While this looks feasible in some respects, I would caution that unless you know what the I/O interface properties are, you may be violating circuit constraints which would then risk a blown sensor or worse. I offer the following scenarios:
1. Each output of the GPS is an open drain that is asserted Low (or simply grounded) for a given gear selection. Then tying 3 output wires together into one input as you have shown is a wired OR gate and will logically work.
2. Each output of the GPS is an open drain that is asserted High (or simply opened) for a given gear selection. Then tying 3 output wires together into one input as you have shown is a wired AND gate and will NOT work as all 3 outputs must be asserted High simultaneously which will never happen.
3. Each output of the GPS is a CMOS type output that is asserted High (i.e. actively driven high) for a given gear selection. Then tying 3 output wires together into one input as you have shown is a definite circuit rules violation as the output that is attempted to be driven high will be actively countered by the other two outputs which are actively driven Low, thus causing a near direct short to the supply voltage and maybe a fried GPS.
Perhaps you've already found that it does work as shown, in which case scenario #1 is most likely true. If it doesn't work, then beware of scenario #3 which could end up costing you some $$$ to fix.
Good luck in your efforts, I wish I could do the same but the DCT control needs to know the actual gear selection otherwise it would be constantly trying to downshift below third and never finding it.
Did you see that youtube video of the kid that throws down his brand new gixxer as he guns it out of the dealership? Rear wheel just spins out like the tire was made out of plastic! Then down she goes...
I saw a video of the VFR1200 being driven by a journalist at a japanese track way back at the initial release and he spun out the rear wheel...saved it, but still... I have a feeling 'if you don't know what your doing' the torque at the rear wheel will bite you in 1st or 2nd gear in this new VFR1200, so Honda played it safe. That's all they needed, all kinds of stories about it being a 'dangerous' bike. I think that is why is has been restricted...poor man's traction control.

I have also heard that the new 2012 bikes with TC also keep this restriction!
Yes the 2013 is still restricted although I haven't measured it on a dyno yet. My 2013 felt like the real potential did not arrive in 1st or 2nd gear until well up into the RPM band. It felt like there was a hesitation in the 3 to 5 thousand RPM range. Installed the Z Bomb and everything changed in 1st gear. Suddenly the bike was trying to lift the front wheel in 1st which the traction control immediately kicked in and shut down the fun (TC light comes on and bring the front back down, feels like hitting the rev limiter). Turn the TC off with the ZBomb installed and the bike will now do nice but not dangerous power wheelys in 1st gear. This is with a compleatly stock bike except for the Z Bomb. I will have the bike on a dyno sometime in November after making all the changes I have planned. I want to quantify on a Dynojet how much difference the Z Bomb de-restriction makes on my 2013.
