The newly released JSTL Inc, TL ignition module...with a touch of OCD!

Both Jetinetics or MSD will work. The MSD is just more expensive.

All that is required is to remove the stock magnet(s), enlarge the hole to 3/8" and epoxy in the single replacement magnet, (south pole facing the hall effect sensor). The target gap with the Jetinetics is 4mm but this system uses such a strong magnet that the tolerance is actually much greater than that.

The newest version of the installation manual details everything you need to place the magnet correctly.

I have a good used MSD on it's way but I put out feelers for a trashed flywheel to run on my bench in the meantime. It finally showed up today and here is what it looks like with the new magnet. The hall effect sensor gap ended up being right around 1.5 mm.

My new timing light arrived on Sunday so I was actually able to proceed with testing and timing verification.

I'm somewhat new to total loss so it took me a bit, (not to mention a few phone calls to Denny up in Canada), to figure out and correct for where I placed the magnet in the flywheel. The manual calls for 40deg static timing when used with the Jetinetics flywheel but I found I had to set mine to 32deg to match my installed position.

I made a few other TL rookie mistakes along the way but basically, once we got the static timing resolved, I was able to put this thing through the paces and couldn't be happier. The unit performed flawlessly and I went through several different curves. I started with a flat zero, moved to a flat 15 and then a 30 and then loaded the original "dyno tested" curve the unit came with and ran through it all again. The new digital timing light I ordered (Innova 5568a), has the advance feature so while running the unit through a full range of RPM's, I was able to use the gun to verify exactly what the monitoring software was showing.

The flywheel I have been using for testing is missing the ring gear and has a chunk missing from the keyway so I needed another flywheel before I could move forward with putting this unit in an actual ski. I ordered, (and have now received), an MSD TL flywheel so that plan is moving forward again! The profile of the MSD is slightly different than the Jetinetics so I am going to have to machine 4mm off the height of the hall sensor standoffs in order for the MSD to clear but that is a minor detail when you own a mill.

Also, this MSD flywheel is one of the older single channel units with dual magnets, (plus the placement is different yet again), so I will have to drift out both of the original magnets, mark and drill out a new location in a place it to match the Jetinetics.

I had lunch with ScottS today and he has agreed to be the test rider on this one so stay tuned for a ride report shortly. I'm hoping to have the unit ready to drop in this weekend but while I say this, I am also backing up with other orders as I have been spending so much time on this project lately. Hopefully I can get it all handled and nobody has to suffer any more than absolutely necessary, (other than my spouse that is). ;)

I bit the bullet today and machined 2mm off the stator plate standoffs so the hall sensors will clear the MSD flywheel. I could have taken more but I wanted to ensure that this unit would still function with which ever flywheel was chosen without shims or further modification.

I then drove out both the OEM magnets and redrilled it for the single magnet. I don't know what MSD used to glue those magnets in but they had to come out in pieces.

There was some confusion over the correct place for the magnet so I drilled the hole in the wrong spot at first. Hopefully the additional hole doesn't weaken or throw the balance off too much.

I snapped a couple pictures to show how I referenced the position of the single magnet.

I wouldn't be too worried about machining the lugs down, shimming back up shouldn't reduce any accuracy radially.

I agree. I'm just trying to keep things as standard and straightforward as possible.

And as you can see, I was able to use that flywheel after all. Just took a little commitment.

I wrapped up bench testing today and am finally ready to move on to water testing.

My confidence is very high at this point. I have not come across anything while testing to even slightly suggest there may be any issues. In fact, the RF created by the open spark style testers I use has been known to cause all kinds of problems on other digital systems but this system took it all in stride. I have long suspected RF as the main reason for issues with digital ignitions so passing this test alone is a huge milestone in my opinion.

We are going to try it out on a limited 701 with one of our tailored surf curves so I went through my library of timing curves tonight and got most of the standard curves entered into the software so I have them at my disposal.

- Scott's Surf Curve
- Boyer's Surf Curve
- Baseline 0deg flat
- Baseline 15deg flat
- Dasa 10mm Stroker
- Stock 61X/62T CDI
- MSD Enhancer
- Aggressive Stock stroke

The unit came pre-programmed with a dyno proven curve for the 960 Etec with race gas setup on curve #1 and pump gas on #2. I'm told this is a great curve proven to work well on a wide variety of motors but we wanted to start with the exact same curve the ski was running before so we can better establish a baseline around function and then let all you flatwater tweakers worry about the performance end of things. :)

Putting it in Scott S hands for testing will give it the true real world workout for great confidence in market. Glad to see this unit is getting released,A reliable programmable total loss ign has been like the golden unicorn of jetski wishlist parts for years now.

I am running the jstl system in my phantom it took a few days to verify the system is functions as advertised we were able to time the system in my boat while running the engine it was 40 degrees as stated by Dennis we pulled timing out earlier then the supplied curves and then decided to burn our own the the first test ride the ski only ran on one cylinder we discovered that the way we routed front the spark plug wire was causing interference with the unit re routed the wire away from the unit problem solved I'm only a couple hrs on the ignition so far it's working perfectly these will be going on all my boats if it holds up IMG_7050.jpg20160213_154727.jpg
 
Any Update on this ?
We have been running this unit for about a week now without any issues. Initial set up is a little different, but once u understand, it's really simple!! Been working great, went through an entire 5gal of fuel yesterday without a single problem. Besides our pump not hooking up!! Lol Time to start tuning the pump!!
