Hi everyone !

Long story short:

There is one lad whos tuning stock subaru ECU's locally and I heard that people was complaining about his tuning.

Car runs good, but only for short period of time it could be hours of driving, but after some time engine goes in safe mode.

There was customer who send his car to other tuner to check how good he done his job.

He said that values he found destroying engine.

This tuner provided screenshot as proof of incorrect values.

Is it possible to identify by screenshot in attachment, that something there is very wrong there?

I'm thinking to warn other people that they need to retune theirs ECU at other place and want to understand what is not right there.

Many thanks,

Hello i am not able to go on a blame or name and shame but the ignition number do look very very high to what i would expect to see

i would suggest the tuner be invited to Hp Acadamy

Thanks Ross for a quick answer, guy whos into it (proper tuner) said that stock settings also not good and should be below 50 as factory settings done by Subaru were primary set to values to reduce emission.

Your opinion on that ?
