So after all the mishaps, the car is ready to go and is booked in for Friday. Can't wait to have it all finally sorted.
Finally. Mapping on Friday

Good work mate, I know waiting to get a car mapped can seem like an absolute age! . . Where you heading for mapping and what sort of figures you hoping for?

Joe Power.
@vag slag.
I have a figure in mind. If I got in or around 340hp with the same in torque I would be very happy. But we will see tomorrow.

So the results are in for the moment.
306bhp 325ftlbs
Thought I had solved all the issues, but guess what I haven't. There is still something vibrating somewhere which is causing the knock sensor to pull timing. cyl 2,3&4 are hearing noise, 4 being the worst. Timing is at 4.3btdc so there is a lot left once I get it sorted the problem being finding the issue. If anyone has any ideas let me know.

Someone suggested, could my problem be clutch related/worn out dmf as that is the side of the engine where noise is being detected, as I had already checked everything else and cleared the downpipe which was rubbing before. I just cant think what else it could be and is really starting to annoy me now as his is 2 mapping sessions that have been f***ed by it.

did joe stick some octane booster in to confirm the CF the knock sensors were reacting to was real det or mechanical noise. Idead being if it was mechanical, adding some octane would make no difference to a mechanical noise.
Water temps low?

Don't know about temps and I think he lowered afr's to 10 and ran no boost to eliminate detonation where it still pulled timing. I know he did not add octane booster. He deffo said it was mechanical and not detonating.

If it's mechanical then the noise will be there regardless of boost. So if you ran the turbo on actuator pressure only and you still see the same knock voltages(not cf) then the sensors are picking up mechanical noise..
Sensors done up correctly?

Knock windows are worked out in production and set in KFMAKR and KEMLN.
These are independent of actual voltages seen because the actual final cf value and timing pull is based on load/ rate of change of load( KFELDY) and rpm(KFENDY) .. Therefore any mechanical noise say from a clutch will be there regardless of the actual load on the engine,
My point is,, you can have the same knock voltage at x rpm and very different cf values depending on actual load(boost) rate of load change and the rpm it's..
voltage is voltage... cf is factored

maybe I should have been clearer Dan..
Windowed "from" voltages is CF
that makes more sense reading my previous post.
That or the sensors are over tightened also... and wiring issues also bring about apparent voltages creating phantom CF

Will do. I think the dmf is on it's way out also so gonna look into changing that out at the same time.
