David Tychsen-Smith Posted May 28, 2015 Report Share Posted May 28, 2015 I know that in PCLink the ECU settings for An Volt 1 can be changed to a different input and sensor type. However An Volt 1 has no pinout other than those wired directly to the internal sensor. Is there any reason why I cannot just connect to these pins off the board? I have a GM 4 bar map sensor that I want to use but have run out of non-essential analog inputs. I would like to use An Volt 1 and remove the old 2.5 bar sensor from the board. I can’t see any reason why this wouldn’t be possible (obviously not expecting it to be covered by warranty or anything). Can you provide me with the information for the pinouts of the existing sensor so I can wire in my GM sensor to match? Thanks for your assistance, Dave Quote Link to comment Share on other sites More sharing options...
David Tychsen-Smith Posted May 28, 2015 Author Report Share Posted May 28, 2015 I did just find that someone else has asked a similar question recently and it is possible to wire directly to the board in place of the old senor. If I could please get the pinout information that would make what I’m going to do more straight forward. Thanks again, Dave Quote Link to comment Share on other sites More sharing options...
Simon Posted May 29, 2015 Report Share Posted May 29, 2015 Best to just measure it on the board. All you need is the 5V ground and Signal. I'm assuming its a plugin ECU you have. Â Quote Link to comment Share on other sites More sharing options...
David Tychsen-Smith Posted May 29, 2015 Author Report Share Posted May 29, 2015 Yeah that's right, it's the Nissan GTR plugin ECU. OK no problem, I'll just probe the pins and find which one varies when an air compressor (at low pressure) is applied to the on board map sensor to find the signal line.
