Ric Posted December 14, 2016 Share Posted December 14, 2016 if it's the same part number i'd expect they are the same. Quote Link to comment Share on other sites More sharing options...
Twin turbo Posted December 14, 2016 Author Share Posted December 14, 2016 Yes that make sense but some places it is written F/S EMS in the end Quote Link to comment Share on other sites More sharing options...

Twin turbo Posted December 14, 2016 Author Share Posted December 14, 2016 Yes same part number but use only these letters in the end some places where they sell them.guess the ems only collect the data it need on the newer engine since it is also MAF on vvti engine Quote Link to comment Share on other sites More sharing options...
TheTurtleshead Posted December 14, 2016 Share Posted December 14, 2016 VVTi engines use MAF not MAP. There is no MAP sensor on a VVTi. Quote Link to comment Share on other sites More sharing options...
Ric Posted December 14, 2016 Share Posted December 14, 2016 VVTi engines use MAF not MAP. There is no MAP sensor on a VVTi. You sure? The MAF for air flow where as the MAP detects pressure, the MAF wouldnt do that job. Im pretty sure VVTI have both sensors? and none VVTI just MAP Quote Link to comment Share on other sites More sharing options...
