Yeah originally I was going to use use air temp correction. I just wasn't confident it was going to do enough to save engine in the case of meth failure.
I'm not sure how quickly the IAT would react if meth was working, intake temps come down to 30 degrees, all of a sudden, meth dies. Air temp will rise almost instantly (except for latent cooling in manifold etc).
Will the IAT adjustments happen quick enough, or adjust enough to save it? Talking both fuel and ignition. Because remember we have to remove fuel to compensate for the 50% volume of meth. My tables in the other thread show how much fuel we took out of mine up top.
In the end my thoughts were that the table switching was much more flexible tuning wise. Allowing perfect adjustment for both conditions.
Not sure IAT adjustment will allow the same. I'm happy for it to be proven to work well - just not using my engine.
