in and of itself yes,but multi spark and dual dig....eh not really

What engine package are you running yours on? I haven't changed my jetting yet and have run thru several different curves on my SS865. The Enhancer curve leaves my plugs a little rich but still running very strong and safe. The most advanced curve Chucky sent me turns my plugs a perfect shade of brown and absolutely rips. When we first started playing with curves we watched our jetting pretty close bit i have faith now that we are fairly safe within the established confines. If i go anymore aggressive than already established, i will definately verify plugs again. I think the smaller engines may be less forgiving on jetting than the bigbores when adjusting timing.

Dude if your going to keep making smart ass remarks about things you dont knowabout,at least read the rest of thread that pertains to it,start with post #10
Chris. Is the flame a dual digital setup like the msd?I know the older msd units were single pickup and not digital.The combo of being multi spark and dual dig gives me the smoothest idle and fastest response ive ever had on any ski or ign. I may try the flame someday if this msd ever craps out,this really is a "ingenious" idea for sure with programmable curves and selector switch for 2 curves,makes great sense to me if you ever have to figure out a motor yourself
OCD..Id of never guessed solenoid,but it makes sense,if it was not making a good connection,this could be enough resistance to drop voltage to 10v, why does the ign advance start timing at a lower voltage in the first place?
I dont go research each and every post of yours, just went by what you posted. There were some guys in florida years ago that were known as the Surf Sluts, a few of them ran with no electrical boxes (front cover). So, who knows what you might be doing.

Add the solenoid to that list as well. We are not sure of it's caused by a bad contact on the solenoid or interference, (electrical noise) from the coil backfeeding to the unit but replacing the solenoid seems to have fixed the cranking issue.

When people post about hard starting, it is hard to tell if they are talking about the mechanical aspect (Starter) of it physically not wanting to turn over, or the electrical aspect of it not firing off.

Well that topic is even more complicated lately since the introduction of the EPIC. Scotts ski started up fine before but suddenly was struggling to start as soon as he installed the EPIC. It gave similar symptoms to a weak battery, bad ground, bad starter, etc... Swap back to the Enhancer and it starts fine again. We suspected numerous things and did lots of parts swapping before finally swapping epics and proving that the problem was with the ski itself. Since we already changed everything else, we had it narrowed down to a set of relatively new cables or the solenoid.

doing that kinda detective work really sucks,been there done that,props to you guys for finding the issue

We hope we found the problem anyway....only time will tell.
I don't mind the troubleshooting, that's what i do professionally but the 5hrs of driving to hand over my EPIC and sit on the beach watching them wrench instead of ride gets painfull, lol. Oh well, surf was flat and it was meant to be a tuning day anyway, at least this way we accomplished something.
On the flip side, it was fun showing them how to pull a tank and b-pipe in under 5 minutes without removing the battery though. And they said it couldn't be done, sheesh!! :biggrin:

Well here is what I did today..........Managed at last to get a ski over here showing some of the starting problems reported with EPIC, this was the first chance I've had to witness this for myself. Unfortunately the electrics and flywheel had been stripped so I wired it to spin the starter without the flywheel fitted so the starter was off load...fitted a current drain meter, hit the start button and horror of horrors, as I hit the button the meter went off the scale (more than 75 amps) then settled down to 50 amps, remember this is off load! This was an aftermarket starter. I then tested a new OEM starter and the initial hit registered 50 amps and then went straight to 25 amps. Giving that the gauge went hard over with the aftermarket starter I think it quite possible that it is in the region of 100amps. This is probably enough to very quickly reduce the battery voltage to well below the 6 volt protocol required for this kind of device. If this is in fact the case the processor in EPIC would shut down and then re-boot when the voltage came back up and throw out a random spark which could cause the engine to kick back.
I then fitted a new OEM starter, hit the button and the ski started and ticked over perfectly.
It seems at the moment we are having to spend a lot of time making EPIC cope with issues on ski's that shouldn't be there, but on a positive, at least when we come out of the of the other side of this we will have an ignition that will ignore the smell when your ski farts.

The bigger positive is that you are willing to do so. This detail alone sets you on top in my book.
In my field we are constantly looking for a balance between perfect maintenance and forgiveness. Quite often we spend countless hours tuning equipment and programs to accomodate minor, ( and sometimes major) mechanical and electrical deficiencies. In the end it keeps us competitive, lucrative and relevant which all adds up to us still doing business when most, if not, all our competitors are not.
Keep up the good work Chris, hopefully we are on tbe downside of all this and you and Lisa can get back to sleeping at night. :biggrin:

i finally got my ski running good. make sure your coil is good. my wires where good, my ends where good. the coil ran good with the oem cdi. i replaced the coil with a new one, put the epic back in and it runs like a champ.
if you are having the back firing issue or it dieing after high rpm's, check your coil.
thanks for all your help chris.

So it will not work with aftermarket starters?

no one should even bother with a/m starters anyway,they all suck,some dont even have internal liners to keep magnets glued from both sides,the aqua torque and many other brands have all failed for the wavejunkies that tried them. A used oem is far better than any new a/m starter.
ocd,thats cool you did that for scottS he is one cool guy,hes the type of guy that would do anything for ya .ask him bout the time we went out at hugo,just the 2 of us on both his skis,mine was nose crunched from week before. unfortunately they both died,a few min apart half way through the ride...fun long swim in,lol

X2, Scott is a solid guy and a very good friend with a big heart. Anyone that has ever met him can probably recall a few times where he has helped them or someone else out so it's great to be able to return the favor for once. We were joking on the weekend that the Florida crew has Fred as their Guru and we have Scott, lol.

I'm running on a 780 BB made by #Zero. The safer thing is to check the plug like you said , imagine you are on the edge very close to lean carb changing the curves can make the things worst. Changing the timing on a motor is not a small mod. Jjust my 0.2 cents :beerchug:
I just wonder why there is no discussion on setting "cranking timing". No edit cables?
What is OEM "cranking timing"?
What is Enhancer "cranking timing"?
What is T/L "cranking timing"? (I notice it's has two settings...me thinks)
What happen when there is to much timing at cranking?
What happen when there is to little timing at cranking?
At cranking, how much cylinder pressure is caused by compression stroke and how much is caused timming?
If there is not enought cylinder pressure before ignition, will the motor start? Or, will it fill the exhaust with fuel/air?
Anybody having issues with hard cranking and backfiring?
?
