Been looking at the Datamaxx units as well. Same issue I think...I would need their dash to see the data live.
Both are pricey, and if RP sensors fail with that kind of regularity, I would probably go thru the roof spending that on it to have it fail...
That's all my Autometer stuff did was quit on me....
I bought the cheapest Sunpro crap I could find the last time out...Two seasons and still working....I think all the gauges are made in the same factory these days regardless of price..
If I spend the coin, it has to last....Or be cheap enough to carry spares.
