H22J03Y Posted June 9, 2010 Share Posted June 9, 2010 i moved to big bear california. it is 6800 ft above sea level. when i go down the mountain my vtec works. when im almost up id say about 6500 ft up my vtec will no longer work. im running a p28 with hondata s100. my shop told me its because of the barometric switch. they said it reads the elevation level and when it goes up to high it shuts down the oil lines for vtec. does anyone know if this is true? or have any other idea what could be causing my vtec to stop working. I really want my vtec to work up here. any ideas how to fix it? Link to comment Share on other sites More sharing options...

Northstar Posted June 14, 2010 Share Posted June 14, 2010 This was already posted in another section. h22 vtec problem.barometric switch.need help I don't know why he posted it twice. Anyways, Misterspock is correct. The only way to recoup the power lost during high altitude operations with a piston engine is through forced induction.
