  1. Is there anybody out there?

    1988 I started out in VAG tuning, internet wasn't even invented back then! 2008 was when I signed up here on a last profile, 2011 this one, there were a few years of lurking before then! What got me into VR's was a black mk2 12v on the cover of either PVW or Golf+ - was before the 1.8T came out so that long ago! Amazing to see how far the aftermarket scene has come and the level of tech info available compared to the 90's! The old skool stuff like mk1-3 are getting a bit thin on the ground now like you say, you couldn't give that stuff away back in the day!
  2. list of cars that use the vr6 engine

    Holy thread resurrection Batman! Most of the ecu codes of the VAG 24v's just to add to this;
  3. There's a lot less interaction on the forums nowadays, not just this one - is everyone just facetubin' it nowadays or does that mean the mods have covered all technical Q's now? Just wondering what's changed in recent years?
  4. Smoke after engine rebuild

    What routine are you following for bedding in? Apart from that the usual is to check the working of parts added for running, wiring etc, basically all sensors, lines and so on.
  5. T4

    No, all are welcome, just generally kept to VR related subjects. I'm sure lot's of people can help with anything, lot's of technical Q's already covered in many threads over the years if you have a search 1st.
  6. V6 4MO 24V BDE Tuning

    Not sure if it was the BDF from the thread link above but just dug out some locations for the US lot; Check the cw but looks okay; Main locations for the BBSAWE maps; Your rpm limits will generally show up as B0 68, of which there can be loads, look at the spacing between them to narrow it down in your hex editor or most should show up in these locations as there's not a massive amount of data stacking changes twin vvt to twin vvt files;
  7. V6 4MO 24V BDE Tuning

    p.s. This includes BDF, major offsets with the early single VVT stuff like AUE which can be a pain to define comparatively and I lost the early ones I did on dodgy hard-drive and haven't done much since, but if I have time I'll have a quick look if you put a link to your oem file for me
  8. V6 4MO 24V BDE Tuning

    I did this quickly some time ago off an R32 file, I think it should be pretty much spot on but I'm reversing at the mo so time will tell. Seems to match up with mininuts file post but if not, pipe up and I'll try and dig out any address changes for you! Based on this post to read up on, can elaborate as required as/when needed if your addresses are off etc; http://nefariousmotorsports.com/forum/index.php?topic=7174.0title= Or I've got this full read to work off to do a better xdf/FI tuning etc if you want to get the file and are looking at long term?; http://nefariousmotorsports.com/forum/index.php?topic=17018.0title=
  9. What does all those turbo numbers mean?

    Some info in here at a quick look! http://www.volkspage.net/technik/ssp/ssp/SSP_127.PDF
  10. What does all those turbo numbers mean?

    Just quick links, not sure what data's available but a push in the right direction I hope; http://www.vaglinks.com/vaglinks_com/Docs/SSP/VWUSA.COM_SSP_871003_Wiring_Harness_Repair.pdf http://www.volkspage.net/technik/ssp/index2_eng.php
  11. Dual O2 sensors to single, how?

    You need to make about 2-300 changes in the ecu to have them running right without boost sensor, not an easy job! You need to do ignition, fuel (oem injectors pretty small for any boost but you can do all the 3/4 bar changes, return/returnless etc), fuel mass, flight time mani dep, throttle angle, air mass, torque, exh temp modelling.... list goes on and that doesn't include the set up/ecu configuration changes depending on what parts you're using - oh and dsg if your using that.
  12. Inlet maifold??

    Peak torque is shifted higher up on FI engines plus you have the forcing of air so short runners okay for that, but unless you're going for a very high revving engine (not really the best engine to do that on being undersquare tbh), then you'll be better keeping the stock manifold for more low end torque - depends on your goals though I suppose!
  13. Dual O2 sensors to single, how?

    Yes, generally made with lots of other mods as well just for normal fuel, na to fi is about the hardest thing you can do on Motronic, either on a flash based tune or the mods needed inc. custom coding and parts. There are a few ways you can go about it, best bet is to learn the basics on the Function Sheets online, things like BGSRM, BGRLP, BGAGR etc which can all have an influence on the relative charge, load, rpm's etc which is what you need to do. I've put up plenty of links to the various aspects but it can get quite complicated and depends on what you can do and how you go about it. I'll try and put up a basic overview to help those going through the 2000 page docs!
  14. Help: Schrick vs sp short runner ; vr6t

    Variable geometry (Schrick) is generally better than fixed as it is designed to operate more efficiently more often (i.e. various rpm's), you just have to think about turbo placement and manifolds where the inlet tract is/the packaging constraints, plus heat soak etc https://www.researchgate.net/publication/311615696_Effect_of_Variable_Length_Intake_Manifold_on_Performance_of_IC_Engine
  15. Dual O2 sensors to single, how?

    Making 02 bungs in a cast mani is generally the way many do it, emulates the big name tunes. The two ways are generally like those, manipulating the air modelling whilst taking into account the P/I portions required to a degree (rl/rpm/egt/evap/vvt etc) and forcing open loop, or alternatively running it like oem on closed/open loop and taking into account the PID, adding either simple custom PID routines or more detailed patches and heavily modding the electronics to suit - both quite difficult in their own ways. The ignition (KFZW) on these isn't too bad at low load/rpm, prob need to bump it up a touch around idle and low rpms (>2k rpm) similar to 2500-3500rpms range but slightly higher values (42-45 at low rpms/load, >50 ish at high rpm/low load), then bump the high load up throughout the rpms and a mix of higher values in the mid range. If you look at the various SU/LEV types of monitoring (ME7/ME9/MED9 for example dep on your car), they'll give you an idea of what areas you need to think about as well as air mass modelling for post ambient on a none map car if you're not hacking the ecu and can bus to bits! WB02 FTW also so use those gauges to keep an eye on the afr's!
