Hi All,
I think i've got some issues with my car...
Running rich.
LTFT has settled in the last couple of days to -5%, was at -10~-15% last week, avg fuel consumption now is 12-14L/100kms, normal would be 6~7L/100kms.
Pre cat wideband sensor generally is at lambda 1, post wideband sensor shows rich most of the time between 0.8~0.9.
HKS plugs are black, indicating running rich for sure.
Power Loss.
Had a Tork Stage 0+ put in, great fun for 2 days till the DCT slipped 2nd gear twice and since power feels down about 20%. Could be in my head but i could smoke the tyres from a standing start and launch hard, now car feels meager. Car still drives smooth now, no slippage at all.
Rough idle, had a fried comment that the car doesn't idle as smooth from one day to the next during a blind test.
As a precaution stock tune has been loaded back in
Identified some bad clamps on the charge pipes which have been replaced, boost leaks all gone now., will confirm shortly with smoke tester.
Fuel Pressure.
Anyone know what the stock fuel pressure (PSI) is at idle? Torque is showing ~560PSI at idle.
I'll upload more data when i can.
Thanks
Dan
