I didn’t get much time today to work on the plane, as we had a BBQ to go to for lunch. Once we were done there, I went to the hangar to work on the FADEC stuff.

First off, I clocked the fuel distribution block around 30 degrees to see if it would help with the cable lengths. It does, but it also causes another problem. These senders are so long that the rearmost one’s cables will interfere with the rear baffle. Hmmm. I’ve decided to buy some 45 degree fittings to reposition the fuel pressure senders. That should help a lot.

Once that was done, I set about putting the reinforcement angle behind the firewall for the ECU’s. This was a pretty easy task. I decided to mave up the lower ECU a bit to be 100% sure about clearance to the fuel pump outlet. The bottom of the ECU mounting plate is now in line with the bottom of the firewall recess. This looks like it’ll work out pretty nicely. Here’s everything mounted. I need to order some holy head bolts for the ECU mounting so I can safety wire it all.

Here’s the lower ECU showing clearance to the fuel pump outlet. I’m much happier about it now.

And the angle behind the firewall.

Clearance for the prop control cable.

That was about all I got done. I puttered about a bit cleaning up, and then went home.
