Top Speed Limit Help

[Duramax 6.6L]

I have altered the top speed limiter and for some reason it is still only able to go 98 mph.

Table

H0106 Vehicle Speed limiter Option: Disabled
H0105 Vehicle Speed Limit Upper: 153
H0110 Vehicle Speed Limit To GMLAN: 157.7
H0109 Vehicle Speed Limit Lower: 152.9
H0108 Vehicle Speed Limit In 4WDLO: 62.8

Any ideas on this would be greatl appreciated.

Reguards,

Not to insult intelligence, but are you looking at MPH and not KPH? 157KPH = 98 MPH.

Yes I am looking at MPH, That is what is so weird, That is he first thing I checked.


With the speed limiter totally disabled, I would think that the speed setting would not apply.

You would think that disabling it would have that effect.

I have mine set to 'enable' with 150 MPH as the top speed. I know there are some tables we can't see and by disabling the limiter here, the computer may fall back on another "hidden" table.

With mine set like this, I EASILY blow past 110 (off road of course ).

If that doesn't work, check all your torque limiting and RPM limiting tables. The possibility is remote that you are being limited in one of those, but you never know.
