Hi Ludis,

> $00C8: rpm (0..224..255 == 0..5600..7150rpm)

This would imply:

RPM = 0x00C8 * 28 (rather than 25).

The problem I see is that RPM for ALDL table and 00C8 are used and swapped
in various places.  00C8 is updated with the RPM 0063.

NTRPMX       ENGINE SPEED (RPM)
RPM = N*25

0x19 (25d) is used for the NV_RATIO .

Of course the ALDL listing could be wrong of course, but .....

Or maybe C00C8 is offset somewhere.

So I don't see the rev limiter working out to 255 = 7150 RPM. (28.3...)

What am I missing?

.
