Anyone have any feedback (good/bad) on the Dinan Engine Software for the M5.\
Thanks,
Thanks,
I had it installed and then removed the next day. I really didn't notice any difference other than the rev limiter was moved up a few hundred rpm. But I did speak with a BMW NA engineer Tech Rep and was adised that regardless what Dinan publishes, a Dinan chip or software download DOES void your BMW warranty if any problems results from the Dinan product. Dinan allegedly warrants whatever BMW denies. But my contact says he has seen cases where BMW denies a warranty claim and points the finger at Dinan. Dinan then also denies the claim claiming it wasn't their product that was defective. Meanwhile, the customer has no BMW to drive while BMW and Dinan duke it out. I say stay away from such products as long as your car has factory BMW warranty.Originally posted by stevea1962:
