Morning all, I've just fitted my DIY fuel economy computer (an "MPGuino") and am looking to get the second of the two values it uses (injector uSec/gall) dialled. I've done some searching and it has been inconclusive. I'm currently using 22lb/hr as my starting flow rate as that's what a US site quoted for a C220 - nearest I could find. The other number that keeps popping up in specs is 166ml/min. Does anyone know a definitive answer?
