Say Hi to Carol for us! The guys and girl over at RC are great! Great work Shiv and team!

OT, but do we know if the X5/6M suffer from HPFP failures?

With the impending increase in fuel system capacity, it would be particularly awesome to integrate mapping for ethanol blends into the fuel system (E85+pump mixes). Or even go all out with a sensor that inputs into the procede, and automatically adjusts lambda for the change in ethanol content. Talk about a fun way to combat rising gas prices!

If indeed changing the voltage curve for the fuel pump controller solves the fueling issue, flash tunes need to find that table in the dme and adjust it. Most likely the LPFP controller uses a load vs rpm map to specify pump voltage. All that needs to be done is to adjust that map up so the pump flows enough for said load/rpm. Cobb better get busy finding this table

I will guess that the lpfp even going wide open does not flow enough and might need to be upgraded anyway. I am curious to see vishnus flow sheet for the pump

This is exactly what I've been thinking! YES!
