| 摘要： | In the early days of EFI, and OBD-Ⅰ, there were no real standards for getting data from the ECU. My brother and I raced a Honda Prelude in the IMSA Firehawk Series for showroom-stock cars that were modified for safety and that's about it. You weren't allowed to make performance modifications outside of the stock specs. But some teams figured out how to skirt the rules and modified the baseline ECU maps by having them reflashed to specific parameters such as removing the rev limiter or advancing the timing for a certain rpm range. The GM cars that raced in the series had a distinct advantage because they were equipped to connect to a laptop through the ALDL port (the DLC before OBD-Ⅱ). This allowed teams to make adjustments at the racetrack with a few taps on the keyboard; it was mind-boggling at the time. Honda teams banded together to swap ECUs as some were reflashed and worked better than others. However, we weren't able to change anything on the fly like GM teams. |
