Yeah I need to get it fitted tbh. Looks fairly simple...apart from that passeneger side front bushing bolt. Did you completely remove the gearbox mount @r5gtt and did you jack directly under the gearbox itself to raise it? Were both front wheels in the air? Any tips for this?

Got an MOT done yesterday. Passed with no advisories which is great considering the decat etc.  :evilgrin:

yeah that bolts a nuisance tbh but not a long job to remove battery tray unless you have a stupid air filter shield fitted  :doh:
You need to move the black wiring harness out of the way toward engine to access three of the 16mm bolts and then pry it barward to access the last one. Leave the mount to engine three on. You will need to raise fairly high and better to have the both wheels up or even better all four innit a ramp so engine doesn't move and you struggle to put the mount back in.

As the current map on the ECU didnt seem to account for the turbo that had been put on to it, it ran lean - k03 injectors, sensors etc. So having bought all the fuelling hardware plus a few extras for the k04 it was time to send the ECU to R-tech to load a k04 base map on to it. To unplug the ECU from the connectors you need to remove the bracket which is held by four anti-tamper bolts (2 smaller and 2 larger). To remove them you need to cut a slit in the head of the AT bolts to get a screwdriver into.



Whilst the ECU was away, the k04 injectors, rs4 valve, 200bar fuel rail pressure sensor and 3 bar MAP sensor had to be installed, so that when the ECU returned it would run correctly. I had already rebuilt the HPFP with VIS stage 1 internals which are required for running 130bar. As the manifold had to come off to install the hardware I might as well clean the valves as well as installing a runner flap delete kit from AKS. Manifold off:



These were my valves at 62k. Probably be the same again in 15-20k! Perhaps a proper PCV delete and meth might help prevent build-up  :evilgrin:



Half way through cleaning, time consuming process. I used nylon brushes with a drill attachment, petrol and carbon cleaner. I used lakeland stove cleaner which is really strong stuff. You cant leave it in there for too long!



Inlet manifold with RS4 valve, 200bar fuel pressure sensor, runner flap delete with new inlet manifold and throttle body gaskets.



K04 injectors installed back in the cylinder head. I bought new injectors so the teflon seals, washer and the blue o-ring that sits in the fuel rail were present but I had to get the locator clips from AKS which come in an injector build kit.



After putting it back together, I primed the fuel pump a number of times and turned the key a bit nervously! It all fired up ok and after a short drive appeared to be behaving well. After putting my foot down it all seemed great - big smile! And this is just the base map!! After logging I was pleased to see the engine is no longer running anywhere near as lean as it was on the previous map, with lambda now at 0.79 opposed to 0.9. Fuel pressure up to 130bar so the HPFP and injectors seem to be doing their jobs!

Pesky jones:
Well, what a difference. She's an animal! Worth the wait... Now just have to save up some pennies for the full custom map! And bigger brakes needed @Dan_FR  :happy2: Thanks to Dan for all the help along the way!

AJP:
Good to hear it's running properly now mate. I've got to get a k04 some day!

Pesky jones:
Thanks mate. Im very glad its running nearly properly as well! Few little niggles. Main one being that the DSG map is still the previous sh*tty Uber tuning map, whereas the ECU now has the r-tech engine base map so they dont talk to each other very well. I can't wait for the DSG + full custom map!!

My girlfriend said Ive been in the car more in the last week then I have the entire time I owned it beforehand  :grin: :grin:
