zedhex Posted September 25, 2011 Share Posted September 25, 2011 Hi All, I am in the process of mapping my emanage ultimate on my Soarer with a 1JZGTE engine. I can get the AFRs ok, but whenever I get close to 1 bar on boost, the injectors spike up to 100% and start oscillating. It looks very strange on the datalog - the injectors go from 66% straight up to 100% within 20ms, and then back to 66%, repeatedly. It looks like a series of jagged spikes on the log. What could it be? Fubar'd injectors? fuel pressure? Any ideas? Quote Link to comment Share on other sites More sharing options...
zedhex Posted September 25, 2011 Author Share Posted September 25, 2011 Replying to my own thread: its the input duty cycle. This is the injector signal the emanage is receiving from the ECU, as soon as it climbs to 100%, the emanage goes nuts and the injectors spike. The solution seems to be to reduce the input duty cycle - but how? Airflow correction? Mods: maybe this should be in non-Supra technical.
