NTK sensors tollerate lead much better than the bosch sensors from what Ive been told. They are much more expensive though...

We run NTK sensors with C-23 race fuel and obviously have a two step. The current sensors are on their second season. They are about $180 a pop

you waste your time reading a plug that been idled. Here is what i recommend to the OP.. I take two extra (used) plugs and the socket wrench in the car with me when i make a pass and need to check plugs.. click it off after the stripe.. coast off the track pop the hood. and pull a plug from #1 and #7. replace with the used plugs. drive back to pits and read the plugs in your hand. tune accordingly. then install two fresh plugs in 1 and 7 make a new pass..and repeat. a box of 8 plugs will get you four passes to tune on..instead of using 24 new plugs in every hole..for the same 4 passes.. when you get it where you think its working...then i pull all 8 at the end of the track to make sure all 8 are happy...
why do people make things so complicated...
i read somewhere.?you can soak the 02 sensors to make them work again..cant remember what the stuff is called that you soak it in.... ive never done it..

Just out of curiosity, why 1 and 7? I know they are on far ends of the block, but on the same bank? Good info though - thanks.
I think he is pulling the 2 easiest plugs(for him)

What wideband set up did you go with? For carb tuning I always liked the lm1 with rpm converter, and added a narrowband sensor/ map sensor in the aux inputs. This gives you load, rpm, actual a/f ratio, and happiness a/f ratio. Very usefull info...

Finally got a chance to run a few WOT tests today and I was getting wide band readings in the 10.5 to 10.7 range @ 6200 and 15 lbs boost. Keep in mind I am testing with a full exhaust and 5000 feet above sea level. Still way fat - I would think? I will try going back to original jetting ( as I got the carb from Pro Systems ) and see if that will lean it up a bit. Pretty sure that is where my short plug longevity problem is coming from also. - - lead fouled.
