Plug and Play Flexfuel for N55/S55/B58 via BM3! The HE140i Gains Tech
Pro Tuning Freaks’ latest product is their range of Flexfuel kits for BMW F platforms, including N55, S55 and B58. The B58 is the very latest to join that line up and so we got kits straight in, ready for fitting to the HE140i. This kit allows for on-the-fly ethanol fuel content monitoring, which when coupled with any BM3 CustomRom map, also tweaks mapping to suit the ethanol content during driving. These kits are completely plug and play, and can be installed in no time. Incredible tech and available to order here.
