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 |

I get consistently 14-15 while cruising and at mild acceleration, is this critical? Or is it just at wot that it shouldnt be that high?
I dont understand why it would be a wrong ratio, i only have som common mods: - 3" turbo back exhaust - Cone air filter - stock blowoff valve - blitz boost controller set to 1 Bar - jap 3sgte w/o egr - euro ecu I havent had the balls to stare at the a/f-gauge while at wot yet.
