Again on ECU topic
it very subjective
Basically at first you need to ask yourself
What you want the ECU do for you,
Not the What the ECU can do
Second question is are your budget can fit your ECU requirement
basically..
emanage, SAFC, etc etc also can tune your car
it just will it fulfill your requirement or not only
also don't come with unrealistic budget
like want a ECU to get rid MAF to MAP, can do traction control, launch control, data logging, flybywire, direct ignition, running 12 injector sequention mode
bla bla bla but budget RM2k only
