Is megasquirt worth it?

[equate975]

I'm looking into starting my mega squirt setup, and I am having some second thoughts about it.

Mainly, it looks kinda ghetto honestly. My main problems are

1. no sequential injector firing, they claimed it would be working by mid 2007, well thats like a year ago.

2. COP is sketchy at best, looks like the best "workaround" is to use EDIS to fire the COPs. Again supposed to be supported mid 07

3. No knock sensors.


At the same time though, it looks good and its cheap. Plus I would like to set it all up looks fun ;) And I suppose COP and sequential firing and probably knock sensors will eventually be put into it.

Any thoughts?

There's a reason its cheap, but its alot of bang for the buck as well. And has alot of features.

A proper tune will mean that you won't have a need for a knock sensor.

Yeah, but I would still like to have knock sensors just in case.

I actually just found out that supposedly the COP and Sequential firing addon will be out "soon"

Weather it will actually happen or not I don't know. Maybe I should put it off until fall (when I originally planned on doing it) and hope its out by then.

If you have MS2, the MS2-extra code has sequential COP capabilities already. You just need the dual VR conditioner, assuming a VR sensor for the cam. I am really happy with mine. I'm just running alternating batch fire (3 cyl at a time) and wasted spark with stock coils. The great thing about it, and any other standalone, is that you do what ever the hell you want and not need an expensive ass tune, no air meter (no intake restrictions).

Wolf EMS is the way too go but its quite expensive though.

Yeah I actually just noticed that. What COPs are you using, the bmw ones? Looks like they are a bit more tricky to wire, IIRC they are 5 wire right?

What VR sensor did you use for the cam too?

Considering that the M20 is a non hydraulic engine, a knock sensor would have to be so de-sensitized that there is no point in having one.

COP? Why?

[equate975]

Who said anything about a m20? I'm talking about a s52....

[DSP74]

Im dumb.

[E30ownerwithanopinion]

it all depends on who you are squirting on.

I still just don't see why you are so obsessed with a knock sensor, the factory ones aren't even as valuable as you think. For example, I work for Mercury MerCruiser, our lead Tech Writer used to be the lead at Mercury Racing. Some of their bad boy engines tuned to run 93 without knock sensors, they did enough testing and determined that running 91 didn't warrant a map change or even a warning other than to run premium.

If the engine has a proper tune for the octane readily available, you aren't going to have a problem.

If you are just looking for reasons to not use Mega Squirt, then just don't use it.

I install Mercruiser setups everyday. I head our propulsion, and hull prep areas.....Installed a 350 mag today (and a few red engines too...)

^Then you can give me some feedback on the 700 hours of work I just put into the Inboard and Tow Sports Applications Manual, got the Catalyst update in there, but still no Total Command.

5-wire? What the hell are you looking at? They are just normal 3 wire coils. One trigger, one 12v, and one ground. I have two VB921's connected to the 3 (standard) spark outputs. Each VB921's has a 660 ohm resister. I've got the Glen's Garage idle board to control the stock ICV. Talk to GoatHumper on BF.c or E30tech. He is actually looking for beta testers for his new adapter board. Pretty much you just plug your stock harness into the adapter board and plug the relay cable between the MS unit and the adapter board. Makes things MUCH simpler.

Um you could send me one. As I'd like to have it. But for the most part it's not something I'd need to refer to. PM me if that's something you can get out and I'll send you my company info.

Any reference material on the lower HP Mercury Racing packages would be nice........We've recently installed two 525 packages, and I'd like to look into something as high as 850HP..

Also currently with the american dollar what it is, and for other reasons, BY FAR are biggest dealer is in Germany and he distributes throughout Europe. Two turbo/super charged Diesels from Volvo just went over. I suspect he will want a few M/C packages installed as that is what he usually opts for.

Quick question. What are you guys developing to replace the 496 Mag stuff?


Um sorry guys. I guess this should have been put somewhere else
