stevefh Posted June 8, 2019 Report Share Posted June 8, 2019 Hi all, first ignition on engine not running,of the day ,freescan shows baro 0.84 Map 0.9. Is there a problem with the map sensor? Quote Link to comment Share on other sites More sharing options...
fjmuurling Posted June 9, 2019 Report Share Posted June 9, 2019 Use espritmon. The conversions in freescan for baro and map are wrong. Quote Esprit Freak Link to comment Share on other sites More sharing options...
stevefh Posted June 9, 2019 Author Report Share Posted June 9, 2019 Thanks Freek, accepting the fact they are wrong ,should they still be the same? Quote Link to comment Share on other sites More sharing options...
fjmuurling Posted June 10, 2019 Report Share Posted June 10, 2019 with the right conversions they should be (almost due to tolerances etc) the same. The freescan values you posted look correct, ie no problem with the sensors. You can double check with the espritmon software, it will give you the right (correct conversions) values.

stevefh Posted August 9, 2019 Author Report Share Posted August 9, 2019 Hi all, as I said before Baro showing 0.840 and Map showing 0.900 as Freek said this is close enough using Freescan,I have not got Espritmon. On the Freescan sensor diagnostics screen it says in “bar “and above the column “scaled”,I have tried but I have no idea how atmospheric pressure gives 0.84 and 2.24 equates to 1.1bar. My actual problem is that ,ignition on, engine stopped,first thing in the morning when the map and baro should both be recording the same atmospheric pressure .According to various EMH manual sources when reading the same pressure, the baro volts should read twice the map volts.My baro reads 2.25 volts and my map 2.35 volts from the Freescan diagnostics screen.Have I a problem or is that screen information incorrect in Freescan.Thanks for any help.

Chillidoggy Posted August 9, 2019 Report Share Posted August 9, 2019 http://tudl0493.home.xs4all.nl/ Espritmon should be available there. Try downloading that first. Quote Margate Exotics. Link to comment Share on other sites More sharing options...
sailorbob Posted August 9, 2019 Report Share Posted August 9, 2019 The EMH manual is incorrect, the conversion to volts is the same for both the BP and MAP sensors. Quote Link to comment Share on other sites More sharing options...
