Default More on my DBW issues...

1. You DBW guys have it teh suck.

2. Under high boost, the car pulls the throttle back as low as 20%.

3. I know not why it was boosting that high. I pulled the PCM, as I was going to talk to thechip manufacturer, and guess what? No chip. I suppose it could be flashed ( I dunno much 'bout DBW )

4. The wastegate looked fiddled with. I backed the adjustment off about one turn and then drove the car.

At this point I had no boost, as in zero. As I drove it started making more and more boost, up to 7 psi, but it seemed to come on very late and not very hard.

How can I tell if it has been flashed, and why would it restart with no boost and then start to make boost?

And how, exactly, should a wastegate be adjusted on a K03?

Default TC happens when actual boost exceeds requested boost by too much.

if the wastegate was fiddled with, this could happen at low rpms, or anywhere on the boost curve. what turbo is it? a ko3? i have a good resolution pic of the wastegate settings, you could count the threads and set yours to that.<ul><li><a href="http://www.modifieda4.com/gallery/k03-turbo/DSC00481?full=1">link for high res, k03 wastegate rod pic.</a></li></ul>

Default Requested boost is above actual

and a pic would be great. Is it odd that after pulling the PCM I went from 20 psi to 0 and then as I drove it worked back up?

Default not odd, when you pull the ECU you reset it...

Default depends on the program..."no boost" is wierd...but stock boost wouldnt be...

my wett ko3 chip tended to take a day to start making any real boost, the giac chip seems to make more sooner.
