I t hink I could get my cruise fuel flow down to about 10 gal/ hr if I got my in jectors tuned better. Time will tell. I used real brake lines made up by All Hoses just down the street. I thought the Vans supplied hoses were junk. A friend of mine has a custom brake flu id reservoir with a float switch in it. If I can get him to build me one I a m going to hook it up to a general purpose wire on the EMS and build an icon for the Dynon EMS screen to display low brake fluid. I use my middle screen to display engine instruments at 100% in normal mode t he numbers on a lot of instruments were awfully small and I got a friend of m ine to modify the file to increase the size of the numbers on a few of them.

I think I will try that first. Barrett matched the injectors to all flow the same, so that may not do any good. It depends on how close they are. The other part of the equation is airflow.

I would expect they probably flow matched the cylinders as well. I would inspect and clean the #2 injector, then swap it with the #4 injector. That will tell you whether it is the injector or something else. If #4 becomes lean you know it is that injector. If #2 remains lean then either one of the lifters on that cylinder is not operating to spec, or there is an air leak somewhere.
