graph looks ok although boost gauge says it overboosts at 1.8 bar..it used to go to 1.4 bar..
also wastegate duty cycle seems weird...
i am suspecting that MAP is faulty and reading boost lower than it actually is...

 

[james walker]

you need to copy from excel and use code before and after to post the logs.... cant read those ones mate

 

[tstrahonja]

ahh..dont have excell
ill get it installed i guess...
but how cant u read it?
i can clearly see columns and numbers
8th column from the left is wastegate duty ranging from 54.9 to 85.5..and on every log i found on this forum wastegate duty is around 80%....not as low as 55...

 

[james walker]

harder to read when not through excel and blocks listed nexto each other for comparison, also the runs stop at 5400 rpm not the redline mate.

what gear were the runs done in?

 

[tstrahonja]

yeah i didnt have the balls to go until redline cuz my boost gauge showed 1.8bar peak...
it was 3rd gear pull

this is the best i can do so far...

 

[tstrahonja]

anybody?
