Strain gauge gear knob.
The Flatshifter “shift” is a strain gauged shear beam force sensor gear knob which has been designed to replace the OEM gear knob on a sequential gearbox to enable clutchless up and downshifting using our or any other makers gear shifting system or ECU ignition-cut
and throttle blip functions.
Compatible with Hondata, Nismotronic, Haltech, Cobb, Neptune etc etc
This gear knob utilises a full bridge strain gauged shear beam load cell that
causes the force applied to the gear knob cover to act at the instantaneous
a centre of rotation of the gear lever making the device insensitive to hand
position, unlike similar inferior sensors that use bending beam load cells.
The device is supplied complete with cover, cable and connector.
An amplifier module is supplied to excite the bridge and amplify the bridge
output. Several amplifier options are available to suit individual applications.

Flatshifter Amplifier Module options
1 Flatshifter Amplifier Module. This version connects the gear knob to the Flatshifter shifter system as an alternative to the shift rod ( gear shift sensor). The trigger level is set via the adjusting knob on the amplifier module.
2 Ref. 2.5 volts Amplifier Module. This version gives a 2.5-volt output with no load on the load cell with the voltage rising above or falling below 2.5 volts depending on if the gear knob is pushed or pulled.
3 Ref 0 volts Amplifier Module. This gives 0 volts output with no load on the load cell and gives a positive or negative output depending on if the gear knob is pushed or pulled.
4 Dual Input Amplifier Module. ECU input signal wires for up-shift or downshift are switched to ground at a pre-set trigger level depending on whether the gear knob is pushed or pulled. The trigger level is adjustable via an adjusting knob on the amplifier module.
Please note options 2, 3, and 4 require a 12 volt DC supply and ground connection.
IMPORTANT NOTE this gear knob is the latest far superior full bridge strain gauged shear beam not the INFERIOR bending beam system offered elsewhere for a lot more money
The Flatshifter strain gauged gear knob is supplied with an amplifier module which has normally open relays. The relay contacts close momentarily when hand pressure is applied to the gear to knob. The pressure at which this happens is adjustable between 1 and 10 kg using the adjusting knob on the amplifier module.
The amplifier has an output cable with power and ground connections and outputs from the relays. The thread for attachment to the gear lever is M10 x 1.5 pitch. and 7/16 UNF (m10 x 1.5 pitch £25.00 extra)
The relays are rated ay 1.5 amps and usually switch a 5 or 12 volt ECU output to ground.

We supplied 3 x Flatshifter “Shift” strain gauged gear knobs for 3 Mitsubishi lancer ex works Dakar rally cars , Owners comments below.
Hi Graham,
I think the best thing is that we totally forgot about them because we didn’t have any issues with them at all. I will look in our picture database and send you some of them. We don’t have any video because it was not allowed to carry an onboard camera during the stages.
I will check with RTL because we carried an onboard camera from the organization in one of the cars for a couple days.
Will send you more tomorrow when I am in the office.

Flatshifter “Shift” strain gauged gear knob on a race TVR
Hi Graham
we love the gear knob what a difference it makes to the gear change
I was short shifting along the pit straight at Snetterton. just to let the lads here the noise it makes as it changes gears
it’s a seamless change which not only makes for a better lap time but takes that shock out of the drive chain that you get as you let the clutch out with a normal change
no in-car camera at the moment but as soon as, i will let you have the footage

It worked great at VIR! We won both races and set a new track record by 1.1 seconds! (Expert system)
Feel free to use it or any of my videos for your promotion.
