Speed Limiter

[R.Taylor]

Just discovered that my 19' is speed limited at 102mph.... Not like I need it any faster but they could have rounded it off at 105.... just sayin'.

And the cruise control won't go over 85.

Yeah. It is programmed governor that prevents you from exceeding a certain speed. They have been doing it for years for safety. Not sure why they chose that speed.

The speed is based off the tires speed rating.There are also legal max speeds in some foreign countries.I had to program a bunch of Promaster motor home conversions to 65 mph that were being exported

According to AlfaOBD my 2018 body control module really doesn't have a speed limit set.

Maximum Vehicle Speed: 255 km/h

255km/h is 155mph

The speed is based off the tires.

Mostly yes, but also brakes and drivetrain are a part that plays into this and safety concerns for the whole suspension and all related to it.
In European cars most of the time the engines power is the natural speed limiter, with the huge powerful engines in american cars they sometimes need to be limited because they are plain dangerous at really high speeds.

I ditched the speed limiter in my ol ZJ Grand Cherokee, was at 100mph, and all above really needed a good hand on the wheel to keep it on the road.
I just say German Autobahn..

...it made shy of 135mph then.

Loved the Smarty on my 06'... Set the limiter at 150mph but she'd top out at 122mph

My 11 HO DRW turning a SLOWWWW 2.300rpm's in 6th at 103mph. I think my 15 DRW is 104.
