boost numbers with torque app
What is everyone getting for boost? I just got the torque app and I'm only getting like 25 psi max I thought stock was like 32 or 34 on these cars. Is there an adjustment on the app I need to change?
Thanks |

Don't know, never had the interest to log it I guess
Was just curious, several other people have recorded a max of 26psi. Does the app convert the value internally or did you have to give it a factor? The DDE reports boost in hPa. |

Good question Hooper. Torque actually uses a "calculation" for its boost numbers. Relies heavily on the MAF input. In the Vehicle Profile, some things that impact boost accuracy include:
Engine Displacment of 3 litres, Volumetric Efficienty of 85%, and Boost Adjustment of 0. Try playing with those values. I played with those to bring the boost numbers inline with what the DDE reports (it reports absolute pressure by the way, which is normal atmospheric pressure + what the turbo adds). The DDE for stock mapping is 26.5 psi max. Both the Evolve and Ecotune remap raised this to 30 psi. Attached is a log from the Bavarian Technic tool recording directly from the DDE during a full fueling pull. |

On the service ticket it says "reprogrammed with no further faults found". I understand the new injectors have to adapted to the DDE (or the other way around maybe) but a complete rewrite of the software. Number 2, low boost numbers. Number 3, no regen yet. Mine used to happen every 250 miles. Number 4, subjective find... the car is not as lively as before. I will dyno it next week to see what numbers she can put out. |
