    Default No Kickdown?

    My PCM does not seem to be responding to the throttle kickdown tables. So when part throttle boost kicks in the engine just loads up, resulting in knock. In the screenshot below kickdown should have occurred at around 32% TPS but didn't happen until close to 70%. Did I screw up or is something else going on? I also tried playing with the TCC release vs TPS table to no avail. Factory values are all set to 100% in that table.
