The biggest aspect to go to an oem ECM is when you consider that you can track them less complicated OR in view that they provide characters characteristics above and beyond the standard o.e.m ECM (solid band O2, consecutive injection, etc). IMHO, its unforgiving to conquer the share ECM (730 ECM) for tuning when you ponder how the it only leads about $200 to get the add-ons to song. You could always perk up to DFI (like the accel design) but what does it in point of fact provide you with above and beyond the stock options ECM .... .. not much ... except for which the you don't have to 'vaporize' a new promenade when you want to vary tuning. IMHO, only enhance the ECM when you need abilities above and beyond what the investment ECM can provide you (like wide band tuning). But, then you are referring to a $2k investment in a equipment like the FelPro.
