Which is fine except no where on the net can I find a pin out for the standard map sensor If anyone can shed some light on which wires which on the stock map that would be amazing f Cheers Quote Link to comment Share on other sites More sharing options...
Jefferson.C Posted October 21, 2019 Report Share Posted October 21, 2019 The factory Neo uses a MAF sensor. It does not have a MAP sensor. Use the on-board plug&play ecu MAP sensor. Quote Link to comment Share on other sites More sharing options...
Brad Foreman Posted October 21, 2019 Author Report Share Posted October 21, 2019 See attached picture . It does have a factory map sensor labeled "boost sensor" which factory is only referencing boost pressure no vacuum ... But as it says when using a link g4+ plug in it works as a map sensor if plumbing to the plenum so it sees vacuum and boost . if no one knows (surely someone has upgraded the map sensor before) I'll just have to trace wires Cheers in advance Quote Link to comment Share on other sites More sharing options...
