Hello everyone, im getting some wierd timing pulls on my n54 6mt on mhd v10 stage 2+ on e30. I have all the supporting mods required plus some. Specifically 2nd gear likes to pull timing, one of my logs pulled 9 degres on cyl 6 and another one pulled 3 across all cylinders exept for cyl 3 and occasionally ill pull no timing. Whats strange is in 3rd gear i pull literally 0 timing from 3k rpm to 6.5k. New plugs with index 12s and relatively new hpfp. Fuel trims are usually good staying between -1 and - 10 on the stft and around -1 to +1 on ltfts. Im leaning twoards the pcv being the culprit, as i occasionally will shoot a little puff of smoke after low rpm driving or idle but its wierd i only have issues in 2nd gear.

Based on your timing corrections and negative stft, it sounds like your ethanol content is too low. Can you try going up to E40? Do you have an upgraded LPFP? If so, i'd run up to E50 on that map.

I do have an upgraded lpfp, i also fixed all the timing corrections by switching to mhd v7 on e40. Either the e40 fixed it or the maps change. Thanks for the input.
