In an open tuning environment (when people can make any change to any part of the ROM), there is an inherent risk with allowing for partial writes. This is not an issue when you are operating in a closed environment which, in a sense, can protect you from erasing/moving code necessary for communications. Until we can assure that there is no risk of a customer bricking their ECU, we will write the entire ROM. Yes, it takes a 3-4 minutes longer than doing a partial write. But it's a lot safer and will undoubtedly keep people (including some tuners) from disabling vehicles. These are all very big concerns for is given the scale of our customer base. We do encourage customers to custom tune themselves for with the help of experienced tuners. But along those lines, we also implement safety protocols to minimize (not to eliminate) risk of nonrecoverable hardware failure.
