Default SDS CPI2

We've received a lot of emails and PMs here on the new CPI2 so I thought I'd start a fresh thread on that to provide updates.

After all the talk here on alternator failures, over voltage events and LiFePO4 batteries, we spent over a month investigating the best way to ensure power is always available to keep the CPI supplied with power to fire the plugs. We feel we have a good solution now and have been testing that for a couple of weeks, tweaking as we learn more on the bench.

With that mostly sorted, we began preliminary PCB layout about 10 days ago, laying out the rough placement of key components and connectors. Naturally, there are many intertwined aspects which affect each other so all designs are likely to be altered before the prototype stage.

The plan is to be able to control up to 6 coils so the unit can run 12 cylinder engines if desired via the usual waste spark strategy.

We've tried to eliminate all external switches to make for a cleaner, faster installation.

We've done some preliminary studies on the instrument face layout keypad/ display and how to integrate this with the chassis and optional twin PCBs.

So it's coming along but interrupted somewhat as we take care of our regular EM-5/ CPI sales and tech support. We're lining up some new partners overseas to distribute and support the product in other places with high demand and hope to get some OEM deals in place too.

Unfortunately, the product will not be ready for 2017 release as was initially hoped. The keypad vendors usually take at least 30 days to supply product after the design is sent to them. We're not going to rush the product out. It needs to be fully tested to our satisfaction before release.

If all goes well, we hope to finalize face footprint by mid- November.

Thanks to all those who contributed ideas that we could consider and implement into the design. I hope those who are waiting will be satisfied with the design and new features. Please understand that we can't release too many details on all new features due to the competitive nature of this market.

Thanks for your support and interest in the CPI2. I'll update this space as more significant information becomes available.

Have you established a firm price and if so are you prepared to share it?

Too soon to say until the design is more fleshed out. We're a long ways from a prototype and even getting quotes on expensive things like keypads.

Ross: I'm a happy customer of your six cylinder CPI system. Are you going for the Allison and Merlin market here?

Glad you're happy with the present CPI. I suppose the new model could be used on the big V12s. I hadn't considered that. We have some customers converting Jag and BMW V12s for replica fighters who expressed some interest and there is a clean sheet aero V12 being developed down under plus the LS based V12 project.

Not a big market but we'll be ready for growth, potentially being able to run 7 and 9 cylinder radials as well with a dual unit in the future when we have time to write software.
