My GT4 with a jap-spec 3sgte and euro ecu is showing typically 14-15 on my air/fuel gauge. Is this too lean? My mechanic said that i shouldnt use the jap-ecu on 95 octane... Im running 15 psi turbo pressure.
Going on a road trip tomorrow, and i dont want to mess up my car again. This post has been edited by skogs: Apr 11, 2014 - 3:15 AM |

10:1 is very safe
12:1 is reasonably safe 14:1 is agressively lean (less than safe) 15:1 is dangerous (knock) This post has been edited by playr158: Apr 11, 2014 - 9:46 AM |
