Safc2 question please help
Hey guys I have a question about my tuning I'm just leaning about this and I'm doing good at it. As of right now I have the car boosting 15psi and a/f is at 10.9-11.5 witch is where I want to be.
I just need to know once I fine tune the car and I have my tune set up how do I tweak the drivability? What I mean is when I'm drive to work and I'm not in boost in just chilling and driving how do I lean it up alittle so I'm not burning so much gas. Is that even possible or it is going to be set to run little rich cause of my tune being rich? Is there a way to tune it so when I'm driving to work it shows like low 14s in vacuum? I think right now its showing like 12.s and my gas is burn up quick. Thanks all. |

The safc allows for tuning high throttle amd low throttle by adjusting the set points. Open the data monitor on the safc and watch your throttle position when cruising. Also pay attention to throttle position when it starts to build boost. There will be a lean spot between the two. Set cruise under that lean spot (low throttle) and set your high throttle map above that lean spot. You set it up under settings. I think mine was 30% at low throttle and 55% at high throttle. Then you go back to the tuning menu and select low throttle then slide across the rpm menu and reduce the amount of correction at the rpm you want to reduce. I think I had mine around 15-1afr at cruise then dropped to 11 at tipin and rode out at 11.5

1/ Bin that piece of crap 2/ buy some real tuning device. Cheapest would be a nistune but it is only a daughterboard on the standard ECU. You cant do jack with a piggyback. |
