My idle is pretty flat and smooth, so any comparison might not be correct. Like I have zero direct injector duty at idle, but you have a combination of both, but is that because you have a fluctuating idle or is it just a difference in tuner and is it bad or is it fine?
My throttle angle at idle says 14.5 and your sales 0, so I don't know if my tuner had set up the idle to be higher than stock. My port time at 900-1500 is 1.0-1.25 ms and my direct is 0. Your port time at 1500 is 1.25 to 1.35 ms, and your direct time is 1.65 to 1.85 ms, which means you have more fuel going. Your afr is not hitting close to the target, fluctuating up and down, but I don't know what is causing that situation. My vacuum at idle around 900 rpms is 0.32 bar, which is 0.68 away from 1 bar of atmosphere, which is 20 inHG of vacuum. Your 900-1000 rpm idle was fluctuating around 4.5-5.5 psi, which is around 18-20 inHG, so I don't think you have a leak in the manifold, or I feel like that value would be much closer to atmosphere.
What does your tuner say?
