V46.11 after removing dtc, wont idle smooth

[rob h]

Hello guys,

Peugeot 208 1.2 puretech.
V46.11. I removed dtc p0420.
Read, and write by obd, using magicmotorsport. (obd is the only protocol. Allientech can boot these full)

Now, when idling, it is hicking up and down, dropping from 900rpm to 700rpm.

I wrote back the ori flash, and still the same problem.



After a obd writing, does Magicmotorsport reset all learned values?

( i popped in another ecu, and emulated pin, to emergency start it. With this ecu, it runs smooth)



So i popped in the ori ecu. An did a few resets, cams, intake, etc. No improvements.

My guess, mms did reset all learned values. And intake polution, is getting in the way, off the full ranges needed to reset throttle valve etc.



Any experiences, and perhaps solutions.
