Chip Tuning

Can a car ever be powerful enough? As far as we're concerned, ‘more is better’. Here we investigate how chip tuning (after all, we are an electronics magazine) can improve the performance of our sacred cow. Our testbed is a BMW from an enthusiastic reader and we've also made use of the OBD2 analyser that is elsewhere in this issue. We won't give anything away yet, but the results are worth the effort!
