EGT install

I've noticed I'm having the same problem as Rotax, stock tach and gauge aren't in sink.
They are up to about 5 or 6000 then it seems the gauge is almost 1000 higher than the tach???
I tied both orange and yellow wires off the gauge to the VR.

When I had my Avenger III gauge on my 07 this is how I wired it and everything worked correctly, the tachs were a little off, but not that much.
Avenger gauge has 3 wires, yellow, red, and black on mine. I taped the yellow wire into one of the yellow wires out of the regulator, red wire was into a hot fused wire, and the black to a frame bolt. Just how I did mine.
 
Does it matter that I tied both the yellow and red wires to the VR??
When I say that I mean I actually twisted the 2 wires together then tapped into the VR wire.
 
Issues

Well I got something screwy going on.
Sometimes the RPM is right on and very close to the tach readings and sometimes it's 1000 high..or higher and the numbers really seem to fluctuate more.
 
same deal...but guage stays on so i dont care, at wot they seem to show me what i want. thats only time i spend much time looking at it anyway. and mid range for watching egts.. and cold start coolant temp... dgas about the idle rpm flucuations personally as it seems to read proper at higher Rs.

If mine was right at WOT I wouldn't really care either but I got warning lights going off saying I'm hitting 9000+ but the tach says 8000 and the motor doesn't sound like it's reving higher than normal.

Crusing down the trail at 6000 but the Digi says 7000+ and if I blurp the throttle I'm hitting 9000 and my warning lights are going off.:mad:

Weird thing is on a climb though she seems to read normal.

I know part of the issue is track spinnage when on the trail but 9000 and even 10,000 RPMS...ish don't tink so.

hmm, have u played w/ CAL settings, it took me a while to finally get something that worked right on mine. i'll check what mines at tonight..
 
As far as I know all Rev's run on CAL 6.
The only thing I can think of is either I have a lose connection or it's the gauge, cause like I said one min. it's fine and the next it's 1000 high.

Rotax, did you connect both orange and red wires to the yellow VR wire?
 
red (power) is connected to accessories (NOT VR).

orange (tach pickup) is connected to the wire that runs to the guage (white/green??)

i SOLDERED mine in, after getting upset w/ the hockey crimp connection...i quite dislike those things for any consistancy, specially for a vibrating snowmobile!

My Digitron rpm is out from what my factory tach says unless I turn on my hand warmers and then everything reads fine, there must be to much voltage with all the accessories shut off.
 
digatron hookup

I had the same problem with my hookup so I just disregarded wiring the power into any wire and just hookup up a little 9v battery to my guage. I think part of the problem with this system is the fact that the voltage is always changing. I was getting only about 1-2 volts at idle but it would go above 12 during higher rpms. Part of my problem is probably that I don't have many things running to draw off the excess power (I only have a little fog light for a headlight and led's for taillights and my handwarmers aren't hooked up right know). When I wired it with the closed circuit, everything works fine. I just need to replace the 9v battery every couple of rides and make sure I turn it off when done. Has worked good for me. Kevin
 
Here are the instructions that I used from Digatron Direct, I am also only running a LED taillight.

"Gauge harness installation and connections. The Rev uses a DC electrical system. When ordering your gauge make sure you specify a DC harness. Attach the Digatron harness to the following wires on your sled. Digatron Orange wire to the White/Green Stripe wire located on the Speedometer connector (#3). Digatron Red wire to the Aux Power harness' Red/Yellow Stripe wire. Digatron Black wire to the Aux Power harness' (#4) Black wire. The Aux. Power harness is a three wire connector located immediately next to the Speedometer Connector. Solder all wires for a good connection. Route wire up the steering post"
 
Right, I know what the instructions say but I heard of people having problems with it wired that way and people suggested wiring it directly to a VR wire so that's what I did.
Maybe I should try wiring the red wire to the Aux power, or is that how you have it and your still having the same issue??
 
I haven't tried any other ways but I wonder if a person could put a resistor on the power supply so that it wouldn't get the high voltage in the upper rpm.
