I'm having big trouble with this car. It's a 3-liter s4 engine and it has rs4 injectors, rs4 maf and rs6 turbos. It pulls all the timing and also the desired afr goes down, so I suspect this has something to do with torque monitoring.. I bet I did something obvioulsly wrong but i just can't figure out what the problem is.. And I really need some help. Maybe I will make myself look like an idiot, but hey, maybe because I am one?!  And have I done it anywhere near right with iop/irl maps? I've come to the point now, that Im considering pay one of you guys to make me a basemap, so if anyone of you guru's is interested, let me know! Thanks!      |

Your kfmirl and iop are completly crap, to put it honestly! If your struggling use the interpolator to get a good start. |

Okay, was afraid that i got that part wrong. I will check the interpolator if i can find it. Do you think it is iop/irl that is my issue? I just scaled it up manually as i thought it would be for higher load..
Thnx for your input! Really need some critics and tips now, and maybe i get how it works. Will do some more reading tomorrow, my eyes are bleeding now!

So, read some more and I hope I have some more understanding now.. These are my New IRL/IOP maps, haven't tried them yet though.. Any better? The only strange thing is, when I saved this I had 238 in last axis of IOP, but I see now when posting them that it's Down to 224  Will have to check this before flashing..  |

You need to read some more bud. Do it yourself, don't pay for a tune unless you really have to. Learning along the way is all part of it, and how most people here learnt the knowledege they know.
In KFMIRL you are saying that at 99.9072% throttle load is 238.7395%.
In KFMIOP you are saying that at 224.9814% load you will be running 99.7699%
Have a look at the standard tables.. You should quickly spot the relationship.

Bump the last column at 99% ped to much higher value -like 299 load and riverse in MIRL at 299 load you want 99% pedal. That way when your at WOT, you make sure you have all the load possible. This will later be caped with LDRXN...... As it is you ar not ordering enough Laod 238 |

238
299?! This car will not see very high boost on petol I think, the engine is a 3-liter built originally for e-85 so its on quite high CR, an the rs6 turbos will give enough air at low pressure. I know i can cap it with LDRXN, but now I have scaled up the last 5 lines in IRL gradually, and then used the interpolator to generate the new IOP. I will test with 238 and see if I get rid of the interventions and all first, then raise the load if needed. |

I understand your intentions, but it really does not matter which value you have in last load column as long it is high enough. Later on, you regulate this with lrdxn, and hbn and so on.

200% load on a 3.0 is much more than 200% load on 2.7L. Isn't there a maps for displacement as well, that need too be altered when going 2.7-3.0??? At 200 load, you should with correct timing be making some serious power on rs6 turbos??? |

About HBN, what should it be at? It isnt just a pressure limiter? I have raised it according to what i thought was a pressure limit..
All of a sudden now after dialling iop/irl in, i raised ldrxn to match my requested load and it did this time. I cant figure out why it didnt before when i tried to raise it. I still have some interventions and the problem i think is that i always have higher actual load than requested.
Is there maps for displacement? That's interesting! How big influence does these have, and which are they?

There have been dozens of threads about this already. log ldrlts_w (ChargeLimitTurboProtection) Is there maps for displacement? That's interesting! How big influence does these have, and which are they?
