Thread: Can ECU remap be detected ?

BUT don't the dealers update the map when they service the car, and therefore you lose your map?
Regards Philip A

Yes, I believe the remap is lost with a software update but I was told that the dealer only performs a software update if they have a major problem with the vehicle.






In the event of a software upgrade the supplier gives you two reinstalls of the remap.
Does anyone know if dealers do a software update as part of a regular service routine ? Or just wait until a new software version comes out from UK ?

*No the dealers or anyone using the SDD diagnostic cant see a "remap"
*Some remaps though show a checksum fault, which gives me personally an idea its had a remap.
*I believe there is some additional software available that can detect a remap, but the dealers dont have it.
*A standard scheduled service doesnt even include an air filter, what chance do you think a software update is done.
*As previously mentioned, software updates are only done when there is an issue with something.

Thanks Dazza - that's what I thought and basically told by remap supplier.


Now just to weigh up the pros and cons of getting a remap on a new vehicle ( and the whole warranty issue ). I don't want sports car performance from a DTV6 - just extra torque and ease of driving would be nice.

If you go with a BAS RRC (Remap Remote Control), your remap file/s and the original map are stored on the Bluetooth device that plugs in to the OBD port so can reload your own remaps. So with this you can reinstall the original tuning map for dealer visits.
But, as Dazza says, there's probably no need.

Thanks Beery.
Do you have a BAS remap ? f so, is it good ? Are you happy with it ? What engine performance to you notice the most ? extra torque, low, medium or high revs ? Any feedback appreciated.
My wife has a BMW X3 3.0lt with 590nm and it flys in such a small body. You can accelerate quite quickly with relatively low revs.

BAS don't offer a remap for the 3.0 yet due to the 3.0 up until very recently needing to be cracked open and physically connecting to the PCB (which definitely makes it obvious you have had a remap)
I have heard word that there may be some suppliers offering OBD port remaps for the 3.0 very soon though.

Can they find it? Yes - AS stated LR can upload the current file to the UK and compare the file.

Do they do this often? No.

Depending how yours is done the ECU will be opened. Again this is highly visible to LR.

BAS RRC2 isn't yet capable of the 3.0 but I doubt it will be long.
