VVT Advance
Has anybody compared the values of the VVT Advance angle right with the
VVT Advance angle left, on an STi 7 type RA? The ECU code is af480-7541.
On my logs i can find the right advance to be always about 3 degrees more in comparison with the left advance, and on high RPM the difference is about 1-2 degrees.
Is this normal for those special cars, or it's an OCV problem?

You shouldnt find any difference in the new age STi engine between models (ie the GL/EL and Spec C type RA).
You really need to speak to Bob Rawle or the likes, so if you do a search and email him you should get an answer back

It should always be the same for both banks, if not then there is a control or feedback problem somewhere, there is only one vvt map for both. So either the position sensor or the actuali servo could be at fault. Quote some values and I'll tell you which is wrong, need rpm, engine load and angle points.
