Hello everyone, while perusing the forums here the other day I came across a post that had some interesting claims in it. One that caught my eye in particular was something that I think the tuner scene would be very keen on knowing; and that’s
“ECU learn Down” and from what the poster said it’s exactly as it sounds, wherein after a few days of getting a horsepower or torque increasing modification, the ECU supposedly throttles the car back down to factory spec.
Is this true??? I’ve worked on cars my whole life and I’ve never heard (or seen from then on) a car that would throttle it’s self back that much, even with physical mods.
