Hi
I can't found NMAX RPM limiter in my file. 168E4 in 16 bit not work. Limiter is about 5900-6000 rpm. Can you help me?

$168FA is a TNSC not a NMAXOG.
NMAXOG is at $1F824 - 8x1 map.

This is not entirely accurate.
The real picture is as follows.

$147BE   NMAXF   1x1   error detection level (nmax - exceeded)   
$168E4   NMAX   1x1   rpm limitation   
$1F7FC   NMAXDV   1x1   rpm limitation when vehicle speed signal error is detected   
$1F7FE   NMAXDVG   8x1   rpm limit for automatic transmission in the event of an error in the speed signal
$1F80E   NMAXDZ   1x1   rpm limit with double ignition output   
$1F810   NMAXGA   8x1   Maximum permissible engine speed (stationary)   
$1F820   NMAXKR   1x1   rpm limit for safety delayed adjustment of knock control   
$1F822   NMAXNL   1x1   engine speed limit when rpm sensor error   
$1F824   NMAXOG   8x1   Maximum permissible motor speed (short-term excess)   
$1F83E   NMAXTO   4x1   speed limitation at high oil temperature.
