Good luck Bokke, but don't expect to be able to detect the filter removal. There are so many variables that can affect performance that, to have a chance of detecting something like filter removal, you'd have to have your techniques down and long histories both pre and post, for example, filter removal.

Yeah, performance differences may be hard to capture but I was thinking that they GT2 can capture any horsepower gains? I mean, if all the settings are kept constant, would the system show a possible increase in HP?

I don't really see how. Everything that is disclosed by the meters starts with g-force. So, if a run is good (bad), then you would expect high (low) HP.

Okay, I think I get you. I had thought that the hp calculations were independent of how good a run was but I do remember seeing different hp numbers in your data which varied with each run.

My Escort GT1 should arrive today.

It's snowing today ... and may snow on and off for a few days so I don't know when I can get some test runs in.

That is super--to have you and a 550i joining in. I didn't realize that you are interested. Good luck.

I did my first two post-dealer-trip runs this moning. One, which I am not reporting, was a "disaster" with DSC/DTC both on. No way Jose in my car, but things apparently are different for grogan545. Today's "good" run wasn't really that good, but, hopefully, the "problem," vis-a -vis my last two attempts prior to my dealer's reset, is that my car is starting its learning over again.

HP readings not good. And, leaving the line was not good--despite having no wheel spin. I had one aborted run when my Step pulled its cute trick of shifting way early after I encountered only modest wheel spin.

And, my best 0 to sixty now is 5.43.

Great to have you join us "testers".Looking forward to seeing your times.I realize with the weather in chicago it may be a while before you can do meaningful testing.

grogan545

Hopefully it's just that your car is a "slow" learner.It appeared that your times were improving right before you went back to the dealer.
I also am amazed that I was able to get good times with DTC/DTS engaged.I don't know if this will continue but it is the only way I can get moving without massive wheelspin.I intend to go back to doing things manually when the weather warms up.My earlier experiences with the controls engaged were also a disaster.I abandoned this method after only a few tries.I cannot explain my sucess now with controls on but I will continue to test in this manner for now.

PS. If I duplicate my pm info to you Znod this will remain my method of choice.

Maybe 20 broke your DSC/DTC. I wish it had broken mine. I hate the idea that if I start with about the right amount of wheel spin, then the Step is likely to shift way early--producing a dead spot. The effect, at that point, is like having DSC/DTC on off the line. Ugh! I think your car needs new tires. And, I hope my car is just a slow learner. I understand about the PM.
