I haven't looked at SOI parameter, but it does make sense that the injection window would be (SOI - spark timing). We'd have to assume that SOI and spark would be referenced off BTDC in the ROM.
Does anyone have the RAM address for SOI?
Kodename47 has had up to 5.8ms on the DI injector - anyone else gone higher?
