TopQ1967 Posted April 21, 2009 Share Posted April 21, 2009 Hi, I have switched my ECU from MBE to DTA. The MAP sensor was in the original instal attached to the bulkhead with no connection to the inlet manifold. Curently the MAP sensor is not connected. As far as I know the MAP sensor should be inbetween the throtle body and engine. What is your opinion? Regards Q. Link to comment Share on other sites More sharing options...
oilyhands Posted April 21, 2009 Share Posted April 21, 2009 Normally MAP sensors are either local and electrically connected to the ECU in whcih case they need to be the engine side of the throttle body, or remote (in or out of the ECU) and connected via a vacuum hose to a point that is the engine side of the throttle body. The MBE as mounted in a Caterham RXXX normally has a remote MAP sensor that does not have a vacuum tube connected to the induction although it is wired to the ECU. In your case it can be ignored and dewired. Oily Link to comment Share on other sites More sharing options...

rj Posted April 21, 2009 Share Posted April 21, 2009 That sensor is not a map sensor although always referred as. It's a barometric pressure sensor, and is used to correct for changes in air density, just like the air temp sensor near the induction. You can live without it as long as you don't drive in mountains or the like, but I would recommend to keep it. Link to comment Share on other sites More sharing options...
Mick Day Posted April 21, 2009 Share Posted April 21, 2009 Depends on the ECU I suppose. My GEMS ECU has a switch for either external (to the ECU) MAP sensor or for internal barametric pressure sensor. Link to comment Share on other sites More sharing options...
