Throttle too sensitive when on to off

[Tim ma]

My DC5 type R just installed a Kpro with base map K20a.
When driving the car 1-3gear low speed at 2-3K rpm, then close the throttle to 0%, it was stop accelerate very suddenly, no need to use brake to stop behind the traffic light, the engine brake totally too much for daily drive, i have no idea whether this is setting problem or calibration issue.

Anyone have idea I appreciated

Post your calibration as well as a datalog showing the issue.

Has this been properly tuned on the dyno?

It is normal when the throttle closes and you are decelerating for the injectors to cut off.

If this is normal, it must be the problem of daily drive, big difference between stock ECU when throttle closes, it is stuck when get into traffic jam

You may also try adjusting the idle solenoid duty if you feel the rpms are dipping too greatly.

Tehlonz, i don’t get yr meaning, adjust TPS angle or idle Rpm?

Your support appreciated
