Andial Splitter, simpler alternative solution.

[ChrisBennet]

As someone who has previously owned the Andial splitter, I think Sal's solution looks superior. The Andial splitter required you to cut into your DME harness and run another wire from the DME to the engine compartment.

As I read the thread, I was thinking, "That Dave guy sure sounds like Loren." I didn't realize that Loren had been banned.

Steve,

Yes I plan to make a few of these as needed, my plan is to supply a complete solution with per-built harness that you just plug in to the existing 964 coil pack.
Or I can supply the circuit and the 2 connectors with pins for the 964 modules and you build the harness following the above wiring diagram.

Basically you just source the entire 964 coil package with the 2 coils mounted in the bracket with modules installed on the bracket. I supply a pre-built harness with the circuit built into the harness and you just wire up 4 wires in the engine bay.

All this started from a few customers I'm doing MAF systems for that had twin plugged motors and they could not find the andial splitter. I basically decided to build a simpler and easier to wire up solution. With this approach you don't hack into the orginal factory harness. I also follow this same approach with my MAF solution, no harnesses are disturbed.

Just give me a bit more time for final testing and then I'll build up a few kits. I already have parts sourced to build 10 complete kits.

If you provide a complete, finished product, we would be interested in buying them from you since we still have a demand for Motronic splitters on Carrera cars.

Ingo,

Thanks for the support on this project! It was very nice of you to exchange info about how the 964 DME fires the modules.

Once again thanks.

@Loren: nobody cares for your attitude here, how hard is that to understand, huh - either change or go and spew your crap elsewhere, PLEASE

As for price I'm still working on something fair. Please consider that solutions like this don't sell by the 100s, I'd be lucky to sell 20. I do this out of passion for the cars and the owners. If you ever assembled any electronics you know it's not easy to build that tinny board. It takes me about 4 hours to build the entire solution. I had to source all the parts including connectors and then build the circuit, package the circuit then build the harness. It's certainly not going to sell for $75 I can barely source all the parts for that price. Even if I gave away the full schematic most folks don't have the skills or the time to pull all the parts together to build just 1 of these.

Most likely price point will be around $600 for the complete harness, you just wire up the 4 wires and your done. Or about $300 for the connectors, terminal block and the circuit then you build the harness.

Each and every product I make is hand built and tested by me personally.

My goal was to build a simple to use design. This design installs in a fraction of the time it takes to install the Andial design.

I guess I misunderstood what your solution is, i.e. You do require two modules plus
the inverter circuit, the terminal strip, and a special harness. So the cost would be
about $600 excluding the cost of the modules, right? That's about what the cost
was for the NLA Andial inverter module.

Well, for those that don't have another circuit alternative, it does provide a solution.
It'll most likely be available thru Pelican Parts at the $600 price, right?

How is the marketing for this product your responsibility? Do you work for or represent Pelican Parts? Just maybe I've had conversations with Pelican staff that you may not be aware of, has that ever crossed your mind?

Having it available thru Pelican Parts makes it convenient for Pelican Parts buyers
to easily purchase the product when they purchase other Porsche parts they may
need. Kinda like one-stop-shopping as found on other websites, especially since
the product has now been promoted on Pelican Parts.

Hey, I found a really neat feature on this forum:

I did not know the forum supported an ignore list, very handy

Spent the day packaging up the entire coil pack as a self contained unit, here it is:


Everything is pre-wired and ready to go you just wire up:
- Ground
- Power Constant
- Power switched, from existing coil's '+' (black wire)
- Trigger, from existing coil's '-' (green line)

I decided to even mount the terminal strip onto the self contained unit. This makes it super simple to install. All lugs are soldered and shrink tubing sealed. This first unit was created from an old 964 harness. The next units will have completely hand made harnesses.

I'm very please with the simplicity of the setup, very easy for the end user to install and have running in 15 minutes or less since the unit is fully assembled in a neat tight package.

