A quick explanation video of what I suspect is happening.

I am getting a error message when i perform a calibration on the throttle body.
The error i am getting is error 16 - cannot reach target 98%.
Setup is : 
V88
Bosch 82mm throttle body.
VE commodore pedal.
In the runtime values the pedal is reading alternate sweeps on both FPS(main) and FPS (sub) correctly within .46v to 4.7v and calibrates no problem.
During initial TPS calibration it will do a sweep showing 0 - 100% values with TARGET values matching. When it reaches the TPS main and TPS sub calibration stage that is when it faults. The Target value in the runtime shows 97.4%. Have tried a variety of PID settings with no improvement.  When it faults the throttle body stays at approx 100% until power off.
Voltages on the TPS are with .3v to 4.8v
Have manually tried to put the throttle body into 98 - 100% during the calibration stage just before it faults with no change.
The E-throttle target map is a FPS Vs Rpm 2 cell basic setup map vipec settings.
Which settings are being missed in the process causing the safety shutdown of relay for throttle body.
 

Hi,

Im im trying to setup my E-throttle with this configuration :

LS2 - 2005 Corvette engine
Standard E-throttle body with Chevy Equinox FPS (6-pin)
V88


The FPS Calibration works perfect. My problem is when i do a TPS calibration i get Error 16 : Cannot reach 98%

When the cal starts i the Main runs to 100% and Sub runs to 100% but then when they run together (step 8) i get the error message. My the throttle body seems to "snap" between 95%-100% repetitively on this step.

Can anyone give me some details,advice on how to setup the PID Settings for the LS2 Throttle body.
