Aaron Wood Posted 18 hours ago Report Share Posted 18 hours ago I have a Link G4 storm fitted to SR20DE with ITB's (N/A). TPS on the load axis) Still running a dizzy and have fitted a returnless fuel system (for multiple reasons using the popular GM filter/regulator unit). Fuel pressure sensor is fitted and working. Is there something I can set up to account for the fixed fuel pressure? Rather than referenced to MAP or does it make a difference for NA? Noting that my map signal is pretty erratic. Or have I made a mistake on the fuel system and the G4 will never run right and I need to upgrade ecu to be able run this. Quote Link to comment Share on other sites More sharing options...
Adamw Posted 16 hours ago Report Share Posted 16 hours ago No it will be fine, the variation will just be baked into the fuel table. It is fairly common practice to run NA ITB race engines with fixed fuel pressure and no MAP reference to ECU or FPR. Quote Link to comment Share on other sites More sharing options...
