Nick, thanks for the *.msq file. Here is the ignition map :
I'll try it out on my car this weekend. No problem for the pages, I can just export and import the spark map, naturally I'll have to retune the fuel table but that's easy
.
The upgrade to MS2 was very easy, you just take out the MS1 processor an put in its place the MS2 processor board, then you'll have to convert your MS1 setting to MS2 Extra firmware, it's not hard. You get 16x16 fuel table, 12x12 AFR table, a faster processor and a lot of more options. Over all my car runs a lot smoother with MS2 and in my opinion it's worth upgrading.
I got this MS2 cpu board

P.S. looks like your running a 400kpa map sensor .
P.P.S On a quick glance at the maps, I have more ignition timing in the lower kpa range and you run more timing in boost, however this is not my latest map, I'll upload the one I'm using this evening .
