        Yeah, i dont have the afm or a maf so i have a stock tps, air temp sensor, and the map sensor ofcourse.

        But the crank sensor had too big of a gap so now it runs fine

          yeah, sorry I didn't see this earlier, your datalogs indicate that MS was losing timing(hence the drop to 0rpm at 5k). oil on the trigger wheel, big gaps, and shitty shielding on the wires can all cause that issue. If you have more issues of random sync losses, you need to consider moving your CPS wires, or shielding them with something else. Or moving to a hall sensor.
