Hey Guys,
Have a question here are bout the response time of the camshaft phasing units. Does anyone know how quick these things can adjust the cams? There is a pretty big lag when I drop down a gear or two (say, coming out of a corner pretty hard) and get onto the throttle at all when I'm driving. I'm trying to find the source of this lag to understand it and hopefully tune it out as much as possible. The obvious first answer here is turbo lag, but I don't think that's it. I don't think it is the turbo because the delay / lack of smoothness can be usually solved by releasing the throttle for a second and then getting back on it. Further, my boost gauge shows that there is boost but just no power. From what I can see in the data logs there is nothing funky going on with the spark or KR either, so I starting to get more and more suspicions of the electronic throttle delay or the cam phasing delay.
Maybe as a side note I had a email tune from a tuner a while ago, and the car exhibited the same problem. I started doing my own tuning to get more power, less KR, and in general a lot smoother ride. To do the tuning I followed all of the guides people have made (which are very well done!!) and really haven't done anything over the top. I've also tried and failed numerous times to track the cam advance in the datalogs but have failed. Seems like no matter what I do, as soon as I start recording the log, none of the custom inputs I've defined work anymore.
Any help / thoughts would be appreciated, thanks!
