Hello everyone, so i might be overlooking this but what's suppose to be the normal voltage to ecu for PIN 71 +14V?? My tuner told me that my the g4+ plugin was not seeing a good amount of voltage so he had made a jumper wire from the alternator positive post straight into the (B) Pin 71 thus ECU getting 14V, and had continued tuning my car like that. I eventually had to take that jumper wire off bc it would leave the ecu activated and drain the battery even after I would turn off the car bc it's straight powered from the battery. Right now I only see ~12.8V to the ecu. With car on i have 14V at the battery posts and alternator positive post to chassis ground. Battery is in front of the car, positive cable runs through the whole length of the car into the trunk where the fuse box is located. In picture provided, it's 13V at the 15A EFI fuse White/Red Wire to (Batt) Pin 61: 12.8V Black/Yellow to (+B) Pin 71: 12.8V Here's a log that I've recorded, ECU voltage varies bc of loads like lights, signals, fan, etc.. Can someone give me some advice? Log 2019-12-15 4;37;23 pm.llg
Please advise, I have configured An4 v as an input for my oil pressure. I am using a Gems 0 to 8 bar scale sensor with a 0 to 5v output. My issue is that I keep measuring 7.35 volts on An4 V which I think is telling me that I need to use a VDO Type resistor sensor. Not what I am after, Gems sensor is mounted and wired up except for the V88 input. How would I reconfigure this input for a 0 to 5 volt input please. Thanks.
Would like to understand how the G4+ interprets the following condition when using a voltage divider on an analog input for cruise control - i couldnt find the info in the help file. If the On cruise button (momentary not latching) is say set to 4v and it is held down then the ecu turns cruise on - if after this point the same On cruise button is held down does the ecu interpret that as cruise Off? Thanks, BR
