Working, yes. What they were set to, another story.

It's certainly possible to re-map a speed limiter, and it's even possible to
do it by pulling a fuse but this will also disable the tachograph and other
electrics. It is not possible, AFAIK to disable a speed limiter with a
screwdriver and Blu-Tack but I am willing to stand corrected.

However, I think that "Depresion" is going to find an excuse to decline the
chance to explain the procedure.

Really? So what speed would you estimate that these three trucks were
travelling at as they overtook you?

My apologies, you're correct. I don't double man for that very reason.

About 69mph, which is faster than 56 mph. And on an uphill section
before you raise another canard.

Depresion seems to have recycled the tale about the tachograph's recorded
speed being kept artificially low by blocking the path of the speed trace
stylus, either with an elastic band, or a hard object held in place with
some adhesive.

Of course, even if this did happen- and I understand it is largely "urban
legend"- then this would not of course affect the speed limiter at all. In
any event, these supposed methods were only of any use before speed limiters
became mandatory.

When speed limiters were a bolt-on attachment they could usually be
overridden in some way, either by pulling a fuse, inserting shims into the
mechanism or, on Ivecos, by splitting a vacuum pipe.

Speed limitation on trucks is done through the ECU nowadays, and I don't
know anybody, including HGV fitters who would know how to disable one.

I just love the mental picture of "Depresion" walking down the road, minding
his own business when a gruff voice says " 'ere mate, if you've got ten
minutes to spare I'll show you how to disable a lorry speed limiter with
some Blu-Tack and tell you all about how I drive to southern Spain and back
in two days"
