dr z Posted April 18, 2012 Share Posted April 18, 2012 i would ask to hr owners if they know the existence of ecu firmware upgrade. 'cause three hr z found problems after cleaning throttle body (without move throttle valve). The problems is idle up and down and irregularity at low rpm. no results with reset no results with uprev no results with consult 3 my tuner (uprev dealer) after many attemps obteined a stable idle but our z is not straight. before stopping the car the rpm rise to 3000 and then down to 1100 when the car is arrest. when shift up at low rpm the rpm rise to 3000, like you forgot to leave clutch pedal the problem may be located in the ecu not updated. let me know sorry for my english thanks Quote Link to comment Share on other sites More sharing options...

marzman Posted April 18, 2012 Share Posted April 18, 2012 Have you done all of the necessary resets? Having just had a quick search it sounds like there are a number of resets that are required: ECU reset Throttle position reset throttle body reset idle reset I think the guides for each are here: viewtopic.php?f=35&t=55272 (see search results here: search.php?keywords=throttle+AND+body+AND+idle&terms=all&author=&sc=1&sf=all&sk=t&sd=d&sr=topics&st=0&ch=300&t=0&submit=Search) Quote Link to comment Share on other sites More sharing options...
