Hey Vigge, I notice we're running out of room over there. When you figure out a way to discredit the graphs I've posted, why don't you respond over here so I can see it more easily. Thanks.

Oh, and, all of those runs you're quoting? You do know they don't mean anything to the argument right?
----------

You wanted a comment based on that file so you'll get it, but like I said I dont want to jump into conclusions if I dont know for sure that this is "normal" behaviour for your car.

Lets assume that the A/F curve is the same in fourth and fifth gear, as in that first file you provided. How long do you think the acceleration will take in fifth from 2000-4500rpm?
We know it takes several seconds, right?
Your A/F showes 14.5 all the way from 2000-45000, so what do you think the thermal stress, EGT will look like, you pass max boost and torque with an A/F of 14.5? And you dont see a problem with that?

Do you see know why I quoted the location of your sensor and stated that thw sweep is too fast and may lead to wrong interpertaions? If your sensor is down the line, there will be delay. RPM will also pick up too fast before the controller has time to react, ie add fuel.

Secondly that A/F would be just fine for a turbo engine, that has a bigger turbo that does pick up from 4000, but this is not the case with TD04-15T or is it?. My files show that at 2000 rpms the turbo can provide 1 bar of boost...

But like you said there is no point in this conversation what so ever, well I feel alike.

Ps. this above only aplies, if your A/F in fifth does look the same...

Have a good day in Huston.
