is it possible to log the LPFP and the HPFP pressure with procede 2.5?

I am running out of fuel and trims are maxed out at 35% around 3500 rpm.

07 335i FBO stock turbos with 100% 95 oct gas

new 1M HPFP

old injectors

old LPFP and fuel filter

only 40000 miles

What date maps are you using? And what PSI is it maxing out at?

[marconi118]

latest aggressive maps, maxing out at about 11psi

maxing out too with jb4 going over 11psi

I read you need a surge tank and a boost a pump.

Sell one of the tunes and try Cobb and report back to see trims.

No its not possible to log LPFP or HPFP pressures with the procede as far as I know. You can with Cobb though.

You can log high pressure fuel sensor with the PROcede, but the data is in voltage and i cant seem to find the correlation. I'm Hitting a fuel ceiling as well at 15 psi on the aggressive maps with OL fuling at 100% however my trims go from +35% to -25% in the same pull....

The units are Voltage 0-5V. and from what I've gathered data wise its ~1.3V at 720psi (@idle) so that would come out to a ~550PSI/Volt if you assume a linear scale... which may or may not be a good assumption. The OBDII scan tool updates once every minute or so when the procede is running so i have no way to test the scale.
