SDS EFI in 2023

[rv6ejguy]

At this time we've sold out of CPI-2 main circuit boards. Due to our large order backlog on our other products and trying to finish off the EM-6 we've decided to stay CPI-2 production until at least the third quarter of this year or whenever we have time to deal with it again.

Have to concentrate our main energies on filling present orders and getting on with the EM-6.

Existing CPI-2 orders will be filled of course.

Lots of CPIs in stock. Those orders can be filled in around 30 days generally.

EM-5 orders stretch out into March now.

As we get closer to EM-6 rollout, I'll be posting some updates in the coming weeks.

One thing to note for new builds and those who'll be upgrading from EM-5 to EM-6 ECUs in the future- if you want the SD card logging feature, you'll need to make provision for a breakered or fused 2 amp 12V wire to feed the external SD box.

This box is about 3 X 2.4 X 0.75" and can be mounted at the edge of the panel, underneath, in the panel or in a place that is easy to reach to extract and insert the card. There are 2 status LEDs to the right of the card slot.

Data and power connections at the rear.

I'll have some face and hole spacing dimensions when it's finalized.

This is the prototype to give you an idea of the shape.

I've had a couple good PIREPs from SDS customers using the Monkworkz generator system. This seems like a good lightweight way to go for backup power.

Check them out if you're contemplating what to do in this regard.

Thank you, Ross! I will look into them.

Hey Ross, I have a question about tuning. We've got an exhaust pop during descent if we do them at <75% throttle. It's a rich pop because it goes away if we turn the knob significantly lean. With the way the MAP and RPM tables are implemented, is there a way to lean the mixture below 75% throttle only above 2300 rpm? We use the same throttle settings in the pattern, but are normally off the governor by that point so the rpms are in the high teens or low 2000s and we don't have any issues with popping once we've slowed down and come down on the rpms.

Our current work around is to just leave the LOP button active until we reach pattern altitude. We like to disable LOP as step 1 in our descent checklist though, so if ATC has us stop the descent or we need to add power for maneuvering it's already taken care of.

We've seen this a few times. Usually taken care of by leaning the MAP fuel values below the idle range which is 8-10 inches.

You can try reducing the MAP values from 8.05 to 4.59 by 20-25% as a first try. Don't touch the values below 4.59 as they are defaults in case of low MAP sensor failure, the ECU will fuel high to allow high power when throttle is advanced.

We'll give it a shot. Thanks.

Several folks are at the panel planning stage and have been waiting for dimensions on the SD box. Box will be black anodized with white laser etched lettering. You need a breakered 2 amp circuit to power the logger. Can be mounted from behind the panel (through) or under the edge of the lower panel flange.

Here they are:

Any estimate of the final weight of the individual items including this?

Would need to know: engine model, single or dual ECU, vertical or horizontal induction, coil mounting, fuel block preference.
