Hi would be great if some1 could help. I had my BMW E90 remapped today and was told to give it a week or 2 to learn the map and get it's full potential is this true?
That’s balls... Was it an ‘e map’ or was it done at a proper remapping business with a rolling road?A maps just that, it’s there, in the ECU and ready to go there & then...
This is actually true, in part.
The map, will be more aggressive, it will give you more power etc from the off, and so it should.
The e90, same as others, has things called "adaptations". What this does, is try and compensate from wear, and issues that you car has, through tiny inlets of air where it shouldn't, fuel and injector issues, issues with temp readouts, voltage on lambda sensors and not sensors if fitted.
They take time to monitor, and auto adjust, same as the gearbox does if someone resets the gearbox for the auto cars (I am told you shouldn't as can cause issues with re learning the wear on the mechatronics.
To you, it means not a lot, the car should be faster already, but it will bed down over a couple of runs.
You can read adaptions in ISTA, if they are extreme, it actually points to issues with the car, even with no fault codes, a good tuner will have checked out the car before to know what they are working with.

Thank you for this info I did have my gear box reset about a week ago because I got a rock stuck under my car and smashed my gearbox sump so had to do a new oli change it was changing gear to 3rd at about 3000 revs so I had it reset it dose feel abit faster after the map but wasn't sure if giving it a week or so was true it's a 330d with 80k I will just get a rolling road after 2 weeks 👍The map, will be more aggressive, it will give you more power etc from the off, and so it should.
