what is that and how they work

 

Hmmmmmmmmmm

Before anyone jumps on your case, I'll put out something kinda simple.

The ECU is the computer that controls the car.

The AEM EMS is an aftermarket computer that you can buy. It controls your car instead of your stock ECU. And it lets you tune your car.

I guess thats a quick definition.

 

Wow. just, wow.

 

Hey Porsche518. I guarantee you that I know more about cars, making them faster and driving them faster than you.


Wow. Just, wow.

 

why all the hostility. it's just a freakin question!!

ecu = preprogrammed settings from the factory for a/f ratios, timing, boost (if applicable), safety measures (ie. knock control, detonation, timing retard, etc) and adjustmeants for temperature, humidity and other conditions.

ems = continuously programmable engine management system where all settings are programmed by the user and are not adjusted except by the user. this enables whoever is using the system to alter settings for a particular driving style, condition or desired power output. It also includes extra features which are not necessary but are convenient such as automatic IC sprayer, 2step launch control, nitrous control, etc. it is a very versatile unit which you will never outgrow

 

Calm down there tiger. I meant no insult to the thread starter at all. I learned all i needed to learn about cars on a couple of beaters before jumping into an evo. Kinda strange that you own a high performance vehiecle such as an evo and not even know what an ECU is. So take your gaurentee, and keep it, i wont want to get my money back any time soon

 

My point wasn't the level of your car knowledge.

 

I really dont care what your point is. My point is this: go troll somewhere else.

 

yoyoyoyoyoyoyoyoyoyoyo's posts got me thinking, maybe we need to start an abbreviations thread on the new user forum.

 

I think the Q was funny cuz the poor guy could be under 16.

 

Haha, your 40 more posts than mine gives you so much credibility.

 

geeze guys.....simmer down

EMS: Engine Managment System

ECU: Engine Control System

I could be wrong but that is what I think they stand for

 

you're right but you meant Engine Control "unit"

BTW, I'm just giving the guy a hard time. No need to simmer.

 

all i know is that if you combine the two, you get "EMU". Sweet.

 

since everyone is being soooo friendly in here, you all can suck my knuts
