    Default Tunning for 160# Bosch injectors

    I'm sure this has been beaten to death, but I am contemplating running the Bosch 160# injectors on my Turbo E85 car. Currently I have 120# injectors in and running decently.

    The advertised min. pulse width for these injectors are 1.6 msec, so in {B4003} if the value is below 1.6msec won't the injector stay shut? Or is there somewhere else to enter data in for the injector offset (ie time to open and shut injector)

    Also for the voltage adjustment, the data Bosch publishes does not take in account to manifold vacuum, how are most people scaling that data?Click image for larger version.

    Does anyone have a successful 160# injector tune they could post up?

    Thanks!

    What actual injectors are you using? I am in the process of switching them over in my truck for E85.

    I know this is an older thread but I was directed here by racetronix support

    The injector information posted in the OP is incorrect, that is the injector info for the FRPP 120# injectors part number # E303

    If anyone has any bosch info on the 160s please do post back or email me, email in sig
