Megasquirt

[firebird_1995]

I'm considering buying a megasquirt setup for my FI build. I see where they have added optispark support for the ms2 and ms3 kits with some upgrading. My thoughts are, at this moment I would like to keep the opti as i'm not spinning past 6k and there's no reason to get rid of it, but in the future i could go with any ignition setup without having to change ecms. I'm not looking to have more than 15# of boost and guys have made it work with the stock ecm but should it start to give me problems, I'm going to upgrade before I spend several times what a standalone would cost. I realize these are a very hands on and DIY oriented system. Does anyone have any experience with these?


Larry, if you could put me in contact with bluebottlez I would appreciate it!

Yes he was very helpful. Basically, don't bother with the micro squirt, the megasquirt is better suited for the lt1 platform and take your time on the wiring harness. The biggest thing he said is he would do it again. At the moment I'm looking at buying a used assembled kit so I'm going to avoid a lot of soldering and since I'm not using a computer controlled transmission I won't have to piggyback the stock ecm. Shouldn't be too bad but we'll see.

Im planning on using megasquirt on my next build...looking forward to hearing about your experences with it.

Yea its sad.

Megasquirt is a go. Got a fully assembled and tested one on eBay for $445 shipped. Ill have to make the lt1 mod for it but that's it.

[Ryan Stout]

Did ya get the 1,2 or 3?

[firebird_1995]

Ms2 with the 3.0 PCB. It was the same kit other than the lt1 ignition mod they were selling for $659 on their site. The mod is 2 or 3 resistors, $5.50 iirc. And I'll need a short pigtail ($80) so I came out OK.

[Ryan Stout]

Ok. Making sure its not batch fire. Guy at work is using a 2.0 on his turbo 408 mustang. Seems to work well for him.

[firebird_1995]

I think it can be ran in both but for sure sequential fire. Only issue I might have with it is sequential fire with the msd opti. I've read where a few guys have had problems with the msd opti but not a stock opti so we'll see. Might end up selling the msd

I am using megasquirt on my S-10 v8 project, nobody wants to pay anything for a MSD opti, I put mine on ebay, and it was brand new and I got $265 shipped. There reputation has gone to crap, if you can find somebody that would trade a nice AC delco unit straight across, you will be ahead of the game.

[firebird_1995]

I guess you were not able to make it run right in sequential mode with the msd?

[popo8]

Bluebottle's ta is batch right?

1993.

The s10 is using a tbi distributer and Megasquirt batch fire. It's a old style 355. Not running yet.

You know..... I didn't ask. It looks like by default they are set up for batch fire. If at all possible I'm going to try and run sequential but I don't think its going to make a whole lot of difference

[Ryan Stout]

Yea I'm not sure if it'll make a huge difference, just throwing ideas around really lol. Factory 5.0 foxes are batch fire and they run good with boost. Yea popo, if I'm thinking right, 93s are batch fire also (provided its stock PCM).

What's up with an opti and not running sequential? I thought 1.0 and 2.0 were batch and 3.0 is sequential. Probably wrong tho. We're all here to learn lol.

[Ryan Stout]

I just figured with boost, making a bunch more power than stock, sequential would be worth at least something, especially if its free.

I agree. The issue that I've read guys have is running sequential with the msd opti. Something about the notches in the optical wheel wasn't spaced correctly? I'll have to see if I can find the link again

[Ryan Stout]

Hm, interesting. I'm 24x, but would be interested in reading it. I love learning stuff.

Some good reading here

[bigtoyz]

so the MS3 is piggyback system and MS3 Pro is a stand alone? Not a bad price for a stand alone system compared to others.
