Anyone have experience of DMS Automotive?
Discussion
Have to say I asked DMS about remapping my e46 325 - really refreshingly honest reply "We do not offer an upgrade for your vehicle as we have failed to obtain what we would regard has viable increases in performance. Expect to see around 10-12 BHP and 8-9 lb/ft torque. Whilst the throttle response is improved there are no real discernable gains in overall performance."
Interesting though as morego (AKA BBR in brackley) are quoting me an extra 22hp and 30nm of torque for £350 cant understand why there is such a difference???

Maybe because it's not true? I wonder how many people bother checking their claims via dyno? I'm certainly going to stick my chipped 535d on next time my caterham being mapped.400Nm said:
Why is DMS so highly reguarded as being the best?
Have a think before you get your wallets out.

I might be a bit hard of thinking here,
but if these remap chappies are so good, why
don't BMW offer the same service themselves ?
Is it a question of the same software running worldwide
or so the car is tuned to work on manky 91 Oktane petrol
or is is just a question of reduced engine longevity?
Enquiring minds want to know.

Risk management. All engineering is about finding an acceptable solution to a problem.
Problem: Engine to run well, behave in traffic, produce ample power, less than 1 failure per 100,000 engines
Solution: Factory map
Someone like DMS etc dont have to worry about the last part so much, so 1 failure per 10,000 would be acceptable but would allow more power as they are closer to the edge of the envelope.
Arbitrary numbers but you get the point.
Also the yucky stuff your car chucks out has to be limited.
Factually, their is very little difference between a UK or US M5 (except US ones have nasty power sapping carbon filters), however BMW as with other car manufacturers can't make different power outputs for each market/country, so they go for the lowest common factor & then supply on that basis. So all M5's are EU4 compliant & in California they had to go further & fit these carbon filters.
That said all manufacturers have to limit outputs to make their cars compliant around the globe. As you know, in the UK many manufacturers signed up to this silly 155MPH top speed limit but car makers don't limit every car to this, they just apply code to UK bound cars that provides the limit. You'll see now how most of what makes cars perform is now code based & therefore by altering the code which then adjusts the juicy bits, you end up with a quicker car.
That said it may well have an impact on the cars lifespan, but a 7% increase in power on an M5 is hardly likely to cause a major failure. This is why i chose DMS to tinker with my car, as i trust them 100%.

Not quite.
I think you will find that a 155 mph limit doesn't make
a lot of difference in a 70 mph country.
It is more accurate to say that a voluntary limit is applied
by some, not all, manufacturers to keep the German
Green party happy.
That voluntary limit is applied across Europe.
