wtdash Posted December 10, 2005 Share Posted December 10, 2005 Looked around the site but didn't/couldn't find anything specific to this question: What is the the desired voltage on the TPS of the EJ25 in a '97 OB? From a previous vehicle (NOT a Subie) this could be adjusted to .75v to improve throttle response. Link to comment Share on other sites More sharing options...
blitz Posted December 10, 2005 Share Posted December 10, 2005 It's supposed to be set at a half volt plus or minus a tenth for '00 & '02 (sorry no data for '97). The ECU uses this voltage threshold to determine and toggle between idle & part throttle modes (no physical idle switch). There's no performance gains in moving it.
