The LOP button is designed to be used when you lean the engine to LOP. This advances the timing (usually 3-5 degrees) and picks up some of the power lost when running lean of peak due to the slower burn rate of the mixture.

Usually see 3-6 knots come back over fixed mag timing, depending on airframe and how far LOP you are.

The amount of advance for LOP is user programmable as are the basic RPM and MAP timing curves. In fact, almost every parameter right down to cranking retard and coil charge times can be changed.

This is the "Last Word" in aircraft EI systems where you want full control of your timing and not a canned curve like most other EIs offer.

Lets say I have a 180 hp Lycoming IO-360 with Bendix RSA fuel injection. The injectors are balanced, and I install your CPI-2 product to replace both Mags. Cruising at 8000' at 60% power and have the timing set lets say to 25 BTDC. What about 10,000' or 12,000'?

I'm guessing EGT decline, CHT's rise.....will I see airspeed rise too? How much?
If you are in fact cruising at 25 degrees advance as your baseline, then activating the LOP feature will show you 5+ knots increase in speed, a 5-10 increase in CHT (which will help, because you will be too cold), and a reduction in EGT.

This assumes that you took the 10 minutes to find "your" optimized LOP value for that condition (EGT/altitude).

We'll have finally cleared our order backlog for CPI-2s by tomorrow so things should return to "normal" around here. This means more time to devote to the EM-6 project which has been coming along steadily but not as fast as we hoped, due to time spent on building and shipping systems. This also means I'll finally have time to get back to other development projects which have been delayed this summer.

We can deliver CPIs in one day, CPI-2s in 2 days and EM-5s in about 3-4 days with our usual backlogs. 6 cylinder versions are available now if you're tired of waiting for other brands to be supplied.

Thanks to those who've ordered CPI-2s to upgrade from CPIs- we didn't expect much of that.

Default Temperature Testing Video

I posted a new video on temperature testing of the CPI-2 controller today:

Default Dual Mag Engines

We have some new parts now to be able to remove the much hated Dual Mag setups and replace with SDS EI units.

The new parts allow mounting of one of our 4 or 6 cylinder coil packs where the mag unit used to be. The 2nd coil pack could be firewall or engine mount tube mounted. This would be applicable to SDS CPI, CPI-2 or EM-5 systems.



4 cylinder



6 cylinder

Do you make those littlemagneto clamp blocks too? I think I'm going going to need a couple...

We have 2 different clamp styles depending on stud length and thickness of cover plate flange. These are 7075-T6 and designed to be used with no gasket- RTV only.

Default RV-3B CPI-2 install

I posted a couple photos of Mike Kellems' CPI-2 install on his RV-3B. He's been running CPIs for a while now and decided he wanted the newer system on there. Not much space on these aircraft but he's getting it done.

Photos are down near the bottom of the page: http://www.sdsefi.com/cpi2.htm

Good stuff Mike and thanks for the photos as always.

Thanks Mike. Flickr isn't the easiest thing to figure out and you'll have to trim the link afterwards.

Click your photo on Flickr
Click curved arrow bottom right
Upper right, choose BBcode
Right click the link to copy code
Click on VAF insert photo icon
Backspace the HTTP to get rid of it
Right click in the empty box to paste your link
Delete [IMG] on both ends of the code
Delete everything behind [/url]
Delete the photo file name just in front of [/url]
Check if it appears right in the VAF post by clicking preview before posting

BTW, limit max width to 800 pixels, crop that in a photo editor.

Clear as mud, right?

Default CPI2 in RV3B

Hi Ross,
I couldn't figure out flickr so I went searching and found smugmug. we'll see how this goes.
I highly recommend both CPI and CPI2 to anyone looking for an electronic ignition.
I have about 5hrs on my new CPI2 and am very happy so far with the performance.
I had used the regular CPI for awhile and switched over for the panel space saved.
It incorporates all of the previous features into one small instrument. Auto backup battery switching is reassuring. Preflight checks are a breeze as well.
I am especially pleased with the fit in my RV3B panel. Sure looks good I think.
Anyone with a single place or centerline 2 place A/C will like the size and ease of inflight use.
I would be happy to field questions regarding installation and operation of this system.
Thanks to you&Barry for a great ignition system and all of your excellent customer service!
Here are a couple more photos . Mike
