Whilst this is quite exciting, can you imagine how BMW will react should you have a problem with the car and they find out it's mapped!

It's quick enough as it is let alone another gazzilion BHP & torques.....

The marketing words and price make me think it's DMS.

2 things:

1) undetectable - how?? A simple boost pressure reading would show it's been tinkered with.

2) remapping a leased car - implications??

That was my guess as well yes

Leased car - you'd be bonkers IMO.

Tread carefully, BMW know who you are and monitor this forum!

On a previous Seat forum someone with a modded PCP'd Cupra had Seat UK come down on him.

But 680bhp! Wowsers!

But still less than the new 707bhp Dodge Charger saloon - what will that get tuned to- 850bhp? Mental!

But agree with HoHoHo below 560 almost enough, but only because even in MDM mode the power is cut so often that more power would be intensely frustrating without wider rear tyres - an argument for a Hamann wide arch kit? wink

That would be a concern for me too, BMW poking around various forums and it probably happens yes

As it is, believe me 560hp is pretty bloody good out of the box yes

I don't know we have bought BMW dealer cars which have had modifications... One in particular was an E39 M5 which had Haywood Scott back box and had almost certainly been re mapped and delimited by the way it drove! Although not sure how it would work on a leased car?

My take on how this may be 'undetectable'........

It depends how the tune is applied. Take my A45 AMG for example. Eurocharged and Rebellion tell me it is 100% undetectable because:

The tune comes via a piggyback ECU which diverts signals around the major sensors.

The boost pressure / manifold pressure sensor is unplugged from the oem ecu loom and the piggyback loom is plugged in. The oem plug goes into the piggyback.

The throttle positon sensor is as above.

As are a few other sensors. It's a 15 minute job to unplug and replug.

Come service / dealer visit time the piggyback ecu is unplugged (not the loom) and a bypass plug installed in its place to re-route the oem sensors, which are still integrated into the new loom, back through the oem ecu. The oem ecu / cars brain has no record of the piggyback as the data was never absorbed by the ecu. The piggyback loom is hidden away under the engine cover and is only visible if you look for it. When the car comes to sale or return to the dealer you just do the reverse of the install and the car is back to 100% stock with no trace of tuning.

Thats how it works with the Eurocharged ituning packages. OEM ECU's were sent to AMG to see if they could find traces of the tune, and they couldnt!



Edited to add list of sensors diverted; MAP sensor, Throttle body switch, Boost pressure sensor, Camshaft sensor.

That is not a remap but a tuning box/piggyback solution.

The OP quotes a "remap" which implies the original maps are overwritten.

So my question remains unanswered...

The latest ECU's are very clever , I would leave well alone.

Its not just the ECU, its the dealer equipment. As soon as it is connected there is a chance it will see the flash counter and will know something is up.

Remapping a lease car sounds mental to me. I also thought you couldnt take lease cars on track days, but I am sure I saw pics of the OP's car on a track day?

The latest cars "talk to germany" they have for 2 + years, I will have more than enough power for the UK, I have ordered the M6 GC CP which for me will be more than I can really use here.

Wasn't meant to be abrupt just factual - if it read that way sorry.

I must be more careful for the sensitive types...

Providing you can why not?

Would be interesting to have the official line from BMW re their view on the official warranty and on-going for the next owner.

I think its mental not from a cost pov, but what happens if BMW decide that when something goes wrong, they detect the map and refuse to fix it under the lease / warranty terms?

And re tracking it, that's good as I've read on here before of people saying that lease cars can't be driven on track days because of the agreement.
