tach signal
hey guys.... im testing a somewhat proto-type 2 step unit for the zx14 and need a good tach signal . Im wondering where theyre picking it up for dyno testing ?
Im told the 14 doesnt have a standard tach signal to the tach

We just clipped the dyno pick-up over a plug lead, prior to the stick coil. Couldn't find a satisfactory signal up at the ecu.

The manual says the 14 uses a twisted pair to send binary signals to the ecu which decodes the signals and operates the guages. This system they call the CAN system. If cut into it will likely be destroyed.

i was afraid of that... im wondering if i can use a signal right off the crank signal . if i can get this to work out itll be a nice alternative to the msd .

also , anyone used the msd and know if it trips the FI light like it does on the busa ? thats one of the "features" we're trying to avoid .

Save yourself hassels and go to the ecu for the signal. Just discovered this past weekend in working with Ray from MSD that if you have an ignition kill tied to the neg side of the coils for an air shifter it interferes with the MSD light. For a 2 step I'd err on the safe side and pick up the signal back at the ecu, right (throttle) side plug white w.blue tracer wire.

i am trying to hook a dyna shift light into the tach on the bike. could somebody tell me whitch wire is the tach signal wire and witch one is the power wire. could you also tell me if it will hurt anything if i splice into these wires .
thanks.

Use the white wire with red tracer on the coil on the left side of the bike... Get your power from the red wire with the silver tracer coming from the kill switch on the right handle bar .... or go all the way back to the fuse box and tap into the turn sig wire ... or any wire that is hot with the key on and cold when it's off...

i hooked into the white wire with the red tracer, and hooked the other wires like you said . i still can not get the shift light to work. it gives the quick flash to acknowledge it is getting power, but when i get up to 8000 it will not flash. any ideas. i was just wondering if i am tied into the right wire on the coil. i did splice into the white wire with red tracer of the coil on the left side of the bike.

Have you gone well past 8,000? Just wondering if the tach is way off from what the actual RPM is..... Just a thought....

i went to 11000 , and still nothing. but i figured out the problem i need to tie into two coil wires to get the right signal. i was only picking up half. so i will see what that does.

Go back to the ECM to get the signal. If you are running a digital ignition kill it interferes with the signal needed for the shift light.

I'll be running the muzzy air shifter, so I'll be digging into the ecu for that signal.
thanks for the help.
BTW, Chip, the swingarm is just kick ass. thanks

Did you ever get your shift to work, once connected to 2 coils?
