I hear a lot of back and forth talk about the E6k, and Microtech and a few others but dont know which to choose. I've searched and havent seen too much besides half witted sales pitches. Im not asking what is better or anything like that, i just want to know what would be a nice system to get. Should i go with the E6k (which i heard is getting outdated), a Microtech (ltx8 or ltx12). I also heard about the Haltech E11, but i dont know anything about that. I havent heard of that wolf system either for that matter. I know, well, so ive heard, that the Motec system is the best, and also the most expensive(how much is it). Since im not Shumacher, and i doubt i will be going to Tsukuba anytime soon, i dont think that the Motec EMS would be neccesary. Laptop support is a plus, and Normal PC tuning is as well. Im not too sure about what a lot of the EMS termanology accounts for (open/closed loops, etc). This will be used for my FC(turbo). I do like the idea of the Haltech's ability to be tuned while running, but i dont know for sure if any of the others have this same option. I'm not a fan of the whole extra gauge type attachments that you can get with the Microtech, im sure they do their job well, but i just wouldnt like all that too much. I plan on having the car re-wired as well, and from what i've heard, i can get rid of a lot of unneccessary engine components with the EMS. If you can provide me with as much information as possible, that would be a great help. It has also been brought to my attention to use water injection, or someother type of injection. Do these systems all compensate for this? Prices on the systems (e6k ~1200, ltx8 ~900, ltx12 ~1000) i dont know how much the Motec, Wolf, or E11 are, or maybe other systems. I have also recently looked at Greddy's new E manage piggy back system which is supposed to perform quite well, while i do not have any personal experience with it. Thanks

They are all good in their own way. The E6K works just fine, and was only superseded by the E11 about 6 months ago. I don't think you would need the extra cylinder/rotor control of the Microtech LTX-12, as the LTX-8 will work just fine for your 2-rotor engine. If you want to keep your stock coils, you can use the less-expensive LT-8.

About $2K - 10K, depending on what you get. The catalog on the US website has pricing information.

Just about every EMS has "laptop" tuning, which means that you can use a PC if you are tuning on a dyno and have the PC hooked up in the garage, or if you have a really long extension cord, lol. Most EMS software allows for offline tuning so you can adjust your maps from a PC or laptop without having it hooked up to your engine, but this obviously has limitations as you will not be able to see the results of your tuning until you load the program into the EMS and run the engine. Some EMS products offer a hand controller so you can tune without a laptop or PC.

Closed loop means that the EMS uses O2 sensor readings to maintain a given air-fuel ratio. This is really only good for very stable engine operation like cruise and idle, so most performance enthusiasts don't even bother with this function even if the EMS has the capability. Open loop means that the EMS doesn't use the O2 sensor to compute the fuel requirements, but rather uses pre-set data as determined by the tuner, which is how most performance engines are run.

Almost all of them do this. You need to research some more. We do have an ECU forum here:

All that stuff is just optional.

I agree. Most tuners will offer you a good purchase/installation/tuning package, which is almost always a better deal than if you buy the EMS separately and then go to the tuner for installation and/or tuning. Always check with the sales representative before buying an EMS to make sure that it can do what you want, and to verify what you need to buy and how much it will cost.

Look for the "Dealers" link at the various EMS websites, and also ask in your regional forum:
