Super Tenere XT1200Z "Hooligan switch" - HELP NEEDED

[Waspworks]

Hi folks.
I have many times on the trails (mud, boggy sand) and at traffic lights (hooliganizing + wheelies, etc) wanted a "quick" method of switching the TCS and ABS off.

Now before all the koolade swilling, mocha latte sipping BMjubbly riders start beating their whale foreskin clad chests, read on and hear me out.
I have had 10 pleasurable months and done 12,000 kms on my S10 to know what I want.
Both the TCS and ABS systems work great on this bike but there are times that for my own reasons I would prefer to be able to turn them off - Quickly and temporarily.

The latest time (and typical example) was earlier on this week when I took a between building sites detour only to find bottomless quicksand with some large rocks (still passable at a slowed pace) blocking the path.
The problem with the TCS switch on the dash is that you need to stop and hold it in to be able to switch the TCS of... The ensuing loss of momentum obviously leads to instant bogging and a pain in the arse.

I am not interested in making a kit for the S10 as its probably already been or being done by people that have less fear of litigation or better liability insurance than I can afford. This is something I want for my bike only.

But, I need a hand. I am hopeful there is someone out there who is better with electrical schematics or working knowledge of this type of wiring that can advise the best possible method to achieve my desired outcome.
I dont care if this switching results in the dash lighting up temporarily, and I dont need individual control to switch of ABS or TCS, in fact I prefer to switch them both of at once and then, if necessary, stop the bike and start again with the system normal after switching back. I do however want to be able to deactivate both systems instantly and on the run.

I want to be able to flick one switch on the L/H bar to disengage the ABS while at the same time render the TCS inoperable.
I am not sure what the aftermarket suppliers are offering at the moment and dont really care. I assume that if the supply through the ABS fuse is interupted, the ECU will see a fault and disable the ABS. A part of this assumption is that the TCS will also fault because it must register that there is no signal from the ABS.??? OR, does the signal from the front and rear wheel rotation encoders seperate and run parallel to both the TCS controller/ECU? and the ABS ECU??

I have done a couple of tests and pulled the ABS motor fuse (#6 in the pic) and that disabled the ABS but did not fault the TCS (ran the bike for a minute on the stand - up and down gears).
I also pulled the plug for the rear wheel sensor (in the harness under the tank) and that had the same effect.. Did not fault the TCS.
Just to check, i also ran the bike on the stand in second gear (20>30 seconds) and both the ABS and TCS faulted.

This has me confused. Is it just a matter of interrupting one wheel sensor wire (feed in or feed out)???
I read in a very early test that the ABS and TCS was deactivated if the sensor was unbolted from the front wheel and zip tied to the side of the fork leg. This indicates that the system still sends a signal to the sensor but does not get the required info back therefore faulting the system.

I am sorry for the picture size but I thought it would be best this big to be able to properly see the details and even print out.

Come on guys. I know there are some smarty's amongst you...

Greg.

P.S - Note: the front and rear wheel sensor wires are shielded so I have no idea if they can be cut into to be able to tap a wire up to the bars.

In your example, I can see how it could be handy to instantly deactivate the TCS in a siituation. I believe the manual even recommends turning TCS off if stuck in such stuff and I can see how turning it off quickly could help. However, I don't see the reason to want to also turn off ABS at that time. I know I am probably overlooking something and am interested in your reasoning.

BTW, it would be easy to install a switch to turn off the ABS instantly, but I haven't considered a switch to instantly turn off the TCS.

Thanks

I was trying to see what the Service Manual says about TCS. It seems there many inputs and Outputs that manage the TCS. i.e. wheel sensors, ignition timing and a whole slew of other engine management sensors. If you can tap off of the TCS Switch and mount it on the handle bar, that might be your best bet. I couldn't find the TCS switch in the Electrical schematics though.

Why dont you try a momentary switch on the center stand switch.... Hold it down and it should think that the wheel is off the ground.. Red light should come on and good to go... To reset it Yamaha many times use multifunction relays that are triggered off the ignition. They can all be manipulated and changed... A thought is..... you might be able to have an on/off power switch in -a- line and have an easy way to trick power on / off to that to reset it... If any of that works you can get a multi function button to pretty much do what you want........
If I had the dang bike I could go out in the shop and try it first then post...... that might be awhile...... O

Mission accomplished. With a bit of help from a couple of guys.. Thanks fella's - You know who you are. 8)

I tried quite a number of different scenario's and, in the end, the most viable was to tap into the wire leading into the 7.5amp ABS ECU fuse.
The switch is instant on the move and immediately disconnects the ABS and TCS without needing to stop or slow down.
Switching back the other way on the move immediately reconnects the ABS but leaves the TCS inactive... The ignition must be turned off and the engine re-started to reinstate TCS.
If the engine is turned off with the ABS/TCS systems deactivated, these features remain deactivated when the bike is started again.

