Anybody in here have any actual experience with the Megasquirt EMS?? I'm looking for tuning options for my engine. I read up on it a little bit last night, but I'm wondering how it compares to AEM or FAST. How much does it cost? And, also, I'm being told it doesn't work with OBD2, and my car, unfortunately, has OBD2. I'm going all motor for now, but down the road I may, but not likely, add a turbo. I'm not exactly new to tuning, but this IS my first GM build, so if anyone has any advice here

Greddy E-Manage, or the E-Mangage Ultimate. I will be using the E-Manage Ultimate to tune my new motor when it's done.




I was a retard, and now I'm permanently banned.

I don't think the Megasquirt is a stand alone. Its a piggy back like the AEM and GReddy if I'm not mistaken. For a true stand alone, run a Haltech.

the aem is a stand-alone. it costs 3000 $ CAD for a reason. It replaces the stock computer



15.574 @ 89 mph stock

I've heard/read a lot of good things about F.A.S.T, reson why my built turbo motor will be using it





................Which car will hit 400 whp first???................

I ran the AEM on my CRX when it came out, and I've used the FAST before, but I haven't seen where they work with this application. On my CRX, it was easy. Take out the old ECU, plug in the AEM unit, plug in a laptop, start tuning. Do they have one that will plug in to the Cavalier harness or are they going to stress me out and make me hard wire? Spotabee, I know you and I talked a little about the Apex'i AFC, but after thinking about it, I really think stand alone is the way to go. I think thestock ECU is just going to get in my way.

My entire engine harness will be replaced with one for the FAST system

So no, it's not plug and play, but its what you need to run 2 bar correctly

The newest version can be used as one.

The original megasquirt is a standalone fuel system. It will operate your injectors independently of the stock ecm / pcm. It is not OBDI or OBDII but will work in either system.

The latest MS is a standalone engine management system. It will deliver spark and operate your injectors independently of your stock ecm / pcm. It is not OBDI or OBDII but will work in either system.

Both versions are DIY and need to be assembled.

Are any of the other systems mentioned above capable of controlling the electronic transmission in some J's, or capable of running the instrument cluster & etc? If not, then why spend $3000 for an aftermarket system when you can get the same functionality from an OEM OBDI ecm for 1/3 the money? And with the extra cash you can pay to have the car dyno tuned, buy lunch for the dyno operator, and still have money for gas at the end of the day.

-->Slow

If OBDI is so versatile, why aren't pro-draggers using it?

I got my FAST system b/c I knew it would work with the harness I got with it

Another question, why would there even be an aftermarket for stand-alones if OBDI was so easy

The fact is that when you have 100% full control with the EMS and software you have and know that it will work why try to retro-fit a system that is 10+ years old

My FAST system will control an electronic tranny and is capable of running a cluster

But the people that use these products don't use that stuff. They buy autometer instruments to get precise readings and probably would rather use a hydraulic tranny b/c pressure readings prove better than given shift pints

Maybe it's just my opinion, or I have just drank a lil too much

But I know I made the right choice when I bought my EMS

what is the site for the Haltech.and the FAST systems.can anyone tell me?

megasquirt is IMO better than AEM becuase its soo cheap. Alot of people here sware by AEM and say megasquirt isnt proven but A local 2g talon just went 11.6 on stock internals and 30 lbs of boost..
It helps we have a megasquirt GOD in the midwest

What exactly are you trying to do?, I doubt a full standalone is nessesary

Well, I'm not worried about controlling the tranny. I'm running a 5spd and limited slip conversion. The instrument cluster isn't a big deal as I will be converting to Autometer or possibly Defi for monitoring the vitals. The basic need I have is tuning flexibility. I compete in both drag racing and autocross, so I need that flexibility and control. Also, the engine modifications are strictly regulated in autocross, so squeezing the most out of what I have is very important to me. Also, I plan on moving up in classes once I have more funds to add other engine mods.

then Haltech or F.A.S.T. are superb. But have fun spending money. Lots of money.

So, Spotabee, do you think I should go with the Apex'i AFC like we talked about instead? I think with an MSD setup and enough time on a dyno I could probably get what I need. Autocross is more about balance than power anyway. I'm in the Touring Class right now, and that class doesnt allow changes to the ECU itself. I won't move up to Improved Touring (where ECU and other changes are allowed) until I get the money to build the car to full spec. The AFC is legal in my class, they let us alter fuel and timing either mechanically or electronically, but not both, and as long as the signal is altered BEFORE the ECU, it's fair game.

So you are allowed to run piggybacks? You're set up until complete standalones, considering there is no "modification" you can do to J-bodies like Hondas for example, with chipping and socketing. Now... I'm not a big fan of the SAFC. Some people will swear by it. But I prefer a much better accurate tune with a standalone design piggyback like the E-manage. And at this point, I'm saying go E-manage or Megasquirt in addition to the MSD DIS-II

I have megasquirt II on mine and have had excellent results. tuning with a wideband i have improoved driveability, performance, and economy. it is a true standalone in that it can manage the engine independant of the stock pcm. as of yet i am unaware of anyone sucessfully controlling the stock ignition with it but converting to ford edis is easy & cheap. it can be aquired as a kit or can be purchased assembled from companies like diy autotune or rs autosport. if you do go with megasquirt i cant stress enough how handy the harness kit available from rs autosport is. if anyone has any questions about megasquirt, installing it, or tuning it i would be happy to answer them on here or hit me up on aim, SCII Roscoe.

If your not scared of a little soldering MS is great,
In my opinion it's just as capable as any other stand alone .

I'll be running a Haltech E6GMX


it requires an AC Delco OBD1 ecu connector, and a little figuring out

also pictured is my 3 bar MAP

Well, I'm not 100% sure what I'll be running with the new motor (bye bye bolt-on-crazy LD9, Hello built Ecotec and loooooots of Nitrous) but I've been giving some serious thought into running the Holley Commander, uses all GM style sensors and has more bells and whistles than I know what todo with... (I'm not tuning the car... so I'm letting the people who will pick the standalone)

Oh yeah, its box price is only ~$1000usd... sure more expensive than the Megasquirt... but the M/S is kind of crude IMHO... I'd love to throw one at my Dad's 83 Chevy truck (carbed 350 that suuuuuuucks back the gas) but not for my car.

Haltech E6GMX is about $860 on sale with 3 bar map sensor right now.

The Holley is a great tool, but either haltech or holley, us 3rd gens are stuck making a whole new harness.

We are using the F.A.S.T. on our sand rail with a 2.2L Ecotec. They will all pretty much do what you are looking for, in the hands of the right tuner.

F.A.S.T. is amazing. I'm listening...

whats the site to the F.A.S.T system, i searched for it and did find a European company called fastdta that looked like a good system for $1050-1580 depending on what you need. But i don't know if its the same company
