S3 boost log, boost to high?

How much preload have you added? needs to be a couple of turns on a std actuator typically...

Requested boost does look high but depends on what mods you have and how it was tuned...

Preload on a std K04 with a std actuator is typically 3 turns from having the wastegate shut...

What you can try is to adjust the preload incrementally... undo the 'bottom' nut (the one actuator side of the wastgate arm) and back it off a bit... mark the top nut (the one on the end of the actuator rod) with a marker so you can see how far you have rotated it... tighten this nut one turn then tighten the bottom nut back up to lock in place...

Redo the logging you did above and compare... if its a preload issue you should see the actual start to move closer to the request...

Be careful though because if its been mapped like this then over doing the preload can result in a boost spike as the map is calibrated for a 'std' preload... too much and it won't be able to control the over shoot easily

Just had another look at your graph...

Spool isn't that bad in actual fact... I didn't pay too much attention to the RPM when I looked earlier...

You are getting full boost where I would think K04's normally kick in... Bill would be in a better place to comment as he sees these day in day out...

It could be that they have just lifted the load maps to get the boost up rather than just bring it in...

I will have to plead slightly ignorant here though as its been a while since I have had a K04 turbo or driven a car with one in... lol

Here is a dyno plot of a std S3 vs a hybrid K04 and my GT35...



Sorry, no boost plot for the std S3 but they typically come in a little sooner than hybrids so yours is in the ball park... maybe just running a little too much boost? don't know your mods but for that level you shou;ld have pretty much all of them to be able to justify that boost level
