I don't know if anyones seen this or if this is what started the thought pattern behind this thread, but, Nov. 03 issue of Turbo magazine (the one with the title "WRX Killer" with the silver EVO VIII) has an article on 17 EMS's. Everything from AEM to TEC3 to Simple Digital Systems (SDS). Even though it isn't perfect and not completely comprehensive it has tons of useful info and is written to compare each system side by side.

instead of starting a new topic..add to an existing thread...

so heres my question

What about this megasquirt setup..its very inexpensive..has anyone got one?

as for motec (what i want..3d maps woo) its too expensive.. ive seen prices from 1500 to 2800 EUROS!

as for the megasquirt ,add a wideband controller.. thats like 350$ plus 350$..not too bad ..


so i saved this thread(search feature rocks!)

now,please discuss

help me tune my turboed 4g63 nt!

Here's a Megasquirt thread .

I have an EMS setup using MAP wich is the way to go if you are going to bother spending all the money on getting one. Setting it up really isn't all that hard. The only tough part is running all the wires and that isn't really even all that hard. It isn't exactly plug and play like some people might lead you to belive, but I can do most anything with it that I would want to. If anyone has questions on it let me know and I will post back.

what kind of ems are you using??
what came with it (aems ems doesnt come
with a map sensor..it costs extra )

If you're thinking AEM or Gen 7, you should at least give Megasquirt a look - since it does exactly what those others do (and lots more if you want) for about 1/8 the price. Pretty easy to build one yourself, and I've left enough detailed posts over this board and MS-EFI that you should be able to get any DSM up and running in no time.


The only people badmouthing AEM EMS are people who are confusing the EMS with their lack of ability to understand engine management. I've tuned a few AEMs and they're very nice and stable systems... totally awesome for the money, actually - so don't listen to anyone badmouthing a standalone of any kind. They all work great, but YOU have to master the learning curve.

Frankly, if I were a shop or a tuner, I wouldn't be talking crap about the AEM. The only problems you can have with it are due to poor installation or a lack of understanding of how to tune an engine with EMS properly. It's definitely a steeper learning curve than DSMlink.

I have the box for the 2G cars. You are tight the EMS itself doesn't come with anything besides a sticker for two and a pinout diagram. You have to go out and get yourself a wideband, unless you want to use the stock O2 sensor which is supported. I am using the AEM UEGO sensor, it has worked fine for me but some people think that it lacks accuracy and are using a sensor from FOJO(?sp).You also have to go out and get a MAP sensor unless you want to use a restrictive MAF sensor. You have two options on the MAP sensor. You can get the AEM one or you can get a GM one. Both work fine, the GM one is accurate up to like 2.5 bar and the AEM ones come in models that are accurate up to 2.5 and 5 bar. I don't remember the pricing of the sensors and the part numbers of the MAP sensors from the GM dealership, but those can be found up on the EMS site.

Hope that helps.

Road Race Engineering shows that AEM has a 3.5(good to 36psi) bar and a 5(good to 60psi) bar map sensor while the GM is only a 3(good to 32psi) bar. I remember using a 3 bar on my civic back in the day with Accell DFI.

Im by no means a professional on this stuff. Just showing what they say. And from what others say they are prforesionals at this DSM stuff.

are your a pro,

[gamingguru]

Ya I guess that you are right about the GM one only going up to like 3bar. But really now, how many of us will really be setting out boost that high?

As far a being a pro at this stuff I would say that I am not. The only car that I have ever tuned has been my Talon. But I was making over 400Hp according to the EMS dyno maths calculations before by 7 bolt blew up. I am in the process of putting it in right now. I do know a lot about the EMS however and EFI tuning in general though I think.

So the wideband replaces the O2 sensor? I read somewhere that even with a wideband you still have to keep the OEM sensor.

You can swap it back in after tuning.

I would'nt. The cost of the sensors has and is falling. If you have a AEM set up the AEM to use a target air fuel ratio and use the sensor all the time. You will never go lean and fry the motor. Even if I wear it out in 2-3 yrs its worth the peace of mind to wear out a sensor that costs less than 2-3 years of oilchanges.
