Jim Papageorgiou Posted October 3, 2010 Report Share Posted October 3, 2010 I own a Link G4 Storm till yesterday i was using the 'onboard' map sensor without any reasons the map stopped working... i didnt do anything at all...my car just not running.. is there any suggestion first of all why the map stopped working?

seized Posted October 5, 2010 Report Share Posted October 5, 2010 Checked the easy things like the hose being split open or kinked? Any sign of fluids in the hose? Quote Link to comment Share on other sites More sharing options...
Jurgen Biggelaar Posted October 14, 2010 Report Share Posted October 14, 2010 Hi Jim. Is it reading 100 odd KPA at rest... ie. making sense there? Does the MAP reading move at all when trying to operate the engine. What is the lowest vacuum it is seeing? Press the F12 key and see the figures exactly under the Analogue tab/Analogue data. You can also see the voltages in the other window on the same tab. Jurgen Quote Link to comment Share on other sites More sharing options...
Jim Papageorgiou Posted November 2, 2010 Author Report Share Posted November 2, 2010 noop the map always reads 100KPA... it doesnt move at all...either at vacuum either at pressure...always it reads 100KPA... to say the truth i didnt try the hint with the F12 key...i will see it and i will inform you right away...

Rod Smart Posted November 5, 2010 Report Share Posted November 5, 2010 There is a verification test you can try, tho there may not be a problem here.. Disconnect the vacuum hose from the ECU, and while the engine is running, and viewing the laptop, put finger on end of vacuum hose, see if your finger sticks there (verifies there is vacuum at ECU end. another thing to try, place a separate hose on the ECU (can be done with engine stopped, but ECU powered on) and suck the other end of that hose and notice the results (best done with new hose, 1/. it should be clear inside & 2/. no taste of oils/dirt on end of tube that you put near mouth Quote Link to comment Share on other sites More sharing options...
Jurgen Biggelaar Posted November 18, 2010 Report Share Posted November 18, 2010 Here's some data to add to the list that may help. 1. Internal MAP sits on AN Volt 5. 2. 2 MAP 'functions' cannot exist on the same tuning map. If you want to run 2 MAP sensors on the same tuned map, one of them will have to be tagged as either a 'Voltage 0-5v' input, or GP Input with a CAL, not MAP as the ECU will not know what 'MAP' tag to use. 3. Key on, engine off the internal MAP sensor should read approximately 1.8v. 4. As rod says, suck on a hose attached to the internal sensor (preferably with a mighty vac or similar tool), and just see if it at least registers (taking in to consideration 1. & 2.) 5. For me, please do number 4. if possible, and pump up as well as vac and get back to me with the results. I want to see if the internal one is making sence. Does it have a GOOD span from 0-5v? TIP: Using F12 and going to Analogue/Analogue data... Will show you the voltage instead of the Kpa on AN Volt 5 for the internal map.

Jim Papageorgiou Posted March 17, 2011 Author Report Share Posted March 17, 2011 Ok that kind of fault was recovered after the latest firmware update... Thanks a lot for the info.. I think that previous firmware wasnt placed well when done it.. thanks again!!! Quote Link to comment Share on other sites More sharing options...
