yes. and for a reason.

I can't pass the 4500 rpm also in park. My wife MDX has no problem to rev over 7000 rpm in park. Why happen to TSX only?

I have no clue. I'm kinda wondering the same.

How about RSX & civic Si? Does it happen to K20 engine also?

The TSX has a drive-by-wire system which basically means that a computer controls the throttle. You might want to floor the pedal, but the computer will override it and limit the revs.

IMHO, people who like to rev their engines need to grow up. There's no need for the car to reach its maximum rev while stopped.

Non drive by wire cars have rev limiters too. Either cutting fuel or spark.

You've obviously never driven a high performance car nor drag raced anything ever.
There are tons of reason to rev up a car & dump the clutch.

Not everyone is as passive as you are.

The low rev limiter with no vehicle motion is usually incorporated to prevent drivetrain breakage.
Releasing the clutch while the engine is revved up shocks the drive train even on a stock car.
The rev limiter reduces warranty claims.

Sticky tires with a 7000 rpm clutch drop REALLY shocks the drive train. Go watch some street drags & you'll see that most of the breakage occurs at the launch pad.

But i think the Rev limiter is only on AT's. But one of the main reasons is to assure that you wouldnt have major engine problems revving your car at red line all the time. But when you rev a tsx at 5k it sounds pretty good =]

Its normal but I think it's only for AT..

No happens in my 07 manual also. It cuts off at about 4500 in neutral

CalgaryTSX · 10-25-2009, 03:09 PM

My 2006, 6speed manual, has the 4500 rpm rev limiter when the car is not moving. But you can "bounce" it to 5000.

Approx 7100 rpm limit when the car is moving..

true story. in my integra, i had my ecu chipped to 2step at 4,500. its so that i can keep my foot on the gas and launch out without spinning the tires. BTW its not only for AT, MT has it too, and my rev limiter is at 4,500.
