Does anyone know if the autronic with the multiplexer runs split timing and is anyone running one?

 

Yes the Autronic SM-4 with multiplexer runs 20B with split timing no problems.

 

one question answered anyone running one?

 

I will soon be running Autronic in my 20B. I know it's not running like you asked for but in another forum someone mentioned that at Sema Autronic had 2 20B's running Autronic. It should be installed in 3 weeks so if u don't get any answers i'll let u know how it went.

 

Would like to know what you think after the tune is complete. Im debating between the halltech and the autronic and I feel the autronic may be the better unit.

 

Abiex is running it on his car, but it is not completely dialed in yet. You can fully map split timing using the sm4. The multiplexer converts 4 channels into 6 by activating addition channels by firing the fourth coil in parallel with the others. Sounds kind of odd, but this is apparently not a big deal from an electronics standpoint.

The one feature I wish it had was traction control. In another thread someone mentioned that it has the capacity to run it, but the resources are used by default for VVT. Hopefully some day it will be an option.

As it is I think the sm4 is the best option under $3,000 for a 20B.

 

I guess I was under the impression it had traction control.

 

The SM2 had traction control, but it was removed on the SM4. There was a rumor floating around that a future version would have features of the SM4 plus traction control... but no idea when or if that might really become available.

 

I would say the Universal AEM EMS is the best option under $3000. Everything works on it, including timiong split, traction control, upto 4 EGTs, etc . It is VERY NICE. No need for multiplexers etc.

 

No need for a multiplexer, but I believe even the universal like the plug and play has only 5 ignition outputs and converting one of the other channels into a 6th doesn't sound like a cake walk!

They also have a pretty abysmal track record of reliability.

If you do a search you will see that I once owned an AEM ems, ignition amp, and wide band. I couldn't get the ecu to pickup timing on my 2 rotor, tried to update the firmware with Jason from AEM on the phone with me and the ecu crashed and was completely unresponsive from that point on. AEM sent me new chips to insert into the board (DIY warranty work??), but at that point I decided I did not want to risk my motor on something so temperamental. I also went through two different versions of their ignition boxes before they kindly agreed to refund my money.

Don't get me wrong, I certainly see the benefits on paper (low price with every feature I can imagine), but given the cost of a 20b engine and turbo and the company's spotty track record I think are better options out there.

That's the problem...
It doesn't work.

The 5 channel is no big deal, it has been done successfully.
I know a lot of people had issues with AEM EMS in the beginning, but in the last 2-3 years, their are products are really good. I tune many cars on the dyno, and in teh last 3 years, I have seen only one bad Supra box, and they replaced it in 3 days.
The software is really complicated, so it is not for a first time user. But it is really powerful. I do AEM tuning every day, so I am familiar with most of it. All of our AEM customers are EXTREMELY happy.
The E11V2 is another good option. The SM4 is good ( that is what everybody says), but not many people run it as of yet, so not much feedback. Also, the lack of traction control kinda disappoints the people.

REted: It ACTUALLY works REALLY GOOD. I use the AEM EMS every day. I do not listen what some newbies tell me about a standalone, I just look into it really close, and decide on my own. I know you have vast expeience with HAltech, how would you feel if somebody that has almost no experience with it, tells you that Haltech E11V2 sucks.

Everybody has an opinion. But facts are facts: The AEM EMS is one of the best ECUs out there. Again, it is not for first time user that plugs it in and tries to tune his car with a boost gauge, and an Autometer afr gauge.

Just my 2cents...

 

Sure...
If you own a Supra or a Honda, no problem.
It is just not reliable on an FD or on a 20B application.
Just look at all the problems in the AEM section?
Last time I heard, AEM has not fixed all those problems.

What about their CDI box?
Still got lots of problems with those.

MoTeC

 

:rollseyes:

I actually spoke to my local Motec dealer. You know what he said?

GET AUTRONIC, don't waste your money on motec.

