Autotap o2mv Question? I ran autotap at WOT on the motor and got .920 which is where I want it. When I activate the nitrous (NX wet, bottle at 1000psi) The 02's drop to ".080" (not .800) I have the old DOS Autotap program. The car feels sluggish with the proper jetting (per NX). I know that max reading for the 02's is 1volt (1.00) If your are richer that that, does it go .001 and up on the autotap reading, rather than 1.01? I just realized that since my system was installed, I was only getting 7.5 volts to the solenoids, now I rewired and am getting 12+ volts. Nothing else has changed. Last week it pulled hard, now (since the wiring change) it feels sluggish. I also am getting 62psI at the rail with an additional in-line pump. Could it be that I need to use a smaller fuel jet, and I am getting too much fuel pressure?
