DynoTune Boost Gauge Issue
I have been using my DynoTune boost gauge since I've had the ski, it has worked fine, at idle it always reads between -8.9 and -8.1 vacuum. Well today I started the ski up on the trailer and the gauge started off at 1.2, then kept going up and up all the way until 25.6, and kept increasing. Anyone have any idea what could be causing this? There is nothing about it in the DynoTune manual, and the guy I spoke with said he's never heard of that happening and didn't offer me any solution....

You got water in it. If you dry it out soon it should be fine. Just remove the bezel & hit the inners swith some compressed air & let it dry out somewhere with low humidity before putting it back together. It happened to mine several times, no matter how well I sealed it. Once it was reading 165psi. If it still doesn't work, I think they will replace the electronics for about $80 if you send it back to them.

Hmmm-since we are on this subject--I purchased a new blue dynotune gauge for my 2008 RXT-X. This is not my first time with this type and brand. They worked fine on my other skis. After hook up--reads vacuume as its should up to about 6000 rpm--then goes into boost mode. Well--it will only read 1.5 lbs boost with a high of 2.8 lbs of boost and it jumps between these two readings. I dont have a boost leak as I can pull 8100 plus rpm at about 73 plus MPH with my current set up. Called Dynotune--they said they had never heard of this. Told me to hook up my air compressor to the gauge as see what it reads. Well --did that and gauge would read up to 60 PSI.
At Dynotunes request--set gauge back to them--they tested--said it works fine. Installed gauge again--same thing. Anyone have any ideas--thanks.

I have buddy bearing caps on the SHO gauges on the boost and the a/f so when not in use i just cap them. And also before i installed them i seal every were water can get in top and bottom.

The Dynotune hates water. I had to send one back as well cause I really killed it in the open waters. Now I wrap the thing in plastic wrap like you would for your favorite sandwich and with a few tries usually get it perfect. Then screw the top bezel on. Has worked like a champ since I started doing this. Might be worth a shot for those also getting them wet.
