Hey folks,
I put some freshly rebuilt NB2 injectors into my Miata before I started tuning the MS3.
I used 265cc/min as the flow rate for calculating required fuel. However, I just found the report from RC Eng and they indicated that the flow rate of the injectors on their test setup was ~280cc/min.
Should I update the number for the required fuel calculation, or is the standard 265cc/min number more accurate for real-world conditions?
Thanks

I'd probably leave it at 265cc/min. There might be a difference in fuel pressure between their test rig and your car which could account for the readings but even if not and your injectors really do spray about 5% more fuel than they're intended to, when you start to tune, the VE table created will contain the correction needed to make your injection pulses right.
