I to spoke to the factory today regarding the upgrade/rev hang remedy but at a cost of £2135.40 will try to get used to it for a bit longer.
I am struggling to get my head around this having spoken to Adrian about the issues of rev-hang he had on his 3.7 Roadster.
Please correct me if I am wrong; but a customer will spend £48,000 + on a new Roadster and then have to pay an additional £2135 to get the ecu sorted (sorry "upgraded") to an acceptable standard?
