Just curious is 4d fuel corection negative numbers normal or not?
We have rb3.4/rb26 with id1700x injectors (dead time and short pulse adder taken from id site).
TPS table tuned to 0.8>0.6 bar spring pressure. Once I add boost it running richer then my target.Had to remove -15% of fuel at 1.2 1.6 bar.
Before 1700 injectors, there was 1000 bosch or denso and 4d fuel corections were positive.
