Hey guys, I had a friend of mine help me mess around with my Greddy profec b spec 2 ebc because I had no idea on how to work it. The problem is, is that he says that the settings and a few other things are different from any other profec b spec 2's he's used/seen.

Like the way you can set gain, you are supposed to be able to go from 0-100% but it only goes from 35-75. And gain set should be 0-100 but it goes up to like 250.

Is there different versions of the spec 2? I bought the car used and it came with it already installed. I've always used MBC's so an EBC is a little different for me.

Another problem we had was that it was surging when building boost. Even though it might just be a boost leak, the only way we were able to stop that was to lower the boost %, which I didn't really like.

Anyone ever hear of this? I bought a Hallman mbc a while back that I have sitting in my room. Is it time to switch over?

Thanks!

 

look up the thread on how to tune the profec so you dont blow your motor...its a bit confusing but read the instructions carefully

 

No, the car runs fine, minus the surge sometimes. The car was tuned by TTP.

 

I dont like Greddy Products. Im running the e-01 and while it works, I just dont like it.

 

i got a greddy profect b spec II and that thing is great i make full boots (22psi) at 3000rpm and hold it all the way to 7300rpm

 

it's probably the user not the unit. My greddy profec b II worked flawlessly.

As mentioned, check your settings and adjust per the instructions in the how to thread.
