Default Rusty Crawford's RV7A with SDS EFI



This is Rusty Crawford's beautiful RV7A from Friendswood, TX just after he painted it.

Rusty is one of our highest time EFI customers, having started out with Subaru power originally, migrating to Lycoming power a few years back and now upgraded to a full dual EM-5 system. I believe he's approaching 1700 hours now with EFI. He's been extremely helpful in giving us feedback, new ideas, testing and helping other SDS customers in the Friendswood area.

Rusty is an all around, super talented, super friendly guy. Happy to be associated with him and to see his airplane painted in this gorgeous paint scheme. Nice work!

Ross,

Beautiful airplane!

Can you tell us about the electrical architecture Rusty uses? Things like, how many batteries, alternators, buses...

Is he using the dual channel EM5?

As I understand it from a recent communication, the EM5 also drives the electronic ignition eliminating the need for the CPI. Is that correct?

We used to live across the runway from Rusty - great guy, a d a real "motor-head" - an excellent person to be giving feedback on engine stuff. Glad he's giving you feedback Ross - a perfect guy to be putting on the hours.

I got to know Rusty when I was working in Houston a few years back and everything said about him is spot on.

Hopefully Rusty will pipe up on the electrical system layout when he gets some time.

Yes, he's using the dual EM-5 ECU setup. The EM-5 can do both EFI and ignition control together. On the 4 cylinder, dual setup, each ECU has its own crank and MAP sensor and runs one set of plugs. We can switch injector control between either ECU.

Thanks Ross.

When using the dual EM-5 configuration can just one SDS LCD Programmer be used or wold two be required in that situation.

A dual programmer is available. Single control head; controls both boards.

As Toobuilder said, SDS offers a special programmer (single unit) which can access both ECU boards with the flick of a toggle switch. No need to unplug cables and switch between ECUs, which is a pain. This also allows the 6 cylinder folks with the individual fuel trim option to trim cylinders 1,2,3 on the primary and 4,5, 6 on the backup as they share tasks when in the Normal mode.
