I pulled the tape off and the wiring is twisted together. But it has definitely been snapped in the past and looks as though whoever had it just tried to twist it together and then taped it.

Assuming your pins are fine on your new mechatronic, it seems like you might've found the issue on your gear shift assembly? Maybe try splicing those wires to see if it fixes your issue and then pick up a shift assembly from a junk yard. I like using www.car-part.com, if you haven't heard of that before it's a network for junk yards to post items they have for sale. For reference, here are the forum threads I looked at: https://www.e90post.com/forums/showthread.php?t=2078744 https://www.e90post.com/forums/showthread.php?t=1683625 |

Idk if i can redo the wiring im not very good at stuff like that. But yes i bought the software like konistat suggested i do and i was given those codes. I had bought a shifter off marketplace and the wiring was electrical taped together lol. It was tucked and I was a dummy and didnt pull it out to really check.

Pick up an inline splice connector for now. WAGO is a decent brand. Probably not rated for automotive vibration but then you’ll know if that’s your problem |

If pushing over 500whp I’d go with at least 1 step colder. 2 steps above 650whp as well. Those are rough numbers. Get some fresh Eldor coil packs as well if you don’t already. Don’t forget dielectric grease to prevent an annoying stuck coil boot on your plugs

1 step colder should be fine. 2 step will work just fine too, might decrease mpg. |

That’s a hefty snail you got there. Try 1 step colders and see how those do. If your boost is above about 25 psi then 2 steps might be the better option but maybe overdose will chime in. Good move on the B58s plenty of spark energy

I am still somewhat new to these so please excuse my ignorance on these. I do most of the work myself and am still learning. On 91 octane im running 24 psi and on ms109 i run 32 lbs of boost. The car has not misfired on high octane so i did not take notice of the plugs and was running bosch. My fuel trims are also +/- 3 at most

Op you can always log the car where you want and keep an eye on timing correction and miss fire before changing stuff. make me crazy when people changing everything, like adding a dual fuel pump and never check if it's needed. |
