Does anyone use a Wide Band o2 with Alcohol and Nitrous? I am using an EGT meter right now and if it is burning fuel in the header it throws that way off (Which is what I think I have happening). I do not know if using a Wide Band would show a more accurate reading. On motor it shows 1170° of EGT with only 30° timing in the motor usually with low timing it will show too hot like it is lean with that little timing in my case. So When I spray it, it rises to almost 1300° and the motor is fat to just the point of missing on the big end. So I know it is still fat and would like to improve what I have as far as tuning tools if that will help. thanks in advance for advice.
