Today I finally installed my Greddy Profec B Spec II, replacing my MBC, and everything went fine until I went to set up my high and low boost settings. Does anyone know the trick to doing this? I followed the manual and all i could set was the % gain high and low, it wouldnt let me change the boost settings. I was able to change it to psi. My setup is a Hondata 2b tuned to 12 psi. Does anyone have any suggestions??

 

Sounds a lot different from the original profect B...if its just as simple, it shoud just work. Set everything as low as you can go and gradually bring it up to desired boost level...

 

Overlooking the instructions.. you want to be in the "SET" menu (which is before the "GAIN" menu)
In the SET menu.. you have a % to adjust which will set the desired boost level.
Per Instructions:
**100% set will boost up to the turbocharger/wastegate's limit
**0% willl boost the base boost (ie wg spring/stock boost)

Re-read the SET section in the manuel.. pg 44..

Hope this helps ya

 

Anybody else? How did you guys setup yours?

 

Bump.

 

you cant adjust your high and low settings by inputing the actual psi that you want. you just have to keep raising the percentage while you are driving to get the exact amount of boost you want.
