Ok so i need to get a EMS, because i just popped a motor, and would like to know which one and why? The wolf is cheaper from what i have seen, but does it serve as many functions as the Haltech...i.e Nitrous, thermo fan, anti lag, turbo timer function......so and so forth. For some reason i can't open the wolf web site. Any help is appreciated. thanks.

 

The Wolf3D 3.x is no longer in production, as it has been replaced with the new Version 4.0. Here is a link to the new web site:
http://www.wolfems.com.au/wolf_3d_page.html

I have one of the few Wolf3D 4.0 EMS units in the USA, but I am still waiting on some components before I can try tuning an engine. The Wolf has a dedicated output for a thermo fan and one for rpm-based boost control (every 125rpm from 0-16,000rpm), as well as a turbo timer option. There are two outputs/input leads which can be configured for things like nitrous. The Wolf does not have a dedicated anti-lag function, but you can trim the deceleration enleanment rate and decay values, as well as fuel cut over-run. The new 4.0 manuals have some typos, but it appears that there is also an ignition off-throttle trim function. I'm not sure if the difference matters much in the real world, but the Wolf has better rpm resolution when compared to the Haltech E6K (every 125rpm from 0-16,000rpm vs. 500rpm from 0-10,500 & 1000rpm from 10,500-16,000), but less load bands (16 vs. 22/17). The Wolf has a rotary trail pulse feature for 1-2 rotor engines, but it is not adjustable for rpm or load.

Unfortunately, the new Wolf3D 4.0 does not have a datalogging function on the hand controller like its predecessor. Therefore, datalogging may only be performed with a laptop sitting in the passenger seat, so the new unit is of little value to those whose cars live on the race track. You can still program most functions of the EMS through the hand controller, but it is generally not practical for tuning because of the increased resolution and the lack of datalogging. Fortunately, the excellent memory cartridge feature is still retained, which allows swapping pre-made EMS maps in a matter of seconds without the need for a laptop. The Wolf software is really nice, but it comes with a horrible copy protection which only allows you to install it once, and then you must contact Australia for a new password if you need to reload it.

The Wolf3D 4.0 will sell for about the same price as a Haltech E6K.

 

They are both 2 of the best EMS out there for a rotary engine. Basically what should make your decision is availability to tuner shops and people who can help you out with it. In my case, the nearest is a wolf3d dealer/tuner about 9hrs away. The nearest Haltec on the other hand is about 20 hrs from me. That was a HUGE factor in why I chose to get a wolf3d system, plus I found a great deal on one from a forum member.

 

Fastrotaries,
Keep in mind that this is my opinion based on my personal experience. To those who don't care to hear a bit of a rant, please scan down and bypass my post.

I had decided last year to go with the Wolf 3D v4.0. I got in touch with the Southeastern dealer, SPiN Racing, and talked about it a bit. Things looked pretty good until I actually tried to order from him. My money was sent in December, long before the system came stateside. A month after it got to the states, I was still without a system. I tried often to get in touch with SPiN, but usually didn't hear back. Once when I finally caught up with him, I was told that it HAD been sent, but that because the power was out at that moment, he couldn't give me a tracking number because it was on his computer. (Funny that he didn't have a paper copy of the shipping number like everyone else gets). Anyway, a week later, after I didn't get the tracking number, I threatened to take my money back and go elsewhere. Shortly thereafter I received an angry email from him saying that my money would be refunded due to the fact that "he never got the system, so he couldn't ship it to me". He also said that he couldn't understand why I would call him a liar and question statements he had said about the status of my Wolf. Well, he DID tell me that it had been shipped, but then he admits that he didn't even have it to ship?!?!? WTF?

During all of this, I didn't receive much help from Ron at Wolf USA. He listened politely enough, but nothing ever got done. My girlfreind managed to speak to the wife of the owner of SPiN (I wasn't in the politest of moods that night), and she was told that my Wolf had been sold to someone in the Florida RX-7 club. Hmmmm. . .could THAT be why I never got it?

So, my money was supposed to be sent back to me, but I kept hearing reasons why I hadn't received it yet. "My tax return hasn't come back yet" was my favorite. I finally sent copies of all our email conversations to Wolf Australia. They tried to be helpful, and the owner, Steve, called Ron personally to arrange a way for me to get a system. Well, Ron never called me like he was supposed to. That showed me that Wolf didn't seem to want my money. Oh yeah, I almost forgot. . .I am STILL waiting to get a CAS back in exchange for the one I sent them to be modified to work with the Wolf.

I FINALLY received my money (about 2 weeks after it was supposed to arrive) from SPiN. I called Australia once more to let them know what had happened. They offered to send me a unit direct from them, but I turned them down. I told them that as nice as that would have been, I would still be stuck with getting tuning tips from Wolf N.A., and they didn't show any interest in dealing with me when I COULD get in touch with them.

In the end, I decided to go with Haltech directly from the HITman in Australia. He is very active on the Haltech forum, he responded to my inquiry within a day, and he supplies his system with a map based on the mods you have in your car. Oh yeah, it's also $1300 SHIPPED from Australia. Can't beat that! With a discounted price, my Wolf would have cost only $10 less, but this way I'm getting some of the best support in the world for my EMS.

This is a slightly abridged version of what happened, and I apologize for the length. The main point of this post was to stress that it's not only cost that makes the difference, but service during and after the sale. Feel free to contact me if you need to hear anymore.

Does anyone know the non-preorder/discounted price of the Wolf 3D V.4?

Also. are they actually in stock now, or are we still playing the waiting game?

Thanks!

BTW, cool Forum ID NOTA944!

 

They are instock. I talked to WolfUSA a couple of days ago and they had one unit in and they said they would have more in three days.

 

What's the anti lag/boost control for? Would i need it if i have a G-reddy Profec B.

 

I am a Wolf dealer in Sac, CA. the system is very good!!
I have installed many ems systems on a lot of cars. I know what works and what doesn't. In truth, all systems work well if you know the stratagy of the system you are installing. The advantage of the wolf on rotaries is that it has a split L & T timing. Many of the other systems do not. The other advantage is altitude comp. The new 4.0 has had some delays and being a dealer I am truly sorry. I know that the owners of Wolf are great people to work with and if anyone has a problem please call me at 916-852-0306. I promise that I will be there for anyone installing a wolf system.

split trailing timing is only an issue if you need to pass emissions, if you have a race car or dont have emissions tests, firing both plugs gets more HP.

.................................................. ...............

it has been discussed and debated and it has been ended, firing them both as the same time provides more HP.

 

Heh heh. Thanks Jim!

 

Hey, no problem Reese.

I called Wolf. $1380 + shipping, and can be had overnight...

 

The haltech can do split timming...

The main thing to think about is if there is a competent tuner near you.. Both the New wolf & haltech e6K are very comparible..

The haltech does have a lot better rotary & online support. That is why i choose the haltech..

So firing both gievs more power....makes sense, it's more spark. Question here is: "Should you then make the trailing spark hole BIGGER since it's not the same size as the leading." if you follow the presumption that more spark has the ability to fire more gas ( on a molecular level ) Makes me go Hhhhmmmm1

 

have wondered about that myself but i think it would increase the chances of detonation as gas could escape into the combustion phase by bypassing the apex seals as it goes across the larger hole


the mazda race motors with 3 plugs per housing all fired at the same time
