I don't know but will be very interested in the info. Just about to buy some bosch 42lb injectors.

Can I ask where you got yours from?

Cheers,
Tom.

I would agree with Stevie. MS has something similar but generally its just default figures that you put in unless you know for a fact they are fast opening/closing.

Go with the defaults Tony. They're not super-quick, super-big or super-slow injectors, and unless they're all perfectly flowmatched (and "far too big") for the engine there's not a lot of advantage to be had from calculating any new values for the injectors.

They should be the ones in the config I sent you.

You will get an idea of how to tweak these from how the VE map looks after a bit of tuning.