The great thing about how this works is that there is always a light/s on the dash to warn/remind that these safety systems are deactivated.

Very pleased with the result, and had a blast during the test runs.

Wasp, good to see you got this figured out - and the results can be seen in your latest videos.

What I want though is something slightly different. I'm generally in the "I don't care if I can't switch off the ABS" camp as far as the S10 is concerned. I'm sure the Yam ABS is great off-road and on, 98% of the time, and I would bet even off-road the ABS would save your skin more often than not. However I was reminded recently how critical it can be to have the ability to lock the rear brake. I was bombing down a track on the Vee, had a nice rhythm and was having fun. Suddenly there's a deep washout going most of the width of the track, and I needed to be 3 feet <--THAT WAY, and NOW, to avoid it. Not too hard, locked the rear, got it pointed in the right direction and avoided disaster.

I can't think of a circumstance where I'd ever want to deliberately lock the front, so I'd like to keep ABS active there. I just want to choose ABS or not on the REAR only.

This has the added advantage that if you forget to switch ABS back on after transitioning from dirt to road, it's not a big deal - it's still active on the front where you get most of your braking on tar.

So Wasp my question is - can you or any of your genius mates figure out a switch for REAR ABS ONLY?

Yes, I like your way of thinking... That would indeed be the ultimate.
However, I dont know if this is possible considering the intimate relationship with the front by virtue of unified braking (but what would I know?)
It will take a smarter man than I to work that one out.

If someone was to take this project on board, here is my wish list: >
I would like a slimline billet left hand handlebar mounted switch housing (IP67 rated + black preferable )
This switch block would house two independent 2way latching rocker switches with inbuilt indicator LED's.
The top switch (rock's horizontally L/R) would be for ABS ON/OFF. LED to glow red when ABS is turned off.
The bottom switch ((rock's horizontally L/R) would be for TCS ON/OFF. LED to glow red when TCS is turned off.
The system should retain the last set position on both switches.

End of build request....

Regarding turning-off the ABS function for only the rear wheel:
In looking at this schematic, other motorcycle ABS schematics and understanding the logic of how the ABS works, it would take an ABS Control unit/ECU software change to make this happen. With this small of a production I doubt anyone will spend the time to crack the code to rewrite the Yamaha Control Unit Software. No one would pay the high price that would be required for this low demand/low production function.

Just use the above disable function and lose the rear and front ABS but, if you could figure out the adjustments and angles just right, you could set-up a quick attach zip-tie block on the front brake lever somehow that would keep you from pulling the front brake lever very far and it would be an "analog" front ABS for loose trail work. You would lose FULL front braking, but how often do you use hard full front braking on those kind of trails?

Personally, I am very hard on the front brakes all the time - Dirt or road... The ABS is only switched off to set the back up for fun corner exits.

I will probably do that if I can't just switch the rear, but it would be really advantageous to keep the front ABS in the dirt... I rarely lock the front in the dirt, but that's only cos I'm a woose and don't brake too near the limit. I suspect I'm missing out on a lot of braking potential, which would be recovered if only I could keep the ABS on the front. At the same time I don't care if the rear gets loose, and would like the option to lock it to help it get that way!

Hi Greg,

Which wire did you cut into and where. A photo would be good.

Also, does it screw with the speedo? I did some fuse pulling last year and the speedo stopped working.

Sounds to me like he is referring to Ray's unanswered question.

oh very clever.... .maybe don't drink and type.... or take your meds..

yes I was refereing to Ray's request for pics...

I wouldn't expect much. The guy who figured this out (Wasp) has long since sold his Tenere and disappeared. Disabling the ABS isn't real popular around these parts.

Since I'm such a cool guy, I did find this video on Youtube showing how to wire in a switch:

Disabling the ABS isn't real popular around these parts.

I am a big fan of disabling the ABS. I think ABS is a real hindrance off road, as is the Traction Control, especially using modern off road techniques. I turn off the traction control just before I hit dirt, as well as the ABS, for which I have one of those switches.

 

[cstatman]

ARGH! okay, i found what I want. how to turn off TCS/ABS and be able to hoist wheelies, engage in hooliganism

however? I do not understand what "tap into wire at 7.5a@abs ecu fuse" means.

I know which wire that is, but what is he tapping into? is he bypassing the fuse? what is this? what does it mean???

Any help appreiciated...

 

[Gun]

Yeah, Id like to know also. I already have an ABS off switch, but f I could rewire it to switch TCS off as well, whilst on the move, that'd make my S10 perfect.
