3 rotor motor, best(easiest) ecu to use?
 

Mint 3rd gen blown motor, mint 3 rotor on floor, the next step just seems to make sense. i have no ecu or harness for the 3 rotor. Anybody, done this already? Best ecu for the job and why?? Thanks

Lots of options. I'd say the computer is a lot of the complexity of the install/tune, but the other major chore is the fitting of the engine.

Being in Canada, it may not matter as much if you don't run split timing. So, you could use a Haltech E6K for a cheap alternative with decent amount of support through Hitman.

Microtech has history of running 20B engines in street and race form.

AEM is a very flexible ECU for the bucks. I'm not sure how much support you'll get since I haven't heard of anybody running a 20B with an AEM.

I'd try Electromotive, you can call them or PFSupercars about it, they have setups for it, here are the websites:

I'm running E6K and I haven't had any problems with it.

I herd that the E11 is a little harder to program but still one of the best system.


Or if you really want a good system and money isn't a problem try MoTeC. http://www.motec.com.au

Why don't you go to the 20B section of this forum and do a search. We have rehashed this subject waaay too many times already.

People are generally running Motec, TEC I or TEC 3 (what I'm using. Call Fred at Electromotive for help and/or questions), Haltech E11, Wolf 3D 4.0. Microtech and others seem to be better for WOT only and aren't very good for street use so the discussions have went.

No, just the Microtech computers have coarse fuel injector resolution (0.05 mS) which is best left to WOT drag racing or non-turbo engines. The newer Microtech computers may have fixed this, but no data has been published to my knowledge. The Haltech E11 and Wolf3D 4.0 both have fantastic 0.004 mS injector resolution, which I believe is superior to that of the TEC3.

TEC3's Max Resolution for fuel injectors is .001 mS. Ignition is 1/4 deg at worst case also.

I'd be interested in knowing who said the E11 is more diffucult and why.

I haven't seen it but thats what haltech in Aus told me. I guess a few people have had a little trouble with it. But I am planning on getting me an e11 for my car and giving the e6k to my brother.

I'm going to take a guess based on my experience with Wolf. It's probably due to the increased resolution and options. The old Wolf3D 3.0 was pretty simple to use with only 8 load bands and rpm points every 500 rpm = 128 points to tune per fuel or ignition map on an 8,000rpm engine. The new Wolf3D 4.0 with 16 load bands and rpm points every 125 rpm = 1024 points on the same 8,000rpm engine. That equates to 8 times the work, not including all the extra trims and other options that the newer EMS products like the Wolf3D 4.0 have now. The E11 has even more confusing and time-consuming options than the Wolf3D 4.0, so I would imagine that this is where the added difficulty comes in.

It would be nice to hear from those one or two unbiased E11 owners to see what they think of the new system.

i was just gonna say that! dont forget you have a new interface to learn
