looking for a base map and tips
i'm going to be doing my install in a couple weeks and would love to get a place to start. i currently have my stock '93 running on MS with a pretty good map, but i'll be installing a greddy mani/turbo based kit with striped IC and some 440CC injectors.
an tips on the best way to get up and running once i get the install finished, and/or a good base to start with, would be super appreciated, since i'm a little intimidated with the prospect of starting from scratch.
i'll be boning up on the megamanual again this week, hopefully digesting a lot more of it this time around. :-)

Set the req_fuel for the 440's (MegaView can calculate this for you under "Basic Settings > Engine Constants"), then scale your Cranking Pulse Widths (under "Crank/Warmup > Cranking Settings), and your Accel enrichments (under "Basic Settings > Accel / Deccl"). The MegaSquirt PNP manual describes the process pretty fully - by following those directions to modify the base map, my car started first time, and ran pretty well right off the bat. Basics are: subtract 1ms from the base cranking and accel settings, scale the resulting value by the base injector size vs your 440's (somewhere around 55 - 60% - base '93 injectors are somewhere between 205 and 230, depending on fuel pressure they're tested at), then add back the 1ms. Again, read the manual: it's pretty clear about the process - if you're not running the MSPNP, but your MS is running fairly well, these suggestions from the manual SHOULD still work.
