I wouldn't worry about it too much, but would take them up for that offer as long as I had cash on me.

what you mean reset the vvti settings?

i dunno how to do it, but the computer that controls the VVT has some sort of intelligence (the i in VVTi) that tries to optimized the performance of your engine based on the way you normally drive.

So... something to do with the valve timings. Anyways, if the engine starts to knock.... the engine adjusts to not be as agressive... and thus loses a tiny bit of power to make up for the knocking.


i'm not an expert on this, nor would I ever claim to be... I just remember reading about this before the site got hacked.


hopefully somebody will chime in.
