Hi I have logged my car on several runs, and the MAF is maxing out at 185g/s. What would be the cause of this? One of the logs https://log.tunezilla.com/chart/752080 |

Why would you post a link to some graphics page instead of posting the log csv?

So you think your turbo can do more airmass  . Maybe a wastegate duty cycle of 150% helps you out  . Okay, enough joking. If you want to cross-check if your airmass is restricted to 185g, simply raise your completely KFKHFM by 10% and lower your krkte by 10% for one run and check if it is still limiting at 185g or, suprise, surprise this time it is limiting at 203g/s  . |

Next time you should mention sw number. 018h has in deed a airmass limiter at 188.9g/s, see 1bfca. But it is not a hard limiter, it only limits your pre-calculation. |

Posted adress is okay for 360153, that is 0004 of 018H other public Version s 360283 with 0003 (not often seen). Edit: crosschecked, MLMAX is on both on same adress. |

thanks for the help so far.
Will make some changes and also test another MAF to rule out the MAF isn't playing up to.

thanks for this, when i look at this in winols it has a value of 144 (or 90 in hex) - do you know the offsets etc, to get it correct? |

I have logged my car on several runs, and the MAF is maxing out at 185g/s. Youre running 95% wgdc all the way, its just a limit of a turbo As for the low readings for a k04, check air leakage, probably maf issue. MLMAX are not limiter at all |

Will do, i decided to check the map sensor, as it has some strange part no and a bolt missing. replacing for an original one, and will do some new logging. |

Does this mean simply enter the maximum value of MLHFM in MLMAX and the limitation is removed on software side? |
