Extreme makeover 72 seafari 25 aloha edition

[Xcomunic8d]

Thanks for the idea bushwhacker. I’m into planes once upon a time was going to be a pilot. Then got glasses…I ended up in secure logistics for over a decade.

I’m familiar with Lycoming and Pratt and Whitney. I suppose I could rig a vac gauge instead of the Hobbs meter. Wonder if the Terminator x has that in the handheld. There is the KPa. Doesn’t seem like the map KPa conversion to InHG is equivalent to your specs. A gauge may be only option. I’ve never heard of it on I/O but we use them plenty to diagnose engine health.

Got to research this more. Along with my heat exchanger issue. That has me frustrated.
