JB4 and TTFS HPFP?

StuyMac · 10-18-2019, 08:43 AM

Can you just fit a TTFS HPFP and the JB4 will deal with it?

Do you require anyother calibration changes, or change any settings in the JB4?
This would be on a 2013 F31 335i (pwg).

Thanks

it will depend on the tune of car , the jb4 only tricks the car into making more power , jb4 doenst control a hpfp , your ecu does that

Probably need to make adjustments in the back end flash for the pump to operate properly.

I heard that you will need a flash tune to get the voltage and the flow rate to work properly.. Jb4 can't do those.

Thanks guys. I knew that was the case, but with new firmware etc as thses things become more popular thought it was worth an ask

Would suggest stacking mhd with the jb4. That way your ecu controls everything properly and the jb4 handles the boost and logging. Cheaper then buying a stand alone flash. Jb4 back end flashes are free. You would just need to buy the mhd flashing license, which is like $250 if i remember correctly.
