Have a 1986-1990 2.5L or 1987-1990 4.0L Jeep with Renix EFI and 15 pin Diagnostic Port? Old Jeepers unite, the REM is here for your diagnostic needs!

The REM is a Plug-and-Play homebrew scantool decked out with the latest tech to read in your Renix Jeeps Engine and Transmission computers’ data for a wealth of information on all the various sensors and readings throughout! A Check Engine Light has been added to alert of possible sensor issues or failures. By combining Transmission and Engine data you can even keep an eye on fuel economy! With included USB port or Micro SD card slot, data logging will be available to diagnose troublesome issues off vehicle as well.

But I couldn’t just stop there; this Open Source and Mod Friendly device is fully compatible with Arduino and includes a wealth of bonus features like a 3 Ch Fan Relay Controller, Analog Voltage and Resistance Reading, and a Signal Generator for low level piggyback engine tuning! A lot of new features and software are constantly being developed to create the ultimate car-puter device for your old Jeep!
