Megasquirt? What's the Situation?

[Erik]

Having already gone through an ECM issue, and of course wondering about the DIS (anyone have a spare on their shelf they don't need?), threads related to these always end up with references to Megasquirt. However, I've yet to see a thread that goes into the whole process of swapping to it.

So, my questions are:

1) what's involved in doing the swap? How many hours for a competent mechanic to it?
2)Aside from the Megasquirt 3 (?) controller, what is needed to make this work?
3) What are the costs of getting everything?
4) What instrument panel functionality do we lose?
5) How is reliability of the system?
6) What questions do I not know to ask about it?

Looking forward to getting educated.

I think RussMcB had one. You should reach out to him. Or call MegaSquirt directly.

Thanks.
Talking to Russ too. Pretty good feedback from him.

To my knowledge the unit is supposed to be plug and play, but will require tuning.

Nothing I don't think

Cost of the unit $2000-$3000 plus the tuning hours

all the fuel stuff (Avg, Instant, DTE)

The basic premise is used in a bunch of applications so I would expect it to be decent (Russ can answer that)

It does not replace the Ignition module, it uses the stock one

Thank you! That answers a lot. Not a bad solution to one area of ZR-1 issues.

I'm a bit confused (not the first time). I see references to using Megasquirt to replace the DIS. How would that work?

It is my understanding that with the mega squirt you can use the factory dis for plug and play operation. The mega squirt also has additional outputs that you could setup to run individual coils for each cylinder and not utilize the factory DIS and coils.

I thought I read something like that.

Gonna reach out to the good folks at Megasquirt for some clarification too.

base ms3 pro is about 1100 with the fly wiring that you need to install



you essentially take away all the engine management functions and there are issues with interfaces for mileage computer, security, ect...


gauges work fine. you for sure WANT to run coil on plug and I think the ecotec 4 turbo coils or the merc marine coils plug in perfectly


the megasquirt can drive the 16 injectors fine and has dual wideband, flex fuel capability, and a wide range of boost control and tuning features that make it a very good option for anyone that has "lost the dis"


the LT5 ignition system is quite good, and works fine, but since they are going up in price, the MS is a viable alternative. The raptor "plug and play" version retains the stock ignition system which I wasn't fond of as selling a "good DIS" will about pay off the megasquirt


I'm looking to do this, as the tuning opportunities are significant and the coil on plug is superior and much less hassle to maintain.


If anyone needs a DIS, reach out to me. I have one off my 95 and would for sure pass it on for the right price to a needy owner. Jerry is working on reverse engineering and will likely have a solution soon, and fortunately the DIS rarely fails. But when confronted with that, know that there are options!!!
