still reading...still learning about these lil 98-2002 cav 2.4l engines....LD9
is it true that the ECM needs to be programmed if I get another 2.4 from same year and swap it?>>> how will it know I did this?
"This engine received a minor update halfway through the 1999 model year that eliminated the exhaust gas recirculation, increased the compression ratio from 9.5:1 to 9.7:1, and switched from low impedance fuel injectors to high impedance. For increased reliability this engine also saw other minor updates in the 2000s towards the end of its use in General Motors vehicles. In 2001, changes included a smaller knock sensor, flat-top pistons instead of dished, new oiling passages, newer stronger timing chain, a newer-designed water pump, a redesigned starter motor and a higher capacity catalytic converter. An improved belt tensioner was introduced in 2002."
so.....IF I re-built same year engine, and flip it in....anybody?...will the ECM be usable?...or will I have to send it off to be re-programmed..(read $200bucks!)
