I just finished my first track day on the 1299S. All day I had problems with the DQS not working. DTC as well as DWC were also showing a fault light on the dash. Up until this point the bike was working fine with no issues; however, I had made several changes which I hadn't had a chance to test before the track day. I'm trying to sort out what is happening, so that I can resolve it quickly. Ill list the changes so that maybe some of you will have had this issue and found a solution. Bike is essentially stock with the exception of a Rapidbike module.

Track prep:

1. I removed all the OEM body, headlights, taillights, turn signals, front fairing stay etc. I DID NOT PLUG ANY OF THE OEM CONNECTORS. I do show a brake light error code on the dash.

2. I added Bonamicci rearsets and use a translogic shifter which previously worked great.

3. I replaced the front fairing stay with a motoholders unit which does mount the IMU, I did not power up the bike until the IMU was mounted.

Other than that the bike isn't changed. I left the OEM fender because of the wheel speed sensor mounting and I do run warmers, but I don't know if the sensor could be damaged. any ideas?
 
I would really check all the connections make sure everything is plugged in the right spots. Also check to make sure the gap between the front/rear sensors have the correct gap to rule this stuff out.
 
I'd suggest getting the plug kit.

This way your warning lights are off. I'd guess all the systems are tied together so if you're getting a brake warning the other systems will be affected. DWC and DTC all go together with ABS and all use the wheel speed sensors to work. So maybe since the fault is showing, it throws everything else off.

A friends bike was just stripped and made into his racebike for this year. He used all the plugs from the kit, no warning lights and everything works properly.

I'd start there.

PS; be sure to get both front and rear kits. Jarel lists them both in his posts in that thread.
 
I've already ordered them since that is the most likely culprit. Gonna check fuses and test my shift sensor. It worked fine before so I suspect the plugs.
 
I'll be having to order the plugs shortly myself.

Could the IMU angle be off with the motoholders fairing stay? I know that if it's off by just a little bit from its stock location, everything starts to go haywire

I'm not certain. The error being generated is the one shown in the upper right corner of the dash (triangle with circular error) which corresponds with a black box error. There is only one error displayed on the screen which is the generic stop signal error.

I replaced the fairing stay while converting mine to a track bike, keyed on before remounting the IMU and got all sorts or errors. I islolated the battery to reboot everything and all the errors cleared . I used an LED strip wired in to the tail light and brake light to stop one error and installed the side stand eliminator kit for another error code.

Luckily I saw the IMU warning in the book and was sure to not turn the key. Doesn't mean it isn't in fault though.
 
I have installed a Motoholder fairing stay also and my dashboards shows IMU error. I thought DTC was working (because IMU is supposed to help DWC and ABS) until I performed a nice, big and painful highside on friday.

I wonder if anyone else uses the Motoholders fairing stay? The IMU holder is rock solid there. It might be too rigid to avoid vibrations.:confused:

From what I've seen it's best to keep the rubber dampening mounts.

Thats all I have for the time being :)
Im OK. Some seriuous headaches and some back pain but nothing is broken. :)
I'll try to get a video but not sure I want to watch.
Looks more scary than it really was :)
 
@Szab25 - I too am glad it wasn't worse for you! But hey, it couldn't have been that bad if you were able to take a selfie while on the gurney in the neck brace and wired for fluids! lOl
 
Just an update. I installed the plug kit which cleared my brake light error but didn't change the DQS issue. I did however figure out the problem with the QS. It turns out that the shift linkage is pretty finicky with regards to its geometry. If you don't have it aligned just right there is enough binding to keep the sensor from triggering. This is true for both the OEM switch as well as aftermarket switches like the Translogic. The bike will still shift but the sensor will not work.
I don't have any dash errors now but will follow up once I verify DTC works as well.

Good to hear. It's important to keep the shift levers and rods as close to a 90 degree angle to each other for the best quality shifting even without a QS.

I generally try and keep the arms of the rear set and the shift shaft parallel, but I had installed my rear sets hastily and didn't get a chance to ride it before my last track day. When I came home and looked at it is was a ways off. I fixed it so they were parallel and then tried it and the QS still didn't work. I then swapped the TL QS for the stock and it was the same although the binding was more noticeable with the stock QS sensor. I changed the angle of the shift arm (one spline CCW from the marked stock position) and it made all the difference.
