Engine monitor choices
I'm thinking of a few possible upgrades for my 1970 Cherokee 180. An auto pilot would be cool, but might rank behind a good engine monitor, so, what do you like to use? I am becoming something of a fan of Mike Busch and his methods after just reading his new book called ENGINES. My 0-360 A4A carbureted engine runs great and has 1650 or so hours SMOH. Considering the regular use it has always had. It got two new cylinders a year ago including a peek at the still very good cam. Per logs it has had a steady diet of 25 hr oil changes with cam guard, I think I can go WAY past TBO on this engine. My theory is that a good engine monitor can help me do that.
What do you have and like for engine monitors that I should know about? I assume I will want the recording data ability. Fuel flow, percent power, and a few other features look like fun, but I'm not sure I need that. A whole primary replacement system that eliminate the factory gauges is likely more money than I would be willing to spend unless there is a REAL good reason and a sale price. Current thinking has me hovering around the JPI 730-830 types of units, but I am not married to any particular unit.
