JHM ECU or custom map
Posted: Mon Aug 16, 2021 7:41 pm
Ok sure this has been asked before however I'm not sure if anyone has a B8 RS4 running a JHM tuning box at all. If so what are your thoughts.
I was all for custom mapping but I've seen nothing but good stories about JHM.
I spoke to them today and they have an ECU tune for the RS5 that is compatible with the RS4 B8.
Im not looking for grandads to tell me to not tune it's bad for engine ect ect I'm fully aware and I like tuning as I want to gain quarter mile times.
Hoping to get some feedback from other people that have tuned these engines. With it been NA I've found it hard to find any mods and this JHM ECU seems to tick alot of boxes.
Anyone running JHM ECU on any other RS models
