The CPI2 has better over voltage protection, backup battery solution with auto switchover and warning, more programmable settings, serial output for data logging is available.

With the remote mounted controllers, the panel space for the programmer is much reduced, especially when dual controllers are used. (single programmer can talk to dual controllers). The panel LCD is larger (12 X 2 characters).

Downsides are costs are substantially higher but still in line with other EI choices which aren't easily user programmable and have less capability. Weight and total volume is higher on the CPI2.

As I said previously, we plan to produce both since there is still good demand for the CPI as it's light, compact, capable and relatively inexpensive. Not everyone wants or needs all the new features in the CPI2.

I started on a new CPI2 webpage 3 weeks ago which will outline all the new capabilities and but don't want to upload it until all testing of the production parts are completed successfully. I don't subscribe to releasing glowing reviews of vaporware before the product exists and has substantial testing behind it. This thread covered some of the difficulties faced during development and the solutions found. We don't sugar coat things- this was a very challenging product to develop.

Glad you're sticking with both products... The original CPI is an outstanding system, forgetting for a moment its the lowest price EI option out there.

How do I get added to the waiting list?

I'm not sure about a single or dual setup, but I most certainly want a CPI-2 system.

If you drop me an email, which you can find by clicking on either signature link, I'll add you on.

Thank you!

Default Thermal Imaging Tests

We completed the IR imaging tests on the production CPI-2 board today and all concerns from the prototype boards have be rectified. Nothing gets over 50C.



Controller running coils at 6000 rpm. The thru hole regulator is now heat sunk to the chassis and runs nice and cool as opposed to the SMT component we first tried.



6 cylinder coil pack running at 6000 rpm. Center of coil pack and spark plugs (upper part of photo) show the highest temps.



This one was just for fun

We ran the system up to 11,000 rpm for 20 minutes. This is about the limit for things staying adequately cool. Nothing even gets warm at 2700 rpm. Barry added back a bunch of ozone to the atmosphere with all this bench running...

We are adding a few more features in software now which we thought would be nice. Engine tests will be coming soon.

This photo shows the CPI-2 programmer in gauge mode with the fault light illuminated, LOP mode activated (adding timing to bring peak cylinder pressure to the optimal point with the slower burning mixture), running off the main battery source and programmer is accessing controller 'A' CPU.

The weather turned cold and snowy this week meaning we couldn't run the system on our test engine so Barry cleaned up and tested the data logging software instead. This will log data to a laptop or Windows tablet for diagnostics or tuning. He also did some final testing on the OV protection features.

We had our contractor girl working on programmers and controller boards this week and we've inventoried coils, drivers, sensors, connectors, CNC'd parts and other bits to build complete kits for those on our waiting list.

Default Data Logging

Here's a shot of the data logging screen in the gauge mode.



You can save and print your ignition maps from here too.
