Now here is some stuff for you guys that are thinking standalone check this out and do a comparison to see the difference. log on to AEM EMS STANDALONE SYSTEM. take a look and tell me what you guys think.It all depends what a person wants to pay and there goals.

Well I’m not saying anything about stand alone but as for the piggy back ecu I well say the the greddy E-manager w/ Profec e-01 is way better than the SAFC 2.

The Megasquirt really isn't that hard to put together. They have fully detailed instructions on how to mount each component, a dedicated forum to help people out, etc. I recently talked to my friend with a turbocharged fifth gen. Celica ST and he's running Megasquirt and said it wasn't hard to build or setup at all. And it was his first time soldering a board and stuff.

And although there may be some things that it can't do, it's plenty powerful to do what most people want. And it'd be plenty powerful for me...so why would I want to spend an extra $800+ for something like the AEM EMS or something like that?

Celicaspeed, can you list some of the stuff that the standalones you like do that the Megasquirt doesn't do?

Oh, and by the way, I fully agree with Nik on the E-Manage vs. S-AFC II issue. The E-Manage can control things like ignition spark where the S-AFC II cannot.

Its all there for you to research it all depends what you want.In my opinion you know what I think is a better system.But for what you wantperfect and it still is better than the piggy back but for controlling fuel and timing etc the piggy back is all set up and ready to play.Like I said it all depends what the person wants and wants to spend.The e manage is better than the safc2 but it has to be the eo1.Than it come down to price on how much you want to spend. safc2 $250 vs a manage eo1 $450-500.

easy to read monitor data logging able to record and can store different maps just to say a few. And if you want to talk about price dont bother i got the Profec e-01 brand new 350 the e-manage used like new 140 w/ ignition/injector harness so total so far 490 i'm about to buy the pressure sensor with harness so i can have a 3 bar.
grand total $600

gotta love ebay >>

Thats it! Got to love ebay and hope to get the best deal.I love ebay!

That's assuming what Coomer wants to do... but that's not all he wants. The main goal would be to eliminate the AFM on his Silvertop 20V... not just fuel control...

As for mac... he's gonna be doing a 5SFTE... which pretty much *requires* fuel control. You gotta assume he wants a bit more adjustability than that... since he's asking the questions here... right?

Kwanza you got a point!

you know it >>

well, i heard one bad thing about megasquirt from my local tuning boys, who done several cars with megasquirt... there is practily no IDLE or idel is very very routh... and it is not adjustible in a easy way... Dont know about this, but this backed me from megasquirt...

Can someone confirm this?

Your tuning boys must suck at tuning. The first step in tuning anything is getting the idle down. After that with a wideband it should be a breeze to map out the rest.

you would be surprised what cars they done, but with megasquirt they had problems... and all those problems where the same - IDLE...

thats what im sayng... they tune everything, and they sell everything, and they build N/A cars that do 10.3 in 1/4 mile... But ya, you are right, they suck.......

The idle should be tuned first. There is some difficulty to it, but there are also other adjustments besides the computer. You gotta be able to user all of those things together to make it right. We've had a couple of cars come in for minor things that were running megasquirt and they were all DIY tuned and they all had stable idles. This was an RX7 I'm talking about also...

Jumped in on this thread on the 3rd page. Read a little bit of it but im sure its full of "Just 3sgte it"

If you go with standalone do a 5sGTE. With the standalone you can control the 3s head with no problems. Yes you can put a 3s in there but where would be the fun?

stand alone
CP pistons + Total seal rings
3sgte rods or your likeing
3sgte head (P&Ped)
5s block

This would be a fine settup and the biggest flaw would be the trans. And if you look at it that way many of you swappers have the same trans.
