Tim you can do exactly this. It is very possible and has been done and dicussed on msefi.com. You will need to install the intake and coolant temp sensor for accurate results.

You will need to setup all the constants as you normally would but the changes will be in the VE map. you basically only want the MS to start adding fuel at the 101KPA value. all the map/RPM values below that will need to be changed to a value of 1 if i recall. if you put in 0 the injectors will still add fuel for some reason. This was the problem discussed on MSEFI because another member was getting a way to rich condition. Looks for the posts on MSEFI for confirmation. If you cant find them let me know.
