Bullet Starter and USB Cable

Joe shipped the new bullet starter which is real sturdy compared to the original. I have recently tested the beta software ver4 and USB cable for the JJ-Nades FADECs. It is a bunus to download the 50+min of running data and view the running parameters when required on a laptop. This software is available free.

When I spoke with Andy last year he indicated the major return factor was blocking of needles, since the bearing lube injector is very fine and flows at about 50% of an fuel needle, it is interesting that other manufacturers have increased the flow rate to about 200% more flow than a fuel needle. Following discussions on the GTBA site, this allows lower oil content within the fuel and avoids rear bearing problems.

Some will have a JJ as their first turbine, the old jet hands will be familiar with bedding in of bushes and running in their pumps on a loop to filter any fines and rubbings from the gears. Do many JJ owners triple filter their fuel? I use a last filter after the pump just before the turbine. This used to be known problem for the ECUs as any blockage here increased pump pressures and eratic runs. Though obviously if there is no debris this clear filter never collects anything and remains visibly clear.

When problems do occur viewing with a mirror can safely reveal the hot spots as unblocked needles deliver more fuel and blocked needles none. The colour of the burnt fuel and viewing the through the NGV gives a good indication of the mixture burn. As can the chambers residual flame pattern marks.

This has all been covered before in the mags+RCU maybe like teaching granny to suck eggs, just thought I'd mention I still see jet jockeys breathing fumes and looking up the exhaust with terminal possibilities.
