Hi I am interested in getting an additional ECU for my Nissan but as we do not have JWT here in Singapore would just like to read up more on what makes a good ECU and what does a ECU actually do?
How much power increase will there be?
Here in Singapore we have bascially BuddyClub, Apexi and EManage ECU ... wonder if you guys heard of these brands before? I don't know anything about ECUs and would like to read up more ..
Tried searching on Goggle but to no avail .. nothing turned up ..
Kindly direct me to some sites on ECUs and what is good and what is not that good ...
Heard that after getting a ECU we will need to go for Dyno Tuning to set the settings in my ECU?
I am using a QG16DE engine by the way ...

wonder how much performance increase that will be for me
Thank you for any help.
