It'll run without those.

It may not run with faulty ones though.

I placed my AA ecu, and I have spark on 4 plugs outside of the block, but when I fit them and crank I get no start but 4 wet plugs. My timing belt might be off 1 tooth, I pulled the valve cover today and found out the notch on the exhaust cam does not fully aligns with the cam sprocket marker. I may have set it to the wrong side when placing the new belt, since I could not get crankshaft marker and cam sprocket marker to align 100%. It did not interfere when I tested it 720 degrees by hand so I expect no damage.
Vagcom shows airbag fault code, and occasionally N249 and EPC warning light error. No MAF attached, engine temp sensor is attached now and is showing good values. Throttle is adapted and OK. It also moves a little on cranking, between 1 and 5 degrees I believe.
Vagcom shows timing at 4.5deg where specified 6-11? Is the engine picking up the cam offset in this measuring block or is it the normal value for a non-running engine?
I'm slowly getting there  I will properly check the timing later this week. Any other thoughts?

Didnt copy them, was working on my other laptop. It was only the airbag code implausible signal and n249 open or short to ground. Did not get any codes for my missing MAF or 02 sensors...
Tested cranking without cam sensor, no result (got a code camshaft sensor open or short to ground which I erased after). My next steps will be:
-recheck timing belt. If it is fine after all:
-check ignition timing compared to camshaft (that it is not on the wrong stroke)
-check fuel rail injection while cranking (hope I dont explode)
-check fuel rail pressure
then if all is fine I guess my spark is not strong enough to ignite, but that would be strange on 4 coils with new plugs at the same time...Or the plugs heatrange are way out of spec 

Thanks for that info, I suspected that so I hoped to clear the possibility my cam pos sensor was wrong or misaligned by removing the plug from the sensor. It did not affect the starting attempt. I'm putting my money on the timingbelt, even though I dont know if the sparkplugs would get wet in this situation... If its not the case, there is another defect, but I cant imagine the coils are firing in the wrong order or something like that.
**something crossed my mind real quick: I'm assuming the wet spark plugs are wet with flammable gas. I will get a fresh tank of gas to feed the fuel pump, who knows my tank has filled with water over time   I know that this gas what is inside the tank is at least 3 months old, maybe more. I always drove on LPG so maybe it has lost some of its flammability. I have never encountered a problem with starting on old gasoline though, but on the other hand I never had my car sit still outside for so long. Just ruling things out here. The plugs are certainly not wet from coolant, because the system is empty. If I have been attempting to start on some unburnable liquid, I will feel real stupid
***Timing belt was off by a tooth, cam was delayed. Checked for fuel spray, injectors fire in the correct order. It does not really smell like petrol around the car, but I did not have any more time. Tomorrow I bring a fresh tank of gas and place my other cars battery in stead of jump starting it. Spark did not look super strong, more white-ish and sometimes even a tad yellow (on wide gapped spare sparkplug though)

Custom stainless inlet piping, got everything hooked up now and just need to weld in a map-adaptor.

I am making a custom full stainless  2.75" tip as well, need to wait for the silicone adaptors to finish it. Untill then I will run the standard tip.

The cooling system is hooked up, had to make a T-adapter to replicate the oem coolant schematics with the reservoir on the waterpump inlet. I topped it off with fluid yesterday night, and tomorrow I will bleed the system.
and got a FIS speedo, a friend bought this for €25,- but couldt get it to fit in his car I'll find a way to fit it, they are cool.

v1 is finished, anybody that can comment? I have a checksummed version ready to flash, will be using a stock 150hp ecu (with just the 225maf scaling(which idles super clean at 800rpm)) and this version for logging, same base file (018AA,512kb)
Changes:
MLHFM scaled for 225MAF (also in stock bin)
LDRXN raised to approx 18psi with taper
KFMIRL adjusted 4 blocks to allow max load LDRXN
KFMIOP adjusted 4 blocks to match KFMIRL
LAMFA adjusted for max Lambda=0.80
KFZW adapted to 180 mapping as base for logging
KFLDHBN adjusted to max boost with taper for  70degC iat (mostly decreased numbers from stock file strange enough  )
LDRXNZK adjusted to max load=160 and 180hp values
ME7 Launchcontrol VNMX/DNMAXH/ITNMXH/NMAX/NMAXOG/TMOTNMX/TNMXH

*I am still missing some definitions, so there are maps that I wanted to adress that are not in the xdf. This is just a map to get started and experiment with tuning. Feel free to point me to important maps that I did not define!
Wont be driving this yet because I need to sort my gearbox and weld in 02 and MAP sensor. But couldnt wait to start tuning :-)

Current hardware to take into account:
AEB block/head
Full 3" exhaust, no cat, high flow silencers
3" MAF with K&N open filter into stock TIP (this will be a stainless 80-70mm TIP soon)
Ported wastegate K03-005
Twin 2" smic
Adjustable FPR but at the moment at stock

****
Tested the ecu today nov 20 and it starts, idles and rev limits at 4400rpm, according to LC function and with slight rev bounce :-)
****
Adjusted KFMIOP with interpolate exel file in version 018AA_v1a

I'm still working on my gear linkage, building v2 now. Less moving parts and should give a more direct control of the correct gears in the standard audi H pattern.
While working all of my powertools started to fail, so I started working on my manifold. Here are the 4 nozzles inserted opposite of the petrol injector seats:

Here with the injectors and rail connected, all equal lengths between nozzles and injectors and paired lengths between 1-4 and 2-3 injectors and rail.

Almost invisible with the manifold mounted on the car   These lpg injectors will outflow the petrol injectors by ~20% but probably the k03 is already out of breath before
