Trying to figure out if the ECM in my 1995 F-150 is too old to hack and build cool stuff off of. Like on-board diagnostics. My worry is that it is too simple to be useful. Hard to find specs on the ECM. Thanks!
@Eric Bollinger 1983 - 1995 is just an EEC Test or OBD I code storage style diagnostic system. Not much to love for live or fancy reading there. Just the blinking CEL light flashing number of times for numerical code numbers.
