you are right about fueltech local help ! but they have a fantastic support on facebook ( UK or USA )
I've just download the Holley software and watch a video how to install a dual sync dist by Holley, I beleive it was more difficult and the sofware looks pretty easy to tune.
A friend who has a lot of knowledge in EFI told me that the Link G4 ECU ( Storm or Xtrem ) are very good too but not really cheap

Having used both, all my personal cars use Holley dominator. The software is easy to use and with V4 advanced tables you can do almost anything you can think of. Most all name brand EFI ecu can do the same thing but look into growing down the road. N2o, boost, meth injection,traction control, transmission controller etc. Holley is one box, not several add on boxes of modules.
If you dont need many inputs or outputs then the Holley HP ecu will do. If you can do with 4 ins and 4 outs then the HP ecu will work. The Holley will allow you to grow. AS with most systems you can tune in speed density, alpha n or a combo. Most everyones helps lines are severely lacking in the CS dept.
If you are going to have someone else tune it, then use what they prefer. As you can tell my vote goes to Holley.

yes, it is the same as gas, change a drop down box, or use a flex fual sensor and advanced tables for fuel and spark compensation . yes dual o2 sensors(you can pick leanest, richest, average or individuals) , and yes knock sensorsup to 2 and have frequency control so you dont have to use a specific sensor . cant remember on the FAST.
