replied to the thread Car keeps blowing LPFP fuse. This aggression will not stand.
" Very, very helpful discussion above. Thanks. I’ll respond with my observations to some of the thoughts..
-Was not paying attention to how much gas was in the tank when the fuse blew, so don’t want to speculate.
-The 20 amp fuse blew once under medium load (4K in 5th gear, about 90MPH cruising), and once under more or less 0 load, close to idle cruising in traffic on the highway. So something is over driving it seemingly regardless of load. Which is odd as the fuel pump now seems to respond poorly only under heavy load.
-I’ve continued to make scalar adjustments and am now using a 3D scalar for E60. I need to verify the ethanol content at this station, but theoretically that is what is in the tank (famous last words). As noted prior, adjusting scalar was very helpful. The car now operates at a healthy LPFP PSI in all situations except after heavy load situations. It does not drop down from the 80s after seeing a lot of load. If the car is restarted, LPFP PSI returns to “normal”.
-I agree this combination is likely too much pump for my needs. Actually, I know it is too much. I bought this very expensive paper weight planning for future fueling needs which will be greater, what I did not consider was the potential for “too much” pump creating a significant problem. Suppose that’s on me. "
