MegaSquirt
 

Is any body here using MegaSquirt?

I am thinking about building one for my turbo setup, and would love
to hear from someone who has already done it!

I believe there could be some problems with the Coil-On-Plug setup the miata has,
but other than that it looks very good!

And cheap too, for a complete stand-alone.
I saw some guys have posted success stories in the megasquirt forum,
but they seemed to be only using the MS for fuel, keeping the stock
ECU for spark.

If you guys have any success/failure stories, please share them! :)

Do a search on www.miataforum.com There's one fella that's running Megasquirt, and he posted a couple times about it fairly recently.

Maybe we should start a megasquirt forum... I think it could be the next "thing" for miatas...

Yes, that might be a clever idea!

Although the MegaSquirt scene has their own huge forum
which helps people with everything, it would of course
be great if people that are trying to fit the MS into a Miata
would gather into this forum :)

At least if I go this route I will post my setup here!

exactly, anything to get a few more posters.
Keep us up to date on your setup, once we get a few people that have done it and have some sort of knowledgebase going I'll open a forum and we can archive all the info/howtos/whatever there.

It's always better to have a model specific forum than a general, look at the amount of emanage info for the miata here vs the emanage yahoo group for example.

Another guy reporting in that was thiking about using MS. It seems its not too bad to get it setup as a piggy back for fuel. So at least you can use it to run like 440-550cc injectors. MS is also cheap; 299 prebuilt and with wiring harness. My only fear is what about spark? I as of right now understand little about how the miatas ignition system works but I think it may be hard to get working with the miata. From my research the miata's CAS is the same/ simular to the one in 1st gen DSM's. I would really love to use MS but not if I cant do spark. I would love for some headway made on using the megasquirt for the maita.

I too have been thinking about the MS for a couple months now. The only problem for me is that barely anyone else has done it for the miata. By using it as a piggy back, it costs about the same as an emanage, which more people have used, so I think I'm leaning toward the emanage now.

Yes, it's true that it seems like not very many people have succeeded in installing it
as a stand-alone ECU in the miata!

But I think it's totally possible to do it, and if it is successful you have full control over
everything for 250-300$!

That's very hard to beat :)

I have found only 2 suscess stories for maita installed with MS and i think both used it as a piggy back, and they were smart mofo's. While cheap it would be easer to use a 1000$ haltech and save a crap load of time in the process. I am a huge fan on the MS but I daily drive my miata, I cant spend a month figureing out wireing and how to get it working right... Maybe I exaggerating how hard it would be to get an MS to work on a miata....

Ok im bringing this thread back from the dead, you all know you want to try MS!
The issue is ignition, MS appears to have never been built to control spark. (some guys later made a hack it appears that allows this) I think the miata has to be converted over to a completly different igniton system thus making a lil more than 250-300. I have no idea how to set up the MS for spark and fuel and from seaching MSefi.com has come up with nothing. I cant learn how to do it if I cant find any information. If anybody has any info on the MS being used for fuel AND spark for the miata please let me know, so far I dont have the slightest idea.
I guess you can always use the MS and bipes ?

By the time you added a bipes into the equation it would be too close cost-wise to the e-manage.. (for my anyways) but idk its something different which is always cool

well JUST the e-manage ultimate is 500, (still gotta buy shit like a map etc.) MS+ used bipes is much cheaper. Which you can better tune? who knows, but I hear the MS is pretty slick to tune. I really dont know which is better overall.

MS is very cheap if you buy at in component form and assemble it yourself. You just have to be handy with a soldering iron.

The blue Emanage is nowhere near $500 and would give you fuel and timing. Maps are all over the place and freely shared. I know you are really itching to try MS, and that's fine 'cause it adds an alternative to the mix of information, but there is a lot more history and help available on the Emanage.

