came with the car when I purchased it.

Hello, I have a weird problem with my speed sensor readings. In my datalogs, I noticed that my VSS line is very erratic. For example when I do a street pull the line looks like it’s something from a heartbeat monitor screen. This erratic speed that krpo is reading also affects my 2step. It will stay in 2step for maybe a second and comes out (revs to revlimiter) because it’s coming out of the speed parameters in krpo.

I changed the sensor with no success. I never had this issue before until a few days ago. Anyone have some input on this? Thanks.