Next I'll install in car and take some pics of the mount up.

Hi Sal,

Firstly, good job! Secondly, welcome to the world of low volume bespoke manufacture. As you've discovered, it's a numbers game. Development hours and build time, cost of parts and of course profit all form the price. It is amazing how many folks don't understand that. They see a few components and wires and in their heads compare it to some mass produced 'equivalent' then baulk at the price. Fear not though, others will appreciate the effort and will buy.

With that in mind and seeing your installation, personally I would re-package the product. Make a single PCB that integrates the screw terminals or better still, has an automotive connector. House that in a waterproof box with well thought out mounting points to make the install as easy as possible. It looks as though the whole thing would fit in a box about cigarette packet size. Let the installer do the wiring or offer this as a separate service.

If you can get to the stage where you are just making a PCB and putting it into a box, you can reduce the man hours and make your job a bit easier!

Good luck with the testing!

[scarceller]

I have a PCB already designed, trouble is I have to cut at least 100 boards.
Your idea of using an automotive connector is something I may consider, I have a decent supply of Weather-Pack connectors and the next unit may be done using that approach. With a connector you'll need to cut the lugs off the stock harness that goes to the coil, not a big deal as the lugs could always be put back on at a later time if need be.

As for price, your spot on! Building limited market solutions such as these is expensive. It takes hours to build and test every unit, people look at it and say, I can build that, till you actually attempt it a lot of people have no idea how hard it is.

I do think that a package that's easy to install with very little labor time has to be worth something more than a package that takes hours to assemble and more hours to install. I know some folks like to do the work and for those I can supply just the circuit with connectors for the BIM Ignitors, then they build the harness.

Thanks for the support

One more detail:
The 964 bracket that holds the coils will not fit into the Carrera engine bay as is, you don't have enough room to mount it like it is mounted in the 964. I took the bracket and flipped it 180 degrees then bent the bracket so that the coils are mounted with the bottoms against the firewall. It's a decent alternative for fitting two coils into that tight space between the fuel filter and the fuse panel tin. I did not have to manufacture any extra metal other than the bar that the terminal strip is mounted on. I'll post pics soon.

Agreed. Great work on this project! Im with Jonny re the packaging. Maybe a PCB mount Deutsch connector or pigtail in a potted case. It would be super clean looking.

In car final packaging!

Remove the old single coil, install the mounting 1/2 of the bracket and prep the lugs onto the stock coil harness:


Take the other 1/2 of the bracket, without the coils but with the harness and electronics all pre-built and fasten it to the mounting bracket but do not tighten the bolt holding the 2 halfs together yet.


Now slip the coils into the bracket and wire the coils to the harness. Then wire the factory coil harness to the terminal strip. Then just wire power and ground wires, these are already pre-wired to the terminal strip.




Finally install the water splash shield, notice how all the electronic including the terminal strip is tucked behind the splash shield.


This twin coil install is very clean, tightly and simple.
That's it your done, now just go drive!

Kevin,

Next is some heavy load testing. But I think the design is solid.

Thanks.

I have had time to really test the circuit in car and it works perfectly under all conditions. Have even done extensive hi load WOT testing. Circuit works very well, next I'm sending it out to the first customer I built this for and he'll be using it in a twin plugged 3.2L within the next few months.

I can easily build more as needed, just the circuit or the complete solution with the harness as well. I prefer to build the entire solution with harness for the first few that go out.

[scarceller]

Here's my 2nd version of this twin coil solution. Just changed the mounting of the treminal strip, relay and circuit can. This one I created the entire harness by hand and relocated the components a bit. It's exactly the same as the prior one but just different engine bay mount up. The coil pack also does not need to be disassembled to install it.

[Bob Gruen]

So once the system is installed (along with a 964 dizzy) a buyer would most likely contact Steve Wong for a revised chip that has less advance than the stock chip, right?
