Any updates on the tach accuracy? I am debating getting one of these.

Thanks

As far as I am concerned, there are no updates. I tried to reduce number of windings around ignition coil, no change. Values inaccurate, no matter how I connect sensor cable. But definitely works as intended as engine on detection.
However, I strongly suspect this is an issue with the Yamaha WR250R and may not at all be an issue with other bikes.
And apart from that, even with mistaken tach values, the Voyager is a lovely device that I really appreciate. I would simply go for it. Take care to buy a FW-2 device! FW-1 is outdated and lacks several important features and some usability.
Have fun with it!
Phil

Somewhere in this thread is a mention of adding a 2.2K ohm resistor in series with your signal source. I use the low voltage coil terminal as my source and adding the resistor was a definite improvement. This is on a first generation Voyager set for tach/2 on a two stroke enduro machine.

I put a resister in line with my tach sensor and it really cleaned it up, I don't remember the value of the resister at this moment, but I always suspected that the wire was picking up some extra signal from somewhere and was going to insulate the wire but I haven't gotten around to that yet,

Tach reading should be fast, accurate and stable. If you have tach reading problems, contact us and we will get your unit back in for update. contact chris@trailtech.net or just give us a call and ask for tech support.

Pulled the trigger on this unit and looking forward to it.

Stand by for questions! I may need support!

Thinking of getting one of these myself

I'll use it along with my Evo phone with the Back Country Navigator app which will provide topo backups (and already has my route loaded into it).

I'll keep the Evo packed away safe in a Pelican box and only pull it out if needed. I'll also carry paper maps and a regular compass for rides in new areas.

I see the overall convenience of this, but also get the need for real map data when things don't go as planned.

When are you going to incorporate this bar graph tach?

Tach acuracy issue

There is some update now on the tach reading at Yamaha WR250R:
accidentially I found out some interesting thing today, when I suddenly discovered, tach reading was perfectly acurate when returning from the shop where I had the 30.000km service checkup done.

My first thought was they had fiddled with the sensor wire somehow.

Wrong.

They unconnected vehicle power!
My voyager was plugged into parking light connector for charging. The shop had reconnected parking light, leaving the voyagers connector unplugged. I found out when suddenly I discovered the 0 value at the input voltage display field.

As soon as I reconnected vehicle power to the voyager, tach values got totally garbled immediately and voyager started charging again with correct input voltage display.

Can someone from trail-tech comment on this? I can reproduce this behaviour as often as you like :)
The correct sensor setting for tach sensor at the WR250R btw is 1/2 PPR (peak per rev).

Kind regards, Phil

I got weirdness on my Vapor tach when vehicle power was on an A/C line.

In my case it is definitely D/C, 12V. I eventually connect my Garmin 12V->5V USB converter cable to same outlet and it works perfectly with the Oregon GPS. There is nothing special about this power supply. However, the Voyager refuses to get tach reading acurate as soon as it is connected to this source. I have been using it for probably 18 months now. It took this long until I found out about it

sounds like the CDI and the battery don't share the same ground.

Thank you a lot! So, next step will be to connect Voyagers external power differently. Maybe use ground wire from ignition coil? In a first step I might try wiring it to the battery directly and see whether things change.

To me this means there is no systematic error. It could definitely work well and perfectly acurate with the WR250R.
Worth of putting some more effort into it.

Thanks for your helpful hint!

Phil

garridan, I see you have this service notice on your web site, does this mean that all new Voyager's come with the tach bars?

FW 2.07.04 out: http://trailtech.net/voyager_software.html

!!!IMPROVED TACH TIMING ALGORITHM!!!

Woah, lets see tonight :)

[BTW, just some report: my previous tach reading issues could not be fixed by using external power supply from battery directly instead of parking lights connector. See my previous posts here in this thread just in case.
It is not related to power source used, but to the way, the ext power wire runs through the harnish. Even when ext power is cut off, tach reading is rubbish as soon as ext power wire runs into the other wires at front mask. However, it will become acurate when isolating power wire completely. This means, that for my case with the WR250R there is no possibility to use external power AND currect tach reading together. But I am no longer hopeless, since this new FW has been released]
