dave88sw Posted August 12, 2015 Share Posted August 12, 2015 Hi, can anyone tell me where is the best place to take the vacuum to the MAP sensor? I presume the dizzy vac advance is unsuitable as it's the wrong side of the throttle butterfly? Thanks Quote Link to comment Share on other sites More sharing options...

FridgeFreezer Posted August 13, 2015 Share Posted August 13, 2015 I used the pipe on the other side of the plenum - 8mm push-fit: Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted August 13, 2015 Share Posted August 13, 2015 I used a spare nipple on the other side of the plenum, I had 3 ports, only using one as fitted in an RRC now with ABS, so no servo. Quote Link to comment Share on other sites More sharing options...
dave88sw Posted August 13, 2015 Author Share Posted August 13, 2015 So as long as it's somewhere on the plenum and not before the butterfly like the dizzy vac advance all is good? Thanks guys Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted August 13, 2015 Share Posted August 13, 2015 Yup Dizzy take off is actually after the butterfly, HOWEVER there's a lot of turbulence there due to the butterfly, so readings can be bad, so one of the other places are much better Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted August 17, 2015 Share Posted August 17, 2015 Just don't take it from the servo line as those often have a 1-way and/or anti-backfire check valve at the plenum end. Quote Link to comment Share on other sites More sharing options...
