Multiple Displacement Engines ???? adapt your own
As you may well know about the gmc MDE or something like that, Multiple Displacement engines. As far as I understand they take a v8 and under regular driving conditions they "turn off" four of the cylinders to result in improved fuel milage. When you step on the gas it "turns on" these cylinders for the extra horse power.
My question is how are they "turning off and on" the cylinders? Is it just switching off the injectors to 4 cylinders? and if so could I do this to my vehicle (wifes Ford Escort) with a dash mounted switch to shut off 1 or 2 injectors of the 4. I could switch them on when I needed them and off when I'm cruising under no load. It may or may not throw codes but I don't care.
I drive 120 miles roundtrip a day to work and I have alote of time to think
any thoughts???

GM and Chrysler both offer this on several engines.
GM calls it "Active Fuel Management", Chrysler calls it "Multi Displacement System".
If you Google those, you can see how those companies did theirs.
Ironically, Ford said back in 2001 that they would have engines doing this within 24 months. I think they're over-due.
