Dear all,

Sorry if this as been discuss before, but I would like to have your opinion on this.

Today I did some road tests with my mini copper 2009 JCW with 180.000kms on the clock and stock engine and from data logging in WOT I got:

- Throttle actuator: 90%
- MAP: 28.7 PSI
- "Calculated boost" ( from the Car Scanner pro): 1.05 Bar
- MAF: 154.11 g/sec
- Fuel rail pressure: 12.410 kpa

Regarding this data, is it normal for a stock engine or is it under what should be expected?

best whishes and happy new year

Sounds about right to me... What is your altitude? MAP and boost pressure are about the same, assuming an altitude of ~2500 ft.

Is there a reason you think your car isn't performing as it should? 180,000 kms is enough to see a performance degradation....

 

Thank you for you reply

My altitude is sea level Bar pressure today is 1021hPa

No particularly reason but I'm planning to do a Stage1 and once of the things that caught my attention is I cant get 100% throttle actuator during WOT. However, if the car is not running and I press until the end the accelerator pedal, I can see it at 100%.
This happens also with you?

 

I don't have an N14, so my throttle mapping might look different from yours. I do know that these cars use an "Engine Load" calculation to determine throttle and boost pressure targets.

Do you have a tuner that you're working with yet? Reach out to @Lou@Prototype-R . He has built a massively deep N14 database of knowledge. He might even be able to help you with some pre-tune data logging to determine the health of your engine.

 

Thank you
