    New Stand Alone Electronic Ignition System

    We are about 1 month away from release of our new CPI ignition product. This is a user programmable crank triggered ignition driving a coil pack. Product includes module, coil pack(s), Hall Effect crank trigger and wiring harness.

    Features include programmable ignition timing with rpm, retard and advance with MAP (internal MAP sensor in module), optional knock control, real time readout of timing, warning and setup LED for magnet/ sensor alignment, cranking retard, coil charge time, magnet offset calibration, MAP units in gauge pressure or inches Hg Ab. First models available for 4 and 8 cylinder engines. Six cylinder model to follow.

    Applicable for engines equipped with carbs or mechanical fuel injection where people want to ditch the OEM distributor setup or mag(s). Eventual bolt on kits for Subaru, VW, Lycoming, Jabiru and Rotax plus most auto engines. Single module can drive 2 coil packs on twin plug 4 cylinder engines. Based on proven hardware/ software from our SDS products with over 13,000 units in the field over 21 years.

    Re: New Stand Alone Electronic Ignition System

    Hi Ross,

    nice and still very needed material!
    The picture make me believe that you don't need additional hardware to tune the device. Is that the case?
    Can you drop an idea of selling price?
    It's probably a bit of overkill for a 1 or 2 cylinders twin plug engine but if the price is correct, who cares?

    Correct, all tuning is done with the keypad and LCD on top. Size is about 4 X 2 X 1 inches. (10 X 5 X 2.5 cm).

    We're aiming for a price point of around $700US for a 4 cylinder, single plug setup which includes module, wiring harness, crank sensor, trigger magnets and coil pack. We have done some twin plug, 2 cylinder engines in the past so that's a possibility with some software changes if there is sufficient market interest. One cylinder market is too small I believe at this price point.

    On the popular engines mentioned above, we'll eventually have complete bolt on kits with CNC'd sensor mounts, magnet discs (if required) and magneto block off plates etc. Some of those parts are in process right now. This will make installation easier and faster. Price on those kits will be a bit higher of course.

    Re: New Stand Alone Electronic Ignition System

    You mentioned 6 cyl as an eventual release... Do you have the Lyc 540 in mind?

    Ive been waiting very patiently for Emagair to finally deliver the P200- you might beat them to the punch!

    Lyc 540 kit could be in the future. I have access to a 540 nearby to do some measurements on. It already has one of our EM-5 F systems controlling spark on one set of plugs and raced at Reno. Right now we are so buried in work it would be a while though.

    Re: New Stand Alone Electronic Ignition System

    If I went with your system could I program it for a dual plug V4 firing 0-90, 360-450. I need it so one pack can fail and one spark in each cylinder remain operational. Would I need four packs or just 2?

    P.M. if preferred.

    This is a waste spark system and can only be used on engines with evenly spaced firing intervals. On a 4 cylinder, twin plug per cylinder engine, you can wire the coil packs (CPs) so that failure of one CP will allow the engine to run on the other CP. We use a Subaru CP. We've done over 400 of these in aircraft and cars over the last 15 years, never seen a one of them fail. That is a main reason to use them plus they have built in drive transistors, simplifying wiring and the control module, are waterproof and engine mountable.

    Re: New Stand Alone Electronic Ignition System

    Can it be hand propped or does it have to go through one complete revolution before it knows where it is?
    Conventional wisdom and practices yield conventional results. If that is good enough for you:

    Re: New Stand Alone Electronic Ignition System

    It's not bad looking at all, I can run a wire to each plug, using one of these on the left cylinder bank, and one on the right cylinder bank (8 plugs). If one of the coils fails, which is apparently very unlikely, it will be able to run off the remaining one.

    I'm sure your busy with getting the release of this out there. I'll look around for something similar in my target size.

    Could not be hand propped unless you can get a full crank revolution and even then it would be iffy. BTW, this coil pack weighs just over 2 lbs.

    Ross,

    Looks really great! +1 request for the O-540 here too (28V).

    Thanks. Won't be any 28V version though.

    With a similar price point, you would dominate the RV-10 market. I'm sure you've done your market research, but I would think that jumping on the 540 bandwagon would be a priority. 9,000 RV's completed and flown....

    Just sayin.
