openloop.
