Changing fuel pump CP1 R70 to R65

by **MothaHDI** » Mon Jun 01, 2020 4:34 pm

Hi again! So the current state on my car is that i'm always getting the famous P1112 Error (Low fuel pressure on high pressure rail). I' trying everything to fix this, i've change alot of parts including the most common ones like the fuel pressure regulator, injectors, change pressure deviations and pre control map on ECU and did a bunch of testing. NOTHING works :problem: so, i have a R65 fuel pump that i know is is good state and i wonder whats the max IQ it can get on a 2.2L.
Right know i cant pass the 80IQ mark on my car, should i change to r65 and keep work my file after that? I only need to change the Pre control map and the main rail pressure map right?

PUG 406 2.2HDi EDC15C2
