ECU Reset... How?

As Partsman stated, this is really not an ECU reset at all. My understanding in all of this (having spoken to several tuners) is that the only way to really reset the ECU is to actually flash it.

Now, that being said, people "claim" that the car feels different after the dash reset but there is no proof and when I did it to my MINI I felt no difference. Maybe my butt is not sensitive enough. :p
 
Ummm the only correct way to do it is how I do it with my laptop and using the proper ECU development tools. Nothing else that I have found lets you reset so much e.g. all the adpations (Theres many of them). Well unless you go to BMW anyway and then they can do the same.

But like I said above that reset was taken from the FAQs a while back and it does seem different after it has been done. but maybe my butt dyno just went numb and I was getting different sensations. :D
Ok, I use the term "flash" lightly so let me clarify. I have MTH which uploads or flashes the ECU with new tables. Thus resetting them. However, you are correct, you have to have proper software to do this.

That one bit in the FAQ has always been a bit controversial and the folks that I have spoken to at MTH and at others say that the reset mentioned does nothing for the ECU.

That being said many argue it and claim that it does work (didn't for me). Personally I don't think that it does anything for the ECU (maybe the BC1) but without a MINI technical background it is hard to fully grasp.
