i have a PFCON with GCC unit and was wondering what the internal setting in the main unit should be. right now i have it set to 5 and the GCC is flatlined. my mods are:

rebuilt engine
rebuilt turbo
3" DP
3" test pipe
HKS Intake
HKS Exhaust
Greddy BOV

it runs ok but i still have a minor hesitation at a little over 3000rpm. i was just wondering if i should turn it up or not.

also i have the Greddy boost cut controler. does anyone know where and how im supposed to install it? bought it second hand it never came with any dirrections.

 

Yep, the stock internal setting on the FCON is 5. You really need a dyno/wideband to tune the GCC in for proper mixture.

Are you hitting fuel cut? Might want to check some of the Supra web pages to find out how to install the Greddy BCC - they use it a lot.

If you are using the HKS F-CON, it should have a FCD that ties into the harness.

 

i do have one but i dont know where to install it. should i install it closer to the ecu or closer to the f-con?
