I really don't know who you were talking to at Electromotive. But, I would be the house on it, that it will run it. Even if takes little work setting things up. Because the TEC3 does have 6 waiste spark ignition drivers. Which you ground one of each coil tower out for direct fire. TEC3 has individual coil trims, with be enough for do the split.

The normal TEC3 will not control a 3 rotor, it will control a 2 rotor pretty nicely.

You have to order the special TEC3 the TEC3 6/12 version. Because I think it loses 2 injector drivers to add the over two ignition drivers for runing 6 coil packs.

 

too bad, then i guess running it like a 2 rotor with 180* timming wouldn't matter.. Send me that stuff later, i would like to read up on it

i believe anthony at maztech has a FD 20B running quite nicely with none of the afore mentioned problems associated with haltech and co.

Wouldn't it be wiser to speak to the man with regard to the ecu's capabilities rather than going from hearsay. It could be a relatively simple to solution to your problem.

Not trying to start the microtech V's rest of the world thing again, but just offering an option.

I have an MTX8L on my FD and have never had timing scatter as an issue.

 

Just got off the phone with Electromotive, talked to James. This time they said that it WILL run the split based on RPM... I dunno what's up with the first answer that I got, but I guess it was wrong.

 

007007: Thanks for your input, I am just chosing to not use a Microtech. I'm glad you have had good luck with it. I feel the AEM or the TEC III is where i'm heading, just trying to narrow it down.... If the AEM race ECU was available, I'd be picking it up... but the TEC III is not vaporware... oh well, this is for a bit later in the winter anyhow, just trying to decide what I want to do.

 

me too here's how i see things

haltech e6k:
doesnt compensate for different temps very well
anything thats crimped on the harness is junk
it doesn't do split or sequential injection

autronic:
has a self tuning that works
it doesnt do split on a 3 rotor, but it looks like it does the injection
its about 2k for everything

tec3;
its harder to setup than the haltech, and more money

micro-tech: its all in the name =), i dare you to start the car cold and have it run ok

motec: i dont really know anything about it

stock ecu: it has everything except adjustablity, oh and the afm

e11: when haltech usa knows that it exists, it might be worth a look

power fc: the skyline one would work. it would actually start the car hot an cold, has the most potential, if you have the power excel software.....

mike

 

Mike, what do you think about the AEM? Sounds promising to me....

I refuse to buy the E11, not gonna happen.

The PFC sounds intriguing... do you have a source to get the skyline PFC? Any clue how much it would cost? Do they have the same 17 psi boost limit that I've seen people complain about with their FD and the PFC?

Speaking of power excel software... is it "easy" to come by? I heard someone hacked the serial comunication and made their own datalogging software or something, or maybe the excel software just leaked... who knows... anyone?

 

i think the aem would be fine, but i dunno much about it.

i dunno what kind of map sensor the stock skylines have, if they have 3 bar, your cool. i think motorex sells them (i havent really looked that far), the fd power fc would work if you could change the firing order.
the datalogit is pretty cool, you tell it what afr you want make a run and it tells you what cells to change.
the power excel stuff, as far as i know, nobody but xs and sr have. if you could change the firing order in the fd power fc, it would plug into an s5 car, and the 20b engine harness

mike

 

Well, strike 1, 2, and 3... I don't have the 20B wiring harness. I don't have my S5 Wiring harness, and I'm pretty sure the skyling comes with a lower map sensor. I remember someone complaining about it for some reason....

I'm thinking AEM, when available...

 

its time to think outside the box
http://www.marelli.it/racing/products.htm#11
bocsh makes f1 stuff too right? those are v10's and 12's
right?

mike

 

The prob with the PFC running 17psi isnt the computer its the stock map sensor. It can be replaced with a 3bar GM map sensor.

Also, with the Datalogit you dont need a excel dealer, they are a waste of time. You can control and see everything with the Datalogit. Its a awsome tool in conjunction with a PFC.

Like you said the AEM sounds good too.

STEPHEN

 

You ever set a TECII or TEC3 up? It is the easiest system out there. You plug in you specs of your engine in the Tuning Wizard and it will make a nice base map that will start you engine. Ajusted out you Idle stuff get nice stable Idle, take the car out and drive it, it AUTOTUNE mode, to get your drivablity done. Then stick it on the dyno and tune out your full throttle underboost maps.


Also with the TEC3 your not just buying a ECU, your buying a top of the line Ignition system.

Only Haltech I have played with is the E6K and the TECII and 3 was much easy to tune and setup than the E6K TOO ME that is. Maybe other people can chime in this.

