What Stand Alone is best for 20b?
I am curious which stand alone ems do you consider to be the best for the 20b? For me price doesnt matter as much as user friendliness and tuneability.

The best EMS is the MoTeC M880, and Roger Mandeville is the best MoTeC dealer for anybody with a rotary engine.

From my experience they are all very good.
I have spent a little time working in shops that do tuning and generally found that whoever it is doing the tuning should chose whichever ECU they are most comfortable with. As long as the ECU has the required number of drivers to run the 20B and enough outputs to suit any additional functions, then it all comes down to the actual tune. An A/F of 12 is the same whether it is coming from injectors fired by a MoTeC or a Microtech. The only real exception here is if the resolution is too large to accurately tune with enormous injectors. Cheers, Sam. |

I don't remember it as being that user friendly though. The Autronics ecu is also very good.
While Autronic does produce quality systems, the US dealers will not sell any of their products unless their own technicians perform the installation, the company threatens automotive websites which host discussions of their products, and it has been my experience that the company is generally not very friendly to the rotary engine novice community. While this is not a good do-it-yourself EMS brand, there are some good Autronic dealers/tuners on this forum who will most assuredly install a top-notch system in your car. MoTeC has a long record of running record-setting rotary engines at the top tier of auto racing, and their support team has helped me a great deal with my car even though I do not own a MoTeC EMS.

David Hayes and I are using the Microtech TX12.

An A/F of 12 is the same whether it is coming from injectors fired by a MoTeC or a Microtech. The only real exception here is if the resolution is too large to accurately tune with enormous injectors. a combo of 1600cc & 2400cc would be an awful mix for a street car (unless it runs e85+).. i think its all purpose-based on this topic. but from your overall post - you're saying "an ecu is an ecu, everything else is in the tune". while that statement is correct to some degree, it really fails over all. if a standalone is a standalone (all the same) then I could have saved myself $4k - but not everything is equal in this dept. |
If money is not an issue, I would go with motec. If is going to a 20B a Motec M600 would do the work just fine, you'll have all the advantage of ignition timing split. We have work with several motec's in Puerto Rico, see us at http://www.aponteracing.com.

Ok, first of all I'm not here to try and suggest that a MoTeC is the same as a Microtech - I have a MoTeC running one of my engines!! however, the question was very unspecific in asking what is the 'best'... best for features? best for resolution? best for processor speed? best value.........????

wrong - if the cpu inside the ECU (powerfc for example) is on the slower side then things like logging (rate), etc suffer. other things like "quality" come into play here too. not all coil (ign & injector) drivers are the same.. My main point here was that in a street car (not an out and out race car chasing tenths of a second) it is nigh on impossible to tell what kind of ECU is running the engine whilst driving it and nearly as hard on the dyno... Thus the most important point being that the tuner is familiar enough with the chosen ECU to be able to get the most out of it. I have seen some big dollar ECU equipped cars drive like rubbish and others with very, very cheap home brand style ECUs drive like magic all because the tuner was very familiar with it and able to get the most out of it.

I think you guys say MoTec because of the $$$.
The hardware of the M800 isn't all that great & the software isn't anything to boast about. On top of that, the enabled standard options/features is pretty low and god damn costly to enable... There are better/faster/stronger computers but we're really looking at a whole other level of computers. Back on topic, I've had a lot of success with AEM's... hardware isn't fancy but it'll stomp a mud hole in just about any other ECU in its price range (lb for lb). |
i would say that autronic would be your best bet.. Not only is it cheaper than systems it compairs to (such as motec or EFI technology) but it has more to offer, such as autotune, and a lot of experienced rotary tuners.
|
Motecs are soo expensive...i run a Microtech LT-16..
|
I like the AEM & Wolf3D for a cheaper.
FAST/EFI would be in there also (does real time calculation opposed to the above mentioned ecus which only do a simple table look-up). Pi / Pectel remains my most fav ecu company of all time. |
For funtions and ease of use per dollar you cannot beat Microtech. They are used on many of the fastest drag rotaries in the world including /eddie Colon's 6 second world record car. Motec is great stuff but hyper expensive and does not use many of the factory sensors as the Microtech does. Motec is mostly used by the big budget roadcourse racers.

what about the haltech e11 or platinum or even electromotive tech gt.. where these 2 takes care of the waste spark.. so you have sequential spark..

Have you considered the link ecu's?
http://www.linkecu.com/products/engi...ecus/g4-xtreme Not sure how popular they are in america. I sold my microtech to go with a link g4 storm on my 13b jc. I plan on running the link g4 extreme on my 20b jc. I don't have much experience with ecu's, i wired this in myself and road tuned it. I think they're preferred over microtech's here in NZ. Great value and so many more options you can fiddle with. You can atleast download the software to have a look for yourself: http://www.linkecu.com/support/dland...Link-downloads This local rb30 240z is seeing good results running a link g4, he's into the 7's now. There's other articles around on the net: http://www.ripsltd.com/RIPS-in-print/articles5.html Oh and one thing i love about this ecu, unsure if others have this option. You fill out a map of target a/f ratio's, go for a drive in your car, hold the car at certain rpm and load points, and the computer will modify it's map to correct it's a/f ratio. You can specify how accurate the computer is with this road rolling tuning, you can specify to go within whatever decimal accurateness, how long you must spend in a tables cell (to allow the wideband time to react, etc), and a few other options. |
I don't understand the comment on Haltech or electromotive. The microtech, and all of the others that I know of, fire the secondary plugs.
