Hello Guys i have a problem with a med9.1.2 ecu i hope someone can help me or guide me to the right direction
I tryed to activate pop and bangs over the A/C button for this i changed
DNWEK to 8000rpm
Kftvsa/kftvsagi all to zero
KFZWM all maps in the low load to -25 from 6000rpm to 2500rpm
It pop and bangs really loud when i let the Pedal in the range 4000-6000rpm but around 3800rpm its stops but i can see in the cluster fuel is added the car accelerates slowly. When i push the AC button the car brakes i can feel it.
I logged the values and there i can see the timing jumps from negative to positiv and the pops are over.
When i push the button for example at 3000rpm and activate the AC it bangs for a few seconds after this i must push the button for the next time to make it this pop an bangs.
I hope someone can help

Good investigation.
The reason you didn't have to do anything in Ghidra is that Holley made this easy for you; that file is a Linux binary (ELF) with debugging symbols (DWARF) included as their build process did not remove them. So, they literally just gave you the names for everything for free. 99% as good as if they'd just shipped you the source code. |

I have a terminator X Max in my LS swapped Audi (hence the username) that I would like to send some inputs to the ECU such as when the AC button is pressed to increase idle RPM. I could do this using the normal wired inputs, I know, but I don't want to. Holley doesn't publish CAN IDs because they want you to buy their modules
 , and yes hindsight being 20/20 I should have bought Maxxecu or something else but I'm too cheap to buy another ECU at this time, maybe in future. I've seen devices such as the ones Holley makes, but also aftermarket products such as the BoostSmart IO, that can accomplish this. I found a firmware update for the 7" display and loaded it into Ghidra. Looks like the dash is using an ARM Cortex processor and can send sensor data inputs to the ECU (manual says telemetry for example) and this is done with several functions such as the ones attached I believe. I'm still pretty new to programming in general and especially disassembly but thought this was a cool find! Attached is the bin that Ghidra disassembled nicely. Still deciphering exactly how the Can ID is formatted for transmission because I know Racepak output from the Holley uses extended IDs and also trying to figure out how CanLookupTable for received messages is populated (for more projects) but I still wanted to share. I didn't have to label anything or set the base address and I don't understand how but numerous functions were named accordingly already once analysis was performed. |

Hi all. I replace my dq250 awd with a fwd gearbox and made my car AWD.
Old one was a cxx and works beautifull but now i put an fxx and it is more complicated. I have the same problem with a big lag/delay when i kick the pedal. If i drive normal and i keep the box in rpm all works ok and it change ok. In sport mode and manual or paddle modes it works greate. I upper the torque limits in the KusMMax_ko[K1] KusMMax_ko[K2] mmr_MMaxGetriebeschutz_ko MmrTemperaMmax_kl I made something wrong or i must modified other maps for this delay in drive mode? I attach my file , it is an 02E 300 013 HW: 02E 927 770 AL Component and/or Version: GSG DSG AG6 511 2249 Thanks in advance. |

Thank you, I wasn't sure if the Hw version being slightly different would be a problem..?

Hi everyone.
Hobby enthusiast here ! I compete in Sprint racing, have an Audi TT MK1 with a heavily modified engine on standalone. A friend is joining me racing next year and we are preparing a second TT with an uprated engine. As this is all on a shoestring budget, we have got a spare ME7.5.5 ECU to play with, |
