      just back from a drive on the highway. But I was just letting everything get good and hot. I'm NOT running any boost right now. I've adjusted the wastegate to always stay open. I'll go thru all the exhaust bolts tomorrow to make sure they're tight. Drove like stock as expected, but I did hear the diverter valve open .
      wastegate adjusted open:

      Nice work Rey!!!! I can't wait to see the results of this...
      If you still have the car under control, you are not going fast enough...

      Horsepower is how fast you hit the wall, Torque is how far you take the wall with you...

      Good stuff. [IMG]http://**********************/smile/emthup.gif[/IMG]
      Suggest: hook up a temporary (or permanent) boost gauge so you actually
      KNOW where the boost is going.
      The ~partly open wastegate valve will not completely keep you out of boost.

      Funny how launch control and NLS were gimmicks when Matt bought it to med9.
      Now others are using it to make people think the sun shines out of their 4$$.

      thanks Jeff. I've had a vac/boost guage in for a while now. I wanted to see the difference in mani pressure behavior before and after. The needle stayed in the 0 psi box, just on the boost side edge compared to middle of box like before the install.

      The motor doesn't 'suck' anymore.

      Well, it still only has 8 valves. So, I wouldn't say that's entirely true.

      i just wanna let it be known...i have a stock wrx turbo on my AZG with...its slightly larger than the k03

      i hit 10psi by 2400rpms and 15 by 26-2700... i think that it's ridiculously torquey and LOVE EVERY MINUTE OF IT...i can not imagine how much faster the damn k03 is gonna spool...i'm gonna go head and guess 10psi by like 2k!
      also i'm running 8.5:1 compression....

      looks a little more than 'slightly' to me. How os it on the top end? (highway)
      What psi do you run, or plan to run to merit the compression drop?

      Logs: (how to use -> first scroll down to be able to scroll across. Find a spot then scroll up to compare)
      0 boost
      4psi boost
      even with only 4psi, I'm running lean. I wouldn't have thought that. You can see the increased MAF readings.

      jus so you know..those two links are the SAME
      as far as my setup...i currently run 20~21psi and she holds it jus fine. The last log i did was at 18psi and she was showing 19.5 degrees total timing up top i LOVE drivin this car!

      yes. but duty never goes above 70%
      tho injection time does platue @ 16.32ms... what's that about?

      i wanna know where you're gettin your injector duty cycle from? how are you calculating it or what vag block is it? also do you have AIM..this will be quicker to discuss on there?

      all these logs are from blocks 2 and 3. Injection duty is calculated from rpm and inj. time. (inj time (ms) / (120000/RPM)) * 100

      hmm good to know...well here's the issue...the ecu is still able to compensate for the air flow coming in and keep it around the specified/requested a/f....best bet is to either A: get c2 software with 30# injectors B: do the dreaded rising-rate fpr C: get lemmiwinks or unisettings or custom settings and add fueling under increasing load. or D: get 30# injectors as thats what 1.8t essentially have

      Seem as though k03s @ 4psi is good for a ~18% increase in air flow.

      yea the ecu is able to compesate somewhere in the realm of 25%

      here's the snap shot of A/F before and after:
      0 boost on left 4psi on right

      Just put in a 4bar fpr and will do some logs tonight.

      Be VERY careful.
      This 16.32ms 'cap' is a ecu data block limitation.
      i.e. the data the ecu sends to vag-com can NOT go above this value.
      I'd bet a few dollars you're running more inj. duty than you believe.
      This ecu DOES NOT have wideband fuel control...
      there is NO live fuel trimming under Full load here.
      Be VERY careful.

      Funny how launch control and NLS were gimmicks when Matt bought it to med9.
      Now others are using it to make people think the sun shines out of their 4$$.
