Bosch may have an exclusive deal with Porsche because the version Porsche uses internal electrical values coincide with the electrical values the DME is expecting. One thing you need to recognize is that some of the aftermarket units may not be the same electrically, just physically, which could endanger the DME as they were designed for a different application. You need to decide if the cost savings are worth the risk................
