And for the ecu question. Nothing is better than a stand alone but the e-manage ultimate is the best bang for the buck. Coupled with an LC1 wideband sensor it self tunes to make initial tuning so simple and fine tuning is a breeze after that.Also I love that you can now lower injector duty as compared with the blue e-manage i use to have. All tuning I did was done through the injector duty map without touching the airflow map. The problem with the previous e-manage was that most tuning was done using the airflow adjustment map wqhere u adjust your AFM signal to make the ecu take a fueling point at a different area of the fuel map but on the nissan ecu that fueling point based on airflow/rpm is mirrored onto the timing map so alot of times adding more fuel added more timing which isn't good for pump gas.The Ultimate adjusts airflow signal for injector correction only and all tuning can be done directly at the injectors using duty cycle.One big plus about the ultimate is the number of features and it has built in launch control which works like a dream and got me up to 12psi of boost on the launch and also the ability to adjust fueling according to vehicle speed and engine temp. The datalogging is also awesome.It is all a personal preference though.
