Default ATAP and Nitrous

Just got autotap and have a few questions about it.....maybe ya'll can give me a little insight...

I changed up my nitrous setup to the new NX MAF kit. To make sure that everything is working properly (basically, not running too lean or too rich) which parameters should I be looking at on the ATAP system??? I just want to be absolutely sure that everything is in proper working order before I go back to the track to make a few passes on the juice....


Thanks a bunch,
Conrad

You want to look at the O2 millivolts and Ignition Knock retard.

Ltrims should be running at about 0 at idle.

O2's at WOT should be in the .910+. Yes it is on the rich side, but it is better to be safe than sorry.

Knock retard should be 0 (or as close to 0 as possible). Now that it is hot out, running 93 octane, I did have a 2.8 knock. I am hoping with the newly aquired 104 octane this will go away.
