BTW what tables/what latency did you use?
I still can't get why the latency I measured is that high comparing to lower CC injectors. The first picture/table is the results I got with DIY injector driver, the second table is what I got with the busa's ECU driving the injectors (with modified FW).
I used same fuel pressure (at least as indicated by the same fuel pressure gauge), same fuel pressure regulator, same fuel rail/hoses/etc. Gasoline is different this time though.
Few days ago I did a test, supplied the injectors with 14v, used fixed latency of 0x3c (1-to-1 what I got for 14v voltage), then corrected injector pulse with by making it about 3.8 times shorter and the bike was idling just fine, probably a bit leaner than with stock injectors (later I switched back stock injectors to test cold start/warm start and logged AFR). That's with literally no IDLE/IAP maps adjustments. Thus it seems what I got (at least for my set) is pretty much spot on.
