Pre-order: SquirtForce PnP ECU for 90-95 Miatae
 

Introducing SquirtForce! We have a brand new but not so new ECU that will be available in the new year.
This microsquirt-based ECU is small, basic, and inexpensive, but perfectly capable of enabling you to go turbo without any bandaids.
We've stripped back the number of features to make full stand alone as accessible as possible. So if you need sequential spark, onboard logging, or oodles of i/os, you should definitely get the very excellent and fully featured MS3Pro PnP (which we will gladly sell you). If you need just the essentials and an easy plug and play experience, and you don't have an extra $600 burning a hole in your pocket, then this ECU is for you.

The ECU comes pre-loaded with a base map, so just plug it in, follow the simple guide, and fire it up

There are half a dozen SquirtForce powered cars zipping around so far, and we are ready to make this more widely available.
The target price of this little beauty is $599, but we will take pre-orders for $499 until January 1 including shipping within the lower 48. We expect to ship in late January.

No VVT?

No MS2 based MS will ever support VVT.

New feature alert - we've just added two features to the final-for-now design:
1. 90-93/94-95 switchability. That's right, one perfectly acceptable ECU, jumperable between two year ranges.:skid:
2. High current ignition drivers. Power R8 coils and other low impedance ignition options that require high current signal circuits. :firedevil

So no 96-97 compatibility?

96-97 has an extra connector on the ECU and a completely different pinout so wouldn't be possible to make it compatible.

noted, thank you. Any chance a 96-97 ecu is on the horizon?

We don't have any plans for a 96-97 version at this point.

This is why you google your product name before you name it.

Lol. Yeah, the name is a deliberately comical portmanteau for you mt pre-order folks. It's not going to "stick"

For the uninitiated among us, what's the benefit of a Microsquirt based ECU over something like a Speeduino based ECU?

I won't pretend to be an expert on Speeduino, but the reason we went with a megasquirt base for our ECU is that it's stood the test of time. There is 10+ years of questions and answers about the platform, it's by far the most popular platform for Miatas, and every tuner knows and trusts it. I'm of the opinion that you can save a lot of time and effort by following a well trodden path.

I think the main reason folks look for alternatives is price, so we are aiming to make it even more easy and affordable to go with the established standard.

1,000,000% agree

I agree that you can save a lot of time an effort by following a well trodden path.

I don't want to discount the fact that if you have what it takes,
it can be worth it to trod an entirely new path. More options in the market and more paths trodden can only be a good thing.

Additionally, from what I've seen, the speediuno does what it does really well and it's hard to beat it at a budget option.
And you don't have to sacrifice sequential injection.

Also don't let my above reply make me seem unenthusiastic for this product,
A cheaper alternative is only a good thing and these good folks are providing one. Another path.

We are building in an upgrade path for sequential injection. The capability will be part of the base ECU, but no pricing yet on what the upgrade cost will be.
This ECU now has sequential injection.

It's not even sequential? Man, that's wicked lame.

Megasquirt is some primitive bullshit. That MS2 has easily 4 times the processor of a mega based speeduino yet it does like 4 times less.

You all need to let megasquirt die like it should. Especially ms2...

Someone didn't have their Wheaties this morning...

I just get pissed every time I drive my MS3 based miata, sorry. My haltech plugs are here, time to build a harness...

If you need help laying out a dual driver board let me know.

I'm getting real tired of seeing you crap up the forum with this bs hate, ESPECIALLY since you don't even have the haltech working yet or can even confirm definitively that it's better. How about focus this energy on setting up your new ecu and proving to us all that it's the new hotness before you spew more hate? Or crap up a solid/reputable vendor's thread.

I'm working on the design of this ECU. The board will be standard with sequential injector drivers however when used on an NA6 the end user will need to add the circuits to the ECU connector in two empty cavities on the connector (same used by NA8) since the standard harness is set up for batch fuel.

Also yes MS2 is a bit primitive but it gets the job done and is relatively cheap.

This is sweet, I really wish it was around when I bought my used MS2PnP for about the same price. IMO, for most 200whp beginner builds, this is perfect. There's very few places to screw up (relatively), it provides all the functionality most of those 200whp people need at a good price, plus you get all the support and forum info that comes with running MS. Definitely going to start mentioning this more to people who ask about lower budget standalones rather than Speeduino.

I have a MS3X on my miata and I run a speeduino on a turbo F-150. I haven't personally used a MS2 but I've attempted to help enough people on here to be familiar with it. The MS2 feature list is indeed weaksause compared to the speeduino, but the MS2 absolutely wins in the support area. If you just want it to work with limited hassle and don't care at all about the additional price or feature limitations go MS2. If you're willing to spend more time tinkering and you want the lowest cost option or you need features that MS2 can't provide then go speeduino.

There is room for both options IMO.

The only really bad about the MS2 is that it has very little ram and flash. Oh, and the Burn-stumble. Otherwise, given its cost, it's really good.

I think these are really cool. I have been looking at $700 programmable distributors for old datsuns. When all I really need is this with an adapted cam sensor and an ecu harness. I could run individual coils wasted spark.

I remember when I learned that ms3 didn't do that in Nigel's car way back. I was like, let off the throttle so I can hit burn, he was like, what? I was instantly filled with envy.

I had totally forgotten about this until a few weeks ago, tuning the SquirtForce on @Cxracer's Track Rat.

@nigelt It’s actually a bit less noticeable with this ECU than my old MS2. The one upside is you know you actually burned it to the ECU😄.

Just as an FYI, the Track Rat is a running product tester with a 93 chassis/1.6l wiring harness and a 94 1.8l engine swap. Once it was up and running with a bit of street tuning it went straight to LagunaSeca for a track day and performed flawlessly.

this looks like the perfect answer for my car, have been a long time reader and have been running low psi turbo with a plethora of band aids for 3 years now looking for an update next year i think. Where do we place orders? sorry maybe i missed it? .....NVM found you under FLOWFORCE in the vendor page, I don't see it on your website however.

I was doing the pre-order by PM/PayPal, but I can see how it would be more convenient to put an order in on the site. So here you go! https://goflowforce.com/products/flo...-plug-and-play

The pre-order price will bump up to $549 in early January when we move to production.

Last chance for the $499 price. We'll go up to $525 on January 1, $549 sometime mid-January, and then full price at $599 once we are shipping.

We are shipping out the first pre-orders today, and can ship out new orders as needed now. When you order one, you choose the configuration (NA6 or 94-95 NA8), and for the NA6 you have the choice of 4 base maps (batch or sequential injection, vTPS or not). It's been a long time coming, and we ended up making more revisions than originally planned, but I'm really happy with the outcome. Also stoked that we've made it compatible with our new R8 coil kit.
