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.
