i.e. after calculating and pasting the IFR table, if you think it's running 5% lean, then add 5 or 6% (say) to the VE table instead of 15% as said in the Auto VE tutorial.
Ok think I found the misfire issues. Pulled one of the plugs that was reporting and it's as black as black can be. I'll get a new set on the way. with the new IFR calcs I shouldnt have an issue. It must have been so rich it just did em in. Car only has about 70-100 miles on it since all the latest mods.

changed them and re-flashed new IFR and same thing as far as the misfires 6,7 and 8. I'm about to shoot myself now. I'll post the log as soon as I get back. 2 hrs

TOL (Thinking Out Loud)
If the cylinder misfire counts overflow, then the cylinder misfire history gets bumped (and this history bump may in turn flash the MIL)...
So if it doesn't go above 40 and it periodically resets itself back to zero, then it may be ok... (I said "may").
The coil pack subharness is all ok back there (no rubbing/chaffing)...?
Hmmm... misfire could also be due to running lean... (injectors may be spraying less... is it possible for the rear injectors on each back to spray less...?)... or, do you think you're still running too rich...?
Why those 3 cylinders...? I have read about the rear injector screens copping junk from the fuel rails, which supposedly the factory F-body rails are said to be able to rust internally...I don't know if you have aftermarket rails... it's too much work to pull the injectors only to find they're ok...
I can't view your log until I get home tonite.

I dont think its lean, as soon as you see the log you might agree. I cna pull the rails it's not a huge job. The first log I only had a few and then I had them everywhere and always the same count for each cylinder same as now.
I think I need to set the 6% instead of 15% as well

EXT.AD2 hovers around 2.5V which leads me to think either it's not coming ready (may have a broken sensor)... does the LED flash for 20 sec and then go on steady...?
Before you pull the injectors/rails, do the injector balance test from the scantool: Bidirectional->Cylinder Balance Test
If cyls # 6, 7, 8 produce different results than the other 5 cyls, then they would be the problem.
BTW: your SPARKADV shows negative... if you V1 BB logged, enter your VIN/OS and reprogram the BB.
What LED?
I've been logging using my laptop
I pulled a couple plugs to look at them and they were black again. They cleaned off easily though.

Don't you have the LED/pushbutton wired across the black and white wires on your LC-1's...?
The pushbutton is for doing free air cal, the LED is for observing the state of the LC-1 (coming ready, ready, or flashing error code).
