what stand alone ems's are avaliable for the 420A powered eclipses? which one is probably the best? i was going to use the s-afc, but my demands are going to be a little bit higher than what it can give me. i seen an accel one i think one ebay, what is it, and is it any good? is there like a universal aem ems that you can program you own needs into? as you can see i dont know much about the stand alones, so i can use all the help i can get.

Some guy on 2GNT i saw had spliced a aem ems to his 420a. dunno which one or how just saw he did it.
 
Lotsa guys on 2gnt are running the 034EIC 8 injector setup, and as /\/\/\/\/\/\/\ said, someone there has also spliced in an AEM EMS or is in the process of doing so.

It also seems that a lot of guys are going to the Megasuirt. I have heard that a lot of MR2 owners have had success with the Megasquirt.
 
what exactly is that megasquirt? where can you find info on it? also i was thinking about this. say you run 10psi for daily driving and you want to turn it up to 15 for the track or something. what do you do? is there something where you can have two seperate fuel and timing trims? b/c at first i was going to just use a s-afc, but then i got thinking about problems like this. how would you solve that?

i dont know if it has 2 different set ups but i would imagine you could because its save on a lap top, so why not save 2 seperate files, but maybe look at the Greddy e-manage. its about $300 or so to start, then like $35 for the fuel and $35 for the timing add ons. then like $115 for the computer link. but you can controll fuel trims and timing.
 
The Megasquirt is temp sensitive, so the fuel maps will change according to temperature unlike the 034EIC 8 injector system. But as already said, if you have a laptop, then there is no reason not to have a few settings saved for diff air temps.

Go onto 2gnt.com and talk to Mr. Slick. He knows a great deal about the Megasquirt.
 
you could also go with the F.A.S.T. system that is the one I was going to go with until I bought the AEM EMS.
Now the AEM EMS is a custom job to splice it into the 2gnt system because AEM dose not make a plug and play standalone for our car, but for the money it's one of the best systems out there right now

i would love to go with the aem but i knew they didnt make one for our cars. do you know how to do the splice to get it to work on our cars? if not do you know where i can find out how?
 
I just have this to add and you might like to hear it.

You can buy a built MegaSquirt from Mr Slick at 2GNT for something like $285 shipped. Then you can buy whatever wideband O2 set up you want (I'll be getting the Zeitronix ~$400). The MS has an input for your wideband. Tell it what AFR you want to run, and the MS will adjust your fuel at any given point on the tach, under any load, in any gear, and adjusted for current air temps (remember, you have wideband now), and you never have to deal with it again. Mr Slick has recently been able to decode the crank signal with the MS and soon will be offering ignition control with it as well. It will be upgradable too, so no having to wait for a new model in the future. So basically, this is the set up I'm going with. I'll have total fuel control under any circumstance with wideband O2, and will be upgrading to ignition control when it becomes available later this year and still have paid less than a grand.

If it gets any easier than this, I don't know how. You could buy something like the AEM EMS and then hack and experiment to get it to work, or you could save some money, get this set up, and have it work perfectly right from the start and have a decent amount of support from others with it on the same car you drive.

Try throwing Megasquirt in Google and see what you find. You'll be surprised. Not much on the 2GNT platform, but trust us. It's being done and it's the best bang for your buck. I was going to go 8 injector and use the 034EIC, but this is SO much better. :thumb:
 
so basically your telling me that if i hook this thing up and tell it i want to run lets say a 12:1 af ratio it will automatically adjust under any circumstance to that a/f ratio? so say i'm running 10psi, and i want to bump it up to 15 for a pass, will it comensate for this? also how do you control this thing? do you use a laptop? does it have tables you can use like other ems systems.
 
Those would be some in depth questions best answered by Mr Slick, but yes, the MegaSquirt adjusts fuel pressure on the fly. I copied this directly from the MegaSquirt website.

All of the embedded microprocessor code executed in MegaSquirt was hand-written directly in assembler, not compiled from a high-level language. Working directly in assembler produces the tightest and fastest-executing code possible, even compared to the most efficient C compiler available. The result is that MegaSquirt can provide real-time fuel calculations up to 16,000 RPM!

...

MegaSquirt uses an oxygen sensor as feedback for mixture AFR control. MegaSquirt is compatable with single wire (unheated - like Bosch Part Number 12014, used everywhere ) as well as heated units. All parameters that control the feedback (step size and rate, range, trip threshold voltage) are user-controlled. Additionally, since the trip point voltage is user-defined, MegaSquirt is compatable with the DIY-WB (wideband) oxygen sensor board - one simply sets the desired air/fuel ratio trip voltage and you are there.


You will need a laptop to interface with the unit for sure, but depending on the requirements, you may be able to pick up a suitable one on eBay for super cheap. You'll have to ask Lee (Mr Slick), but I'm pretty sure he runs (and IDLES!) with 780 injectors. No small feat if you ask anyone with a turbo 2GNT. :thumb:
 
AS far asI know there are only two 2GNT's with an AEM EMS Mine and one more www.pfispeed.com is where I got all my work done

how hard is it to hook one up? also which one do you use? and i take it that this place knows everything to splice one in on our cars right?

hey dr1665 how can i get ahold of mr. slick to ask him some questions?

OMG Wow, that sounds incredibly dangerous.

Only if you tell it some off the wall, half assed AFR. Otherwise, it's going to use your wideband input to keep the AFR exactly where you want it. Can't get much better than that imo.
