1zz engine in 06 vibe

Post by oldgizer »

How can I increase the rpm"s above 6300? Is there an attachment to overide the ecu?

You would have to change out a couple chrystals inside your ECU. It will completely remove your rpm limiter. Not recommended!! People who have done it have blown their engines due to revving too high.

At 6300 rpm you've gone past max torque and horsepower so why go even farther past them?

Also, you'll be running the risk of floating a valve at those high rpms. If your getting 'bigger' cams I can see raising the rpms a little. But on a stock 'ish' engine I agree that it wont do you any good. The easiest way to raise the rpm limiter is to go with a stand alone ecu.
