Take off Rev Limiter?

Is there anyway of taking the rev limiter off when the car is in park?

you dont want to do that, you will hurt your car.

Revving the engine excessively while the vehicle is not moving (regardless of neutral or park gear) is harmful to the engine. You are making the engine operate without enough air going into the engine because the car is not moving forward

Not to mention when it is running, you are turning all the excess energy into heat and stressing components... Bye torque converter.

Lol, guys, I don't think he wants to rev it past 6500-7000rpms. I would assume he's talking about the (annoying and lame as hell) 4000rpm limiter when in Neutral and park.

OP, I also would love to be able to remove this. I asked OE about it when they tuned my ECU but they couldn't remove it. I'm sure they or any other tuner could adjust this but they probably haven't had it requested enough from customers to think it's worth their time.

Hopefully someone has a solution soon cause I would LOVE to hear what my car sounds like @ 7k rpms in park. It sounds amazing when driving but you gotta love a good ricer-rev every now and again!

Well I didnt exaggerate anything, I just gave him the facts. Honestly though I think he WOULD want to rev it to the upper limit, since thats when the engine/exhaust sounds the best, which is the entire point of revving the engine.

And I didn't say you exaggerated anything. But now that you brought it up...you are lol. I mean sure, technically you and your 'anti-ICE-revving' buddy in here aren't wrong, you're just being ninny's about this.

It's seriously not that big of a deal to rev the engine to the limiter.

Hmm. Wonder why MB put that limiter there. Auuume that torque converter protection was high on the list.

Yeah, I don't see how it's terrible for your car but if you were to request this then I would assume you would rev it high and often...

For the love of god all the guy asked about was how to remove the engine rev limiter not a lecture about thermodynamics

I have never hit the rev limiter in automatic only manual mode. I suspect there is a problem.

OP is talking about the rev limiter in 'Park' or 'Neutral' not when you are driving. If you haven't tried this, you will see that you can not free-rev the engine past around 4,000rpm.
