I need some help here fellas.

I purchased a 2003 Sequoia 4X4 and just found out about the rev limiter when in 4WD. I was heading up a muddy slope and was unable to get into the power right near the top, the engine wouldn’t rev above 3K rpm’s.

Now I have read that if I’m in low range in drive 1 it counter acts this but sometimes I would like a little more power when in the loose stuff (mud and snow). Is there any way to override this? Am I able to flash my ECU, pull a fuse, or snip a wire? Did I just buy a soccer mom taxi?

Appreciate any insight or explanation anyone can extend.

Thank you!

for the most part i would say unless u have the ecu reprogrammed more than likely u can not over ride it, now if u can get a hold of the wiring for it and look it over and see if it shows a speed sensor or rpm sensor wire for the 4wd portion of the Sequoia and doesn't also feed any other system then u can snip it and try. well i would disconnect but you get what mean.

I think your confusing the vehicle traction control with a rev limiter. Ive done some silly things with my sequoia in 4wd and have never once encountered a rev limiter. But I have encountered traction control. When it senses excessive wheel spin the motor is held back regardless of your throttle position. You can somewhat disable it when in 4wd by pressing the vsc off button.
