Greddy E-Manage Ultimate

[BhamRoadrunner]

Does anyone have any experience with this setup? Or the original E-Manage for that matter?

Will it do what we need it to do for upgrading the major componets of turbo, fuel rails, heads, exhaust and intake? Or is the only option we have something similar to Acutek or LINK? (Which by the way, I've found Acutek for bikes and whatnot, I'm guessing it's the same system? I haven't found LINK at all)

I know the cheapest option would be to go with the "Build your own engine management" (the name escapes me at the moment, i apologize) however, I don't have access to a 4 wheel dyno within 100 miles of here and I'd like to at least get a road tune in the mean time, hence the Greddy E-Manage.

I have used the Greddy E-Manage Blue on my GL w/EA82T, delta 272 Stage3 Cams, Gen3 Ported Heads, 440cc Injectors, TD04-13g turbo, MSD Ignition, WRX Top Mount Intercooler, 2.25inch Stainless CATLESS exhaust and Perrin Boost Controller.

I used it to tune the whole setup fuel and timming and got around 200whp out of the setup, very nice unit but the only issue I had was the fact that the stock MAF system on the 87 Hotwire Loyale Turbo's is not a normal 0-5v signal its actually higher than 5volts so the Emanage Couldn't see the rest and adjust accordingly I did work around it with the pressure sensor but it was patchy at best.

I now run the Ultimate on the car and I'm making 260whp@18psi and I even deleted the factory MAF The ultimate is badass and is the best system ive used to date, I love the AutoTune Feature via a Wideband O2 Sensor, makes tuning SOOO EASY. Base Maps can be had in minutes

Welcome to the Board to the both of you!

Steveman09, sounds like you've got a hot setup on your EA82T. How easy is it to tune with the Ultimate? I mean, for an em noobie like me who knows hardly anything about tuning, what's the probablilty of me using it successfully? How much is the unit and where do you get it from?

Yeah I set out to do what others told me wasn't possible with the EA82 Motor and have baffled everyone, its a very durable motor and I allready have around 20k on the rebuild, all HARD miles and it shows no signs of giving up yet.

The e-manage ultimate was a little confusing at first but once you learn how to use the software and figure everything out its very easy to use. There is an AUTOTUNE feature that basically just requires you to plumb a Wideband O2 Sensor into the exhaust (before the cat(s) And then it will automatically create a base map for you while you drive around it will get you around 14.7:1 AFR which makes Tuning MUCH easier and faster. Then you can datalog your WOT Pulls and watch the Wideband O2 Sensor Readings and dial it in yourself without a Dyno. I did it this way and when I actually got to the dyno just to see the power output he was amazed that I managed allmost ideal AFR's across the board without a Dyno Tuning Session, only thing I really improved on with the dyno was timing which gave me a few extra ponies.

You can get the e-manage ultimates for around 500-600 bux (everything needed, harnesses, manuals, cd, cable) On ebay, I see them there allot, other places will try and sell em for 800-1000 easy.

The Ultimate is basically a standalone system, its the only piggyback system that is about 90% standalone, even has a revlimter feature which was nice on my EA82 since it didn't have one factory.

[93Leg-c]

Thanks for that info.

So, how long did it take to hook up the unit? And how long before you got it tuned (WOT pulls, etc.)?

[Legacy777]

Can you elaborate what you mean by it being a piggy back, or 90% standalone?

Is it truly a piggy back? Does the factory ECU still stay in the loop? What signals does the ultimate intercept/tweak?

Thanks

[Legacy777]

PS, going to move this to the electrical forum, as I think it fits better over there with some of the past engine management discussions.

[Legacy777]

bump....anyone?

Basically all the stock ECU does now is control base ignition timing to start the motor up and maybe a few other select features like Air Conditioning Idle Up, Cold Idle Up and Base Idle Control.

Other than that the e-manage ultimate takes over everything else.

Here's a small list of only some of the things it controls :

RPM Revlimiting via Ignition -or- Fuel (You can set any rev limit point you like, even if the stock computer didnt have one like the ea82)

AutoTune via Wideband O2 Sensor to create maps fast and easy

5th Injector Controller

Nitrous Injection Control

Full Control Over Ignition Timing (Advance and Retard)

Delete Mass Air Flow Sensors and Convert to MAP/Pressure (EA82 MUST)

Ability to switch between 2 Fuel/Ignition Maps with an External Switch (IE: Race and Street)

Factory Boost Cut Adjustments (also you can remove it completly)

Full Datalogging

Realtime Knock Sensor Compensation and Monitoring

Fuel Enrichment based on MAP/TPS/MAF

Factory Speed Governer/Limiter Delete

Automatic Transmission Ignition Compensation/Adjustment for Shift-UP/Down Points

Distributor Cars can be converted to Group Fire or Individual Ignition Systems and Group Ignitions can be converted to Sequential

Individual Cylinder Injection Adj. & Individual Cylinder Ignition Adj. Maps (correct uneven combustion between cylinders, by fine tuning each individual cylinder for more advanced tuning)

Vehicle Speed Compensation (Futher Tune for Speed/Load Conditions)

There are many more features but I'm too tired to list them.

So as you can see this is as close as you get before spending 2 times more money on a 100% Standalone and the Emanage has allmost all the same features minus a few select.

[Legacy777]

Looks very promising.

Has anyone installed this on a turbo legacy yet?

Does it have the ability to control boost?

For $500 & $100 for the harness....it's definitely a little more then the SMT6, but it looks like it will do a whole lot more. My only concern is that it will have issues like I had with the SMT6.

