Megajolt Lite Jr ??????
Not sure if I should be posting this here, I have a VW type 1 1600 looking to go to a disributor-less ignition, I dont have any experience with EDIS I am good with working on cars and also working around computers, my question is can a do it yourselfer do the programing? and have it run corectly?

You statement of skills is a little ambiguous to give a definite answer, but very probably yes.
Working on cars and good with computers sounds like a good start, but more specifically, you will need some medium level electrical, metal fabrication and software & serial communication skills..
To fit a Megajolt tou need to..
1. Obtain a Megajolt controller, an EDIS-4 module, a compatible trigger-wheel and sensor, and coilpacks and spark leads to suit your engine
1. Securely and accurately mount a trigger wheel to the crankshaft/balancer referenced to top-dead-center.
2. Fabricate a strong bracket to solidly hold the sensor very close to the wheel without vibration or movement
3. Mount and wire up the EDIS ignition module in or near the engine bay/firewall with *quality* wiring, soldering and heatshrink - no twisting and taping if you want it to be reliable..
4. Make brackets to mount and wire whatever coilpacks you use
4. Figure out the firing order that suits your engine and arrange the High Tension leads accordingly
4. Mount and wire the Megajolt controller inside the passenger cabin
5. Find a computer or laptop with a serial port and get it configured, the programming software installed and working.. If you already know about baud rates, ComPort #'s and so on, then you should be in the ballpark there.
6. Understand your engines ignition-advance curve requirements and be able to recognize pinging and other tuning symptoms and know what to do in response to adjust your ignition map appropriately in the software.
If all of that sounds achievable with your current skills, then it should be no problem..

everything sounds posable the only concern I would have is #6 how can I find out more about this?
another question I would have would be how would I get the initial settings?
the default map in the mjlj will work for the initial start up, but setting up the advance curves is actually pretty easy, I just searched the internet and found advance curve graphs for different aircooled type 1 distributors and used one from a 050 dist. put in the values and took the car out and it worked just fine so now im just tweaking the numbers so i can get a feel of what will do what where.
As far as the install goes I bought all the EDIS parts off ebay for 72.00 just search edis4 on ebay and you will find it then got the mjlj unit, read and reread all the info provided on the autosport labs website then read it again, wired everything up (the most frustrating part for me), I did fab all my own brackets and attached the trigger wheel to the pulley myself but you can buy the brackets and a pulley with the trigger wheel installed just go to thesamba.com and search the forums for either edis or megajolt and you will find postings with that info in them.
I was expecting to have problems somewhere along the way but once i had everything installed and the wiring done I hit the key the car started right up, plugged it into the computer all the software worked just like its suppose to, and im just having fun with it at this point, the drive ability of the car has improved much smoother acceleration now im just working on making it better, well worth the trouble in my opinion. 1963 bug 1835cc engle 120, 40x35 heads, weber idf 40 carbs. and now crankfire ignition.

2001 gs, just about any Bosch distributor advance curve is available online. Just use the curve of whatever distributor you have as a starting point. For example, a Bosch 009 has about 20-25 degrees advance all in, peaking around 3000-3500 and starting around 1500 or so. Just put a timing light on it and record the advance every 500 rpm, vac disconnected if it has it.
That's what I started with on mine, but my engine is far from stock: a 2165cc with 9.8:1, Webcam 86B, Pauter 1.5:1 roller rockers, port-matched manifolds, welded 44 X 37.5 heads, and dual 44 IDFs. Puts out 180 hp @6000, 147 ft. lbs. @ 3200.
My files are on here, you can crib them. I used a Ford TPS and adapted it to the Webers.
Powered by section: under Porsche 550 Spyder replica. I don't think my pics show the coil bracket, but you can use the stock Ford escort wires, just add the Bosch airseals over the Ford boots. Mount the coil near where the dizzy was and the wires all reach no problem. Good luck, it is probably the best change I made to my engine.
