E46 limiter

[TheRacingSnake]

I've had my E46 M3 (not on a public road I may add) indicating just over 160mph on the dial and 154mph on the gps. I thought these were limited o 155??? As far as I am aware the car hasn't been messed with in any way to remove the limiter.

I think all BMW M cars go beyond the said limiter.Never tried it in my E46 but seen an almost indicated 170mph in a mates E60 M5 and heard of many M owners exceeding 155 mpm.

The limiter is actually set to 258KPH in all gears apart from 5th. This equates to roughly 160MPH

It's pretty easy to remove the limiter

Mine is limited. Only starts hitting the limiter at this speed:



Need to be in 6th to get there.

The speedo is inaccurate by sound 5% to 10% and will therefore read high. I.e. up to around 170mh for a true 155mph speed..

Your car sounds spot on, if the cars are electronically limited to 155mph and your was reading 154mph on GPS then that is spot on.

For £30 you can get the car recoded to remove the electronic limiter which means the car should then reach just short of 180mph on your GPS device

My e36 EVO did 164mph at VMax right on the limiter in 5th. Ran out of room to see if it went faster than that in 6th (or slower).

Interesting re the GPS 180mph. Have you witnessed this? Mine was delimited from the factory, so hoping to test it out soon and see what it'll hit, but even with a little bit less weight, a few extra horses and the ram-effect I was thinking I'd be happy getting near 175

impressive. there is a vid of german chap doing 170, easy.

The limiter softly comes into play indicating about 170. The Satnav records v-max of 163 on mine when it was still limited.

Indicated off the clock worked out being 274km/h on GPS with my CSL on Cup tyres. Different tyres may have a different rolling radius, and thus speed.

So looks like 180MPH is possible in a delimited CSL then

You can do yourself with a copy of BMWFlash for $20. You can also do a few other tweaks like enable dyno mode, enable shift lights on a manual, rev limit change, CSL oil temp lights etc.

I put together an online web app so you can make the changes without having to edit the binary in hex

No. as I said 300km/h / 186mph on the dash is 274km/h which translates to 170mph.

that was on a delimited CSL.. it didn't have anything really more to give at the point I lifted off.

did that run many times, when I lived in holland, as it was part of my near weekly commute to the nürburgring (visited there 22 times in 2007).

People get excited because the speedo is over reading a lot - but its only really 10% out at 170mph, which isn't too bad.

Right, didn't realise that was delimited too, as thought there was more to give on the rev-counter in the vid. So it seems anything over 170mph GPS will be doing well then

Wow, that's great. Any luck with the Z4M MS S70 ecu?

Thanks.
