I came across this searching for something that will work with obd1.
Except this has 4 analog inputs with the ability to program look up ables. + 2 egt sensors.
Custom alarm/warning light
Relay external switch option for thermo fans or water sprayers (anything really) to switch at where you program it to.

Pretty neat. well priced.
