WRX coes very lean in OL. help


I need some help in order to understand where is the problem.

The car has lean spots during mild acceleration.

AFR is jumping to over 15

Time in the log 22.56 to 23.04 is a good example.

Please see the log file

The car is 2001 WRX with modded injectors, silicone intake, VF43 and S202 like tune on H98 europe fuel.

Not sure if this is your problem but sometimes modded injectors can have flow variations.
