Default Re: Comprehensive MSS54/MSS54HP DME Information

Deregulation of speed limits on MSS54HP:
At 0x8F94, you'll find the gear maps:
Code:
00 00 00 01 00 02 00 03 00 04 00 05 00 06 00 07
And at 0x8FA4, you'll find the velocity in kmph * 16:
Code:
10 20 10 20 10 20 10 20 10 20 0F E0 10 20 10 20
Translated:
00 00 = Reverse
00 01 = Neutral
00 02 = First Gear
00 03 = Second Gear
00 04 = Third Gear
00 05 = Fourth Gear
00 06 = Fifth Gear
00 07 = Sixth Gear

Divide by 16
10 20 = dec 4128 / 16 = 258 kmph in reverse
10 20 = dec 4128 / 16 = 258 kmph in neutral
10 20 = dec 4128 / 16 = 258 kmph in first gear
10 20 = dec 4128 / 16 = 258 kmph in second gear
10 20 = dec 4128 / 16 = 258 kmph in third gear
0F E0 = dec 4064 / 16 = 254 kmph in fourth gear
10 20 = dec 4128 / 16 = 258 kmph in fifth gear
10 20 = dec 4128 / 16 = 258 kmph in sixth gear

A CSL deregulated file seems to show speeds of 11 D0 (dec 4560 / 16 = 285 kmph)
Code:
00 00 | 00 01 | 00 02 | 00 03 | 00 04 | 00 05 | 00 06 | 00 07
11 D0 | 11 D0 | 11 D0 | 11 D0 | 11 D0 | 11 D0 | 11 D0 | 11 D0
Changing the values from 0x8FA4 to a reasonable number like 15 22 should push the regulator up to 210 mph (338 kmph).
