m35stagea Posted November 9, 2016 Share Posted November 9, 2016 (edited) Emanage map sensor woes So im trying to sort out this emanage and I cant get a clean map signal. I have read lots about what others have done on other cars however i am looking for what people have done soecificly on their vq's to rectify this issue. obviously the tune is loading multiple cells and not running properly. Fuel filters Plastic lines Snubbers Mig tips Long hoses.. What has everyone done? black is boost red rpm orange is timing Edited November 9, 2016 by m35stagea Link to comment https://www.sau.com.au/forums/topic/467651-emanage-map-sensor-woes/ Share on other sites More sharing options...
KiwiRS4T Posted November 9, 2016 Share Posted November 9, 2016 What kind of MAP sensor and where and how is it connected? Link to comment https://www.sau.com.au/forums/topic/467651-emanage-map-sensor-woes/#findComment-7790231 Share on other sites More sharing options...

KiwiRS4T Posted November 9, 2016 Share Posted November 9, 2016 You shouldn't T anything into the fuel reg use another source. Link to comment https://www.sau.com.au/forums/topic/467651-emanage-map-sensor-woes/#findComment-7790283 Share on other sites More sharing options...
m35stagea Posted November 9, 2016 Author Share Posted November 9, 2016 You shouldn't T anything into the fuel reg use another source.Thats what i thought however this is the only source that isnt close to the runners or throttle body.

KiwiRS4T Posted November 9, 2016 Share Posted November 9, 2016 Do you have a boost gauge? Link to comment https://www.sau.com.au/forums/topic/467651-emanage-map-sensor-woes/#findComment-7790342 Share on other sites More sharing options...
m35stagea Posted November 9, 2016 Author Share Posted November 9, 2016 Of course. but that doesnt help. The problem is what the ecu is seeing Link to comment https://www.sau.com.au/forums/topic/467651-emanage-map-sensor-woes/#findComment-7790355 Share on other sites More sharing options...

The problem is what the ecu is seeing Um I am suggesting you T your ecu into the boost gauge line rather than the FPR line.

m35stagea Posted November 10, 2016 Author Share Posted November 10, 2016 Um I am suggesting you T your ecu into the boost gauge line rather than the FPR line. Yeah its too clise to the runners and will make the problem worse. Out an 0.8mm welding tip in line and its cleaned it up a bit.

666DAN Posted November 10, 2016 Share Posted November 10, 2016 Looks like noise from voltage oscillation. Have you blown into the tube yourself to make sure the signal is linear?

666DAN Posted November 10, 2016 Share Posted November 10, 2016 Took my feed off the actuator and it didn't flinch. Link to comment https://www.sau.com.au/forums/topic/467651-emanage-map-sensor-woes/#findComment-7790602 Share on other sites More sharing options...

As you can see with the restrictir the signal is alot cleaner now. so it cant be simply a voltage issue.

666DAN Posted November 11, 2016 Share Posted November 11, 2016 On an RB25.....the thing I do notice is your boost spikes when your RPM drops. What sort of boost control are you using?

What sort of boost control are you using? Wastegate. Thats when ecu retards timing to shift gears... dumps fuel. and bang spike.
