I'm sure getting my hands on a base map will not be very difficult and a friend of mine owns a shop here in Huntsville by the name of
TrackMasters. I haven't spoken with him about this but his website lists MegaSquirt as an ECU he tunes.
This whole project sounds like it's going to run me a few dollars more than the $350 I was hoping but I'm going to start taking steps toward it soon. I just can't live with a the acceleration I get with a stock 4AGE in a car that handles so well.
