We took the plane up today to look at "lean of peak" performance for our non-Gami Injector motor. I would really like some input from those of you out there that have experience with upgrading to Gami injectors and want to consider if that is a worthy upgrade. The Surefly Electronic ignition is also on the table as our motor has separately driven magnetos.

You can see in the photo of the EDM 930 that we achieved a gami spread of .7 gallons/hr between cylinders 1 (richest) and 2 (leanest). The GAMI website states that a spread of .5 Gph or less is a relatively well-balanced motor. I'm looking forward to any experience you all can offer. The debate is over putting dollars toward this at next annual, or moving toward electronic ignition first.

Thanks in advance for your input.

Paul
