Just to clarify, the 92 and 93 ECUs have a limiter too, but that limit is 155 MPH, not 127-133 MPH. You can live with 155 MPH, correct?
Correct on the model years for the limiter set speed. However IIRC on the 034 the limit is a mere 149MPH.
If anybody here did not know and ever wondered, the 130 mph (actually 210km per hour) on most of the USA versiom vehicles starting in model year '94 was done so that the cars could be factory fitted with the much longer wearing, lower speed rated, all season tires so loved by Americans.
Remember this is the era where things were just starting to be driven by JD power consumerism, something that people imagine to be fabulous, but that I find to be destructive in the long term. On one hand, it does prompt responsiveness towards the customer. On the other hand it results in the wholesale "lowest common denominator" dumbing down of interesting and / or iconic products.
A great example is this USA speed limiter thing. In my deeper emotional center, I absolutely abhor this. My more intellectual and practical mind wished for this out loud, as did those of everybody else involved in the sale and servicing of these cars.
Believe me when I tell you that you absolutely can not even slightly imagine the customer dissatisfaction and relationship issues that got to be commonplace as these cars were routinely fitted with lower profile and V, W, Z rated tires. Unless you were there, you don't have the slightest idea. Our 300SE customer really wasn't trying to hear that his 8500 mile and six month old car needed new tires because it was designed to safely cruise a damp Autobahn at 220kph. It might've been
my favorite thing about this gigantic paragon, but it was
not his!
You know what, none of these customers are trying to hear that today either, ironically least of all the AMG customer with the cord showing on the center of the rear tires, and the shoulders of the front tires at 3800 miles, especially since, as he reports he is just the gentlest of drivers. There are a bout a bazillion of these occurrences. You get to see this on the Internet with the opening line "You won't believe what those idiots at the stealership told me today!"
