You may start by cutting your stock values (if different) and use the percentage i applied. Vehicle speed table is 90% from stock basic correction table is: first three rows is stock (may be 90% will work here also?! i will try) forth is 90% from stock rest 0 Quote:
What will the software number tell you? I will update tomorrow. |

I tried those values and they are perfect. Not tested for stop start driving yet but for everything else they are solid.

With regards to your observation above, I noticed something strange when the car was in "P". If I hold the accel pedal constant at around 10%, the revs will spike up to 1300 momentarily and then dip back down to 1000. It's almost as if there's a boost on the pedal upon initial application. That would explain the strange behaviour when pulling away. I get the feeling this is a stock feature of the car. |

Any updates on I8 bugs/testing or upcoming MHD integration schedule?

There would need to be a lot of testing before they add it into the maps and it doesn't seem like anyone outside of this topic is interested. Quite surprising really. This is one of the most significant finds for years, it transforms the driving experience of the car. It's pretty big for DCT cars since it fixes the dead throttle input at low speeds which is one of the main complains of the transmission. Things like exhaust burbles are useless and add nothing to the car but had multiple topics and massive uptake. |

Ah, but I'm not after updated OTS maps, but adding this to the flash options. Or after info on how the testing, if any is in progress, for I8 is moving forwards so that I could ask my tuner to make these mods + others needed for my file if we are nearing a solution(s) to the previously reported issues.

Completely agree. MHD needs to offer this ASAP. Can't count how many times I stab the throttle during a downshift and the RPMs don't rise enough to ensure a smooth clutch release. Our E46 doesn't have this problem with delayed throttle response which makes the programmed delay in the E90 even more obvious. My 335 is a N55 but really need this feature. |

Seems like a lot of guys have been testing the I8A0S changes with no issues after driving their cars for a while (other than once off errors, if at all)
Have updated the original post with the dropbox link that contains IJE0S, I8A0S and IKM0S xdfs https://www.dropbox.com/sh/e4d01nmbs...WqCVls7BfBPmEE

I just read this entire thread from a link posted today on ***********. Glad to see these developments and hope to see it implemented soon as a flashing option in MHD.

I’m currently running the MHD FlexFuel module with the MOTIV FlexFuel unit. I’m self-tuned using the FlexFuel XDF. How would I access or add these new throttle tables to the FlexFuel XDF? jyamona ?
Thanks. |

Download the XDFs with the defined tables above, open your rom in the corresponding XDF, make changes and save the bin. You can add the tables to the XDF you normally use with copy/paste via text file or define them manually through TP editor.

The annoying lag between when I jab the pedal and when the car actually revs has always bothered me. I'm not tuning or coding expert, but I'm really looking forward to this!
Is it for sure going to be an MHD tickbox option soon? Otherwise, could someone make the changes to my bin file? If so, please PM me. I am using a free OTS JB4 BEF from N54tech.

Here is my bin file: https://drive.google.com/file/d/1Z8u...ew?usp=sharing Have the updates already been made to it? BMS noted something about the throttle being changed in this file.

No, this is a new table discovery that determines throttle opening delay or damping over time.
