K04 fueling project update...3.5bar fpr installed
I had been running a OEM bosch 3.0bar fpr with tt180 injectors for about 6months now. fuel trims have hovered about -0.6% and -6.3%. If you remember, I calculated I needed 3.3bar fuel pressure with these injectors. Logging showed that the 3bar setup was minutely better than the stock injectors + 5bar fpr, but still possibly leaning out up top.
I jumped to 3.5bar fuel pressure as an experiment to see if exactly 3.3bar is really needed, and if uptop the injector duty cycles drop to the "nice" zone. (the thought being if they are still not in the "nice" zone then obviously a 3.3bar setup isnt going to work either)
logs & CAPS times to come once I get some miles on this setup.
stay tuned
