Manfred Posted May 25, 2020 Report Share Posted May 25, 2020 Hi, I wired two switches to enable antilag and traction control to my expansion 1 connector (no E-throttle). Pin 2 of the switches has +12V and pin 3 is going to the digital input. Neither the status of both inputs will show active if the switches are enabled, nor the status LEDs of the switches between pin 3 and pin 7 will go out if the switches are disabled. If I disconnct the switches and the ignition is turned on, there are +12V provided from the ECU through the digital inputs. What am I doing wrong? Thank you in advance, Manfred G66.pdf 1_SubaruWRXSTIV8JF1GDBLH33G045680withlambdadata_switches.pclr Quote Link to comment Share on other sites More sharing options...
Adamw Posted May 26, 2020 Report Share Posted May 26, 2020 Go back to basic's. Unplug the expansion loom. Get a little jumper wire or paperclip etc and short the DI7 or 8 pin to the 5V pin that is in exp 2 connector - does your DI then show active?

Manfred Posted May 27, 2020 Author Report Share Posted May 27, 2020 Hi Adam, thank you for your response. I just had a look at the ECU board and I don't really get how the expansion connectors will work in different ways regarding with or without E-throttle. On my board the connectors are assigned like it's in the manual with E-throttle, but my car is drive by cable. My expansion loom was connected to the right expansion connector in this view. Thanks.

Adamw Posted May 27, 2020 Report Share Posted May 27, 2020 The “e-throttle “ refers to whether the ecu is capable of controlling an ethrottle system or not. Older ecu’s (more than about 3years old) didn’t have the aux 9and 10 outputs on the expansion connector which are required to drive e-throttle. All V7-9 cars are cable throttle from the factory as far as I know. Manfred 1 Quote Link to comment Share on other sites More sharing options...
Manfred Posted May 27, 2020 Author Report Share Posted May 27, 2020 OK, so the assignment on the board is the definitive pinout? That would explain why my aem trim pot worked using the right hand side connector, but DI7 and 8 not because they are aux outputs, right?

Adamw Posted May 27, 2020 Report Share Posted May 27, 2020 The labels on the board are correct Manfred 1 Quote Link to comment Share on other sites More sharing options...
