Greddy Emanage

[x2fast4u57x]

I was wondering if anyone has ever used a Greddy Emanage and if its any good? I heard that it basiclly destroys ur coil pack. So wondering about other peoples feedback on it.

you shouldnt leave the car in the on position without running for a long time with the emanage. It will eventually fry it...other than that I love my emanage. Its very easy to tune and log with.

Ok thanks, Just wondering because i wasn't sure if i wanted to go with an AFC or emange.. I really wanted an Emange since its a piggy back and user friendly unlike the AEM..

Does anyone know a shop that is realy good at tuning the e manage?

[ray@turbotek]

(---------- no shop

but really good with the emanage

Does anyone know a shop that is realy good at tuning the e manage?

That's the challenge right there... nobody really likes tuning it. Is AEM the only other DSM option?

I think there are better options than emanage as it is just an "offset" based tool.

ECU is not a good place to skimp on your car.

so what other PIGGYBACK would you suggest. Emanage controls fuel and timing on an easy to control map. and it logs.

The problem I see with most piggybacks like emanage/unichip is this:

They work soley on intercepting the electrical signals between the stock ECU and applying electrical "offsets" to tune for fuel and spark advance. Fuel is normally fine like this for most setups and this is how a Super FC works. Most stock ECUs dont alter fuel tuning in any kind of feedback loop in high load, high RPM conditions.

Spark advance is something that CAN be an issue on certain cars. This is ECU dependent based on the algorithms that are used to control spark advance. YOU NEVER KNOW EXACTLY WHAT TIMING YOU ARE RUNNING with these piggy backs. All you see is a +X or -X in the matrix cells. This is OK in most cars that don't have adaptive ECUs and like to run repeatable spark timing.

I've noticed cars tuned on these tend to let loose (if they do at all) in about 6 months or so and here is my theory: The stock ECU has compensations for fuel and spark based on ambient temp, and coolant temp vs RPM. Your tune was done on an unknown stock compensation based on the conditions that day. Now comes winter or summer with drastically different conditions that the stock ECU corrects for. Problem is that it could advance timing 1-2degs or run a little leaner, etc. This isn't accounted for on the piggy back and tune. Engine starts getting into knock threshold and doesn't last long at these new conditions.

Still, you have to have in depth knowledge of the existing map on the ECU and know where you should be. You can't just directly set for spark advance, it is an indirect method with these. I'm not saying it can't be done, but it isn't as straight forward. Also remember that spark advance is the most critical tuning variable. This is why UTECs have their own (standalone) spark advance capabilities that run instead of the stock ECU controls.

NA cars, they aren't as bad and are a good option. Turbo cars just have way too many variables for a comfort level with me.

well i agree....but with an older ecu, like mine. I think the emanage works fine. Its possible that my ecu doesnt have much of a different setting for climate changes and just runs a slight alteration. Plus if you tune conservatively you can account for your ecus changes

if you gotta stick with a piggyback for emissions purposes... stick with emanage. It's the most versitile piggyback on the market IMO. Otherwise find a competant tuner and go with the EMS that he's most comfortable with.
