Hello! I have problem with my bex. Engine is after full rebuild, because i buy car with damaged turbo and head. I'm getting a lot of knock retards. I dont think is real knocking, because if i advance ignition from 12 degress to 17 degress, i always have same values of knock retards. I changed knock sensors with proper torque, engine mounts to ori Avon and gearbox mount to Lemforder. I make long 2.75 downpipe, but with same result. Clutch with dmf is too new from Luk, but i think this can be bad balanced (previus owner change it). I feel body vibrations on idle, body and gearbox lever vibrations when accelerating. Somebody have same problem? :o

Make a log with ME7 logger

I dont think is real detonation problem, because if i retard timing or advance by 5 degress, retard is always the same. Afr is 12.8 dropping to 11.8. Spec and acutal boost is ideal without overboost (max 20mbar).  Anything make noise for knock sensors, but i dont know what. I bet on clutch. Build is from my previous car where are all fine with max 2-3 cfs near revlimit and only clutch, gearbox and wiring with ecu is other.

Just post a log.

Read again, this is no detonation knock...  If i stun knock sensor and make more advanced ignition, i have 910 egt at 200 km/h and dont hear any knock with phones. Only when i run again with knock correction my turbo is pink glowing together with manifold studs and lost power.

ARMD, tourqe intervention?

If i have disabled torque intervention it possible? And do torque intervention make cfs on 020 channel?

Just. Post. A. Fuckin. Log.

No it doesn't make cf.

on which channel i can log fake noise?  ::)

Just post a normal log man.

Read again, this is not real knocking. It also knocking with 0,2 boost with the same retard values. When i have bent exhaust valve more boost or more ignition = more cfs. There is no matter ignition and boost, always is the same values of retard, always! Then stop asking fucking logs.

lmao

Then stop asking for fucking help.

solved, for "experts" its caused by bad timing belt damper.

I have the same exact problem on a totally different engine & car, just not as persistent, and so far was not able to pin down the issue. The auxiliary belt tensioner has been changed, have not gone as deep as the timing belt one yet...

The log discussion reminds of all the times at the dealership buying parts for my modded / engine swapped and turboed car, "Sir, we need your VIN number to be able to help you!" FFS.

Yes you solved the problem, I am glad you did it, but I have similar problem (my knock 3 Voltage is allways double higher than others) if I have your log i could compare it with mine...

But never mind, still you share a good information, i didn't know belt tensioner could make that problem

Also Look in block 93, there will be a correction factor there, ideally this should be 0, on 4 phase hall sensor , it knows how far your cams are off from the crank. It can be off by 15 kw or more.

Second voltage doesnt mean much, and the reason knock 3 is always higher is because of the block casting. Cylinder 3 water jackets interfere a tiny bit with the voltages, but these are properly mapped anyway from factory.

you mean if the car has ignition retard by bad fuel for example then it will glow the turbo and manifold?
Friend of mine has BFB with lambda going to 0,72 from 4500 to redline but turbo is still glowing. it has 5degr retard.

1.8t cant hold high ignition with lambda under 0.8.
