Glad to hear it's working. Figuring out all the PC-side stuff has got to be the hardest part of getting started with MS. The documentation on it is so scattered...
So, this code will be good enough for testing. Before you install it on the car, you'll need to use a program called EasyTherm to set it up for your car's specific IAT and CLT sensors. It's a strange process- EasyTherm actually modifies the .s19 file (the raw code that goes into the MS) and then re-flashes it, which in itself is a whole different tutorial. It's not hard, but it's non-obvious at first how to make it work properly.
I suggest that you download the HiRes code when it comes time for that. You don't need to go through the whole process of re-installing MegaTune, you'll use copyini to update MT's config file, and EasyTherm (instead of download-firmware) to reflash the MS with the new code.
The latest and greatest HiRes code is always posted in a particular ongoing thread at the msextra forum: http://www.msextra.com/viewtopic.php?f=90&t=25336
HR10g is the current release, and it's what I've been using for quite a while. Also, there are a couple of .inc files you'll have to copy manually, I'll help out with that when the time comes. Another one of those things nobody bothered to document because "everyone knows that."
