The E/K Display

Make your Fuel Data display useful after an engine swap.

A stock-looking solution that provides engine data in place of your defunct 'Fuel Data'
display. Plus it controls torque converter lockup and alerts you to 'out of bounds'
conditions. Works on V6, Diesel, and '79 Eldos, too.
