I see a bunch of theoretical arguments. However I would like to know how you can argue dyno results etc? I have been witness to a certain circumstance in which an individual purchased your OBDII program and witnessed a decent and immediate increase on the dyno. After several weeks the power increase had dropped considerably.
Now, a few instances in which the power has decreased can be explained away as probability or varied conditions etc.
But, If these conditions provide variations in measured HP then there would be positive and negative variance by similar % in the dyno results.
I have never heard of such a result. Have you?
We can not assume that this "power loss" is a regular and certain phenomenon b/c we do not have a representative test group of the BMW population. However we can suggest a correlation or trend such that OBDII cars lessen in RWHP weeks after flashing OBDII.
