Mark, The link on your homepage to the EIS source is dead, as AOL's Hometown is long gone. Would you have any current contact info on them? Thanks, Bob

With the EIS, the sensor is a small black plastic box about the size of a deck of cards, which I mounted on the passenger side of the firewall. From there a 1/4" urethane line runs through a grommet in the firewall down to a little aluminum piece of 3/6" aluminum tubing (I think that's right) that I welded into the intake manifold about three inches downstream from the carb behind the the carb temp sensor. I've always had it, and it shows up in the MAP column data stream in the prop performance data at http://home.hiwaay.net/~langford/performance/ , in about the middle of that page, far right of the table.

Hey Mark, I didn't remember that you had a manifold pressure indicator. I ordered it this week. Where did you install the sensor pick up? I also don't remember you including the manifold pressure in any of the information that you have given altough I am certain it would be on the graphs that you have posted if I look. I still have not gotten around to flying with a laptop to record the EIS. The Dynon also records to down load but I have not bothered with that either. I tried to do a full throttle low altitude run yesterday but it was way to rough down low and I think that it is time to adjust the carb for summer time also because I couldn't get the exhaust temps to settle down either. I landed yesterday with a total flight time of 478.1 hours which is exactly 200 hours since the cam gear broke on the way to OSH 2 years ago. It also marks 200 hours exactly on Dan's BTA 5th bearing. Does anyone else have that or more time on theirs. I would like to make a decent formal report to Dan very soon. Joe Horton, Coopersburg, Pa.

I'm no Revmaster expert, but I do have a manifold pressure gauge built into my EIS system. The manifold gauge will almost never read higher than ambient pressure, so with a 30" limit, you'll be operating right around full scale deflection on the ground with the engine off, and near full scale at full throttle at low altitude, and less at less throttle or high altitude. Ram air will probably not make enough difference for you to even see on the gauge, so that's probably not even a concern. I'd go for a 30" personally, just for the increased resolution. Now if it's a turbo, that's a different story, but you'd have fried that gauge already. Let us know if you really do see much change when ram air is on or off, assuming you can control it, but it makes very little difference on mine... Mark Langford $13/Month Car Insurance?

Time to poll the collective wisdom of the list again! I have a Revmaster 2100 with ram air. The gauge in the airplane ranges 10-50 inches. I'm doing a panel upgrade right now and am wondering if I should change this gauge to perhaps 0-30 inches or some other range while I have the chance? What have been your extremes on your Revmaster? Thanks! Dave.
