350Z 2004 Rev limiting @ 3,500 RPM
PROBLEM:
Can't rev past 3,500 RPM on my Z, limiting ignition when not on gear (P or N, even when rolling). And when on any gear (D, +/-, or even Cruise) can't exceed 80mph.
The ignition cut is sharp! Exactly at 3,500, suggesting it's an electrical issue, and not mechanical/mixture etc... Even resembles an injection management control module.
Cruise Control works! Although the RPM limiter and 80mph max speed still applies (Which is a funny thing, making it relevant the the problem is not on pedal sensors) which also doesn't recall to low ECU voltage or anything else...

Yes
Figured out there were more maps.
Also nothing better than a good night of sleep
