Title: erratic fueling Post by: Maddog82 on December 24, 2019, 03:23:20 PM Good evening one and all.
I'm having some issues with my fueling and I'm wondering if anyone can pass on some advice on how to correct the issue. I have attached some logs from vag-com, 001, 002, 031 (normal driving) and 001, 115 (3rd gear pull). as you will see fuelling is not very good, so any input would be super. my thoughts are fuel pump is not up to the job. 1.8t 20v fully forged bottom end Garrett gt2860rs forge 007 dv nortec 1.25" exhaust manifold 2.5" intake and boost pipes. 3" turbo-back, exhaust & cat delete 725cc EV14 bosch injectors large front mount welly intercooler STD fuel reg, STD map sensor STD MAF sensor STD fuel pump. many thanks and merry xmas Title: Re: erratic fueling Post by: Maddog82 on December 24, 2019, 03:25:32 PM also, you see there is a boost issue,
N75 works, and running 20-25hg vac with no boost leaks. 3 turns preload on the wategate STD 12psi garrett waste gate actuator Title: Re: erratic fueling Post by: Maddog82 on December 24, 2019, 03:31:56 PM BAM ME7.5 ECU
