ive done abit of work with dta and find it a very hard system to try and map, ok ive no experiance with it until this project thats been happening , but ive been unable to adjust the ign/fuel real time on each individual load site, th eonly way was by a global adjustment in either a percentage or by numerical value, there are also a hell of a lot of setup procedures related to the the closed loop setup before you can use it to set up the fuelling. was considering it for my own car but after trying to use it for a friend found it very UN- user friendly - will look forward to hearing how you get on pal.

oh and as for the maps, im with bill, ign sort of ok enough-ish , the fuel all relevant to your fuel system pal
