Yep! I got my tracking # and it'll be here Tuesday. Wasn't a sketchy transaction at all. He accepts all credit cards now so if anything is sketchy you just dispute it..
Ok enough off topic, lol

@QJS

I know you have done a ton of testing on these. Many like myself have had no issues but many out there are posting about problems. It has got to the point of Epic's having a reputation for being quirky and I am sure you don't want that. Your customer service to me over the years has been nothing short of awesome so I know you are a good guy. You have already posted on this thread so everyone knows you are reading all of these comments and are willing to engage others on the thread.

I'm going to ask you to please talk a bit about the testing you have done to let everyone know the effort put into these units and what they can take. Please address the speculations on heat buildup as a possible problem. Have you gathered random used ignition systems to run with the epic and discovered any "usual" weak links? I expect you have. That would be incredibly helpful to those who have problems from the get go. It seems like it wouldn't hurt to discuss your opinions and knowledge of common issues here.

All of the people you called out for bashing you seem to have responded with either apologies or respectful clarifications so I really don't think this is a hostile environment for discussion. I hope you consider it. I would love to hear what you think instead of a bunch of random conjecture.

I would like to know what components need to be in great working order before attempting to run an hx3.

Good battery with at least 12.4v ocv and good cables and starter so voltage while cranking wont drop too low, stator with a charge coil that is not "tired"- (check resistance brown to ground). Engines that have very high compression have more current draw while cranking- thus lower voltage. ( if near shore, lift pump up to reduce drag). Be sure to insulate the programming cable plug (Mik. n/s cover works well)

So I may have found something on mine, Maybe. Btw, Chris at air time has been great even 1.5 years after I purchased my HX3. Still answers every email and every question .

Problem started after an engine install. Symptoms, hard labored cranking, cranking kick back, rut rut rut, lock, rut rut rut, lock, rut rut starts. Cranking timing with a light shows 12 to 14 deg both cylinders. After the 2 revolution spark delay, the spark starts and the issue is their.

I find no amount of adjustments fix or alter it. My pulse coil puts out 3V AC with only a slight, minimal toggle of the meter needle at cranking speed. I find a spec from JSS of 4 to 7V AC @ cranking speed with needle toggle using an analog meter.

So far it's looking like my pulse coils low output is suspect for sure.

Tonight I decide to change my spark plugs, look crusty on outside and I find have Polaris long reach plugs BPR8ES installed, must have been some mixed in my box order.

Iam speculating this long reach plug may be a factor as well. It puts the spark like 3 to 4mm further into the cylinder. Maybe Instead of igniting the fuel from the dome and burning down towards the piston, it's igniting 3 to 4mm further in the chamber, burning up to dome and down to piston causing deto and kick back.

Might be reaching a bit but it's all I've found and It's consistent with the symptoms. Either way I don't like it.

It's a dasa 1200 @220 psi

Paul Lehr swears by those plugs and I have run them a while with no issues. I used them with a Flame1 and Flame2 ignition.
 
I don't wish to upset those who are disappointed but the contents of these boxes work just fine, and no, I do not get any royalties from anyone. This has been cost effective for me. I do like the performance of the Msd t/l system better (big spark) - have one- but I don't feel like paying that much money for a system for which I have to build a custom watertight enclosure that does not even use marine grade cabling. Afterall, I'm on water, not on dirt or hard surface.P1050368.JPG

out of all your skis what is the max compression you are running?
 
All my skis, including the one with t/l have a cranking pressure of 185 -190 psi (13 atm, I think). They do fine on 93 octane. From previous experience I know I could get by with 200 psi, but that gets risky if I let a racer buddy "test drive" it - yep, seized one. I helped someone install a gen 1 epic in a 235 psi engine with jetinetics f/l. Did not crank so good unless on trailer or lift pump out of water. But geez, a loop trooper with that kind of engine would be expected to have t/l.

thanks, I think this is where my troubles are coming from, Im around 220psi, does not like to crank in water unless you hold it wide open after being run hard on the buoy course. might need to upgrade my battery cables to larger gauge.
 
Yes, whatever it takes to have the engine crank fast enough.- That may also be difficult with some light weight batteries.

that's the thing that has me puzzled, is even after I gulped some water in the surf and cleared it out which was about 15 minutes of cranking, the ski still never cranked slow and ran fine the rest of the day, even would start back up in the surf if I held it wide open. Went to the lake the next day to ride buoys and it still fired up 2 or 3 times. But after the end of a moto where I was pushing myself and the ski just a little bit, which was maybe a 5 or 10 minute ride, the ski would not crank back up at all, spinning over fast each time. It really doesn't make much sense. Im still left to think that heat is involved. However, my buddy who helped test these ignitions used a temp strip on them and never saw anything hot enough to register on the strip. So there is a component somewhere that is not up to par, I just haven't found it yet because the obvious items seem to be ok, stator is basically new, battery is good, coil works well, the ski turns over fast...its kind of a throw parts at it situation.

I never had this problem on stock compression, except for the very first time I ran it and I think there may have been a loose connection or the cdi was sort of "coming back to life" after sitting on the shelf for some time.
 
I hear you, heat may well be an issue and a heat strip indicator attached to the housing of the unit (which is it's heatsink) may not tell you about the health of the capacitors inside. I, due to old age unfortunately, do not ride aggressively, so I'm not a good tester. I'd like to mention however, earlier in the Summer I let a friend (used to be a racer) ride one of my skis, he certainly rode it very hard for quite awhile- no problems noted! I would also like to point out that the charge coil of a stator seems to undergo some aging process, eventually the rather high voltage created seems to have an effect on the insulation properties of the winding layers. These coils then may have issues after heating up. This had me so concerned that I usually "stock" two new oem coils- and no, I don't suffer from anxiety.
 
Well the same scenario happened again yesterday, ran awesome for the first ride of the day when I was warming the motor up for a few minutes, and then no spark/start.

Put the stock cdi in and it worked perfectly. ( Except for the whole rev limiter thing, thats got to go!)

I've had a failing stator do that to me as well but it should be pretty easy to replicate if it's the EPIC. Would you be interested in sending it to me to test?

The loosing spark is a new symptom if I am not mistaken. The OP posted the same issue. I haven't been following the HX3's as closely as I did the Gen 1 Epic but does that seem to be the common complaint?

ScottS fried his HX3 but he blew out a capacitor on it. I can't recall if he had any issues prior to that event though. IIRC, the HX3 was performing great with all the same components that gave him fits with the Gen 1 EPIC. We were all pretty stoked but it didn't last long.

Scott is one of those riders like you described earlier that rides long and hard and builds up heat. He goes through components faster than anyone I know. I throw all my products at him for field testing for this reason. If it stands up to Scott, I know I have done my job right. :)
