Hi,

Just picked up an F15 X5 25d 2015.
Car came with a 2 yr BMW warranty.
I would like to remap to improve BHP and also economy.

Is a remap visible to BMW?

Cheers
David

short version all remaps are visable regardless of what tuners may say depends if the dealer checks but these days most dealers check first thing for remap evidence with engine warranty work......

Yes and it will almost certainly invalidate your warranty.
BMW probably offer a performance upgrade if you want to go down that path.

May other tuners will say it’s not detectable

And it all depends on which way they mean

If a bmw tech drives the car and looks at the live readings then he will see it’s been tuned

Some tuners turn the tuning protection codes off or set the programming data as it was before it was touched so the diagnostics with not flag it’s been tuned but the if the tech does the above he will see it is

We are honest if your worried about warranty then wait till it’s run out before remapping it


There are so many dishonest tuners out there as I’ve found out from the work they have dose to customers car who came in for me to fix them

Tuning Box is the only way for warranty issues.
I use VenturaTuning powerbox and is a 2018 F30 330e, now with 314Hp.

Each time I have a service I remove it and install again. When removed goes back to OM Settings, so no trace.
It’s Plug&Play , 4 connectors and easy.Or gosto a car shop, 5 minutes.
It will get 275Hp or 260Hp depends if is the xdrive or not.

Modern day ECUs keep logs even if a diesel box has been fitted if you look deep enough

Also tuning boxes don’t make the power they claim


If you really need to tune your car it’s best to remap it then before you take the car in to a dealers put the ecu back to standard

For me the best tuning boxes are Ventura and AC Schnitzer.
the majority of fóruns they only talk about remapping and never talk about a lot of problems that can happen doing that

If a car is Remaped correctly by a good tuner who knows what they are doing then there will be no problems


Now what about all the problems boxes cause and the fact they don’t make the power they say

As well and not showing the before dyno readings only claimed power output
