FE570 Map Switch

Davo · Apr 16, 2010

I am making my own Map Switch as the Husaberg Map Switch is just too hard to change when you are at the bottom of a nasty hill and all your mates are shaking their heads while you are pulling your gloves off and trying to get to the switch.

What could Husaberg have been thinking when they gave the go ahead to use that Map Switch? They made such a great bike with such a crap Switch

Here is a bracket I cut out of Alloy and had my mate weld onto the Bark Buster Bracket. Tapped 2 x 4mm holes in it:

Here is what it will look like:

The Map Switch Cable uses the same connector as a LS1 Chevy V8 Knock Sensor. I just happen to have a LS1 in my garage (Bridge to Bridge boat race project for 2011). I don’t use Knock Sensors in my LS1’s so it’s a free donor cable/connector:

Picture of the Resistors all soldered in place on the Husaberg Blinker Switch:

Here is a Wiring Diagram.

If you follow this diagram it works out as:
Left Blinker position = Standard
Centre Off = Soft
Right Blinker position = Aggressive

Solder 1 wire to the middle pin on the Blinker Switch (labeled 1 on the Switch)
I used a 15K Ohm resistor between the 2 wires coming in. That gives 15K resistance when the Switch is in the Centre (off position).

I then used a 6.8K Ohm resistor between the Right Side Pin (labeled 3) and the second wire. When the left Blinker position is selected the 6.8K and 15K resistor are connected together giving a result of 4.68K Ohms.

I then used 2 resistors in series, a 12K and 500 Ohm resistor. This gives 12.5K Ohms. When the Right Blinker position is selected the 12.5K Ohms and 15K Ohms resistors are connected together giving a result of 6.8K Ohm. Solder one end to the left Pin (labeled 2) and the other end to the second wire.

This closely matches the values I measured from the original Map Switch:
1 Soft = 15.03K
2 Aggressive = 6.79K
3 Standard = 4.67K

After I finished I measured the Blinker Switch and got:
Left = Standard = 4.66K
Centre = Soft = 14.98K
Right = Aggressive = 6.77K

I am going to Araldite it all up and try it in the morning.
Do they call it a Blinker Switch in the US?

really cool, thanks for taking the time to post this up, I too do not like the stock stupid switch, hard to use for sure.

Looks nice! Can the different maps be accessed "on the fly?" or do you have to stop, shut down, and re-start the bike to switch?

Thanks, Blumpkin

Just like the switch that KTM/Husaberg supplies, you would have to stop the engine and restart it.

Is the change between "Aggressive" and "Soft" mode subtle or very noticeable?
I couldn't really say I noticed much difference. I only tried it on a tar road. Maybe I need to try it on a hill or in the sand. I never noticed the difference with the old Switch either but put that down to not switching it to the correct position. I did stop the bike each time I changed it.

I was a bit nervous in “Aggressive” mode, I lent over the front as I took off, waiting for the bike to try and spit me off

Generally I now always run on 'soft' because I ride technical trails a lot and the bike still has plenty of power in any mode. I can still pop third gear wheelies if I get carried away with the throttle.

I have noticed very little difference between the modes just putting around. Mostly the difference is in medium to wide open throttle at the middle to upper RPM ranges. In none of the modes is the power delivery sudden or abrupt at any point.

Davo · Apr 17, 2010

Thanks Codemonkey. I was thinking it was going to be noticeable in the low RPM to Mid RPM. As usual I'm wrong again with assuming Husaberg EFI behavior.
Anyway it’s heaps easier to change Maps with a Blinker Switch. The Switch is sturdy too so I think it wont accidently get switched when falling off or bumped.

Here is the last photo of the Araldite and the Blinker back plate. All the resistors fit nice:

I did a similar thing with the blinker switch. Only differance is I did not use anything for the standard position, as it was just an open circut as is when no switch is attached. Left blinker= soft, right blinker= aggressive. middle is stock. Works a treat

Davo · Apr 18, 2010

Hi 69candy, I thought of leaving out the 15K Resistor, but wondered why Husaberg put it in the stock Map Switch so I just made it the same. Maybe I overcomplicated the process.

So can you tell much difference between the Maps?

CrazyTed · Apr 19, 2010

I don't notice anything when I'm just riding. I was working on our last course and felt like my back tire was dancing around too much. I switched to the soft mode and that feeling went away. Bike still has tons of power so I don't call it a "soft" mode. I call it traction mode.

sabink · Apr 19, 2010

The difference is easily noticed on the throttle twist. When in aggressive mode bike needs less throttle to accelerate, e.g. it feels much more sensitive.

When I first started playing around with my map switch I asked this same question until I put my bike on our speedway track, then the differance was very clear. With the map set to soft (where it was when I first went on the speedway track) I found it very hard to get the rear wheel to spin as I needed to slide the rear end out. The instant I changed to the aggressive map it would spin out very nicly with just a small touch to the throttle.

I feel the same as others here, that most of the time the power this bike delivers it does not really matter where the map switch is set.

My thoughts are:
Aggressive - Fast open track, speedway, popping easy wheelies ETC...
Soft - Max traction for muddy snarly rocky uphills

You made the same as maps 1-2-3, but you could just stick to 1-0-2 for the same results and way easier and cleaner soldering... 8)

Has anyone noticed an increase or decrease in fuel mileage with the different maps?

Hi MexMex, I updated the wiring diagram on the way I should have done it with 2 resistors

If I would have known 2 weeks ago that 70 Degree Racing was going to release a Map switch I would have waited and just purchased one.
As Homer says, "DOH!"

69candy · Apr 24, 2010

Stock and aggressive maps rev out a lot further and quicker. The aggressive setting is also a lot better on fuel IMO than the soft and standard setting

I also intend to replace the crap OE map switch with something along these lines but the resistance values I get are slightly different to the above.1 & 3 are the same but 2 (Aggressive) is open circuit! The dealer told me the default map with no switch fitted is the full power or Aggressive map so this ties in with the reading I got. I'll probably leave the indicator switch mounted in the original position on the LHS of the bar.

I am confused.

I just measured my Husaberg rotary switch and got the following readings:

0 = open
1 = 14.9k
2 = 6.8k
3 = 4.68k
4 = 3.3k
5 = 2.7k
6 = 2.2k
7 = 1.9k
8 = 0
9 = 0

The instructions say that 1 is soft (15k), 2 is aggressive (6.8k), and all of the rest are standard (open OR <4.7k). I can understand 3 through 9 being the same since they are all 4.7k ohms or less. But zero is open. Is open and less than 4.7K really both the same setting - standard?

Is leaving the switch disconnected (open) really "standard" or is it "aggressive" as pegscraper suggested?

I like the idea of a two resistor switch, but what values do I use? 15k and 6.8k as the instructions suggest? Or 6.8k and 4.7k as Davo's updated drawing shows? If the instruction sheet is correct, Davo's drawing will give you aggressive, standard, and standard - you can't get to soft.

Can someone please clarify? I suspect 15k and 6.8k and open are the correct choices to get all 3 map settings, but I would like some verification before I build it up.

Thanks,

Dee

*****, I made a mistake. :crazy: Sorry Sorry Sorry. Will try and update my diagram.
You are correct the 2 resistors should be 15K and 6.8K (The 4.7K is wrong)

If I was to do it again I would just use a 2 way Switch with aggressive and soft. I never use standard.
