Regarding timing; if it's added, thus increasing engine torque at load X, will the respective changes need to be made in IOP load point X or is timing factored in internally and torque "corrected" before the final torque figure is reported? Tried reading the FR but couldn't figure this one out, hoping this can help myself and others get a grips with correct torque reporting!  |

Look at ignition angle efficiency calculations.

I've searched and searched, I can't figure it out  Could you point me in the right direction? |

Open the Alfa ME7.3 english FR and look how miist_w gets calculated.

miist_w is the output of KFMIOP which is corrected by lambda and ignition angle efficiency (mdverl_w?) by subtraction and then the result is multiplied by MDNORM to make torque, I need to look into how mdverl_w is calculated.  *edit I see mdverl_w is motor torque loss so miist_w is where the lambda and ignition angle efficiencies are factored in, that's why you suggested it lol |

This is a new information for me, so thanks for sharing. Currently i'm struggling with my dsg DQ250 on my audi s3 8p. I've had a dsg rebuild (new flywheel, new oem clutch pack, cleaned mechatronics, new filters, oil, etc.) After rebuild, if i use more than 60% throttle, the car "push/pulls" between shifts. No clicking sound or anything, just the little stopping between gears at high load. Any idea whats the problem? I have stock ECU and TCU software. The car is stock except a decat downpipe, lambda(1) is on the car still, lambda(2) is not connected, and it throws check engine light also. Can it be the problem? I thought lambda(2) is only for correction and the lambda(1) is what really matters. +1: Anyone knows what is the standard clutch pressure? The car only pulls above 10-10.5bar clutch pressure, its very smooth with 9.5 bar, same torque logged at both pressures (370nm), just higher throttle |

Hey. Is there a table for clutch "grabbing" RPM vs throttle pedal % when taking off from a standstill ?
What are the names? I have to alter these so the car dont roll from standstill uphill, needs to be done for D and R. |

If you make it too low you will have huge turbolag and if you make it too low at low pedal angle then you will stall/bog the engine. |

Depending on the car and abs model, you need to enable/retrofit hill hold assist. |

I dont want to do it with autohold, i'm going to try with standstill maps. |

Hey,
I'm trying to change shift points in Fxx Superb 2.0TDI 170HP, is this correct way to make it? Names/id's in mappack may be mixed up, I was guessing correct map by RPM's.
Here is dump (ori/mod/kp)

Yes - there is way. You need maps pointing in correct locations. Two ways to aquire that - find any floating in internet ols and via map search nail it to required locations, second - buy mappack or use any online tool.

Hello! I'm new to DSG mapping and experimenting with my Passat B6 DSG DQ250 Cxx. I have a mappack with which I managed to raise the torque limits, the switching speed and optimized the switching points, but there are several things that are not clear to me, for example, is it necessary that if I change the torque limits, I must also change the maximum revolutions and what is the logic ? I also have a noticeable reduction in torque when shifting to 2-3 and 3-4 when smoothly shifting in Eco mode. The idea is to optimize the box for smooth and soft shifting while at the same time being fast and responsive.

Can someone point me to the tables that force upshift in TT ONLY on wheel spin? Normal/non spinning is fine, but wheel spin forces an upshift. I have removed every other nanny so far.

Hello, I have DL501 not DQ250 but I am searching hard for help with a shift issue. TCU tuner cannot help. Can someone please help me with how to properly output tq to tcu?
Or point me to some documentation I can read. There was a lot of great info in this thread. I am tuning ECU on DS1 Dynospectrum to flash and tunerpro to modify bin. I do suspect that some of these tables mentioned are missing from my xdf so thats likely why I cant find them. I attached my bin for review, in case anyone can help.
Thanks!
