Last year I bought a ScanGauge but didn't get to use it very much before I put the MH in storage for the winter. I have a 2005 Fleetwood Excursion 39S with a Cat 350 C7 and Allison. As stated, the engine is rated for 350HP, but I don't think I ever saw the ScanGauge read over 265HP even when I had my foot down going up hill to see what it would read. The engine runs strong, but I thought it was odd that I couldn't get a reading over 265HP? I wasn't expecting to get a rating of the full 350HP, but 265HP seems low to me. Has anyone with a ScanGauge checked to see what the max HP reading was they could get?Bill

Horsepower can be adjusted for accuracy through theAdvanced Setup parameters. -Tom

It's just a rough measurement on its part based on a number of parameters. It doesn't actually measure it.

Tracrig, I contemplated getting the ScangaugeD for our Itasca Horizon 36GD with the 330 CAT when I couldn't read the Medallion Information Center LCD screen due to it being so dark. The Scangauge does just about all of what the Medallion factory info center does and, a bit more. In reading the specs, it, as you've seen, "claims" to display Horse power. Well, I'm not any form of an expert here, especially on CAT engines but, correct me if I'm wrong here but, I'm always under the impression that in order to get any form of a HP reading, one needs a dyno to do that. I've talked with a few on that and, most agree that the Scangauge really doesn't have the ability to correctly read or, produce HP readings accurately. I could certainly be way off here and, maybe some of the users can figure out a way for it to produce an accurate reading, if it's possible that is. But, I chose to order up the newer version of the Medallion Info Screen and see how it does. Good luck.Scott

My Scan Gauge is on my Ford 362 HP gasser. I've never seen it read HP more than about 190 at crusing speed 65 MPH. My engine doesn't produce 362 until 4750 RPM at FULL load( petal to the metal). I've never had RPMs higher than 4000.

This is the OP.I don't remember what the RPMs were when I was looking at the HP reading. I'll get the MH out of storage in a couple of days, I'll take a look at the RPMs them.Bill
