K & N COLD AIR INTAKE INSTALLED ON 2025 RR WITH FORD PERF TUNE QUESTION

[calelvis]

ANYONE DONE THIS AND DO I NEED TO REISTALL THE FP PROCAL TUNE TO ADJUST TO THE K&N COLD AIR INTAKE OR WILL THE TUNE COMPENSATE AND ADJUST TO NEW AIR FLOW AND FUEL MIX?? THANKS!

ECU 'adaptation' function will learn/adjust within set parameters. Hard to say how long adaptation may take with existing FP tune loaded.
However, reinstalling software may trigger ECU to 'relearn' sooner just as it did going from stock to FP tune. Another alternative, go back to stock - - drive ~50mls or more, then reinstall FP tune.

thanks, appreciate your response and I did think about doing that seems like a reasonable way to get the tune to recognize the new air fuel ratio ..

There isn't a new afr. Just a difference in available vacuum at load and temperature when idling.

I have done the same mods and I get a pcv hose a disconnect code. Not continuously about every 10 drives during spring /summer. During the winter came on in November and not again till April. Any one have any ideas. K&N is at a loss. Light is a nuisance light no effect on performance
