Running a WAI through the wringer

[FrugalFloyd]

Thanks. Yes, I can monitor ignition timing. It varies when I'm DWLing. If I try to keep it in the high 30s, my mpg will be the best - often in the 50+ mpg range and higher. But I lose speed most of the time maintaining maximum ignition numbers. Cruise control, which I used for today's testing, often drops ignition values into the teens.

I was monitoring FWT, FIA, LOD, and current trip fuel economy. If I monitored ignition, I'm not sure how to use that information in real world driving.

I'd like to know how to get my IATs higher. I'm drawing air from over the exhaust manifold now. I'd have to seal the engine compartment, causing all sorts of unintended consequences, like melting rubber and plastic parts, causing the cooling fan to run all the time, etc.
