i have 7mgte that is really running rich. i found a broke wire on 02sensor (repaired). Car still running rich chked intake sys. for vaccum leaks all repaired. For fuel management i have safc/vpc. The car cranks okay, but when start you have to keep foot on pedal,but when release pedal car stalls. i have AEM wideband and the car don't start rich, but in about 3sec. it's rich. Tried to adjust fuel curve with safc, but no response. safc will not adjust fuel any more. reset ecu by removing efi fuse(NO CHG). all i have on the car is 780cc precision injectors,fpr,JE piston 040,Eagle rods' port polished head with crower parts, gt45r turbo,-6 in -8 return fuel lines,walboro intank,bosch 044 external,upgraded intercooler, 4inch exhaust. Really don't know the problem really need expert help.i use to be able to adjust fuel with the two pumps but not anymore. No codes at all
7mgte running rich

780cc?
hrmmm, to my knowledge, most people dont go that big unless they have a standalone as the safc has trouble adjusting for such a large injector. Attempt to lower your FP

in the dwn pipe. the wideband use to run right. i wired up a hks dli ignition and haven't ran right since. do you think when i disconnected the batt. it reset the ecu and the ecu have relearn the fuel map?

700?
youll never make that on safc alone, you will blow up your engine.
invest in a standalone

20psi at idle??????????? Surely you're speaking in terms of vacuum.
It does not take the ECU long to relearn. How long has this condition been going on. I would lean more towards something else you did, or a boost leak you missed.
