Gami injectors on IO-550

Unread postby gear » Thu Aug 20, 2015 9:20 pm

Just curious to know if anyone is running an IO550 on this forum with Gami injectors? I am new to the 550 this year and new to fuel injection and i recently installed the Gami injectors. When you purchase them, you submit your "Gami spread" and then they give you their matched injectors. I did that and started with a 1.5 gom spread and ended up with 1.2. They say they would like me to get .5 gph spread or less. My cylinder1 and 2 were still a little rich and so they are sending me new injectors for those cylinders.

Just wondering if anyone else has experience like this on this engine?


Thx.

Most Air-Taxi operations are too cheap too invest in the Gami Injectors. I know that Continental and Lycoming have indorsed the use of Gami Injectors and have improved their OEM injectors because of Gami's results.

Many pilots like to improve their fuel economy by leaning Lean Of Peak (LOP). I don't like engines operated LOP because each cylinder is a different lean or rich mixture. If you're running Gami's the engine will not suffer as much from the problems that stem from LOP.

I had them on my Bonanza and they worked great. I could even run LOP but I preferred to go fast.

I can get to 100 F lean of peak on some cylinders although at that point, I'm running way too much excess air and hence temperatures that are actually too cool for lead scavenging (I'm told)

Well - I received 3 new injectors today. Doing some fine tuning on the cylinders. According to GAMI, I should really tighten up my temps after I get these installed.
