Hello guys.
My head is ready to blow now so please need your help.
Friend's car, remapped, on part throttle (p.e. 30% wped_w) throttle angle is wide open ( wdkba = 100).
On wot as expected everything works as requested.
Dont wanna disable torque monitoring just a reminding what i forget to fix this.
KFMIRL -> OK
LDRXN -> OK
KFLDHBN | KFDLULS-> maxed
KFTARX | KFTARXB | KFTARXZK -> OK
KFLDIMX -> OK
KFLDRL -> OK
KFMIOP -> higher on high loads
KFMI_UM -> Stock, i thing here is the issue.
Going for sleep, hope to see the solution on my dreams or on this dream forum.
Cheers.

You want to REDUCE IOP, not increase it.

^^ that makes no sense, my tunes have always been stronger when increasing IOP when you want more TQ especially in the higher end of the load scale.

If you increase IOP, you will more likely have torque intervention if you also increased IRL

No reducing IOP will lower the torque on high rpms. Also is adjusted only on high loads which don't interfere with partial throttle. I ll look at this right now. Any more thoughts welcome  |

KFMI_UM has to be updated. I know this because without changing KFMI_UM I got a lot of jerkiness and also torque monitor 2 intervention.

He would have a code if he was experiencing level 2 intervention. IMO the *_UM tables never need to be touched. They only intervene when there are problems in the tuning. |

I've never seen this to be true if you do it right. I almost always have the last column of IOP @ 99.99 |

Explain to me then why cars that approach more the higher load values on the axis have higher TQ values? like in the RS4?
I'm sorry but if the last load # in IOP is @ or below your max load you want to have you want to make sure you're upping the values in IOP. It's always worked well for me and the engine most definitely develops more TQ. If course IOP changes means other things have to be changed to jive in the ECU. But lowering IOP in almost all cases neuters the car from what I've found.

I don't know what you mean by "develops more TQ" Do you mean torque intervention via timing retard is WORSE with lower IOP? IMO, that simply isn't possible. |

This. Re-scale axis. Problem solved. |

develops more TQ = the car feels much stronger.
Either way, there is a place for higher numbers in IOP as I've seen it in more then one factory tuned ECU before. Of course there are things to consider and like I said, everything must jive.
That said scaling up IOP towards the end shouldn't cause any part-throttle issues.

That isn't anything even remotely resembling objective evidence  |
