damen Posted September 18, 2023 Report Share Posted September 18, 2023 Hi there- I'm installing a G4X XtremeX on my GD Subaru racecar and was hoping to double check which base map to start with. The engine is a fresh rebuild with the 2.5L block and the USDM 2.0L heads with non-AVCS cams and single reluctor type cam trigger. From what I understand, the trigger mode will be the Subaru V7-V10 (JDM), but for first fire up, which of the 8 or 9 "Subaru ..." will most closely match this engine? Thanks! damen Quote Link to comment Share on other sites More sharing options...
Adamw Posted September 18, 2023 Report Share Posted September 18, 2023 The V7/8 or 9 map will do it assuming it is a cable operated throttle, there is very little difference between those 3 maps. And turn off the VVT, the TGV function and the 4D fuel map assuming you no longer have TGV's. The V7-10 trigger mode suits the 36-2-2-2 crank wheel with the separate 2 tooth cam sync wheel at the front of the engine. Quote Link to comment Share on other sites More sharing options...
damen Posted September 18, 2023 Author Report Share Posted September 18, 2023 Thanks for that- I'm running the DBW setup from a USDM 2008 WRX, both the accelerator pedal and the throttle body. Quote Link to comment Share on other sites More sharing options...
Adamw Posted September 18, 2023 Report Share Posted September 18, 2023 Id probably start with or V11 map in that case since the throttle and idle control set up will save a big part of the initial setup time. Just change trigger mode to V7-10, turn off VVT, TGV, 4D fuel and anything else not relevant such as MAF, PS switch and cruise control.
