2020 HD speed limiter

[Brutal_HO]

Has anyone been able to effect a change on the speed limiter with AlphaOBD?

Seems no matter what I set the option to, it doesn't do anything and tops out at 101.

I realize the (current) tires are not rated that high so please, no safety lecture. I just don't want to be artificially limited if the need ever arises.

Is it possible it’s subject to the emissions parameters now?

I've tried to adjust both max speed as well as cruise speed limit. neither worked.

What’s the cruise speed limit?

 

[elephantrider]

85.

Nope, I had the cruise set 89 part of the way yesterday and it was working fine

you know it may be closer to 90. I'll be on the toll roads later this week, will confirm what my truck is limited at.

You can bump up the cruise after it's set at a lower speed, but I think it's limited on the initial set.

I seem to recall a member getting their new truck and it ran up well over 120 with no apparent limit except RPM's?

I've seen that exact thing on other cars. You can only set the cruise up to a certain max speed but could bump it up with set+.

@1FastHemi

Did you get the speed limiter removed from your truck?

I haven't been back in to get the mods or changes made to the computer yet. I worked it out with the dealer to get it all done at the first oil change.
