When my mate first received the speedo it was flashed to 508 for running at the club, it was then re-flashed to a stock software (don't know which one) and it was re-flashed when he was out racing last week by a local guy to 323 stock as he was having some problems with his new motor (x12) and now it won't reflash. Any ideas?
