Thanks.

Just starting to run my engine in and the AFR is 15.5 @ idle and going upto 16+ on light/part throttle.
I have just replaced the PF09 TPS with a PF01, as i have L6 ecu and std loom.
Set the idle speed and now going to adjust the CO screw to bring AFR (using it as a CO marker) at idle down to 14.
Then test again.

Would this seem a reasonable logic to follow ?

I need the car running reasonably well so i can get a few hundred miles running in done, then bring in for a full setup and map.
