Question Greddy Emanage

I am in the market for some engine management.....anyhow i cant afford a Vishnu Tec 2 setup so i started lloking at the LINK, but then the Greddy Emanage came out....is this the answer? I can get it with moth harnesses for $475.....will this have the same effect as an AFC on my 2000 Impreza RS? Will the ECU just LEARN to deal with it and over ride it? Will this solve my timing problems and Fuel MAP? Is it similar than the HKS F-con? Is is Superior or inferior? Any info is GREATLY appreciated! THANKS!!!!!

I have an emanage installed on my car, and have for the last few months. It is a great unit and the price cant be beat. I problem with this unit is the software and programming cable. Greddy will not sell this to normal customers. This means that you have to get an Authorized Greddy Service Center to tune your car.

With the additional harnessed the Emanage acts like the F-Con. The stock ECU does not really notice that the Emanage is overriding the fuel signals. It does not use the MAP sensor signal to "trick" the ECU. The Emanage has its own maps that lay on top of the Stock ECU maps. The same goes for timing control if you get that harness.

Don't forget the Haltech E6K when considering engine management. Only $1300 for the kit. Not as easy to install as the Link but a very powerful ECU nonetheless.

Don't forget the UNICHIP

It takes care of timing, fuel, additional injectors, nitro, higher RPM/revlimiter, ...

I'd go with the Link2 or the E6K unit. I've seen E-Manage F-up a couple cars first hand already in Japan. Its basically decent enough if you want a piggyback but not as widely tuneable as the Haltech or the Link.

You guys are comparing Full ECU's to a piggy back. The Emanage is much more like an SAFC and ITC than a Link or a Haltech.

The Emanage works well as long as you stay within it's limits.

Considering the price of the Vishnu Tec II ($2475) does it really kick butt enough to warrant the price difference?

In addition to knock retard and boost retard, the new J&S can modify the MAP voltage, like an AFC.

Yes, the tec-3 from what I've heard and experienced with the Link 2 is worth the $2500. It is easy to use, very very powerful, and will do most everything you could wish an aftermarket ecu could do. Does the price also include 500 dollar injectors and fuel rails? I dont remember if it does.

I would skip the piggyback mess and get either the Haltech E6k or the Link 2. You dont have to worry about the stock ecu learning over the fuel map at part throttle or throwing missfire codes. You can see the entire map in 3d via a laptop. Also the datalogging, boost control, anti lag, flat shifting, launch control, and all the other features will end up being things that you wished you had.

250hp is a large jump up from 165hp. The stock ecu with piggy backs will work, but I dont think you'll ever be able to tune it and leave it with piggy backs. There will be the MIL and ruff idle and transitional det and small stuff like that. Those things will get to you and it will get to your engine as well. Gas mileage will also suffer and the carbon from the extra gas will build up, and lead to more det.

I really do think the best way to go is to get a aftermarket ecu for anything over 3-4psi. Even at 5psi det that you cant hear has destroyed engines. Our pistons (if your still using the stock pistions) arent strong enough to take a lot of det. Tough choice, but now that I have the Link 2 I kinda wish I had gone for the Tec-3 even though I'm only going to be boosting 7psi. Looking back I'm very glad I went for the Link 2 instead of piggy backs and I know if I were to do it again I would do the same since I dont have the money for a tec-3.

-Chav


P.S. The haltech E6k is also a great buy, don't overlook this one.

Piggybacks work OK as long as you aren't pushing the limits. 250hp is getting pretty darn close. Programmable engine management allows a lot more flexibility obviously, but also helps your engine run better than just tricking your stock ECU. Any time you do that you're warranting a little bit of trouble as the stock ECU sometimes doesn't handle certain situations well. My priorities have always been engine management and transmission upgrade before turbo kit just to make it proper.

The J&S is ALWAYS worth it. When properly tuned it's basically a $500 safety switch for your engine to keep it from blowing a rod.

The new J&S yanks the TPS line to 5 volts at 0 psi. This should kick the ECU into open loop.

Anybody out there try it yet?

An SAFC and ITC are more than enough for what you want Adam....I used this with great success on my own car when it was a turbo'd 2.5

If not, save up a bit more and simply get the LINK2 Plug in...very nice introduction to standalone, doesn;t cost an arm and a leg, easy to setup and tune.

TEC3 - I would not make it your first attempt at either install nor tuning..it is ALOT more ecu thatn your combo needs. Don;t get me wrong, in the world of standalone, it is my favoritem, bar none, under $5k....but given your goals, total overkill

adam... do you have have larger injectors in there???? if you do you'll need an AFC... shouldn't drive around without it... if you have stock injectors... i'd say take out the TCII and it will prolly solve your problems... i had the TCII on my car.... ran like a snot then... took it out.. and it was fine...

I talked to a local shop up in Everett. They one of local shopsthat deals in the Greddy E-Manage software. Doesn't sound too promising. They knew nothing about it and yet they are supposed to be one of the only shops in Washington that is a "qualified" Greddy installation center. Thumbs down for Greddy. I think that you are going to have a problem with product support with that one.

I really think that standalone is the way to go with your car. Have you tried using a 2.2L ecu. That might be what you need to have your car running better. The 2.5L wasn't intended for boost. At this point your car is a lot like an original 2.2T with higher flowing heads. At this point I am talking out my ass and just throwing out ideas.

Stand alone all the way.

I have to tell you, the shop that did my install had never heard of one either. They got it installed, and tuned in like a day. It is that easy. The physical install is just like an Unichip or AFC/ITC combo. You just tap a couple of wires and bypass a couple more. Easy.

The programming of the emanage is just modification from the stock values. You add or subtract fuel for each cell in the map. same with timing. So you install the Emanage, and dont tune anything and your car still runs exactly like it did before.

If you are at all considering buying an SAFC and ITC then look at the Greddy piece. Much cheaper, and even better options.
