microtech/wolf for economy

Madrangie, some pics would be good, what kind of setup do you have and how much did you spend ? Also I am wondering what the best way would be to install a MAP sensor ? And do u use a LR one.... so many questions.... 8O

It would be interesting to give this kit a go !!!

This unit is a huge revolution in DIY automotive performance. It gives you the power to completely tune the air/fuel ratio throughout the entire load range, at 128 load points, providing incredible mapping resolution and brilliant drivability. It uses the Handheld Digital Controller – KC5386, so there is no need for a laptop, and it supports both static and real-time mapping. It can be used on 0-5V and 0-12V signals, so it is compatible with all voltage output airflow meters and MAP sensors. It can also be set to work with 0-1V signals, allowing modification of EGO sensor signals. This unit has been extensively tested on a wide range of cars including Subaru Impreza WRX and STi, Nissan 200SX, BMW 735i, Lexus LS400, and Nissan Maxima. Kit supplied with PCB, machined case, and all electronic components. Kit requires the Handheld Digital Controller – KC5386.[/b][/quote]

My wolf cuts the fuel supply (petrol only) at over 1200 RPM when locked up in 1st low and foot off accelerator so provides extra braking downhill. It's quite effective.

ShaunP, I think, has also mentioned in the past EMS of Sydney.

I contacted them this week:

Hi

Our units suit most engines. You simply define the type of ignition system in the ECU setup screen. IE: Number of trigger teeth, Number of igniters etc and the ECU does the rest. Some engines require special functions.We also cater for this by providing a number of selectable ignition modes.

We have two units avalable, the 8860 and Stinger3.

The 8860 costs $1595.00 and the Stinger is $995.00 AUD.

I've used an EMS dual sport (the model before the 8860) on supercharged 393 chev and it works very well, engine make almost 700hp at the wheels. We used this unit rather than a wolf at the time becuase the Wolf could not switch enough current to open the injectors we needed to fuel the engine as they are very low impedance. We trigger it off a magnetic crank trigger and run a Crane CDI ignition.

G'day ShaunP,

Thought it was you that had used EMS equipment.

So would you recommend using it on Rover V8's?

If I'm using a 3.9 EFI with hotwire as a starting point what is actually involved ans what sort of money do you think it would cost all up?

THX in advance.

It will work fine. The unit comes with a wireing harness so you just have to rewire the engine. I had a few problems but they were related to this Chev as it's a pretty tough engine. The ECU needs a good tacho sense, I had trouble as we were using a high energy CDI ign, you can use a Crane tacho drive to fix this, if you what to run a high energy ign system, I ended up using a magnetic crank trigger fitted to the harmonic balancer. We also had trouble tuning this engine using the MAP sensor, this was primarily due to the amount of air the engine moves when the blower comes on boost. As a result I could give it enough fuel at this point due to the response time of the Map sensor, I got the firmware changed so I could just tune on throttle postion only, problem fixed. This won't be a problem on your engine. There is a couple of traps in the software of the Dual Sport but not sure about the later ones. For example when you a building the fuel ign map the numbers you put in the spead sheet don't really relate to anything. I got confused thinking that if I put in say 10 in the ign map I would get 10 deg of advance but you don't, once you work these things out your fine and the new ones may be different. You can down load the software from the web site if you want to look. It took about 2 hours on the dyno to tune this engine. I reckon if they will run a supercharged 393 with dual throttle bodies and 700hp it will run a 3.9 no trouble. Just make sure you get all the option in the ecu that you want first up.
