I can't say I've stored pumps for 5 years so can't be sure. They usually have Stoddard Solvent from testing inside which might get gummy over that time period. I see shelf life listed as from 6-85 months.

Does SDS offer a dyno or inflight engine tuning service? I've read the tuning manual a few times now, and I'm not super excited about having to buy and install everything for a wideband o2 sensor that won't be permanently installed. I've done a bit of automotive tuning with HPtuners and Nistune, and even with automotive work, I've come to the conclusion that its faster, cheaper and gives better results to take it to a professional tuner with the right equipment. I know it'll fly just fine with some basic adjustments on the stock engine/ignition map, but after its been flying for a bit, can I bring it up to Canada or one of your US distributors for a tuning session?

We've got maps for most popular engines but there are always subtle differences between each engine and exhaust system differences can change things a bit more beyond that. At the present time, with leaded avgas, there isn't a good way to implement reliable closed loop control which we'll be able to do in the future when unleaded avgas arrives.

If you send us a data log file by email, we can usually make some mapping suggestions or help diagnose an issue.

Lycomings are pretty tough beasts compared to automotive engines and tolerate a very wide range of AFRs with little complaint. The main issues we see are high CHTs in the climb and most of these are addressed with retarded timing and extra fuel in those areas

We don't do work on other people's planes for liability reasons and we wouldn't have time in any case due to the order backlog we currently have.

There may be some shops in the US which would take this on although the ones I am thinking of are mainly builder assist shops working on client aircraft with SDS installed.

Production Booked Through to Jan. 2022
 
As of today, we're booked with orders of EM-5 and CPI-2 systems through to approximately Jan. 15/22.

CPI and CNC'd billet parts can usually be sent out within 14-21 days, depending on stock or production run status if not in stock.

We have a few delays caused by suppliers so have had to massively stockpile numerous components which have unsteady/ uncertain supply now. We've had to switch vendors in some cases unfortunately.

Thank you to everyone for your orders. :)

We've had an amazing sales year so far in 2021, so much so that unfortunately we'll run out of EM-5 ECU boards before the end of this month. PCBs were delivered late for the next production run and sales were much higher than projected leading to a gap in supply. The next board run is in process now and we expect to have the finished boards in hand in the latter half of Dec.

We've also experienced some delays in sourcing and receiving certain chips and other kit components though our early anticipation and overstocking of most of these items have mitigated a good portion of this.

In the meantime we'll continue to build the rest of the systems as usual, minus ECUs so delivery delays can be minimized.

CPI, CPI-2 and CNC'd parts orders are not impacted by this.

Kit deliveries are now booking out into Feb. 2022.

On the EM-6 ECU front, good progress is being made with the on board memory and reflash features. This part has been very time consuming. If things continue to progress smoothly, we anticipate PCB design to commence in Q1 2022 and testing in early Q2. Finally the end appears to be in sight (how many times have I said that now?). We have dedicated, on average, 2 days per week to this R&D process in 2021 and that has slowed deliveries somewhat but was the only way we'd ever get it done given the sales volume.

On the machining front, Trevor and Howard have added more 4 and 5 axis capability and higher spindle speed machines and new fixturing to increase production and try to keep costs down (outside of material price increases of course). These allow a single load and setup cycle to run more parts.

Thank you for your continued support and orders. We are looking forward to producing new and improved items for your RV projects.

We were just informed that our run of ECU boards will be delayed until mid January at the chip loading facility unfortunately which will delay some system deliveries a bit more.

We'll keep building kit orders to minimize delays when the ECU boards arrive.
