    The data log can only show the position commanded by the PCM. Unfortunately there is no feedback as to the actual position.

    Isn't the IAC actuated by a stepper motor…… rotates the pintle to screw it in and out. I wasn’t aware there is a spring involved.

    What ever the 6 piston kit is, 13" rotor. They're on the car now, next stop is to go by the body shop that painted it and make arrangements to bring it back to fix the rear quarter panels on it. After that charge the AC and drive it. I need to check the fluid level in the 12 Bolt, there is a leak at the axle tube. That maybe a next year project. I want to put the old brakes on my friends 96 Camaro SS, he has torque thrusts so he's a bit limited.

    On the throttle body, an extra spring was added to the throttle body. From what the tuner said, they said the spring on the blades felt like its lost some tension, so by nature when you depress the throttle it may not be opening smoothly or fluttering some what at part throttle, kind of jerky causing some bucking. He said the extra spring should give it a little more tension and make the throttle feel a little smoother. He couldn't find in the rpm range it would do it where it was fuel or timing issue. Seems to open up fine at WOT though
