I've just installed a link G4+ into a standard V6 WRX, the vehicle ran fine on the factory ecu, I am using the base map file as supplied for the ecu and this model, running in traditional mode.
The problem I am having is the car gets to around the 3.5 to 4 thousand rpm range and feels like it cuts fuel, my lambda reading goes lean no matter what adjustments I make to the fuel table,the car holds back and pops out the intake, it feels like a trigger issue, there are no fault codes being logged by the ecu either, I've turned off all engine protection just as a test and still no change, also have updated to the latest firmware, the car is around 11.5 afr when it happens so certainly not a fuel table issue. Map and TPS all calibrated, just need some extra ideas to check.
