big-phil Posted March 28, 2007 Share Posted March 28, 2007 It reads REAL close, but not exact. The PLX guage might read 11.5, and in megatune it reads 11.8 or so. Its real close, but not spot on? In megatune I've got the voltage set to 4.998v, starts reading at 200rpm. mind you I have not driven it, just idle in the driveway. Quote Link to comment Share on other sites More sharing options...

Matt Cramer Posted March 30, 2007 Share Posted March 30, 2007 First, check to be sure they're grounded to the same point. A ground offset can make a wideband read a little bit higher or lower than it should. Quote Link to comment Share on other sites More sharing options...
