Ok, Ive read a bit on the VVT functions, but have some questions.
First a couple of assumptions. Number 1 is that almost all the time (at sea level or there abouts) I will be running the high barro VVT table.
So my questions are.
1. Does VVT Timing adjustment B5154 apply across all 3 barro tables and is it scaled in any way based on VVT retard angle etc?
2. At part throttle around 2000 RPM give or take I get what feels like a surging/pulsating feeling. I thought this might be spark issues, plugs or leads etc. But it seems limited to this range. Which is pretty much the RPM where you get Max VVT timing and cam adjustments. So Im wondering if I am feeling the transitions across cells for timing and/or cam advance? Has anyone experienced this?
Next step, which probably should have been first step is to log everything :) And come back to add to this thread...
