Hi guys, I've installed ADR intake camshaft and GT2871 in my AUQ engine and obviously I tuned the ECU. According to my previous experience I changed camshaft overlap settings as following. Int: 1.0mm Ext: 0.7mm. To tell the truth I'm satisfied how the engine works and how much power it has but as always I want more power  So the main question is: does anyone has log files with non stock camshaft settings for stock or NA camshafts? PS the spool is a little late at about 4000 rpm and I want to try reducing overlapping maybe I'll find more earlier the spool with the same power at high-end rpm area. My logfile is attached. Regards. |

I do this moslty only on naturally aspirated engines, there is much potential if they were restricted because of emission-standards (nox-reducing), e.g. by internal Egr-Functions, or throttling to get more difference to a following model. My favorite example is the A8 D2 6.0 W12... Ori 420Hp, after reworking, removing Egr, and more.... 490Hp (no joke), still not the limit, but safe. Customer(good friend) was more than happy. Called me in the middle of the night to tell me that the car run like never before and new rs5 got no chance |

just get 2.8 cams and call it a day. The 2.8 cams have more duration and opening. Then just drill the cam sensors mounting ears and clock the sensors.

I take it by 2.8 you mean the 2.8 v6 engine?
AUQ is a 4 cylinder 1.8

1...The easy way for the 1.8t is to get a 16 valve adjustable cam gear and drill out the mounting ears on the cam shaft sensor so you fool the computer.
2....or learn the computer and properly adjust the cam shaft that way.
3.. do the research and find which 1.8t engines have the performance cams from the factory all ready
4. Buy performance cams and spend a lot of cash

The AUQ has VVT from the factory and it can be tuned to deliver more power over the rev range. Just never come across someone who has done it. The OP seems to be on the right track tho

Everything I've read says the vvt on the auk is only swung for emissions, but interested if you could use it for torque, if I get a clear day I'll log my rtech auq and see what they do with the cam angle, as that's a very torquey map.

I believe rtech offer a map that uses the vvt for performance and not emissions. In standard form the vvt is used during cold starts only but can be utilised

What exactly do you want to know? I adjusted camshafts overlapping with special tools. You can see it here http://postimg.org/gallery/39ygwnooc/ |

Have you tried to play with VVT? I've tried but this didn't give any reasonable results with my current overlap settings. And I came to a conclusion that VVT should be disabled. |

According to ME7.5 manual VVT is used during cold start only for cat warming. |
