hello all,
so i have in my greedy little hands an AP engineering power FC for rb20. will this run my rb25? i hooked it up, and the engine runs and idles super rich. i guy i bought it from said it was running an rb25 in the car he had back in japan.
i know the AP versions are modified rb25 power fc's, but does anyone know what the differences are? will i still have full functionality and tuneability with this ECU?
