Ronny Anderson Posted May 18, 2013 Report Share Posted May 18, 2013 Hello! How do I wire an external map sensor on a g3? Best Regards Quote Link to comment Share on other sites More sharing options...
Simon Posted May 20, 2013 Report Share Posted May 20, 2013 You need to wire the signal from the sensor to a free AN volt input. This input is then selected as MAP, make sure to turn the internal one off. Quote Link to comment Share on other sites More sharing options...
Da'ninja Posted July 7, 2015 Report Share Posted July 7, 2015 is this possible with a lem g3? i cannot see a way to turn the internal one off and select an external one Quote Link to comment Share on other sites More sharing options...
Simon Posted July 7, 2015 Report Share Posted July 7, 2015 On G3 firmware this is not an option on the LEM you have to use the internal sensor. Quote Link to comment Share on other sites More sharing options...
Da'ninja Posted July 7, 2015 Report Share Posted July 7, 2015 On G3 firmware this is not an option on the LEM you have to use the internal sensor. would it be possible if i updated to g4 firmware? currently have a 2.5bar sensor internal but i need at least a 3 bar map as ive built my engine to run up to 2bar boost.

Simon Posted July 8, 2015 Report Share Posted July 8, 2015 Yes with G4 firmware you can. The other option is to upgrade the internal sensor to a 7bar one. Quote Link to comment Share on other sites More sharing options...
Da'ninja Posted July 10, 2015 Report Share Posted July 10, 2015 Yes with G4 firmware you can. The other option is to upgrade the internal sensor to a 7bar one. had a breif look online but cant seem to find anywhere uk based that has internal 7bar sensors, just the external ones. i already have an external 4bar sensor so how much is the g4 firmware upgrade, i will be capable of doing this myself as per the pdf instructions and previous electronic/programming experiance Quote Link to comment Share on other sites More sharing options...

Dave Kriedeman Posted August 15, 2015 Report Share Posted August 15, 2015 Hi gtir,I think that whom ever you spoke with has misunderstood your question.I believe that they must be thinking your asking about upgrading just the G4 firmware.What you need to in fact ask them is the following.You have a G3 and you wish to purchase a G4+ upgrade enable password.This is definitely not free, from then on all of your standard firmware updates are free same as your G3 platform was.Recontact your dealer and ask as I have written.If you still have issue please contact Link in New Zealand.RegardsDave.
