To print with ABS you need to put your printer inside an enclosure. Otherwise the parts will always warp. Also, you can add a brim and make sure you turn your fan speed down.

 The bed temperature needs to be 105°C, and the nozzle needs to be at 245c

As Samuel wrote wish I read that some hours ago, I came to the same temperatures.  Use 2-3 layers skirt.
I print open in a small room, only taped a towel on the front of the frame because when I go in, I dont want the wind on my print bed.  Should work! Dont forget to clean and clean with methylated spirits.
Thers one and a half hours to go, hope the duct will be finished.

Just wanted to give an update, the print is now finished and its looking great for the realy first ABS print (I only had one retraction test print on ABS what was also a good result.    
I only can give you the only tip, set the first layer realy low but dont over extrude! 0,15mm would be perfect with an 20 round skirt, 2-3 layers high as in the picture.   A warm small room is enough to print that ABS.
