    02 Z06 2 bar SD traction control problem

    I am working on an 02 Z06 with an ECS ati SC and a 2 bar SD tune. When I hit boost I get an active handling and service traction control error. It also throws the codes

    C1278 TCS Temporairily inhibited by PCM
    C1241 Variable effort steering circuit malfunction.

    It also went into reduced power mode but I think I fixed this by upping the values in the P1514/P00068 tables.

    Any help would be appreciated.

    It was on the road. I changed the P1514/P0068 values and the problem has seem to completely gone away.
