Well i can't see the fuel gauge or gear position working on these. which is a shame considering the price. Also does not mention a clock either.

I can't see this being plug-and-play either.  Especially if you want all the other idiot lights to work as well (low oil, check engine, etc.).

Me thinks this is going to be a complicated install.  I hope someone (Pete) proves me wrong.

Well, I think the idea is that this is much more than just a tach.  If you can get all the features to work with minimal wiring and without the addition of senders, etc. that is.

For just a tachometer, I'm quite happy with my Daytona and the install was relatively easy and truly plug-and-play.

Hope to find out soon enough.  If,for the price, I need to add additional cables, wires, mounts, etc, Iíll just return it.  But if itís true plug and play, then Iíll be happy to gain the functionality for the price

Cvvmax showed that there's a varying resistance as the fuel level drops so a gauge would just use different resistances to control each lcd segment.

The tach is easy so gear position is calculated from mph/rpm.

The variation in resistance only registers when the fuel is low, ie below the sensor.   so it will not show different levels. IMHO
 As for the gears it might work like that but i really doubt it all the bikes i have had with gear indicators do with it a sensor in the shifter and that is why it will show what gear it is in, even when parked with just the ignition on and engine stopped.

And soon we will all know, aye Pete :)

UPDATE   I just went to their site and this tacho is also shown in the gear selector section also, so i spose it must have that function as well, oh well have to wait and see,

Cvvmax claimed that at just over a half tank of fuel would trigger the low fuel light when he used the V-Star speedo. He also measured usable resistances above that level as well as below the 23% stock trigger point so the range should be better than expected.

I remembered reading this particular line in one of cvvmax post which is why i wrote what i said in my post,

 [ Then when the fuel level goes just below that set level, the thermistor starts to come out of the liquid gas and changes resistive value which will settle down into a resistive window of a a few ohms +/- from a resistive value which the meter expects to read...]

THe whole topic is here  https://www.yamahastarbolt.com/technical-discussion/analog-speedometer/

Anyways looks like i'm wrong... i thinks :) Always a first time

I can rewire a motorcycle or airplane - but when Art got into that - it went over my head like an SR-71 at 85,000 feet.....  ::)

To hopefully get an answer before I drop $$ on the koso meter, I emailed them to find out if any additional adapters, wiring, harness, mounts were required to get the tach, gear indicator, fuel gauge to work.  I'll let you know what i find out. 

If there is a need to go through and do anything other than "plug-n-play", i wont waste my money on this.

So I just talked to the tech department at KOSO.  He said that the tach function is already stored in the ECU, so it will display right away.  The fuel sensor is also stored, and should report after a fill-up, or at the very least indicate the level when the fuel light come one.  Also, the gear indicator is a "learned function" of the meter, so it will learn what gear you are in and store it. 

Ordering mine today or tomorrow.

Thanks Pete.
Keep us posted with any "gotchas" or hiccups when you install it?