From this pic, they do show it to work on the BC/BF EJ20's

I hate to pop open an old topic like this but I was looking at getting the Greddy E-Manage system and had a question as to whether or not it would work in a 97 Legacy GT with the automatic transmission. A friend of mine told me that the ECU in that model is locked to not accept a piggyback unit. I was just wondering if anyone else had any info as to whether or not this is true.

[cj91legss]

You can make it work with just about any car, im going to be installing this in my car sometime soon (already have the unit)

Thanks for the info. I knew the ECU was locked to prevent it from being tuned. I was unsure of whether the whole not accepting piggybacks was true or not.

[Legacy777]

All the piggy back ECU's do is modify the signals going to the main ECU.....So in theory it should work.

[cj91legss]

i would like to know more about thsi guys ea82 setup and his tuning on his emanage ultimate

[93Leg-c]

Hmmm, I had totally forgotten about this thread. 97LGT and cj91legss, please let us know all about how the Ultimate works on your cars if/when you install it. I know I'd be VERY interested in knowing your results.

[cj91legss]

yeah my project got put on hold for awhile, but i'll definately be putting up some info when it's complete. i had to buy a new Keyboard for my laptop and now i have to eventually get a wideband. im looking at the AEM wideband, so hopefully that'll work with the emanage auto tuning options it has

READ THIS...as it'll answer a lot of questions. Even the same car, but a 5-speed.

Tranny shouldn't matter and the Greddy has a 'map' section for tuning for the 4EATs.

I'm also running this on my '98 Forester, which uses the same ECU as yours - mines a 5-speed.

[93Leg-c]

Td, is your Forester still NA or did you turbo it?

Still having issues w/tuning...not sure why but my setup is a PITA to get tuned. The guy I bought my EMU from had a very similar setup (same stock NA ECU) and didn't have nearly the issues.

[93Leg-c]

Ah, ok, that's the project in your sig. It's too bad you're having tuning issues now but when all that's solved you should have a great setup.

Here's my ignorant question of the day for you or anyone to answer: Can I use EM on a NA engine? My '98 Legacy's engine's performance is so far from optimum and I'm wondering if the EMU could at least correct the factory's deficiencies.

You'll have to get more detailed....

The car should be 'optimum' w/the factory ECU. Define what you mean by how it runs vs. how you think it should run?

If you have issues, such as poor idle/MPG/etc. the EMU won't fix those....and could blow up your engine by trying.

First of all, it's a '98 Legacy w/ 2.2L NA engine and AT, compression on all cylinders at 154-156, idles smoothly, MPG is about 24.5 average.

I THINK it should run somewhat close to my '93 2.2L NA AT Legacy. I realize there is a difference between OBD1 and OBD2 systems and that the OBD1 systems had less strict emissions which means better performance than the OBD2s. The '93 AT pulled strong off idle (it would put my head and my passengers' heads back into the headrests with just minimal pressure on the gas pedal--if I floored it from a stop it would always beat any 4 cylinder, non-high-performance car, like if I wanted to switch lanes and get in front of the other car). By comparison, the '98 is quite sluggish. If I floor it off idle, it just sits there for a moment and then accelerates non-vigorously like it started off in 2nd gear or something. With the '93, I felt confident merging onto certain freeways with very short on-ramps with only 3/4 pedal; with the '98, I wouldn't even dare try it with the pedal floored--I will actually drive 5-10 miles on surface streets to get to an on-ramp that is long enough to build up to freeway speed (65 mph).

In addition to the overall lackluster acceleration, on (what should be) brisk acceleration (gas pedal depressed 3/4 way or more) the '98 has a "hole" when it hits around 3,000 rpm till about 3800 rpm. Many second generation 2.2L Legacy and Impreza owners will tell you the same thing (like guys on NASIOC). Acceleration just falls off. When that "hole" is reached, I've noticed my front passengers sometimes lean forward from the decline in acceleration force. Some of my friends who don't have much enthusiasm for cars and driving will sometimes notice and ask me, "What's wrong with your car?"

There are rare moments when suddenly the car will seem efficient and powerful (for a NA engine) for about a second or so and I think, "Hey, this car is finally working right." But then it will fall back into its lethargic pattern of under-powered performance. But that second or two is what I think should be its "normal" performance; that is how my '93 performed all the time.

(This is a side point, but the acceleration hole in my '98 reminds me of what's been written about the twin turbo Legacies that have that "valley of death" hole when they accelerate. It often made me wonder if somehow there is a common denominator to the NA and the TT engines' "hole" in acceleration.)

Since some of the guys on NASIOC and sl-i seem to take good care of their cars mechanically and still have the same issues that I have, it leads me to believe that the factory setup is not set up properly. Hence, my wondering if the EMU (or any other piggyback system) would be able to maximize the capability of the NA engine.

[wtdash]

Ok....well then.....this is interesting and enlightening.

I wasn't aware of this 'hole' in performance.

Have you read of anyone fixing this issue? Any info over on the USMB site?

[93Leg-c]

I have not yet heard of anyone completely fixing the "hole"; however, what seems to help is modifying the intake--replacing the stock intake tubing after the air filter box with an aftermarket aluminum mandrel bent set up. What I've done so far is use a stock '96 intake set up--it removes that big air box (can't think of its proper name right now) that sits inline just before the throttle.

This alteration in the air flow gives a rather noticeable improvement in acceleration and overall performance (and even gas mileage). But this again seems to indicate to me that there is further performance and economy gains to be had with a piggyback system. Does my reasoning make sense?

I have not yet checked USMB, mainly because of a lack of time but I will do that. Right now I've got to get going for some appointments and won't be back till evening.

Oh, BTW, Td, I appreciate your input! Thanks!
