does the mth write out the speed limiter or do we have to do something else

 

There is no speed limiter on the MINI.

 

Are you referring that the MTH tuning deletes the speed limiter? The speed limiter that comes on MCS's is 135 and JCW 140. IMO, that's more than enough for anyone in the USA.

I don't want to state the obvious, but unfortunately our MINI's are shaped like a brick and accelerating past 100mph, even with mods, takes a long time. The amount of drag is proportional to the square of the velocity; there are many other factors that affect drag (cross sectional area, front facial area, and more I don't know about), but anyway, I was trying to make the point that accelerating past 100mph is extremely slow and you need significantly more horsepower to get past 135.

 

By speed limiter I assume that he means somting that prevents the car from going any faster. If this is the case, there is nothing. Top speed is top speed based on what you mentiond (drag, HP and such). Top speed may be stated at 135 but I have had my 06 MCS faster (leagally on the autobahn here in Germany) so I can tell you that there is no limiter at all, simply the laws of physics.

MTH Tuner File tunes the car, adjusts the red-line and adjusts the DSC setting to make it less aggressive.

 

The reason your's has no limiter is because you're from Germany. Here in the US, our cars are limited to 135. You can feel it kick in, because the car is still accelerating and then suddenly it won't pull anymore.

In my opinion, the car pulls quite strongly after 100. Even when my car was stock, I was always amazed at how well it accelerated after 100.

But back to the original question...does MTH remove the limiter??

 

My Mini is a US Spec MCS and I am a US Citizen living here. This has been covered so many times in so many threads it is no longer funny. Why put a limiter on a car at 135 mph? There is no road anywhere in the US that has that speed limit. So, it makes absolutely no sense to even think there is a limiter. Bottom line, if you are doing 135 and you aren't on a track or legal road for doing so, you shouldn't be driving that speed anyway. I have hit 135 (legally) and there is no "drop" in speed as you describe, there is just little more left for the car to gain. My car crept up to around 140 but that was about it. If there is a limiter, please explain the reasoning for putting it at 135 mph? I'll be glad to bounce them off my neighbor who works for BMW and is used to servicing American Spec autos for service members. Urban legend my friend.

 

I do not believe that to be true. The car is a flying brick. It hits a stone wall because to over come the cd requires a lot more HP. JCW 210 is 142, not 140. Its all about the HP.

Although, on another thread, someone mentions an electronic limiter and elsewhere others refute it.

 

Just like all BMWs, Porsches, and Mercedes the Mini has a speed limiter. It is set at 135 MPH. MTH does adjust this setting with the Tuner File.

 

Guess my limiter is broken then because I hit 140 on the Autobahn. Still don't understand why a limiter would be put at 135, makes no sense at all.

Don, what does MTH move the limit to? Kinda curious now.

 

It's there because people like to push the limits (myself included). People need limits. The more mods you add to your car, the limiter is more noticeable, your car accelerates quicker to it and will still be pulling when it kicks in. Sure the mini isnt that aerodynamic, but how much of a difference could 134 and 135 make, to the point where the car is still pulling at 134, but not at 135? It's the limiter...not the aerodynamics.

But about cars not having a limiter...most German cars are limited to 155 under a agreement that all of the manufacturers have with each other. However, when the Audi S4 (B6) came out...many people found out that their S4's were definitely NOT limited. Some reported getting up to 170+. I would hope that the speedo could not be THAT inaccurate. It was decided that the B6 S4's aren't limited. Also, I've been upwards of 160+ in a friends E39 M5...a car that is also supposed to be limited to 155. ((This was all done legally of course...... ))

 

I find this hard to believe because my family has seen a few different sl500's and sel 500's and even and sel 600 of varying years that would easily do upwards of that. Never with me in the driver seat by my father fancies himself a retired racecar driver... well mainly because he is.

 

I'll yield to the fact that there is a limiter as I haven't got any proof otherwise (other than me getting to 140 in my MCS). Since I have only done this twice and don't normally go that fast, I can't say. My normal autobahn speed in unrestricted zones is 100 to 110 mph otherwise it is the speed limit.

 

I beg to differ.

Porsche is NOT party to that "gentlemen's agreement", which is really about tires. You can take it to the bank that if a Porsche says it can do 178, it can do 178 IN the US.

 

Yeah I don't believe Porsche is in it. It's mainly BMW, Mercedes, Audi.

 

The speed limiter on a Porsche is the rev limiter.

 

I'm have to say there is a speed limiter. for the US spec. Currently im on my second mini. After destroying my first one. My first was on 02. one of the first sold in the US (bought within 3 mins after the doors open on the premire of the MINI). It was the Demo car on the floor.. Had a build date of 10/01. With this car I was believing it was A euro spec or had the racing programming for the ecu. Reason behind this was the Rev limiter was set at 7600 and i buried the speedo on a closed course.(155+) This was in stock trim with exception of rims and tires. At the Drags could pull 14.7 in the 1/4 mile.
With my Current 03 build date of 11/02. The car is a true US spec. Rev limit is at 7200 top speed 135-140 depending on the tires. I have modded the engine alot including some of the first MTH programming That didn't alter the Speed Limiter. Currently in the mid 13's for the 1/4 mile and Dynoing over 200 at the wheels, But still unable to go over 140.

btw im not worried about going over the 140 mark cause its only once in a blue moon that i get to go on the closed course and run those speeds. I did the runs that did due to .. the 02 was a new toy and i just had to know.. the 03 cause it didnt feel as quick and to do comparison VS the 02.. and third time to check what the 03 could do after all the MODS.

 

Not to beat a dead horse... but i just don't understand this really. My fathers I've looked over at the speedo of my father's amg a few times and seen over 160. How could they be speed limited to 155?

Speedos are not accurate, especially in that range. Don't believe everything you read.

 

I'll let this one lie... but I will stir the pot one last time saying that my father was a pretty intense rally and road rally driver. And there have been many, many occasions where tsd rally computers have made it into each one of our family vehicles to read installed earth magnets off the rims. That being said, since i was usually the naviagator of said rally events and the time keeper for him... yeah I don't exactly trust anything but a rally computer and a stopwatch. I'm going to give him a call today and see if he had done any work to those cars, I do remember him comming home one day and spending all night ripping the abs system out of his alfa 164... because it "Can't stop the car worth a damn" I think were his exact words.



After talking with my dad he says the sl 500 was speed limited but he also said he was pretty certain that the sel 600 that he had and the e63 that he has aren't speed limited. He also said he would love to find out of the e63 was this weekend. Although tempting... I think my days of riding in a car that fast with a 60yr old are over. hah
