Service Based Bypass is the bypass method best used when the bypass needs to exactly define at which point in the ECU’s data flow data shall be sampled and/or a bypass shall be triggered fully synchronously to a ECU function and raster delay shall be avoided.
As a consequence, each bypassed function requires its own ECU trigger, which can be a limiting factor in some ECU projects. This paper describes how the available ETK resources can be used in an efficient way.
