When I floor my zx3 (2002, ATX) it reaches over 6500 rpm consistently even in highway driving. I thought the rev limiter was supposed to keep it below 5000. Did Ford not put the rev limiter in all ECUs? Or am I wrong and the rev limiter kicks in at 6500 (in which case, why would anyone really need a chip unles running turbo?). Or is my rev limiter "broken" (not that I am complaining). I have no chip, no ecu mods at all (yet!). What do you think?

i believe the stock rev limiter is set to 6850. or something near there...

Yeh, it's 6850 on MTX cars, dunno about ATX.

It's 6,500 on all ATX's. We get screwed. Also, since you have a 2002 you get screwed with a different throttle body too. 03' has and even newer TB that is crazy different.
