Hey guys, newbie question:
I understand the PCM, it's maps of fuel-air ratio and ignition, etc., and the OBD-II system. I've used code readers, and I know many will read the parameters from the sensors in real-time (rpm, air flow, coolant temp., exhaust o2, etc.) but are there any units that will do all this and reflash the pcm, too? Also, which cars can do PCM reflashes, and which ones do you have to replace a chip? Thanks!