On the AEM, I have been playing with a AEM plug and play on DSM. That thing is nightmare to tune. Maybe its where I am used to Electromotive products. I wouldn't wish a AEM system on anyone. Maybe I can't tune it. But I have exp with Electromotive systems, Haltechs, Link systems, and SDS ECUs. I know those systems pretty well. The AEM was nightmare for me to get the car runing half way decent.

But I am also new to tuning Rotary engines. 95% of my exp come off of piston engines.

 

yah the more i look the tecs look nice, maybe i'll just get a weber....

mike

 

hmmmmm, Tec III.... It's not vaporware... it has SOME support... and it's not Haltech. If the AEM race ECU was available.... mabye I'd go with that. But, that is a good point... the Tec III is also a top of the line iginition system... hmmm, so many options....

 

God it is funny what some people come up with, once cold start is TUNED the car will start and run fine when cold,

its funny how most people on this forum have had nothing to do with it at all and say all this stuff about it,
its sad that a few people have had no luck with it and all of a sudden its the worst ECU in the world,
The fact that it runs the 3 fastest 20b's in the world and 80% of rotor street cars in AUS means nothing.

Dale

 

The EMS DualSport Type R
www.fuel-injection.com
Can do 20b with split. I've been using one for about a year now. Split is adjustable to the nearest 0.2degrees.

 

I have one, and I can tell you for certain that it does NOT run split-timing on a 3-rotor. However, it does have better 2-rotor split timing than the 3.0, and is a very nice EMS. I do not need to pass emissions here in Florida, so split timing is a non-issue for me. I can also tell you for sure that the current M800 will not run 3-rotor split timing, either. That should tell you how much the pros care about 3-rotor or 4-rotor split timing.

Quick explanation: The fuel/air mixture can sit in the bottom of the intake runner for a second without any significant ill effects. You could activate all the injectors at the same time (this is called batch injection) and the engine will still work just fine, although sequential injection is a little more efficient. The ignition timing for the rotors, however, is 120deg apart on the 20B, and really bad things will happen if you introduce a waste spark every 180deg. The 2-rotor engine can work with 180deg waste spark because the rotors are phased 180deg, and the waste spark can't cause any damage because the fuel/air mixture of the waste spark rotor is not exposed at this point.

You have a 20B?

The specs sheet on that EMS says that it only has 4 ignition outputs, which will allow for split timing of a 2-rotor with appropriate software. However, 3-rotor split timing requires 6 ignition outputs. Does that "Type R" model have 6 ignition outputs, or are 2 of the aux outputs used for this?

 

Ahh I see.. Only on the 2 rotor, oh well it was a shot in the dark.

 

we saw one or two at seven stock, and either people dont know how to tune, or the ecu wont run the car cold. and the fact that it runs the 3 fastest 20bs in the world does mean nothing.

There is a difference between tuning a car for WOT drag racing and having a street or road race car. The microtech can handle the drag racing fine, but the tuning resolution on them is not what I would call substantial. I don't know what the resolution is any more, but when I was doing research on an ECU to buy, I remember placing the microtech just about the Link system, link was at the bottom.

 

I'd have to agree, fast at WOT and street tunning are 2 different things..

That is why in puerto rico they have so many fast carbed/turbo cars.. But i doubt you would want to drive them on the street everyday..


-Zach

 

Like i said guys not trying to start the microtech V's the rest of the world thing again, but i think the tuning capabilities/knowledge of some of the guys over there are discrediting the microtech to a certain extent. I also acknowledge that the resolution of the microtech is not as good as some of the higher end EMS's but with capable tuning it is certainly livable.

Like i said i have had an MTX8 on my FD for coming on two years now and in that time i have had the opportunity to go with other systems. I did not see that there was a need. Prior to the car being ported and having the single fitted i am sure most people would have assumed it had the standard ecu.

As for the cold start problem that is a crock. I can put my hand through the window and start my car and walk away, never having revved it. By the way it doesn't stall. Like i said it tends to point to the capabilities of the people using the computer.

 

please lest not start the micro tech vs everyone else thing again, it always boils out the same. maybe in austrailia it works better, because you have plenty of people using it, here its not very common.
i have some of the same beefs with the haltechs too, so this isnt a "i hate micro tech" its more like "this is my opinion based on what ive seen, in person"

mike

 

Don't get the AEM! People are having problems with it (AEM's fault not user/installers fault).

 

i appreciate what you are saying j9fd3s i am just stating that the perceived "faults/inadequacies" being mentioned can mostly be attributed to unfamiliarity with the system.
