I just got some bigger injectors and I need some help from someone who has bigger injectors and adjusted the parameters using S-AFC. I have not put them in yet. Need some starting point on settings. They are 550cc

1000RPM, LO setting, -50%

That's a start.

They are 450cc not 550cc. Mess up in typing.

if they are actually 450cc, they very likely will not work. i know RC engineering does not make a 450cc saturated injector, only a peak and hold. Our ECU can't control peak and hold injectors. They do make 440's however.

If they are 450cc injectrs from a turbo dsm, they will not work, as they are peak and hold.

I thought the same thing so I called HRC. Where I bought them and they said they are the correct injectors. THey said I might needed to buy a nozzle restrictor. For idle pressures. I don't know. Is there any one who has made injectors this size work?

i run 440's, it's perfectly fine.

I know OF people who run 550's, they're fine too.

It's not hard to make them work. I still run the stock base fuel pressure, too.
