I’ve been flying for 30 years and never experienced a hiccup from an airplane engine while airborne. That changed a few minutes into a recent flight. This story can’t rival a sudden engine stoppage and forced landing—it’s a story of an engine that seemed on its way to quitting—but I…

I have 60 hours on my JPI900. It is all I had hoped for and eliminates the problem with replacement transducers for Mooney aircraft. This replaced the JPI700 I had in my 89’Mooney 201. I made a new panel to accommodate the 900. It is a great unit and product…

BetterAircraftFabric I have one of them on the turbocharged 6 cyl Continental and I would not fly without it. – If a fuel injection nozzle plugs up on a turbocharged engine a certain disaster is going to follow and the instrument is basically the only real warning one will have…

Donna,  We spoke yesterday on the phone. I purchased a JPI-830 last year and had it installed on my Maule M-5-235 after I had the engine rebuilt earlier this year. After having the work done I flew the aircraft from Seattle up to Juneau, Alaska then for the following 3…

Dear Joe, We have installed the EDM-790 and flown about 20 hours so far.  It’s pretty cool.  Still learning all the features but we are seeing serious fuel savings – about $100 a night.  I’m working with GAMI to tweak the fuel flows a bit more.  The data download system…

While looking at your web page it occurred to me that I owe the company my appreciation for avoiding a disaster in my 421C. Some years ago I put dual JPI slimline tach and MP gauges at the bottom of my panel.  Though I have had some issues getting them…

I was headed back to the Pacific Northwest in my 89′Mooney 201 from southern Florida. Shortly after takeoff the EDM 700 was showing the EGT on cylinder #1 was running 240′ hotter than the lowest EGT reading of the other 3 cylinders.#1 CHT was slightly south of 385′. I watched…

Dear JPI Folks: I replaced my EDM-700 this weekend with the EDM-730.  I had inherited the unit from a previous owner and although it worked just fine, I was intrigued by the larger color 730 version upgrade (actually, I couldn’t resist).  The install was uneventful and – as you said…

Dear Mr. Polizzotto, I have a EDM 700 in my aircraft and began having dimming issues with the display. I spoke to you at Sun N Fun and you asked me to send it in for repair/update at N/C. I received the repaired instrument and everything seems flawless. I wanted…

Dear JPI: At the urging of my mechanic  we installed your JPI700. I had used a competitor’s engine monitor, but found lean of peak operation exceedingly difficult and engine performance data limited. Within the first 20 minutes of my departure for northern Canada (i.e., Cambridge Bay, NU, Inuvik, YK), the…

Dear Joe, I currently own a Christen Eagle which I have been displaying and competing with over the last few years. The modified Biplane performs incredibly well, but it has been a rollercoaster ride with the authorities here in UK. There is still more to do (New wing and colours…

June 4, 2010, my partner in our 1979 PA-28-236 (Dakota) Richard Klein and I, as is common for us, left KDXR to practice some instrument approaches. I flew first and did the ILS 6 at KBDR, followed by the ILS 36 at KOXC. We pulled off the runway at OXC,…

Dear JPI, I recently installed an EDM 930 in my Beechcraft Sundowner.  It is one of the best things I’ve done. The peace of mind, the improved situational awareness, and vastly improved engine performance make this purchase worth every penny. While most other pilots only guess at their fuel quantity (seldom…
