Just to let you know...i've found the problem why the car won't open the throttle... The owner has changed entire engine and sensor with a CDLx ...but ecu was still for ori car BYD ... and at the end some sensors were not linearized. I've flashed a new ecu of a CDL engine and now works everything like a charm  |

KFLDHBN is another limit. What load are you requesting in KFMIRL and LDRXN? It would be helpful if you post logs

Also that level of boost will never be a target without some serious code level changes. |

This is true, your requested will never go over 2550. But at least you should get your request up there and then drive wgdc manually if you wish to go higher |

Have you even looked at the factor??? You will never request more than 2550mbar on this ECU without modifying scaling on plsol and other things. |

He is saying that changing just the maps is not sufficient, you need to hack the code to do it right, look at the 5120 hack threads.

I think you need to go read the S4 Wiki again, it's explained there why you won't be able to request over 2550mbar and like the guys said, if you want closed loop boost control above 2550 then you need to do assembly code changes (5120 hack). Otherwise the S4 Wiki does talk about open loop above that limit if you want to do that |

You cannot do it solely by altering the maps. |

I willing to pay for solution, for info about this, or someone to make it, or any solution that can solve the puzzle how to boost more, Thanks |
