Tech Support HELP! New 30-1220 box in my TA... weird parameter behavior...

[Goldfinger911]

I just finished the install of a 30-1220 box in my 2002 F-body.
I followed all the directions exactly, I updated the firmware to the 1.21 as instructed, and loaded the Startup Calibration.
After uploading it, the IACV started making a pulsing/ticking noise. I looked at the "Setup" template and noticed that a lot of the parameters were surging... or fluctuating... and the car wasnt even started.

A lot of them... the TPS was bouncing between 0% and 4%... the MAP sensor was boucing betwen 95% and 99%... the Idle position was bouncing... several unrelated parameters bouncing. They were all fluctuating with the same "rhythm" as the clicking of the IACV. I then unplugged the IACV and the ticking stopped... however the parameters kept on bouncing.

Anyone ever had this happen before? I didnt want to start it... incase this is something major.

Thanks in advance.
