2010 i4 accord injector upgrade

Post by XxZorro13xX »

For my specific car/ecu injector sizing is still in beta. Is it possible to upgrade/change injectors without this feature. I have an RBC intake manifold and RDX 410cc injectors to go with it (not installed yes as in don’t know how to tune for injector changes) I’ll have a cold air intake with a ZDX/MDX throttle body. I am a beginner obviously, but I was doing some research and saw that injector sizing was a function but my ecu doesn’t have it yet. Thank you all in advance.

AFM.Fuel holds fuel injection times.

How would I go about properly tuning/changing these values from my stock 310cc injectors to the RDX 410cc?

You can adjust via percentage by highlighting the values and using Control-J.

So find the percentage increase of the injector and apply that to the AFM Fuel table?

If you have an injector that flows more you'd want to open it for less time to achieve the same amount of fuel. We can't coach you on tuning specifically, so I hope that helps. You can always reach out to a professional.

This have been, thank you. I just wanted to make sure I had a basic idea of what settings effect the injectors, I have changed the injector timing to the RDX 410cc in the injector dead times tab and reduced the AFM.fuel table by 24.4%. My last question is regarding the RDX 410cc dead time setting as it says "RDX turbo 410cc" does that mean the setting are for a turbo'd set up or? Just want to make sure I have chose the "correct as can be" option,

Battery offset tables are for specific injector brands/sizes. Nothing to do with turbo or not.
