Load the config I sent you into your scanner. Connect the scanner to your car with your engine off and the key in the run position. Hit the spacebar after your are connected and let the scanner load all the parameters. Now close the connection and discard the log it just recorded. You should now be able to insert a 3 Bar PID in your table display. Search through the entire list it will be in there and delete any other non 3 bar map sensor PID's you have in the table display.
Now setup your custom wideband PID's and your AFR error % PID. Go to histograms and select histogram settings which is to the right of #12. Select #7 and where it says PID click that and insert your User defined AFR error % PID. Do the same for #8 and make sure when you exit out you commit the changes.
Here is a video you should watch on using the copy / paste autotune features http://www.thetuningdoctor.com/HPTun.../copypaste.swf

You REALLY, need to gap those plugs, thats VERY important on any power adder setup. How much boost is it making?

Just PM me your e-mail and I'll send you my 3 bar config, I run a FAST MAP sensor also. I have some custom histograms you might like, & a Boost PID that I know you'll like. The only thing you might wanna do is delete my fuel pressure PID that I log & change the wideband out, I use an Innovate LM1.

BR7EF's come gapped around .022-.024" from the factory. The AFR error % function is
100*((([PID.2811]/.5)+10)-[SENS.121])/[SENS.121]
Which is what I posted earlier. If you're talking about the histogram filter for #7 and 8 those were already setup in the config I sent. Those were to only collect data above 2% tps on #7 and below 2% tps on #8. [SENS.90]>2% and [SENS.90]<2%

I would never trust the gap on a plug right out of the box, its free insurance to check them first. I'd also double check the plug number, have a friend with an outlaw drag radial car, we were changing the plugs before a race & we found 1 plug to be packaged wrong. It was 1 heat range hotter but the box had the correct # on it. He only knew to look for it because the same thing happened to a friend and it cost him a motor.

im switching to an 8 plug instead of my br7efs i think this may have something to do with a little of the knock as well. i forgot the NGK #8 plug that i use to run. Anyone have a part number?

my only concern is the tip is protruted (sp?) it comes out and you actually see the porcelain. but on the BR7EF its inside, which i heard is safer for n20/boost :/

The way your knock sensors go off appears you have some wiring issues or bad knock sensors. I noticed in one of your other logs you were getting 4 degrees of knock @ part throttle with out any boost. When they always pull the max timing it means something is up and the uniform blocks confirm that.
