awah Posted January 23, 2021 Report Share Posted January 23, 2021 I have recently upgraded from G4+ WRX V4 plug and play to G4X XtremeX standalone. Previously, on the G4+, wheel speed was reading very steady there were no issues. On the G4X, the speed shows to be erratic, jumping around about +/- 1.5%. This causes issues with cruise control. The test was performed with both ecu on the bench, using the same wiring and same speed sensor - rotating with a cordless drill. Please see details in logs from G4+ and G4X.
