I'm looking to buy an R8 and I am at the research stages of the purchase. I did have one question I wasn't really quite clear on. It seems the R8 Plus has a different ECU tune, slightly different gearing, and a spoiler. Everything else seems to be identical, so if all that extra horsepower is generated from the ECU why can't the ECU of a non Plus just be flashed with the Plus, or just replace the module? Please enlighten me. Thanks.
