So instead of actually working out where the issue is.... You have bodged it? And this will likely be the reason it's in this state in the first place.

Hardly. But what else do you suggest so it's not 'bodged?

Timing marks bang on between the belt. Exhaust cam marker lined up to the cap. 16 links between the chain rollers on inlet-exhaust cam. Inlet cam markers line up with the exhaust side when the plunger on the tensioner is fully extended.
Care to tell me where it's out?

Dunno, I'm not with your car. But the fact is, you have something wrong. Have you tried a brand new vvt solenoid? Have you tried putting complete stock software back on the ecu to ensure something is not a miss with that? Have you replaced sensors? Have you checked wiring with a speccy to ensure no issues there? Is it possible the cams themselves are defective causing everything else to throw out. It goes on and on.......

Bottom line is, it would be very wise to work out what's wrong before progressing as it will likely cause you other issues later down the line.

I've seen the woodruff keyway break off cam sprockets. The bolt is tight enough to keep it from spinning, but they shift. Might be worth a look. |

A few good ideas tbf. I've just swapped out the ECU because my baro reading was 500, not 1000. Replaced ECU, fault goes away. Could be software too, why not try the original file? Could the ECU be wanting to see a different pickup wheel? I don't understand why it's so out though. I'd be amazed if the cams were defective though. I've seen the woodruff keyway break off cam sprockets. The bolt is tight enough to keep it from spinning, but they shift. Might be worth a look.
That's a good idea too! |

I tried a tensioner, and was still the same...could try it again now I know this setup shows 0Kw on block 093.
A tensioner is £480.....a bit much to be testing stuff.
Will set timing maps bcak to stock and do a log then see what it shows on the VVT changeover map...then back to stock on both.

Perhaps you have one of the other 1x1 or 1 dimensional cam maps out of whack on your tune.
Can you post your tune .bin and the ori .bin?
I've been spending a lot of time lately mapping out previously unknown cam timing maps on both the 3.0 and 4.2 N/A engines. Maybe I'll see something that you overlooked.

The issue is usually the chain stretching.

Don't bother. The focus here is far too narrow. Ignoring the 5 degree discrepancy in the middle of the fucking pull and instead focusing on an area that means jack shit. |

In a fashion. Had another lad with the same problem running a thinner Headgasket and a skim and his were -9KW and the timing marks bang on perfectly. So god knows what it is.