Yeah I wasnt putting MS down or saying its bad I was just sayin EM would be my choice of the two for reasons stated above.. I also said in an above post that it would be cool to try something new and different.. so more power to you hope you start a new "thing" :bigtu:

Well the blue Emanage cant run bigger than 330cc injectors without having issues, while using the MS and it seems the newer EM-ultimate wont have these issues. 330cc are not really big enough without an afpr like the begi or messing around with disks from the vortech. While if you can get the MS working you can use 460cc or 550cc injectors from a rx-7 and have plenty of fuel. Not being able to control timeing easly with the MS is kind of a showstopper. I still dont get what you have to do to control timeing, switch over to ford EDIS?

can't compare MS to an emanage, MS is more comparable to the LINK

Ya the MS has a lot of features, its cool stuff.
Anyways try searching 'DSM wheel' and see what comes up. (in other post I said I think the cas is some how simluar... Seems that way you can use it to control spark, I really dont understand it yet. (seems like nobody is intrested anymore in the MS????)
If anybody finds some info regarding MS and the miata post it here :bigtu:

Yeah, I was asking my EE/ME buddy about Megasquirt the other day (this is the same guy who built a fuel injector driver for a car of his as a college project), and he said his younger brother is running it on an early 90s Volvo 940 Turbo. He said that, to control ignition, his brother had to convert to the Ford EDIS ignition system.

Could you perhaps ask him the cost to convert over to ford's EDIS? I imagine its a pain in the ass to do this haha

Yeah, I might be able to find out what all parts are needed, etc. Actually, and I don't want to get anyone's hopes up prematurely, as it's probably at least a year off or so, but my friend and his other brother are currently working on a piggyback ECU that'll control injectors, ignition and all sorts of other cool stuff you can think of. They've already got the boards and cases and have successfully got the injector drivers working in basic form. They've also got one working on an RX-7 Turbo II right now as a fuel-cut controller, to allow it to run higher-than-stock boost pressures.

Right now, the ECU only drives low-impendance injectors, but they already know of the potentially big Miata market if they incorporated a piggyback fuel controller, AFM delete option (by way of a simulated circuit through a MAP sensor, TPS, etc.) or an AFM-to-MAF convert , wideband autotuning, O2 clamp, ignition control (or at least the ability to pull timing, a la Bipes), water injector control via RPM, injector duty cycle, pressure sensor, MAP sensor, etc. The architecture is pretty open-ended, so really the possibilities are endless...they'll entertain whatever ideas people have if the market's profitable.

We've got some fun times planned ahead :)

EDIT :Realised you were not talking about MS

Well, my friends' piggyback would probably end up costing more than MS, at least a basic MS with no ignition controls, simply because it's using much more advanced hardware. It'd probably be more in line with the price of the e-Manage Ultimate.

Ya they could make a crap load of money. Hey if they ever get to the "beta test" phase I would love to test it on my miata :bigtu: haha

just try and keep it out of the turbo hey?

Dammit I was going to mount it inside the air filter too. It seemed like a dust free place :skid:

ok time to spam some more stuff I found interesting about the MS:
RE: spark
Like I have said a few times I think the miata cas and the DSM cas are the same

I read threw the LONG ass post about using the DSM cas to control spark with MS. If anybody wants to take a look its here
The jist of it many were able to get fuel and spark going with limited or no modifcations needed. The MSnS extra code (found here)
Add's a lot of great features take a look. I really want to order the parts for the MS or buy a prebuilt one when i have the money...
Oh ya the guy that already has the MS on miata.net said he is going to try to add spark sometime around xmas/ thanksgiving. I am keeping my eyes peeled for it.

every time i see MegaSQUIRT, my mind conjures up pr0n... :gay: :p :bigtu:

ditto, :gay:

hell someone send me their car and the parts. I've got nothing goin on...

..... see my other post

Ohhhhhhhhh yeah.
I smell new forum :bigtu:

You might want to try the basic fuel only setup first, piggybacking the ecu. Then when your ready load up the ms and spark extra firmware.

MegaSquirt II with IGN control
 

If these megasquirts work the way they can, i would fall in love and probably marry one. So cheap for a unit like that.

MS-II doesn't support the MSnS Extra Yet. You are better off getting the V3.0 boards with the orginal ECU. When version II develops you can just upgrade.
