RPM

  Hi,
  
  a car's rpm meter can go up to at least 5k rpm.
  
  is there a way to control this rpm from going higher despite pressing down the gas pedal further?
  
  regards

  Get a rev limiter or redline without changing gear

  stock ecu's have a rev limitor built in. so matter how much u press the accelerator, the ecu will cut fuel automatically after redline to prevent the rpm from going any higher. dun believe can try.

  my fren car rpm can shoot to quite high but after that despite continued pressing the gas peddle, the rpm drops to around 2 k rpm lower and hovers there and then difficult to reach the high again. its auto car. is there some kind of computer control in the works?
  
  could anyone advise as to the Y?

  tailslide already gave the answer mah. The whole idea is to prevent the engine from over-reving and damaging the internals of the engine block. Doesn't matter if its an auto or manual car. It's all controlled by the car's ECU.
  
  For some cars, if the ECU detects a malfunction within the engine system itself, it can limit the RPM to for example, 3000rpm. A warning light will appear, usually indicating that the engine has got some malfunction and requires immediate attention... which means get it to the service workshop asap.
