Rep Power: 307 how well does the aem ems work with k20's?
i noticed that the few boosted d17 guys using the aem ems 30-1030U have nothing but great things to say about it. but the 30-1030U is listed on dezods site to be compatible to k20a2 and a3 motors. I never really know what im going to do with my car, but if i were to invest in an ems, i think it would be a nice plus to have one that would be compatible with a potential future motor. (it would kinda make it feel like less of a waste of money) opinions? how does the aem ems do compared to the wonderful k-pro?

Rep Power: 272 Yeah dude get one, as long as you have someone who can tune it it would work out great. These computers are sick no doubt. If you were sure about the k20 if may be cheaper to go the k-pro route though. We were thinking about trying my EMS on my stock RSX Type-s to see if we could find some power somewhere, lol.

Rep Power: 326 The K Pro is definitely cheaper. But, I personally like the AEM, its a great system. I am sure it would work as well on a k20 as it does the d17. Its funny you mention this because if I ever get to a point where I decide that I want to swap a k series, I will already have the standalone for it.

Rep Power: 307 i know most k guys go with the hondata. I just want to make sure that if i decided to get the aem ems, that id be getting my moneys worth. im not sure that i'll go with a k20, but sometimes i tinker around with the idea of a s/c'ed k20a3. it's just nice to know that i'd have a nice computer capable of working with it all.

Rep Power: 379 i think im going to have to get AEM EMS or motec's ecus. kpro can't really handle the power up top. Kpro is a really easy direct swap for basic Engine set ups. but when you go over 600+ you need something with more options

Rep Power: 363 the best option for a K series is hondata kpro although there are select few running the AEM EMS as for tuning and capability they almost give the same options but I do not mean that word for word its just all in what you want to do with your carn/engine

Rep Power: 307 ^i really doubt that a $1300 standalone unit isnt equiped with some type of non-volatile memory. Because I know i can unplug my $300 emanage and not worry about losing my maps.
you guys really sold me on this thing. Looks like i have something else to save up for...

Rep Power: 272 I have completely unplugged and removed my AEM during the whole winter in case someone decided to try and swipe something from my car, I plugged it in and fired it right up. If I were spending the money, AEM all the way. You really can adapt almost anything to your setup.

Rep Power: 233 Well only thing about AEM that i have herd on k20a.org is that if you use a AEM EMS on ur k series that u lose some stuff like cruse and there was someother thigns but i 4 got thats the main thing people were talking about.. but i guess that if AEM is an all around better ECU then for that small thing its not a big deal.

Rep Power: 326 Well even the immobilizer is an independent computer. The ecu only provides juice to these other computers. Even someone who's running a 1070 without a stock ecu has all functions that a stock car would, except a/c and coolant temp gauge.
And you don't have to splice the wires, the ems comes with the adapter harness for the stock ecu to plug right in. No wiring necessary.

Rep Power: 226 Kpro should NEVER be affected when you unplug anything, it reprograms the entire ECU. I would say that Kpro is way better for the simple reason that most tuners are better with kpro, and you can do anything you would ever want.

Rep Power: 0 Well its been a while that I have posted here anyways I have had my built D17 running on the AEM EMS from the starting and it was a remarkable system for the D17, then I switched to the K series and I must say that the EMS is the real deal for the K series engine. I have only one complaint with the EMS for the K series and that is the fact that when starting, the engine has to make 2 complete reveloutions for the "stat sync" to turn on therefore the car takes about 1.5 seconds to start. Most people are using the KPro because it cost less and its a basic system for the K series, the K Pro's 2 step rev limiter also does not work very well with the K series engines. It also does not have traction control, automapping, being able to control each cylinder individually etc. There are lots of added features of running the EMS, however it cost more than KPro. Also the way the EMS is programed for the K series engines is also different to how KPro is setup e.g the cam angle maps in KPro is set at 0 degrees which increases to 50 degrees full advance. In the EMS it is the other way around eg. 50 degrees then increases to 0 degrees which is full advance. All in all I have not regretted getting the EMS, every last penny worth it.
If you have a "PRC" ecu from the JDM K20A that has been KPro'ed then you cannot control nitrous. The KPro is a basic system, remember you get what you pay for!!!!!!!

Rep Power: 272 I have the same deal with my d17 with the EMS, feels like forever when you start it. I wait till after my car starts beeping then crank it over. Otherwise it will crank a few times before firing off.
