tuned an 06 Si on the dyno today. 320whp/215tq at between 9-10 psi on a mustang dyno. everything went great made good power. during last pull , it threw an MIL for knock sensor circuit malfunction. ever since this , its pulling a bunch of timing and making the car run stuttery. the map is calling for 22 degrees , and its actually running like 10. i disabled the knock sensor , same thing.
i have quite a bit of experience with kpro ,flashpro seems not nearly as rock solid as kpro , and far fewer options. any help on this please?
