scoobyscoodle Posted August 24, 2016 Share Posted August 24, 2016 I have a Defi boost gauge in my car hooked up to the MAP reference line off of my BPV. It reads the same boost my car was tuned to(~19psi in S#), so everything mechanically is fine. However, when monitoring boost on my APv3, when I go WOT and hit full boost my max boost value on the AP shoots up to 35-40psi (vacuum as well). Any idea what this could be? Failing MAP sensor? For some reason under partial throttle and boost <10-12psi the AP reads accurately. TD Boost Error is similarly effected. Link to comment Share on other sites More sharing options...
scoobyscoodle Posted August 25, 2016 Author Share Posted August 25, 2016 To make things even more confusing, when I monitor MAP with the AP, it's accurate. I.e., 14.7psi+current boost level. Link to comment Share on other sites More sharing options...
scoobyscoodle Posted August 25, 2016 Author Share Posted August 25, 2016 Well that was easy, firmware update fixed the problem. Link to comment Share on other sites More sharing options...
