Good day everyone I have an issue that I am trying to sort out. I recently installed an ECUMASTER Det3+ but I have a slight issue with the AFR. I have an AEM UEGO 30-4110 connected to Analog 3 of the DET3+ and grounded to the ECU ground on my 5EFTE Toyota Starlet Glanza together with the ground and power ground of the DET 3+. The AFR on the gauge is different from that displayed on the DET3+. When the gauge shows a value of 16 AFR the DET3+ shows a value of 14. Has anyone experienced this and how can this be rectified?
Make sure the scale of the analog 3 input
