May I ask why you wouldn't consider the BimmerBoost/Bms backend flash? Other then the cost of a BT cable, their back end flashes are free and Terry updates each back end flash every time he releases a new Hex file to go with the Jb4 N54 Iso piggyback.

Hoosain, please can you elaborate in what way it changed? Did you have a jb4 before and now you using the bms backend flash?

Thanks :thumbs:

yes i had jb g5 iso before
i did the bms backend pump flash
the car targets between 15-16psi on pump fuel and the car targets the boost much earlier in the rev range
car feels like shes on nitrous
i then mixed 30% ethanol and the car targets 17-19psi
previously with jb alone in 4th gear the car used to drop boost by at least 2psi its now holding boost without a drop

did some logs and everything looks good

Thanks very much for the offer George!

I am going to buy a cable soon as I still have motorplan so that I can easily remove the tune and also for updates

Thanks again :thumbs:

mmm i work with rob from vishnu, we will do logs on the car and from the logs he will develop a file for the car.. not off the shelf files .. so yea if that answers your question
