Why Did My Z, Keep Revving? Video.

?? This is probably a matter of semantics here, but mine will not rev until the gate sensor is triggered. This is never too late for a matched engagement. Maybe you're shifting at the speed of light...I dunno. Wiggling your stick around in neutral should not trigger a REV as a few have reported and as was ultimately found to be a fault in the OP's car..

Maybe you need to do the Neutral Learning procedure?

3.PERFORM M/T NEUTRAL POSITION LEARNING
Without CONSULT-III
NOTE:
• It is better to count the time accurately with a clock.
• It is impossible to switch the learning mode when a clutch interlock switch circuit has a malfunction.
1. Check that there is no sticking when shifting shift lever to the neutral position.
2. Turn ignition switch ON and wait 5 seconds.
3. Within 5 seconds repeat the following operation 3 times. Fully depress and fully release clutch pedal while
pressing and holding S-MODE switch.
4. Wait 3 seconds while S-MODE switch is released.
5. Wait 5 seconds while pressing S-MODE switch.
6. Wait 3 seconds while S-MODE switch is released.
7. Within 5 seconds repeat the following operation 5 times. Fully depress and fully release clutch pedal while
pressing and holding S-MODE switch.
ECM starts M/T Neutral Position Learning.
NOTE:
Never touch shift lever. Otherwise learning may not complete normally
