JPI 830 w or w/o Gami's

[PT20J]

Getting rid of the old factory gauges was the reason I added EIS to the G3X. I spent a month tracking down and making an owner produced part to replace a no longer available failed Kulite fuel pressure transducer and was concerned about the B&D tach going south some day.

Very interesting. I never knew that. GAMI injectors were about halfway down on my capital improvement list.

While I will not say that Gami’s are a gimmick, that’s sacrilegious on this site and there will be hordes with torches and pitchforks.

I will say on the two airplanes that I installed Gami’s on, an IO-540 and an IO-520 that fine wire tempests made more difference than Gami’s did, and that was two engines that most say “need” Gami’s.

My Gann “performance” IO-360 engine is the poster child for LOP, I swear you could land the airplane with mixture it runs so smooth at extreme lean mixtures. and doesn’t have Gami injectors.

However if for whatever reason you need to replace stock injectors, I believe Gami’s are less expensive and are as good as OEM from what I have seen.

I do not have Gami’s nor do I have an engine monitor and most of my cruising is done LOP. You don’t need either to safely run LOP, just never try LOP at high power settings and you will be fine.

Usually LOP is done to reduce fuel consumption, and another way to reduce fuel consumption is of course to slow down, so the way to reduce fuel consumption the most is to do both.

I climb to cruise altitude which for me is usually between 3 and 8 thousand or so, reduce to 22 squared and lean to 7 GPH, at that low power you can’t hurt the motor no matter what you do with mixture, and that gives me just under 130 kt cruise, which is fast enough for me, and is very economical.

Spending thousands on equipment to save a few dollars on fuel from an economy perspective just doesn’t make sense to me, and you don’t have to, to run LOP, just be conservative and everything will be fine.

I will eventually replace my probably tachometer with the EI CGI -30 as I have no space in my panel for anything, and I have a lot of experience with the EI folks, and their product support is second to none, not saying anything bad about anyone else, just applauding EI for their support.
