GSXR Hall Effect Tilt Switch removal
G'Day all from the sunny South West....
I'm currently making another loom for a post-K3 vintage GSXR, so again I find myself squirting silicone into the tilt switch. Has anyone managed
to (simply) bypass this thing altogether. It's not the simple K1-2 mechanical switch that you simply throw a 68K resistor at, it's the
later 3-wire job, where in addition to the 5V reference line, there's a 12V to power up the Hall sensors that the magnetic rotor interacts
with.
Simply replacing the 4K-15K-19K resistance requirement, doesn't work, the logic requires a time delay segment between the (several) sensor
chips.
Suzuki have me puzzled on this.

this is how we bypassed a 2004 gsxr1000 3 wire switch, HTH
Tip over sensor
connect red -> 15k resistor -> black
connect black -> 3k resistor -> black/brown
2 resistors across 3 wires.

Yep, that's exactly what I did. It turned out not to be best way to do it (rather like permanently shorting out the clutch switch). The ECU went
into a 500 rpm dropped downtune map. Putting the titlt sensor back (as with reactivating the clutch switch) instantly gave the 500 rpm back. I get no
error codes if the brain isn't totally happy, just a downtune.
I'm still looking at the time signal thing, also trying (as are many) to get through to the ECU with ROM raider.... it's only a matter of
time (hopefully).
