I think I could speak for a vast majority of the curious on YT when I say I do look forward to dyno runs before and after if you can manage to sneak them in.
I do hope to get it on the dyno but with my schedule, work, real estate, house shopping, my camaro my girlfriend,,,then my friends schedule, not sure if I will be able to dyno it,,,we shall see,,,I will however continue to post on this thread with pics, write up etc
Regards, Tim

does that work on DIS (coil pack(s) or individual coil packs), like on 3rd gen?
whats teh brand?

are there any other unit of MSD thats smaller for DIS? that thing is huge and too fancy. i think thats an overkill. i mean, youre only after a hotter spark, right?

I may fire it tonight, I have all the wiring set up...
This is what I did though will take pics. Hopefully this is not too confusing
The one place I had to cut the harness was at the coils. I cut the coil harness far enough back so that I could put blue insulated connectors on them, these were female ends, then where I cut them on the other side I put male ends, this is the part with the plug that attaches to the coils...
This way I can unplug it from the coil, then disconnect the male from the female connectors, so that my MSD leads will plug into the coil / engine harness and my new coil plugs also coming from the MSD will plut directly onto the coils...
This will also allow me to swap back to the factory set up in a matter of 15 minutes should the unit ever fail,,,however there is a special wire plug that comes with the MSD box....should the unit fail, you unplug the harness, then attach this special wire plug....it jumps all the wires so that the vehicle reverts back to the factory set up,,,,without having to disconnect the MSD and all of your connections...

After a weekend of relaxing, surfing, fishing,,,I figured I would finish up on the ignition. I got home, wired it up and started it.
I was not able to get it on the dyno, but it is easy to disable, make an initial run without the MSD then another with. I just have to see if I can get it in there.
I also will do some mileage testing....from driving it I didnt feel a difference at all, until I took it on the highway and the midrange and high rpm pulling, to me, is DEFINITELY improved.
I didnt have my camera to take pictures, but should have it tonight, then will take pictures and post them up. The install was simple and can be handled by anyone with basic mechanical and wiring skills.

found this online,,,whatever this means 
The all new MSD Digital-6 Plus Ignition Control embraces advanced digital technology to take performance ignitions into the future. No other digital ignition can match the power and efficiency of the all new MSD Digital-6 Plus.
MSD combines race winning experience with cutting edge technology to create the most powerful Digital Ignition available! The Digital-6 Plus is Digital Done Right!
The heart of the Digital-6 Plus Ignition is a 15 Megahertz microcontroller, the fastest of all digital ignitions. What this means is the controller analyzes up to 15,000,000 critical instructions per second! This is over three times the speed of comparable ignitions and produces the most accurate trigger signals, timing and rev limits possible.
MSD engineers have spent an endless amount of time testing the components of the Digital-6 Plus to ensure the most efficient and reliable operation. The 6 Plus produces more power with less current draw (20% less) by incorporating an IGBT coil driver that can be controlled for improved coil saturation. Also, power MOSFET technology and high frequency magnetic converters require less input current while producing more energy and voltage.
Every spark of the Digital-6 Plus ignition is packed with 135 millijoules of spark energy and up to 535 volts. Below 3,300 rpm the Digital-6 Plus produces a series of sparks that glows in the cylinder for up to 20° of crankshaft rotation. This incredible heat ensures combustion to produce great power, quick throttle response, smooth idle and quick starts.
To prevent any chance of Electro Magnetic Interference (EMI) a filter circuit is made up of state-of-the-art magnetic suppressor components. This, combined with the more than competent microcontroller, checks and rechecks inputs many times to determine “clean” signals before making any compensations. The magnetic input also features a unique microcontrolled feedback circuit for total EMI-free operation.
Features of the Digital 6 include: The ability to switch between two rev limits that adjust with rotary switches in 100 rpm increments. A single stage retard for nitrous and top end performance. A Start retard that eases pressure on the starter, flywheel and engine. Adjustable magnetic pickup compensation that produces accurate trigger signals. An LED display warns of trigger signal problems or faulty charging system. Unit is fully potted with polyurethane for vibration and water protection.
The all new Digital SCI+ Ignition Control delivers the power and accessories that make it ideal for street/strip sport compact cars! High output capacitive discharge sparks ensure complete combustion of the fuel mixture especially at high rpm. If a dose of nitrous is being injected, there is a retard stage that can be activated automatically to prevent detonation from the increased cylinder pressures. To assist with firm launches, there is also a rev limit that can be activated that will hold the engine at a steady rpm so you can launch at full power! The heart of the Digital SCI+ Ignition is a 15 Megahertz microcontroller, the fastest of all digital ignitions. This efficiency results in a smooth rev limit and accurate timing. The ignition installs easily to most engines equipped with a distributor.

another shot, here you can see the tach adapters tucked below the air filter, I used short self tappers and checked beneathe to see there was plenty of room for them to go in without hitting the washer fluid bottle..
typically I use factory mounting holes but on this application, seemed like the best place
these are sealed units and can be completely submerged in water,,,unlike my air filter,,, I will have to remedy this soon with an airbox and snorkel

here is a shot of the new leads that are connected to the MSD harness, these are the coil plugs you can see in earlier pictures...
as there is no direct plug in harness, using this spare coil plug set up made for an easy and clean install
I did have to cut each pair of wires for each coil,,,however I retained the factory plugs that snap onto the coil...I can completely swap over to a stock set up and run on the factory ignition in ten minutes if I wanted,,,also the MSD has a bypass plug which disables the MSD and runs through the factory igniton...this bypass plug takes seconds to plug in

if anyone has questions, or is going to wire one up, let me know, I would be glad to help...it was a fairly simple install, anyone with basic knowledge can do it...will post my MPG soon, after my first highway trip
