I just performed the wastegate retrofit conversion using ISTA/P on my E90 335i. Now when I start the car it idle surges very badly and is reporting limp mode. The only thing I notice in the report is that there are warnings to "Reset of digital engine electronics adaption values and variant" and "Clear fault code memory". Other than that the report is OK. Do I need to clear adaption values or reset the ECU manually? If so, how do I go about this. The car won't drive past 1500 rpm like this!
