Boy quite the article, I'd say it's safe to assume both systems work well, I've got the UBG-16 with data recorder, Carb temp module, and the RPM module. I also have the FP-5L with egt monitoring and it's been interfaced with my Garmin GPS. I also have the RPM, Volts/Amps, oil pressure/temp. Yes, the panel dimming and hooked to warning indicators. I did most if not all of the work, IE wiring and setups,, "under the watchfull eye of my AME. I've downloaded, flipped and tracked and you name it with the data recorder. I've found these puppies to be very easy to install and about as simple to figure out as shifting gears in a car. I would imagine the JPI stuff is as simple to install as I've looked over the install manuals for them as well. Probably the analogy would be Fords versus Chevs. The reason that i went with the EI's as compared to JPI's, it boiled down to customer service. When I was doing some research to determine which ones to go with,, EI was very helpfull, whiles JPI was like trying to talk to someone about the MX 300 navcoms. I think we know what thats like. Yep, I've since punted the MX and have gone with a Narco,,

Anyways Bill, both probably work as well as each other, and both probably fail as often as each other. Just like Fords and Chevs,, Pick the one that you like,, and go for it,, either way, for the info you get from them, they are very worth it,,
