Injectors are Bosch motorsport greens, 42lb/hr 440cc's

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.

company called 50 motorsport in the states found them on ebay,
emailed them and more than happy to send to UK,

Thats one for teh VEMS people.

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.
