  1. Bunch of parts that have turned up this week for sorting stuff out on the car... A pair of brand new TRW rear calipers (with audi logo's as they are an OE supplier) that cost £35 each in the Autodoc Black Friday sale.... new pads for the rear (just std Brembo jobbers), Mintex M1155's for the front, new rear brake lines, RBF600 fluid, brand new aircon pump, brand new aircon dryer and a cabin panel filter Just need to find the time to do this lot lol <tuffty/>
  2. Grabbed some time in-between playing BF 2042 to hook up the wiring for the vac pump MAP sensor... Added the senor input to ECU pin 11 as a User defined input This then popped up the relevant menu item in the sensors section and scaled it to be the same as the main MAP sensor (they are the same 3bar sensor) ....and took a quick trip to Mexico to get some data and also to check the coolant temps now the CFS rad is on... Obviously the main fix to the brakes was fixing the split pipes and ultimately the vac pump is more to support the
  3. Thought it would be a good idea to crack on with sorting the brakes as it seems a fairly good idea for a 1.5tonne 500hp car to have some Made up the loom for the vac pump... Routed the cabling through the main loom to pick up where I had wiring for the second MAP sensor I had originally planned to use for the Color MFA... ...and spliced the MAP wiring in.. The sensor wire is already next to the ECU so I just need to add that in and configure the input to be able to see the vacuum in the servo line... I have not done that
  4. So here we are again... front off the car to sort out some the 'minor' problems of the aircon pipe and charge pipe clearance.... The aircon pipe needs to have a straighter exit from the back of the pump as its current angle means it just goes straight into the fan... ...a bit of tactical persuasion later.... Yay!... I then slotted the fan pack mounts a bit so I could lift it up a little higher to gain some space for the charge pipe and reassembled the front end... with a bit of jostling about of the clip mounts I got the clearance I needed
  5. Didn't feel like I got much done today but progress is progress.... First up was to address the power steering 'cooler'... the S3 one that loops around the front of the engine forms part of the return circuit for the PAS... on most 1.8t's the return goes from the rack and straight into the fluid reservoir but on the S3 and other K04 turbo'd 1.8t's there is an extra loop for additional 'cooling' capacity... this pipe ('L' shaped) was not fitting too well as it was with the VR but now I have changed to the 4-motion PAS pipework its even more in the way (although as it turns out the 4
  6. I have taken some time off work to get the car into a drivable state... fitting the CFS rad and keeping the aircon has been a bit of a challenge and that challenge hasn't ended yet!... When trying to secure the slam panel properly it was evident that some more modding was required... first task was to mod the slam panel itself.. this required a couple of cut outs to allow the repositioned dryer canister to 'fit'... (it's still jeffing tight!!!) Once done it allowed the rad pack to fit properly into the slam panel... offering it back up to the c
  7. Bill has kindly given me a corner out of the crappy weather so I can do some work on the S3... CFS radiator, vr6 PAS pipework and the fuel rail plus the vacuum pump will be going in over the next couple of weekends... I had an issue with one of the GSF fans (new at the time of fitting the VR6 in)... I had been getting quite a large vibration from the fan when they were on and turns out that the larger fan was the culprit and the blade assembly had come loose ...so a bit of locktight later and it (and did the smaller fa
  8. Small update on progress and ongoing 'projects'... The charge pipe got some tabs welded on so that I could make a support bracket to hold it in place As ali is notorious for stress fracturing from vibration I decided to use isolating bobbins to try and mitigate that... Added and extra strap to help with support... I still need to make a second bracket for the other tab but as yet not had the time to work out where that will go as its a little less straight forward... but will update once I have done that.. Obvi
  9. All going well so far... have done a few more bits and bobs that I plan to post up about soon... just waiting on parts as per usual One thing that did take me by surprise was the effect on the coolant heat... I know that VR's tend to run a little hot anyway but even when I had the 20v in at 620hp the standard rad and cooling setup kept that at 90 degrees all day long... but for whatever reason if I go for a bit of spirited driving the water temps get to 100 (have seen 104 deg in the logs) pretty quickly and of course as I still use the oil/coolant heat exchanger the oil temps star
  10. Bit of progress with DSG related stuff.... After a bit of deliberation I acquired a different DSG selector... this one is from a Polo 6R (2011)... this 'should' work fine and is the same as one used by a friend of mine on a DQ500 gearbox.. it being from a 7spd vs 6spd should not make any difference as all it does is tell the gearbox what drive mode to be in or in manual mode to change up or down... My mate has retained the Polo knob and trim but its not the best fit... so I bagged an S-Line version... The other real difference on this selector s
  11. So this happened!.... Initial run off the back of my tuning trip in 'Mexico' netted 485hp... this was at a shade under 1bar as I needed to tweak the imax up a bit for it to achieve the 200kpa request up top... Had a couple of runs just faffing but it was evident I was running out of spring rate in the wastegate as raising imax was having diminishing returns on boost... For the final map I bumped specified boost up at the top end to 210kpa as I was seemingly stuck at 490 odd hp... Boost map ended up as... ...with integrator
  12. So while I was in 'Mexico' it seemed rude not to enable the N75 and build the boost map First iteration was to get to 180kpa or 0.8bar/12.6psi from my actuator pressure of 0.5bar/7.25psi.... Set the 'P' of the PID control to 0.1 from the map file wizard settings to give a bit tighter control... Then set the limp mode over boost threshold to 185kpa ...and finally as an added safety I set the over boost throttle limit to 30% at 200kpa in the egas throttle modifiers On to the boost map... top line is 180kpa w
  13. For the past couple of days I have been in Mexico pretending to be a 'tuna'!... VE map is in a happy place now for actuator pressure and trims are looking good... Next up.... N75 controlled boost <tuffty/>
  14. Thanks all... been a fairly intense week... my arms and hands look like they have been mauled by a hundred cats and my feet feel like I am walking on gravel bare foot... but... its been worth it.... Yesterday started off fine... not knowing when the flexi would turn up I turned to plan Z... use the flexi from an OE drain I had... After quite a lot of faffing about Franken Drain was brought to life!!!... Happy with myself I went to grab some lunch and as I finished that a delivery arrived... Well fark a duck!!!... so oil drain v2 or t
