Rev it up?

Just noticed something after a year and a half. Tried to rev in neutral and would not go past 2500 rpm even if mashed to the floor. Could not get past until reaching operating temperature. It was 70 degrees outside! I am guessing Canbus and fly by wire throttle? Just curious.

many manufactures do this to prevent the engine from being over reved in neutral. High revs without a load on an engine can hurt it.

i guess we have a rev limiter. I believe we do have some sort of engine management system in the market to bypass the limiter, but then again...our jeeps aint winning any drag races.

You gotta be carfull going over the set rev limit. many manufactures set the rev limit close to the max piston speed the bottom end can handle.

Yeah. I wasn't trying to hit the limiter. Had the door open and just wanted to goose it to hear stock exhaust.
