Ok, so recently I have been looking for a boost contoller because right now, I'm running minimal boost using a small wastegate spring for boost control. Well I was talking to my friend about getting one and he jokingly asked me if I was getting a fuzzy logic one. I asked him what the hell he was talking about and why he was laughing, he said it required a 5th gear pull for like a minute for the controller to learn the car. I had no idea what he was talking about, and it sounded retarded. I asked why you couldn't just do it on a dyno, but he was saying that it had to take wind and such into account. That sounded even more retarded.

Anyway, so I did some looking, it seems like a fuzzy logic boost contoller just basically can learn your cars settings, however, from what I read, you just need to do about half a dozen 3rd gear pulls, on the street or dyno for the controller to learn. They can learn the characteristics of your turbo and are supposed to be able to build boost faster?

My question is this, can anyone give me a better definition of what a fuzzy logic boost controller is? Also, which boost contollers out there are fuzzy logic? I was reading something and it said the Greddy Profec A was fuzzy logic, which I'm pretty sure is an older, now outdated boost contoller?

Thanks

P.S. - I put this in here for the NA-T guys since they are very knowledgable and helpful. I was sure if I put this in the MKIV section the TT and APU guys probably would have flamed me, but if a mod feels like it really shouldn't belong here, they can move it.

So the E0-1 is a fuzzy logic controller? So my understanding is, instead of setting the boost, it determines itself what boost you should be running based on the cars reactions and such?
