i changed the tb , but still im getting the same code, and i tried to disable the code but it didnt help.
i dont know what to do but some of my freinds saying to set "p0121 error max map" to 100kPa and set "p0121 error min map" to 0kPa in order to dissable the test for p0121 in the hp tuner.what do you think about that?
