The BC-5R can be mounted under the instrument panel or in an equipment bay. It comes equipped with a USB cable and data stick for accessing stored data.
The BC-5R incorporates an internal clock that is used to Time Stamp each row of data as it is recorded.
The BC-5R is capable of monitoring up to three Event Lines. These Event Lines are normally used to mark data for flight testing.
The BC-5R monitors and records bus voltage to the instrument.
The first seven channels of the BC-5R are configured to interface with Electronics International’s (E.I.’s) engine/aircraft instruments.
The eighth channel of the BC-5R can be used to monitor GPS data. This is normally Moving Map, Aviation or NMEA data. The data records are Next Waypoint Name, Latitude, Longitude, Ground Speed, Altitude and Track.

People [at EI] were great to work with.
MVP-50 is a really great product
Always built well. Always dependable. Been using & relying on EI equip for over 35 years!
Really glad to have accurate oil psi and temp! [It’s a] match with previous [EI] installs.
I won a FP-[5]L and had it installed in my c150. I was/am impressed with the accuracy and ease of operation of the FP. I wanted a new tach and I trust (and verified) that the EI R-1… would be my best choice. I am not a rich man. These instruments are affordable and incredibly accurate. Already planning my next buy from EI.
I have seen your products in other aircraft and have seen their reliability.
Nice bright display.
Love my new engine monitoring system.
Easy to install, and the CGR was set up to my aircraft’s exact specifications.
Your customer support is far superior . . . . I appreciate all your help.
[I chose EI because of its] reputation [and the] quality and appearance of the instrument.
Keep it up. I’ll keep coming back.
