When I step on the accelerator a little, my car starts accelerating and suddenly near 3000RPM it slows down like I break hard and then it starts accelerating like I step on the accelerator hard.

Is this a calibration issue or is it something wrong with my TPS and/or Throttle Body setting (I mean the small screw which is limiting the throttle position at 0%)?

As I noticed that the engine is reving up although the TPS value stays at 0%

When I checked the display (engine stopped and ignition on), I read TPS values between 0% at no throttle and 100% at full throttle.

The car is idling perfectly fine.

What do you think is causing this?

Thanks in advence...

TPS signal don't seem to work

if you unscrew the TPS from the OEM Throttle and screw it to the new one, tkae a lot there...

the K series tps are really easy to broke

it's like a small sheet of porcelain

Thank you for the quick reply.

Is it possible that the TPS is broken?

look to see what the TPS is doing when you slowly move it while datalogging.

I tried rescaling the TPS in the KManager software and that resolved my issue.

Thank you for your help.

test your tps voltage at closed throttle. it should read .5 volts. i had the same problem after installing a BDL 70mm. the k pro was reading 0 and 100% but it was not at .5 volts. then the k pro said 1 and 109%.
i adjusted the tps, and then scaled the settings in k pro. it runs great now.
