70 Degree Racing Map Switch Update

DaleEO · Jan 14, 2011

All,

For everyone who has bought a 70 Degree Racing Map switch I have a bit of some what embarrassing news. There was a bit of a mix up when we originally went into production on the map switch our manufacturer produced the switches correctly. However, we got some miss information that the switches had the incorrect positions on them so we had a sticker made to go over them.

Recently we discovered that the original positions on the switch are correct.

So, for anyone who currently has one of our switches with the sticker on it, simply remove it, and refer to the sentence below and the updated picture.

We apologize for the misinformation and any inconvenience this may have caused any of our customers.

The small dot on the bottom indicates the stock or OEM map, the L in the middle indicates the soft or traction map, and the H indicates the aggressive map.

Dale, I just did a resistance check on my 70 Degree switch and it doesn't compare to the Husaberg switch

H = 8 ohm Husaberg "advanced" position 2 = 6.8k ohm
L = 15 ohm Husaberg "beginning" position 1 = 15k ohm
. = open Husaberg "normal" position 3 = 4.7k ohm

Big difference. Can you explain?
The only position in the Husaberg switch that is open is position 0

Thanks, Ron

Here are the measurements I got from the Husaberg rotary switch:

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

According to the instructions position 1 is soft (14.9K), 2 is aggressive (6.8K), and any other setting is standard. So you can get standard via position 0 (open) or 3 (4.68K).

I don't know about the 70 Degree switch, but if they are really 8 and 15 ohms, that would probably be a problem. Perhaps 8K and 15K would be okay??? I don't know what tolerance the ECU needs.

Thanks for the posts gentlemen,

I'll check into it.

Hey Dale, I just verified my readings with a second Fluke DVM, plus here are all the ohm reading from my Husaberg switch...

H= 8
L= 14.9
.= open

0 = open
1= 15k
2= 6.8k
3= 4.7k
4= 3.3k
5= 2.7k
6= 2.2k
7= 1.9k
8= .4
9= .2

Need more volunteers to measure their 70 Degree switch

Does the 70 Degree switch really work? From those resistance values it looks to me that all three positions would give you "standard".

Here are two schematics that would give you equivalent functionality to the Husaberg stock switch in positions 0, 1, and 2.

I asked the guy making the switches the same questions about the values when we first made them and he assured me that they were correct. I just sent him another email to get a better explanation to post on here. He is very well known in the industry and makes many electronic pieces for all brands. I will post his responce asap.

I'm just glad to see Dale back on the site!

deeG dont take this to heart but the old build your own switch was covered when the new bikes first came out and is on here for anyone to find if they search for it.

the fact though that your almost trying to encourage people not to buy the 70degree switch on a what is basically a customer service thread for said switch i some feel is a bit wrong.

just my 2 cents worth.

Busa10 · Jan 18, 2011

Okay to do your own switch, but the 70 Degree is a nice piece and incorporates a kill switch that's necessary to change maps... although you can utilize your existing kill switch.

I am not trying to discourage anyone from buying the 70 Degree switch. I think it is a very nice product - I considered buying one. My concern was the resistance values that have been posted for the switch make me wonder if it works correctly. If it is wrong, I assume 70 Degree would address the issue. If it is correct, then we will have new information about valid resistance values.

I got my idea of building my own switch from the earlier post - but it also had incorrect information in it. The original schematic worked, but was overly complex. An updated schematic was then posted, but it had the wrong resistor values listed. I published my schematic, which I "think" is correct, in that thread as well. I am just trying to share information. Sorry if I hijacked the thread.

What's interesting also is that the Husaberg install instructions say their switch positions 3,4,5,6,7,8,9,0 = standard yet really only position 0 is open as in not having a switch connected as in how the bike is delivered stock.

So according to my measurements anything between .2 ohm (basically shorted - pos 9) and open (infinite resistance - pos 0) = standard map. Strange. In other words 6.8k ohms is reserved for selecting the hot map and 15k ohms is reserved for the mild map and anything else selects the standard map.

One thing for sure is if you're running the Husaberg switch and you want the standard map you need to select the 0 position. That's the only one that's open and as if no switch is installed. So..

Husaberg switch pos
0= standard
1= mild
2= hot

70 Degree we'll see what Dale comes up with

I just checked my 70 degree switch and the resistor values are 15 Ohms and 8.2 Ohms respectively, measured with a Fluke 77 and color bands confirmed. Looks like they are off by a factor of 1000. Wow.

Unfortunately, my switch was damaged in a race a while back, so it was no longer usable, so that's why I went ahead and took it apart. I checked the output from the connector and got those same readings, but thought something must not be right, so I cut apart the wiring and found the resistors and confirmed the color bands.

Are you guys sure these reading should be kOhms, not just plain Ohms? Because mine were Ohms. I guess when I actually had this on my bike it was just my imagination? Turns out I mostly rode with the "stock" map, though, thinking I was on the "traction" map.

I think I'll be making my own switch from here on out.

I measured Kilo Ohms on my original stock Husaberg Map Switch with my Fluke 75:
Soft = 15.03K
Aggressive = 6.79K
Standard = 4.67K

I would buy the 70Degree Racing one if I was doing it again.

Good to see Dale, John, Cypher, Weed and you back Barshoe. Where is Bushie and Petem?

My Husaberg switch was definitely kOhms. But the real question is what does the ECU need in order to select the 3 different mappings? Maybe the Husaberg switch is wrong? I haven't been able to test mine yet (too much snow).

Do you really think the stock Husaberg map switch has the incorrect values and the ones I had in the 70 degree switch were correct? The fact that I got 15 Ohms and 8.2 Ohms instead of 15k and 8k respectively is more likely a case of someone grabbing the wrong resistors out of the parts drawer without testing the finished product. I thought the 70 degree switch was supposed to have the same values as the stock switch anyway? But even aside from mine getting broken (my fault), it's looking like mine was a lemon from the beginning and likely never did anything.

nobrakes · Jan 18, 2011

Busa, looks like yours is the same as mine, unless you forgot to put a 'k' at the end of your H/L/o readings. 8.2 Ohms, 15 Ohms, and open circuit respectively here.

Also, I've confirmed the same readings as you for the stock map switch positions.

Yep, yours and mine are the same... no K missing. The wrong resistors were used.

Busa10 · Jan 18, 2011

to be clear... the 8 ohm and 15 ohm values fall into the range of resistance that selects the standard map so by that logic all positions of the 70 degree switch select the standard map.

Any updates, 70 Degree? I want to order one, but I'm going to wait until this is all sorted out.
