Default Anyone running EManage on a 98 RS

I have a 98 RS with a completely built, balanced, blueprinted motor with cobb spicy cams, ported heads and every bolt on imaginable. I am trying to figure out what to do with engine management. I think the greddy emanage would be a viable option for me but I don't know if it is overkill. I am planning on doing a low boost turbo sometime after the winter and I would like something that will still be good even when I boost to 6 or 8 lbs.

Can anyone chime in with *educated* pros and cons? I don't want to know what you've read from what someone else's friend's brother is using. I want to talk to people that either dealt with directly or owned any of these systems. Don't forget, I have a 98 so I have one of the "dumb" computers.

Greddy Emanage
Rallitek's Perfect Power
S-AFC and ITC

Thanks in advance...

For those of you who are going to tell me to use the search button, please save your breath. I've been on 25RS, nasioc, i-club and everywhere else on the internet. I've been reading on the computer for the past 2 hours and my eyes hurt. I just want some good answer before I go crazy!

I don't have any input on the Emanage or PP. I have gone for a ride (during normal driving and on a road course) in a turbo'd OBS that was using piggybacks (S-AFC, ITC, and I think J&S knock sensor). Compared to the two turbo'd RS's I've ridden in (both with TEC3s), the piggybacked OBS-T felt very, very unrefined. It was like the various piggybacks were fighting each other at various points in the rev range. My sample is just a single vehicle, but based on that I would not advise using the piggyback approach.

emanage does what it says it will, but good luck getting any support with it. If I had the 'dumb' ECU I probably would have taken the S-AFC and been happy. I like all the bells and whistles the emanage has (via the support tool), but you're pretty much on your own to figure stuff out. Get some Visine and keep searching. Nabisco and 25rs.com user "BOY" has lots of experience with the emanage, search up his posts.

Lots of emanage info and links here:

Thanks man. I sure as hell hope computer screens don't emit any funky rays b/c I'm sure I'll have some kind of brain tumor. Thanks for the info. I'll check that stuff out.

Don't worry, if you don't already have the tumor, trying to make sense of Greddy's manuals will give you one.

You can find tons of support for the emanage in the Aftermarket FI section. Its what a lot of turbo RS's run. The emanage will take some time to figure out, and you will have to do some reading, but it is extremely powerful.

I used it before, and I would definitely recommmend it.

Thanks for all the info. Now all I have to do is figure out if I can find a place with an AWD dyno and that has experience using the Emanage.

Oh, redwagon, I'm sure my brain is going to be fried after reading that manual, hence the reason that I'm trying to save it now!

Is the wiring very difficult? Does anyone make a harness for my car that I could use instead of cutting and splicing into my wiring harness?

Easy wiring, all at the ecu. No adapters though, must solder.

No, even with all the options it's not hard to splice in. I used OEM-style connectors to splice mine, so I can isolate and disable different circuits for troubleshooting. Took a few hours, half a day tops, mostly because I was being careful soldering every joint and checking everything twice and three times. (my engine did start and run fine on the first turn of the key though...)
What's more PITA is getting it to communicate with your notebook or getting the main unit firmware updated etc. If yours is well-tried application you should do better than I did. My car is a MY'00 and a 4EAT, seems no-one has done that before, judging by the lack of material to search up and the crickets that greeted all questions. For example, jumper settings that work fine on manual MAP cars do not work with the 4EAT. If you're unlucky you'll spend days trying undocumented jumper and switch settings trying to get your engine to run, or get rid of CELs. Greddy's software is far from bug-free and many times various functions will fail for no obvious reason, but will work if you keep trying.

Lotus is right about the power of the device however. When you get it to work it's great. The weak part of the hardware itself is the ignition driver transistors, but those settings are the most accurately documented part of the install/setup. You shouldn't have any problems there.

The emanage support forums are pretty much dead, maybe there just isn't that big a user group in the English-speaking world, and maybe the Honduh guys are just loathe to share info. There's a lot more chat about the emanage on the boards here in Taiwan, but that doesn't help much if you can't read Chinese... The Japanese boards are also a goldmine of info.

You'll need Boy's install notes: http://f5.grp.yahoofs.com/v1/4IklQ2k....5_Emanage.doc

The faq at that site is also very useful.

I highly recommend Simon's clone cable. Direct USB to emanage, no adapters needed. PnP solution.

Lot's of other people have said this, but to be sure: You don't need to buy both the injector and ignition harnesses. Get the ignition harness and you'll have plenty of wires left over to make your injection harness.

They do actually make some plug and play harnesses for the WRX/STi now, but unfortunately nothing for us older models.

Wiring is not hard at all if you have the right information. ECU pinout and the color coded Greddy instructions and you're all set.

Jumpers can be a bit of a pain, as I've shared some copies of my map with others with nearly identical mods (and the same MAP based 00 ECU) and they got much different results than I did.

You may think no one has done it before (which may be true for NA builds), but there really are a lot of users. Search through the aftermarket forced induction and there is tons of info.

I was on the computer almost all day at work reading up on stuff. I found a place near me that has an 4 wheel dyno and they sell and install the Emanage. If I have any problems with it, I'm sure they'll figure it out when I go down to tune it.

Anyway, from the looks of things, I am going to go with the Emanage Ultimate. I think that'll be my best bet, not to mention that I've actually found it cheaper than the regular emanage. I'll keep track of this site and let you know when I get that and put it in.

That seems like a good place to start. Half my trouble was that the only guy around here with a wideband and det cans is working almost exclusively with european cars and the Haltec or some Unichip widgets, never touched an emanage before. Buy and tune at the same shop and they have little choice but to get it working 100%.

You want to share the price on the ultimate? PM me if you can't post it. I can't believe you got it cheaper than the gold, they're about double the gold price here. :jealous: It would be so nice to be able to trim fuel directly via injector pulse width. Not to mention the use of a regular dime-a-dozen USB cable.

LotusTT: I'm sorry if I sound ungrateful. You're one of the very few (as in fingers of one hand) guys who had an answer for my many n00b questions.
As you say, there is quite a bit posted here and there about the emanage. Sadly, as OP suggests, much of it is from people who have never actually used the device, will only discuss it in regards to a FI application, or simply piss on it from their exalted height of UTEC/Hydra/Ecutek splendor.

Thanks for sharing your experience with us mere N/A mortals!
