Clearly you don't know what you are talking about.
Like many have stated, after market ECU's or any other form of after market engine management is only as good as the tuner.
If the tuner doesn't knwo what he is doing, the ECU is useless.
People are only biast against certain brands/types of ECU's because they don't know how to tune them, or they find some other ECU type easier to tune.
Each tuner has a preference, if you tune what they are comfortable with you will get best results.
Its hardly true when you say a cetain type of ECU is "shit". Thats pretty single minded not to mention ignorant.
Do you have any evidence to back up your statement, as I and I am sure many others would be keen to hear why you believe wolf3d is a shit ECU for RB engines?
