Default Hybrid Twins BEF Pump file not found. - 05-15-2020, 01:39 PM

It appears there is a Pump BEF for stock turbos but not for hybrid twins. Looking for a BEF for I8A0S. (2008 BMW 535xi)

Run the race BEF? You should be ok on lower maps. 1, maybe 2 if your pump gas is quality.

There is no backend flash for hybrid turbos on pumps gas. There is one for e85. For 91/93 octane on hybrid twin turbos your suppose to run the normal pump gas back end flash for stock turbos. I had this same exact question a few years back when I went with pure stage 2 turbos and this is what I was told by bms

pure stgae 2 DD turbos, rb inlets, bms 4 bar map sensor
Jb4 with mhd hybrid e85 back end flash, vrsf down pipe vrsf 7" intercooler, vrsf charge pipe with tial bov and afe intake. Fuel it stage 2 pump and fuel line/ethanol content kit.
