Actually map 1 is also around 270whp but it's designed for the 328 while map 5 is designed for the 320. The map that made 300whp was map 7 using E85 and the flex fuel connector. They have also added a Stage1 simulation to the Stage2 box.
Don't get too concerned with map numbering yet as I understand they are going to redo the numbers soon. Mike |

wow, this is looking too good to be true. If a tune can get 260+ whp out of the 320i, this might just be my next car. I can only imagine what a full exhaust system would add. That stock exhaust just screams restrictive to me.
Here's to hoping BMW doesn't decide to throw the B38 3cyl turbo into the 320i in a year or two and limit the tuning potential. I think that prototype engine is running something like 14 psi stock, and I cant imagine it taking much more boost.

How much boost was "Map 5"? The big questions still remain:

I doubt that everything is the same. It would make the cost of the 320i too expensive to make. Doesn't mean you can't tune it to make power I would just question the longevity of the engine. As wonderful as these piggyback units are they aren't exactly the most sofisticated way of tuning a car. Have these guys cracked open an engine? Have any mathematics been put into this? Or is it just trial and error being used?

So for 320i is just map 5 (stage 1)? The installation is default, or do I need anything else?
Thanks!
