Would you say that an egt is a better way to gauge the mixture than an oxygen sensor. Reason I ask is I will be running a power grid system and msd just released a new dual channel ntk type oxygen sensor kit for there grid. They claim the ntk sensor are much more accurate with alcohol fuel and that alcohol ruins the Bosch style sensor. The kit is pricey though. I hVe lots of friends wanting to go fuel injection. I want to stay carburetion cause I can fix it lol.