Autronic ECU's are top notch. They may not have this super brand recognition that Motec has, but the quality is right up there and for a fraction of the price. It *may* have a few additional features, but at what cost? Based on my conversations with vendors for application in a steet based car the Motec offers nothing that I need and something that I don't want: additional cost.

NOT saying that Motec's are bad. But they are NOT the solution to everything.

-Chris

 

One thing I noticed is that Motec uses a 32-bit processor whereas the SM4 has a 20mhz 16-bit processor. In another thread someone mentioned that the founder of Autronics was one of the people responsible for developing the M4,M48, M8, yet he used an inferior chip for the Autronic SM ECU series. I wonder what the motive was behind that decision -lack of a benefit, lower cost ???

I really like the MX00 series ECUs from Motec -the software is very easy to use and extremely versitle. However, it is hard to justify spending 2x + the cost of the SM4 for only marginal better functionality.

 

Yes, Motec is really nice.

Today for the first time I played with a SM4 on a Subaru WRX. The car is going on the dyno tomorrow. So far, everything is ok. It is different than the SMC and SM2, but I am not sure yet if it is worth the extra $1000. In a 20B car, my main concern would be split timing, and traction control. It does not offer the traction control:-( But otherwise it is better than the other Autronic ECUs.

 

Ted, you have to agree with me that most problems with standalones happen because the user does not know how to wire and tune them.
AEM did fix their bugs. Not only they did that, but they warranty any claim. That is some very good customer support.
No standalone is perfect. Haltech had issues with walking timing, and fixed it. Autronic had issues with loosing cam signal on 4G63 while driving. The Power FC for the 1995-99 eclipse doe snot work on certain cars from 1995. Autronic had some issues with pins coming out of the harness while you drive. Microtech send a box for the MS Protege, that would actually walk timing by a lot - 40-50 degrees up and down, for no reason, or stay perfect for a while. How do I know all that? I had to troubleshoot all these issues. And the list goes on.
The fact is that the companies take care of their mistakes.
On the factory ECU on the car is pretty much bulletproof and tested. OK, I take that back - my wifes 2005 Corolla used to die while driving only sometimes. Toyota messed up the first year of DBW ecus for the Corolla and Matrix. Does Toyota suck? No, they fixed the problem, although it took 4 trips to the dealership.
I hope you are getting my point here...

Several high HP 20Bs are running the AEM, and many 13B run it too. Many shops do customers cars, and never post their positive experience with it. Only the bad stuff goes online.

 

When working at the scca events here locally I can only notice that the formula mazda race cars have motec beacons on them. I don't see any that say autronic. Wonder why?

-Destin

 

Yes. You never hear about MoTeC's ****** up. They dont get hot and shut off. they dont randomly drop maps. they dont burn out injector drivers. they dont lose cam signal. they don't have timing issues. Willl I spend the extra money on a quality ECU to protect my investment in my car? you bet your *** I will. You have to pay to play. Bottom line: you get what you pay for. That's it.

 

Motec and AEM are on top of everything...

 

I will not get into an argument about this, because all the proof is in the AEM subsection in here.


This was all started by your comments...
"I would say the Universal AEM EMS is the best option under $3000."
I would easily pick Autronic over an AEM anyday, thus, my comments in this thread.
I never claimed any of the other brands are perfect either.
People who know me know that I push Haltech - I've never claimed Haltech to be the best.


-Ted

 

This is all personal opinion. You go buy what people post on the forums, I go by experience. And I have enough experience with both.

The Autronic works really good, it just takes longer to setup and tune. That is all. And I hate it when the F1 button brings out the TBA message, instead of some help...

Lets leave all that on the side.
Have you seen the E11V2 run on a RB26DETT? Any issues?

 

Would love to have the motec but WOW that thing is made of gold and cant afford it. The options I have are the autronic or the halltech e11. I lean towards the Halltech because Im no tuner and I can get a pretty good map to get me going before Kan tunes the car.
anyone tell me the advantages or disadvantages between the two?



Looks like a motec with options is around 4000+ Is that right?

 

At lest and easily more.
