Reving on Neutral

iskandef · 08-23-2010, 08:42 PM

So my friend asked me to rev my car so he can hear the exhaust. My car was on neutral when I rev'd and wouldnt let me rev past the 5th rpm. Is this how the car naturally is? If so is ther any way to get rid of that

It's limited by the ECU to protect the engine. You can remove the rev limiter by re-flashing ECU with the aftermarket one.

If you put the car in gear and hold the clutch you can rev higher, but you shouldn't rev an unloaded engine that high. That's why the limiter is there... to prevent you from breaking everything.

heh I remember this scaring me before I realized what it was - I thought my car was in limp mode already or something! :P

Yep the clutch-in, first gear works - just remember that even when it's not connected to anything the engine is still generating torque - and enough torque can strain the mountings and twist the whole shebang up. Torque is better off sent to the wheels!
