I agree with Fred. All the EFI users that I've ran into are happy to share maps and vise-versa... There are slight differences from one car to the other and one setup to the other that will likely need some fine tuning- of course that's kind of the point.
For instance, my maps work seemingly flawless on Clayton's car and they're close for Dave's car... But Dave's car requires more fuel and less timing than my car. There's a whole host of reasons for what causes this. You don't have to be expert to deal with it, but you DO need to be willing to tinker with it and learn the software. Once the car is dialed in, you can leave it alone until you change the setup of the car. Then you run up to the dyno and do a little tuning to "unlock" the power of what you just bolted on... Of course, sometimes the things you might bolt on hurt power which you'll find out on the dyno as well
So in summary, if you build your car similar to what has been done, chances are you'll only need to make small changes to get your car dialed in. As you continue to grow more comfortable with the software, you will likely start making changes that you prefer, such as cam switch points, etc... You don't need to frequent the dyno unless you're trying to really get all the power out of it, but you will need to be able to watch your AFRs on a wide open and some part throttle areas to ensure initial fuel settings are OK. This can be done on the EFI software with a buddy in the car to watch the lap top or at the dyno--- preferably on the dyno so you can be sure that who's ever tune you start with has enough fuel in it for your car...
Hope that helps. Perhaps Dave, Ronnie, Jim, etc might have more to add...
Best,
Phil
