I just sold my E6K and have purchased an Autronic SM2 and CDI ignition unit. Is anyone else running the Autronic system?

I hear nothing but good about it.

 

I have the whole Autronic line-up now. I bought the wideband this summer, and now just picked up a SM2 and 500R CDI unit. The dealer I bought from also hooked me up with a M&W dual-post coilpack and two single-post coilpacks for the trailing. So, I will have a brand spanking new ignition system.

I also am switching from 550 primaries to 1600. I will have 1600s in the secondary also. How does the SM2 handle the big 1600s on the primary. I am assuming that they will have to be run around 1ms at idle? That's friggin low. Also, what base fuel pressure is required to push the fuel through at that low of a duty cycle?

Any base start-up CAL files out there for the stock CAS and the 1600s all around?

 

member enzo250 is using a SM2 on his T2 with great results. PM him if you have any set-up/tuning questions

I should have the CDI and the ECU by real early next week.

 

Anyone have a CAL file I can play with? I have the software but no CAL file, so I really cannot do much with the software.

 

Great choice... I recommend using four of the same size injectors with the autronic. You shouldn't have any problems whatsoever with four 1600cc's. You will be amazed on how well the autronic will control large injectors. I like to use about 40~45psi fuel pressure.

Which injectors are you using? The Bosch 839's are very good and have very fast response.

The 500R is very powerful. It will provide plenty of spark no matter how much fuel you throw at it.
I have some .cal files to help you out.
I can also help you out with the wiring. It can be a little tricky.

Thanks Enzo for the response. I wired the Haltech myself and had no issues. I also am helping a friend of mine do his Haltech on a TII. He did not want to poney up for an SM2, so I made him a good deal on my E6K. I am glad to move on to Autronic.

I may need some insight on wiring the crank triggers to the external reluctor adapter. I will have to meter out the TPS to figure out which wires are which, but that's no big deal. I plan to use the stock Mazda coolant sensor and of course the Autronic air-temp sensor.

We need to get more info on this Forum related to rotaries and Autronic. I PMed the moderator and requested an Autronic section. I thinkwe are few and far between on this Forum.

I am glad to hear that the CDI box will yield the results that I am looking for. I would like to run 10.8:1 under boost to be safe after loosing two engines last year. I'll take a little cut in HP to save an engine. The stock ignition would start puking out at those Lambdas.

My email address is zkeller@gettle.com if you would be kind enough to shoot those .CAL files over!

Thanks, Zach

 

Oh yea, the injectors are the ones that most people seam to be using. They have the aqua color connector base. I think they are the injectors that GM used on the 80 something turbo charged Firebird?

 

You just can't do that...

Hey Ted,

Im not gonna start another heated discussion. BUT.
Try it and you'll see how, And don't say you can't until you've tried!

 

Okay, you're telling me the Autronic can run the pulsewidth down to 1.x ms and still shoot out fuel and be stable?  That's like counter to the laws of physics - almost every other EMS out there cannot idle down past 1.8ms to 2.0ms without running into some serious stability issues.  We're talking about pulsewidths under 3%?  Do you know what Autronics does to get their EMS's to do this?

This is not a flame either - I'm just curious to know how this is possible?

A local audi is using 5x1600 injectors, and there's no problem with the idle. The autronic's have awesome injectordrivers.

 

Autronic is well known in the industry for their injector control.

Even with my EE Degree, I have no idea how the autronic does what it does. But it can and does many things that amaze me.

It has to do with their injector drivers and software.
When the Autronic is told that it will be controlling a certain type of injector, it then employs a specific injector firing strategy to handle those particular injectors. The Autronic software has an extensive library of injector types that have been tested, and even allows a user defined function if someone has the equipment and ability to test their own injectors. Otherwise you'll have to send them out for testing.

Bosch makes a very fast 160lb injector(280 150 839, blue top).

 

good to see another autronic/rotary user!
i can send off a base map cas file if you still need one. if your planning on using the factory coolant sensor for the dash instrument display you will need to have a seperate temp sensor for the sm2 as there can be problems sharing. i can also lend a hand with wiring.

i'm running 4 crude (apparently) rochestor 1000cc inj at 40psi and she idles sweet at 800rpm.

 

I run it too, great little system.

Support can be a hassel, but your in good hands with Enzo and Bern, I can help a bit too if your stuck

 

I was shocked to find that the four-spot 1600cc setup was actually RECOMMENDED when I checked to make sure that Zach wouldn't have problems doing this. It'll be interesting to see what results he gets, and what kind of improvement he'll get over the E6K that he took out.

Keep us posted. . .

13BAce ran 4X1600cc injectors on his 13BT with a Wolf3D V3. I don't think that anybody here will accuse the old V3 Wolf of having any fancy injector drivers or databases, so I am not totally convinced that this makes the difference.

 

ORX705: Enzo was going to send me a base CAL file when he gets a chance, but if you have one please email it to me at zkeller@gettle.com. I am anxious to tinker with the software until I get the equipment.

By the way, the FD uses a seperate, single-wire sensor for the gauge. It is located near the oil filter. The coolant temp sensor, 2-wire, is just an input for the ECU. There is also another sensor located below the coolant temp sensor, single wire, actually a thermoswitch for just the cooling fans. It's part of the complicated cooling fan system.

Thanks for the help as I venture into the relm of a new EMS!

 

Hey Ted, I think that Enzo told me that they fire the secondaries with the primaries, or the secondaries fire before the primaries?? Enzo, can you correct me here? I had the same question as you Ted. How in the hell can an EMS control an injector at 3% of its duty cycle?

how much did you gentlemen spend on this system?

 

the price for the autronic wideband ?

 

could you please mail me a base .cal file to?? I'm getting the system in a couple of weeks too! Is more or less the only thing left!

frode@mazdaracing.net

 

oops, doesnt work...

frode@kjodalf.net is the one.

 

PM or e'mail either Enzo or myself off the list for pricing.
