one of the guys over here in Sydney, Peter Higgs, was going to put a wolf on his 931 - haven't seen him for ages so don't know if he has done the job yet.

I've posted lots of links for EFI stuff in the links forum.

If you want to keep the standard intake stuff (charge tube, plenum and runners) then you "just" need to look at injector mounting (mod the standard mount holes or mount in the runners), a custom fuel rail, perhaps a new fuel regulator and some sort of crank angle sensor the computer can interface to (get recommendations from AEM).

Injectors will depend on any performance mods you are going to do at the same time. Have a look at the list here http://www.autospeed.com/A_0102/page1.html to get an idea of where to get used injectors from. Something around 50hp would probably be a good start.

On the spark side you can, but don't have to, throw away the distributor and go for a quad coil pack and ignitors. Find out what the wolf likes best and head down to the wreckers. Vaguely remember that wolf had problems burning out nissan coils - don't quote me, check with AEM and get their recommendations.

Peter that autospeed is a good page,will machine head to take bosch injectors,i have a 81/82 bellhousing/flywheel and would like to use that factory sensor as 1 input.May have to chnge pick up points for the wolf,i think the new version of the wolf is good value for money whats your opinion,mike

the price ($1100 without hand controller) is excellent. The only thing that seems a bit off is the extra charge for the tuning software.

Have you read the review in the current (#55) Zoom mag?

Peter,picked up zoom 55 yesterday,and i am now sold on the wolf 3D,i have a windows 95 laptop so may splurge on the software,is your 931 stock,mike

The software is where they always kill ya. The tactic used by the 944 turbo boys is to get one guy to buy the software and the other chip in to copy and tune it.

Mike, my current ride is a '79 NA 924. If this depression in the IT industry ever ends I'll be looking for a 931. In the mean time I'm going to rebuild a spare 924 engine and use a haltech E6K with the EFI Hardware throttle bodies.

Rick, this is the first time I've heard of an Aussie EMS where the tuning software was not included in the price. I know the Japs do it to force you to use their "official" tuners. I suppose it reduces the number of support calls and lets them advertise a lower price but I think it sucks.

Rick MacLaren · Guest

Yeah it does suck. The first I heard of it was through Electromotive. What galls me about it is that to really create a flat line representing the relationship between, say, richness/lean and RPM, or to DO whatever you want to do, you have to have the software or just accept their stock settings.

One guy on the Rennlist 944 Turbo board went out and invested the money in some fancy software and the electronics for it. Then he set up his laptop, hooked it up to the car, and generated settings taking into consideration mass air pressure, using their sensors, fuel delivery, boost, and so on. He measured EGT, intake charge, knock, all that jazz. Then he tuned up the software to give just the right spark at just the right time. He optimised it using the software.

Once done, he then, and I have no idea what process he went through, altered the chip to fix these optimal settings. Now he's selling the 'kit' for just that particular car. So the person buys the hardware, and it's all set up and ready to go. All they need is the box, sensors, air intake and a few other goodies and they're ready to go. No worries about detonation, exhaust gas temperature, cylinder head temperature, or anything that'll blow up your car. Pretty smart cookie if you ask me. Some bugger could make a fortune if they did that here to one of our cars.

actually the software is only A$100,i have a old win95 laptop so i am laughing,just gotta get the sensors and injector plugs,cant be too hard.

looks like the wolf comes without sensors, is that right?

When you compare it to the haltech E6K that comes with software, coolant sensor, throttle sensor and air temp sensor the price difference is not that great. The haltech still needs a MAP or MAF sensor and a crank angle sensor for anything other than a NA race engine. Also the haltech uses a 32 bit compared to a 16 bit one in the wolf.

Still, as they always say, the most important part of an EMS are the factory support and the guy who tunes it.

Peter you are right re sensors,i am going to add everything i need and compare prices,the fueling looks much simpler to change with the haltech,i have a dry sumped 2.0 MK1 Escort that i wish to swap the aftermarket ecu onto occasionally.

if you're going to swap the ecu between 2 cars the wolf might be better. It has the swappable memory cartridges (don't know how much a cartridge is) so you can set it up for your 924 on one cartridge and for the Escort on another cartridge.

Send Haltech an email explaining that you want to use the computer in two cars and see what they say.
