Ok so I purchased 420cc injectors and I have a few other parts on my car but I can't find on my flash pro manager a calibration for the 420ccdw injectors. So I installed the fuel injectors on and even had to fabricate each injector connectors and cut the stock ones off and wire the connectors that come with the injectors. And cone to find out there is no cdlibrations for these. I had to use the 450ccdw calibrations and I'm having more than 50 knock counts each cylinder when I get on it.please help asap I can't even find calibrations online for these injectors or anything.

Knocking is most likely caused by ignition timing and not by fueling unless you are running dangerously lean.

Well I thought to input the tune for the closest size injectors and it is the 450cc. And I have the 420cc injectors.

What all do I have to play with in the flashpro manager.i mean other than changing the size injectors in the fuel Input.

You will need to change the dead time, and also adjust the fuel tables as needed to properly tune it.
