Need help to fuel pressure
I am making some mods to my stock RXP, my mods right now are as follows:
Solas 14/19 impeller bran new
SS wear ring bran new
4® front mounted air filter kit
Blow of valve Kit
Rotax Racing ECU
through hull exhoust
And ofcouse a rebuilded SC but with stock impeller
I guess I will need to go with some bigger fuel injectores, but I have in mind maybe to do some more mods later. Would you advice me to go with 42 injectores or a fuel pressure regulator ? I would prefer a fprr but I am not sure how to adjust it as the engine is running correct. Ofcouse I would like to advoid a too lean mixture.
Anyone who could tell me how to adjust it right ?

you better handle the valvetrain BEFORE you worry about the fuel...
What is the RPM you are shooting for with the ECU ?

No more than 8200-8300 in the beginning. Later I will upgrade the valves and retainers but not now. Can I controll the max RPM by the fuel pressure since you ask that way ?
