Time to go to a stand alone

[JStoked]

So I'm getting 750 injectors. My tuner said that my piggy back (neo) was not going to be enough to control that big of injectors. So I'm going to go with the mega squirt stand alone. I know devin likes them alot and it seems like the right way to go for the price and my hp goals. So any info on them would be awesome?? And yes my tuner says he can tune it.

Just curious as why you are choosing megasquirt over all other standalones? I dont know much about it but after looking over the site briefly it looks like a build your own standalone that takes quite a bit of programming. Is the price that much better than getting an AEM or similar counterpart? If so wont you be paying more for the tuner to make the system then tune it?

I've heard that AEM still has problem with the 7m ISCV

if you can install and tune a standalone, you can install a Ford ISCV and never worry about it again. hell, my car with the AEM idles fine with no ISCV.

If you have a knowledgeable tuner, you can have your motor start up with no idle speed valve. It will all be done based on the cold start map and you will just use the throttle body screw to keep it open just a little. The later throttle bodies don't have this screw BUT you can add it simply buy just tapping and adding a 4mm allen bolt.

I can vouch for magesquirt. We've been using them for years on various vehicles. Mainly with MS2 on our race car: MK1 MR2 4agze converted to 4agte with ge intake mani. and td04h 13t turbo. Thing was easy to tune and ran like a dream once all setup and street-tuned. We're going to MS3 this year after we rebuild the 4a.

Megasquirt's cost vs. capability is just unmatched in the industry. If your a tech geek with some soldering/electronics experience, it is the best solution. If you go MS3 you can have a complete stand alone that is every bit as capable as any top of the line pre-assembled stand alone out there for a lot less. You just have to do more of the work yourself. It's worth it if you can do that. Tuning with it is easy if you know any basic tuning programs. Tunerstudio is the one we use.

Buy your stuff from these guys (best place to get megasquirt components): http://www.diyautotune.com/

And here is the MS3 kit: http://www.diyautotune.com/catalog/megasquirtiii-wpcb-v30-unassembled-kit-p-397.html
You can go with the MS2 for about $260, it just has less features than the MS3 so it will depend on what specifically you need for your setup.

All you need aside from that is a wide band, which you can go with this and you're all set: http://www.diyautotune.com/catalog/innovate-mtxl-gauge-sensor-controller-3844-p-467.html

You also need to wire it up and tow it to the tuner as well don't you?

Vs plugging in a aem and driving it to te tuner or plug the aem at the tuners.

 

[Enraged]

the "base map" with the aem is not driveable. it is just enough to get you started (usually), it needs a lot of adjustment depending on your engine setup.

 

[IBoughtASupra]

I find it hard to believe that Megasquirt can compete with AEM and all the output options. If you have looking for something simple, it would work but why not have a system that can run all the electronics in your car including A/C and has more inputs to display parameters like fuel pressure an oil pressure.

You have no idea how big of a ProEFI advocate I am. The damn thing tells you which cylinders have a misfire. The box it ny that expensive when you look at what you get and a lot of the sensors are rebranded AEM or GM ones.

 

[MPR]

I am not familiar with ProEFI so I cannot speak for it.

MANY people underestimate the capabilities of megasquirt and I think a lot of that has to do with personal bias and not actual facts. All you have to do is actually look at what MS3 can do before you assume it's less capable simply because it is cheaper or more of a DIY setup.

You would not have to tow your car to a tuner to have it tuned if you know any basics about tuning and how an engine runs. You can start with bare maps or download someone else's maps for the same engine and tweak it to match your setup to get your engine running. Once it's running (idling), tunerstudio can take over (to a degree) with auto-tuning to get the engine running smoothly, and then you can manually tune from there.

Our MR2 never saw a dyno. We street tuned it and it runs much better than some professionally tuned cars. It's mainly used for competing in autocross and we had a power band (peak turbo efficiency range) from 3000-7500rpm at about 10 psi boost with not a single hick-up or throttle tip-in issue. A/F ratio was rock solid as well, right on target at about 11.5-12:1.

Don't discount something you haven't tried or haven't done serious research on. I'm not slamming AEM or ProEFI or any other stand alone. I'm not saying anything negative about them besides their cost. What I am saying is that MS is fantastic, cost-effective and too often underestimated. MS3 can do coil on plug, fully sequential fuel injection and much much more.

MS has Safety features?

MS has Safety features?

What do you mean by safety features?

It has various features such as over-boost protection and many others.

 

[JStoked]

Wow this all great info!! The reason I wanted to with the MS is because every one knows that I will probably get frustrated with the 7m and do a 1j or 2j swap and I wont have to change the ecu agian just pretty much do a little adjusting and BOOM I back on the road. And so far we (I say we as me and my brother) are doing pretty good with the innovative lma3 that we just got.

 

[IBoughtASupra]

Boost cut, AFR tracking, fuel pressure drop, oil pressure drop, cylinder misfire indicator, sensor faults, adaptive knock control, rev limiter, valet option and all of these will trigger a check engine light when conditions are met.

I have seen Megasquirt but there has been so much more advancement in the EMS world, it would be a waste to go with anything else besides a EMS unit.

Why not just do the 1JZ or 2JZ swap now and stop spending the money on the 7M which you will get rid of?

From the research I have gathered from pro shops, forums, and owners MS2 is a very good setup some say easier to tune than the aem.Some say aem, I was gunna go MS3 but its to much for me to do with no garage IMO. My Aem base tune hydro locked my motor because it had the fuel pump priming for 3 minutes or something. I am not advocating for either as I have no tuning experience and still havent got my aem setup so just my 2 cents. P.S. the aem forum for an 87 setup is a wall, many people try to get help but unless you have a honja or emo wpix me to car your outta luck. well 1j and 2j gets help. The good part is if you have your stock ecu you can drive to your tuner pull it on the dyno and plug it in and go.

Because I'm not done learning on the 7m yet. I love the torque of it so far.

you must have done something seriously wrong to have an injector stuck wide open for 3 minutes. the fuel pump priming will not flood the motor, it will just cycle the fuel through the rail.

the aem base tune isn't great, but within about 20 minutes we had the car somewhat driveable, just by adjusting timing and fuel, enough to get it safely to the dyno.

 

[IBoughtASupra]

Enraged,

The base map timing was aggressive for you?

 

[Enraged]

no, we had to advance it a bunch if I recall. also had to take a bunch of fuel out, as it seems to be set up on the very rich is safe side. like clouds of black smoke, 10:1 everywhere safe.

it doesn't really matter too much which standalone you run, as long as you have a good tuner. Bill at Independent Speed Shop has helped me immensely. My car is actually enjoyable to drive now, better than stock.
