The uncorrected TPS is slowly changing from -1.7% to 1.3% during the datalog.

How do you get 2300 rpm with no throttle?

it looks like a vacuum leak or somethign is making your throttle body open. CHeck teh tension of the cable to make sure that it is not too tight.

the problem was there the car was at idle and i press the pedal up to 2300-2500 rpm and only the TPS start reading
i have check every things like the cable/cable bracket at throttle body, BDL 70MM throttle and its confirm no leaking around RBC intake and the BDL cause its was idle constant at 1000 rpm

and now i was found another things when WOT the TPS was reading max 94-96% and i check it again its was fully open nothing wrong with the cable and the pedal and also the bracket

could this was ECU faulty?
that's was lots of knock count but the motor was still on tuning and found this problem

This is not an ECU problem. It is either a problem wih the TPS sensor or more than likely a problem with the throttle body
