MSII Help req

Hi guy's
I'm a little stumped and could use some advice here.
I've recently upgraded my MS1 to a MSII setup to gain better control of my large injectors.
While the car was on the MS1 setup I was using a base map provided and the car would start and idle, albeit very roughy and rich. I didn't do any tuning with this map (other problems with the car etc)
Now I've upgraded to MSII and put the same values into MSII as I prevously had in MS1 and the car isn't firing. It's trying, sometimes it catches but it dies immediatly.
I'm not sure what to change. I know my timing on the engine is out. If we adjust the dizzy while firing it sounds better and catches a little more but still will not fire. I've got the Trigger Offset set to 60 in MegaTune. This is the standard setting for my engine. My first job, once I can get the car idling will be to set the timing to 10 degrees BTDC on the car. In MS1 there was a setting that allowed you to set a fixed location before moving to a map. I've not seen anything similar in MSII.
The major changes that I have noticed in MSII that I couldn't find any settings for are ignition and Dwell. For the ignition I used the recommended settings for a Bosch 124 (Hall effect). The stock dizzy apparently uses a crank sensor as normal but has a Hall affect sensor as backup.
I've set the Dwell to 3.8 maximum charge with a 0ms acceleration value. This might be totally wrong, but in MS1 the maximum value for dwell that I ever saw was 3.8.
Another avenue that might be wrong is the ASE values. My car has no idle control system. It broke and proved impossible to get a replacement so it was removed. The stock ECU didn't have a problem with this even in winter.
Finally, one thing I have noticed is the the MAP sensor is reading 98.9KPa. This is normal evalavation for where I live, but my ve and spark tables are all starting at 20Kpa. I get the impression that most engines are pulling smaller numbers because they are fully closed. I've opened my PCV system to breathers (the engine has been turbo'd).
Because my engine is seeing nearly 100kps at rest, I've tried to make new VE tables that start at 90Kpa. My thinking being that it will always see at least atmoshperic pressure. MegaTune says no, and generates a table starting low but fills with with random values. This is no great problem anyway as I have no idea what HP and torque the engine will make so all I can do is guess.
This is way over my head, and progress is slow. If anyone's got any ideas it would be appreciated.
The engine is a Mazda KL 2.5 v6 engine. It's been turbo'd, is running an overbored TB and 880CC injectors. The fuel pressure has been knocked down to 22PSI constant, and the REQ fuel requirement is 4.4. The injectors are high impedance. I'm using MS-II, megaTune 2.25b717, v2.2 board.
