I need to make a trip to the dealer to find out if there are different listings for the standard CVT2, the CVT2L and the AutoStick for these parts: Shifter, TRS, cable and anything else that I can think of. If someone knows of some other mechanical piece that may affect the linage I'll add it to may list.
Id like to know if the shifters have the same gate positions and throw too. if "L" is the same as "+/-" then I can use the stock shifter.. "L" would put it into +/- mode if I can trick the TCU into thinking theres a autostick shifter. then I can use any switches I want to shift.
what I was thinking of doing was this: use the wheel audio controls as paddle shifters and leave the stock shifter there. be able to go either paddles with no (or limited) wheel audio controls, or stock with normal shift and full audio controls.
Im sure I can do this with a PIC (PIC is a small computer about half the size of a deck or cards, programmable with lots of input output capability) I would insert the PIC in between the steering wheels CAN bus (think its CAN anyway) and the rest of the CAN bus so I can isolate it.
in BYPASS mode the pic would be invisible and just pass the data from the wheel to the rest of the system. everything would work stock. "L" would select "L" and wheel audio control work as normal.
in PADDLE mode the PIC would intercept any data from the left wheel control and send a DOWNSHIFT signal hardwired to the TCU, any right wheel audio control would send the UPSHIFT signal to the TCU. "L" would actually be the +/- position. I would lose some (or all, depends on how I program it) of the wheel audio controls while in PADDLE mode though.. small price
the PIC I was thinking of has 8 I/O ports.. 2 for the wheels CAN bus, 2 for the cars CAN bus, 1 for upshift signal, 1 for downshift signal, 1 for BYPASS/PADDLE and one for an UPSHIFT light (maybe, that upshift light would take a lot of programming)
only issue is switching back and forth.. I need to know exactly how to trigger a "see if I have autostick" easily.
and I would need to know how to ride the CAN bus so I can program the PIC. Im sure CAN protocols are floating around somewhere.
come to that, do the steering wheel audio control signals use the CAN bus?
