Tuneboy QS and Blipper Strain Gauge Not Shifting.

Hi all, I have a Tuneboy tune and qs/blipper on my track bike, and the issue I’m having is that when I try to shift up or down, I can’t. Sometimes if I really mash on the shift lever I can get something to happen, but essentially I have no qs/blipper.

The screenshot below is of my settings, which I mirrored off a friend whose setup works perfectly. I also copied his tune, so everything is the same. However, it’s like my bike isn’t recognizing there is a qs/blipper. Or that the blip and kill pressure are set to hard even though you can see they are not.

When I start the bike, the strain gauge flashes once, so that tells me it at least gets some sort of signal. I’ve read the instructions front to back. Wondering if someone has had a similar problem and resolved it.

How have you wired up the QS? Which O2 plug and have you tried swapping them?

I don't have the QS, but it sounds like it's not getting the input to the ECU. Have you checked to see if there is a signal going to the ECU?
 
It’s currently plugged into the O2 Plug behind the ECU. Where is the second one located?

Regarding signal to the ecu, how would I check that?

Thanks for the help again, Disco!
 
I'll find a pic. I tried to explain, but it's harder than I thought.....

It's under the black plastic circled. You can test the signal with a multimeter
 
Reading the manual, did you configure the QS plug? You need to press down on the lever when it asks, then it knows which plug you're using
 
Yeah, I did and it said it recognized the shifter. Additionally, the fact that the Cordona strain gauge (Tuneboy rebranded) flashes red when I turn the ignition to on, tells me it’s getting signal.

I haven’t used a multimeter before, so maybe I’m missing something without that experience.
 
Tried unchecking the "swap shifter/nudge input". Pretty sure this is only checked if you use aftermarket buttons and it also goes into an O2 plug, but I can't find where I read that.....

Yeah, tried that and the next time I plug into the bike, it’s checked again. Basically won’t let me uncheck it.
