wattup,
I am about to purchase an aem ems, but the thing is I need the uego. I have yet to see an aem ems w/uego for 2001 honda prelude. If anyone has a part number to this management system plz let me know (if they make) I do not want to get the wrong unit ...
Also, I am not quite sure what im getting myself into with the AEM. Does this unit come with everything you need for the tune or I will have to purchase other parts.
I know this ems does many things but can it be used as a turbo timer?
Plz help me with this, Im very lost when it comes to tuning....
thx
-John

Unless you really know what you are doing, don't try and tune the AEM yourself. It's very powerful, but also complicated. Find a professional tuner to do it for you.

You don't absolutely have to use the AEM brand wideband. There are several others that work well. You can also choose the Innovative LM-1 and the Techedge WB. The Techedge is my favorite, but it caters to more technical people (it has more features than the LM-1). You can also buy the AEM WB separately from the EMS, they don't have to be bought together.

Popular masses believe in turbo timers, I don't. Turbo timers aren't necessary anymore. Any turbo that is oil and water cooled doesn't need one, especially if the oil drain is properly engineered. Turbo timers are just a waste of money and extra hassle.

Of course I will not be doing this myself. The person who will be doing this is my mechanic he looks like he knows what he is doing his tuned a few cars before not an AEM though it was on acel dfi and crome. I am not sure if it is the same as the aem. Hopefully I do not regret making him tune my setup. Does the techedge have to be specific to preludes?...Or can it be any WB I find?
If I let the car idle a few minutes before shut down will it do the same thing as the turbo timer?

There are a lot more features on the AEM than something like Crome. A better question to ask him is how long he has been tuning. If it is less than 2 years, find someone else. The AEM has lots of little things that work really well if you take the time to tune them.

The wideband is completely independent of any car. They are not specific to anything. You probably won't use the Techedge features, so you should go with the LM-1.

You could, but you don't need to. Coolant still circulates after the car is shut down. If the turbo is actually still hot enough, it will vaporize the coolant, and more will flow in to take it's place. Plus, most motor oils have very high flash points, and I'm not even sure the center cartridge of a turbo can get hot enough to burn it. That may have been true in the dark ages, but not true anymore.

He has been tuning cars for probably 3-4 years now. Are there any small features that should not be left out, in case he does not know about them or forgets them?...
Can you also give me an example of the many little things that work well...thx

There's no way I can sum it up for you in one post, too much info. Nearly all the bells & whistles can be found by reading the AEM forums. Off the top of my head:
1) Injector offset (great gains)
2) Gear dependant boost
3) Knock correction
4) More load points
5) IAT/coolant scaling
6) EGT correction

Lots of things to tweak. Most aren't necessary to mess with, but all of them yield mileage/power/drivability gains.

Sorry guys, I was on vacation ...
Anyway ... I am using AEM EMS with the AEM WB02 with AEM 3.5 BAr map sensor.
They all plug and play with eachother and it works very nicely.

AEM is way to complicated to even begin to do yourself, especially if you dont know anything about tuning. Pay a tuner and have it done correctly.
There are almost 2000 minute controlls within the system. The ones listed above are nice but the most important one is O2 feedback which allows the unit to re-tune itself depending on weather/temp/altitude conditions based off of O2 feedback while still keeping the original tune.

Many people that try to tune AEM by themselves cant even get the car started let alone running to a degree where they can start tuning.
