Just to clarify "ECU Tuning methods" for everyone. In days gone by tuners used whatever means necessary to install a tune product in to an ECU (engine control unit, also known as PCM, ECM, etc.). There are many types of ECU and circuit board configurations. It is fair to say that make, model and release date play a role as to which technology is made available to the manufacturers by the ECU suppliers (eg, Bosch, Siemens, Magnetti Marelli, and so on). Older ecus (in general) have a "plug-in' style of chip, which can be removed without need to solder for reading/modifying/writing. Some eproms are UV erasable and others are not. As ECU design progressed so did the need for more memory and processing power. Hybrid processor/eproms and PSOP chips became favor of the ECU makers. Cars that were not supported by OBD2/OBD1 read/write protocols usually needed to have the chips removed (de/soldering method) for read/write to the correct component/s. Progression to Processor controlled ECUs is now the norm in modern vehicles. Increasing requirements from the manufacturers for more advanced emission controls force the evolution of new design technologies. Tuning methodologies are forever changing. If you are an experienced tuner with knowledge of all ecus (past & present), then you know all methods to modify: soldering/removing of eproms/processors, OBD2 & bench (ecu out of car) "flashing", boot techniques, etc. In case of one method not working for whatever reason, if you know all methods (as a tuner) you can always complete the task.

Wow, I am a newb when it comes to tuning. Idk if this was answered yet, but if you have an E55 and a eurocharged tune (this is pure hypothetical) and want a RENNtech tune, can this be done by obdII or does the chip have to be pulled?
