1.8t conversion. suspension and other bits

[Dan_GTi8v]

by factory management you mean 1.8t ecu and loom? would that just plug straight in or what? Im a bit ignorant to the electrical side of things, which is the main reason I chose to go with QPEng (that and I'm a lazy b@stard)

After speaking to LL about it, ive decided im gonna go

AUM engine with K03s turbo
02a gearbox from a 16v or G60
Ibiza clutch cable setup
ABF flywheel and a VR6 clutch
QPEng management
QPEng downpipe, which will need slight modification to fit a sports cat
FMIC Intercooler
16v magnex catback system

what would need to be changed in this if I wanted to go for factory management? I wont be modifying anything more than whats listed above so it should be ok without a knock sensor?

[VR6_Wherry]

I would advise a knock sensor, but i know LL doesn't run one!

Yep +1 I would whatever path you take run a knock sensor.

[Dan_GTi8v]

I was under the impression that you cant just add one though, its something thats built into the management? what can I do other than run different engine management?

some ecu's can run knock sensor, but the mbe 992 can't run one, hence why i don't have one. its not needed though if the ecu is mapped correctly, and qpeng's case they map it correctly and haven't had a problem with it.

This is what I thought, but some people have got me worried about what would happen if say I'm in the middle of nowhere with no petrol and dont have access to the good stuff

Wrong to say it is not needed, it may save your engine one day

With no knock sensor any detonation could mean a melted piston.

[Dan_GTi8v]

What do knock sensors actually do then? How often does detonation happen on normal engines

whats involved if I wanted to use the ecu from a 1.8t?

[AudiA8Quattro]

A knock sensor helps prevent pre-detonation. That is when the fuel ignites too early, causes the engine to 'knock'.
You can run without one, but as Wayne pointed out, if you don't then you are not protecting the engine.
Pre-detonation can happen even with a dud batch of fuel, so on a performance engine i would strongly recommend using a knock sensor.

DO IT ONCE DO IT RIGHT springs to mind haha 

gonna rock the standard S3 management in mine with a superchips remap, would like bluefin if they do that for the S3
