4b11 plus turbo problems

Postby Kvalderama » Mon Aug 08, 2022 4:36 am

Hi iam just finished adding a turbo on a '17 lancer gta and having some problems.

Rough idling even if i drove it for an hour to relearn the ecu, also it has a cel codes p0068 (maf, map, tps correlation) and p061a (torque monitoring). The ecu is not flashed yet. Anyone with experience could chime in. Thanks

It sounds like the car is throwing codes due to the increased airflow for the map, maf and tps. Its most likely due to being outside the values the ecu has predefined. The two codes are related. I would get the ecu tuned and that should sort the issues.

Yes this is a left hand drive

Yup i have to study how to reflash, i am used to standalone systems where open loop tuning is straight forward

Do i have to replace map sensor? I am not planning to boost above 1 bar.. could a stock map sensor handle below 14 psi?
