The software receives the data which is the ROM and allows us to modify it and change it as we see fit. The ECU Flash program communicates with the Processor of the ECU to request a dump of the content of the EEPROM through the OBDII communication port. This is a system requirement for the sole purpose of emission control and updates. It was implemented in some early model cars in 1994 and eventually was standardized in 1996 on the OBDII which is the current standard on all our vehicles. The ECU uses a memory called EEPROM which stands for electrically erasable programmable read-only memory. If your one of the happy lucky people your in for a treat and some fun. Might have a Processor which currently supports only downloading the ROM. Has no pre-cats and no O2 sensors in the exhaust manifold. Your odds are that you have a currently supported Processor that we can Flash. Has 2 pre-cats and 2 O2 sensors(Front and Back of the engine) before them on the exhaust manifold. I don't know exactly which Stratus Years that are actually flashable but: **If I'm missing any Processor Family post them up so I can update it We are currently able to download but not flash back: * Mitsubishi and Other Roms = Various ROMsĬurrently with the latest version of ECU Flash 1.34 we are only able to flash: Restart the software to allow the new definitions to take effect.

This will also technically void your warranty if you visit the Dealership and they check your ECU for codes. There is always a cost, but when things are done safely and realistically you can achieve great results too. Tuning can be dangerous and cause your engine to fail or damage, harm to your self and others, including death. Here is a post I did on the 2gstratus with all the files and things all put together somewhat like a how-to but without the tuning stuff.
