Hello all, thought you might like to see the small dashboard I made for my gear indicator. Three attempts before I was happy. I am really happy with my Interceptor. Done a few mods now.
I live in Cyprus, not a lot of rain during the year. As far as i know, I have the only one in Cyprus.

Nice work!.. Can you share some details, what, how etc.? Thanks.

I envy your location. Happy motoring  :)

Thank you. You are right. Reused an old smoked piece I found.

Dr Mayhem. I had an old photo frame with a smoked plexi glass front. Drew an outline round the gauges on cardboard and used a Dremel to cut out the shape. Took three attempts!!

Do you have a link for the indicator?

How the gear indicator works means where to connect which wire sometimes I forget to shift to 6th gear ????

So I'll assume hokey add-on with external sensors rather than internally wired to access ECU data

Looks really professional, can you give us some details about the gear indicator please as I would like to fit one myself.
Cheers.

I don't really need a gear indicator but I sure would like a simple light to tell me when I'm in 6th. Sometimes I lose track.

This is just what I need and have ordered one to fit over the winter. With the interceptor engine being so flexible and my other bikes a RE 500 Classic (thumper) and a Honda CB650R (buzz bomb) I regularly lose track of what gear I'm in.
Question, what happens if you miss a gear, ie. you have to take 2 prods to get it to engage, does the indicator then show the wrong gear. You move the lever, the indicator registers a change but you have missed the gear and have another go (it happens to me on the odd occasion)
All I can think of is that you will have to stop, power off, reselect neutral and start over.

If you have a reasonably accurate speedometer and tachometer, you can figure out your ratio.

Seems like a guy could paste a cheat sheet on his tank that shows rpm vs speed in the various ratios, until he trained his brain to just know.  The bottom line is that if the engine isn't in the rpm range that you want, you shift.  To my way of thinking, the only one position really need to be sure of is neutral.  I get a false neutral position between 2 & 3 on my 2012 C5.  Starting in 2nd can be embarrassing and hard on the engine.

I thought I needed a tach. on my C5 when I first bought it, but quickly realized that the sound of the engine is all the tach. I really needed.

I'm sure not enthusiastic about a gadget that counts shift lever pushes.  That seems unreliable as can be.  A gadget that is giving wrong information is worse than no information.  To reliably know what ratio was selected on a 5 or 6 speed gearbox, I think you would need at least 3 micro switches INSIDE the gearbox, plus a simple logic circuit.

To my mind, these gadgets, even from the factory, are just "sizzle" to sell bikes to the uninitiated, and one more thing to break, one more thing to take to the dealer for repairs, and one more thing to buy expensive replacement parts for.  I don't like power windows or locks in my car for the same reasons.

To know what engine rpm is preferred, it's worth taking a good hard look at your engines torque and HP curve.  For boat engines there's a 3rd curve, which gives fuel consumption vs. rpm, but that's found experimentally and only applies to a fixed ratio drive train and assumes consistent resistance ( not variable winds or currents).

I had this on my Yamaha. It calculates the gear via RPM vs MPH. It's not rocket surgery. I don't know why everyone doesn't do this. The inputs are already there. The one for the Yamaha comes preprogrammed but they can all be reprogrammed. Accurate to within 1 MPH. It doesn't work at a dead stop because there's no MPH to compare.

I should add that the real reason to put one on a Yamaha Bolt is because the stock speedo is invisible in daylight. I wouldn't pay $300 just for the gear indicator.

I do not have an interceptor but on previous bikes that had gear indicators it seemed to directly sense the correct gear to display rather than " counting" up and down from neutral.

I had this on my Yamaha. It calculates the gear via RPM vs MPH.

Thanks for sharing the link, an interesting gadget.  It has it's own sensor to measure turns of the wheel for calculating velocity, and senses ignition pulses to calculate RPMs via it's own sensor wires.  Then, as you said, gives gearbox position via internal calculation after calibrating in learn mode.  So, truly independent of the mechanical and electrical systems of the bike, other than requiring power.  You could even use it on something like a C5, which has a mechanical speedo and provides no tachometer hookup, although the C5's ECU knows what rpm the engine is turning via the crank position sensor.

Seems pricey at $299, but I'm sure a lot less expensive than getting all the required hardware and software together from scratch.

Hello Broher, can you please share details on how you connected the indicator?  The wiring diagram?  This looks awesome!!  Kudos to you

Hi Everybody
In case anybody is interested I have had this info re the Interceptor from Healtech


....This kit should work great with your bike, part no.:
GPXT + GPX-U01

It requires tapping 4 wires (power, ground, speed signal, rpm signal) with the supplied quick wire-tap connectors .
Here is the install manual:

I don't need no flippin' gear indicator.  If the engine is lugging and lurching or won't rev any higher or I just need more power or zip it's time to shift.  It isn't rocket science.

I wonder if these "figure it out by dividing rpm by vehicle speed" gadgets don't get confused if you are coasting in neutral and blip the throttle?

Jimku , you stole the words right out of my mouth. I don't have time to look at pie charts and graphs to work out which gear I need, simply feel and listen,  the old gal tells you whether she's happy or not.

It does but it's not like that's really a problem. It also stops working when you are stopped.

I'd say that there's at least a 50% chance the 650 ECU is already setup to read gear voltage and display it?

Yeah, some people just love gadgets.  I'm working on a butt-indicator to tell the rider his butt is in the saddle.

I thought that cars already had that feature and I believe some of them measure your weight to verify that you are heavy enough to sit in the front seat.  ::)

Yeah, my Kia has those ... to inform you that the air bag is active when someone is sitting in the passenger seat.  Maybe we need seat belts and air bags on motorcycles?

When running through the gears, up down up down, sometimes I lose track of which one I'm in. A six speed makes that worse because there's less to distinguish one from the next. Who cares if you are in third or fourth, but there have been a few times when I attempted to shift to seventh. Harley solved this by having a 6th gear indicator light. It saves wear on your boot toe.

I attempt to shift up from 6th all the time, especially because down here even our frontage roads are 65 mph speeds. I have driven a stick shift car for 25+ yrs, and currently drive a stick shift Subaru (not a WRX, just a stick shift Outback) with a gear indicator light on the instrument cluster. I don't need it. I have muscle/butt dyno memory of what gear I'm in, but I don't have that yet on the bike. It'll come eventually, I imagine. But a number/light would be nice.

Me, too, and it never feels like I've been working my way up through the gears when I do get to 6.
Gears 4, 5, and 6 feel short. Some sort of indicator light on one of the dials would be helpful.

With a bit of creative ghetto-modding you could easily get a fully functioning Apollo Command Module navigation computer onto the Interceptor.

Its the right period tech as well.
