I was wondering if anybody has ever seen an issue like mine on my boosted R32. I have an HPA 7670 Turbo kit with a custom front mount intercooler setup. I have united motorsport 550 software on the stock filter/4 bar regulator returnless system. I have boost leak tested this engine up to 25psi and its solid. Compression test with an 8:1 spacer was 145psi across the board. Leak down test was done at 80psi and only leaked down 2 psi on each cylinder. My fuel trims are being crazy. While cruising they are between +10 and +25 and at WOT they are maxxed out at +25 and my air fuels are borderline at 12.8:1 in some cases…. Fuel pressure is great holding 56psi at wot. Not sure what my problem is considering no leaks. Ive swapped mafs and o2 sensors out and no change. VCDS says my ect sensors are reading correctly. I am chasing ghosts. If anybody has an idea of what could be wrong let me know. Thanks
The maps not had a single o2 patch on it by the sound of it, much like HPA's ones, hence why the pre-cat bosses are in the exhaust mani. The ecu often gets confused by the readings and tries to compensate through learning, eventually leading to severe drift.
FI maps on these can be quite different, if you're not using the turbo kit and fuelling/map that was developed with the kit then you need someone whose dealt with them before to retune it or modify it. I know Stealth have dealt with retuning these at times and ive done a few but no longer work in cars atm. So they're your best bet but its likely that, you can find some o2 patch info on the forum, how are your o2's placed etc.....plus one company's map can be very different to another's!

No worries, I intend to build up my own correct full defs anyway as I'm deleting loads of old files, I'll just add bits and bobs when I can, will try and dig out a few maps for other such V6's as well.... so here's a couple of screen shots of some BDF locations, I think it is just an 032DM file someone's stuck up on Nefmoto - should be similar to other BDF's - your speed maps are of a similar location to BDE but some are different values if I remember correctly. Don't have time to reverse a US one, sorry.
You may want to make a copy of the screenshots as I may delete the pic file in future -I'll prob put up a big def folder link when I do though.
Should be correct locations on the 032DM file:
ignition area to see (note that I've added a Nef BDF & it seems to have a slight remap, not sure if the values will be the same on your stock ones but you should be able to see the same/similar layout of the hex if you 8bit FF it like I do.
I'll plod on adding bits as and when, to build the major locations of the 2.8 24v's as best I can at least if you need to tweak your ecu or disable something. I think someone's building an xdf publicly on Nefmoto so you can literally just use that and add locations in future or vice-versa.
-
UPDATE: Sorry I've not posted anything, been out of the car game for a while now.
Tunerpro was buggy for me and I don't need to use it so I didn't piddle about much with it.... but I'm patching together a big, correct BDE def so I've got one to hand and I'll put up pertinent info as and when I can.
The 032CN file on the net is quite good for picking things out but it can be a bit off - like the ME7.5 20vt lot, you'll get incorrect defs and all sorts which is why it takes time to make sure it's right, plenty of reversing etc.
*** I'm using the file I requested off Nefmoto in the link earlier by the way so it's easy to back-trace too in future - they tend to always have the data in the same area these BDE 032BG files, just some differences in data prob due to market/legis reasons.
So, the areas for making your own pops/soft launch, higher speed limits and rpm's;
Here's what I mean with the data not stacking up correctly/def files used being off etc - LAMFA - a common problem many 20vt def file builders get;
Your codewords should be around there - check the 032cn file in ols to find out what they are or I'll update in due course; (**slip of the pen only on the 00/01 being on/off if it confuses you!)
BTS:
KFKHFM/ESKONF:
I'll add the data areas I've just defined below, they should be correct but I've got a few things to check like here, ancilliary (compressor) torque. Probably irrelevant but if you go FI and you're dealing with; pedal/throttle angles/flow/charge/torque management/inlet mani etc as well as start/after-start/idle etc, it's best to have it all to hand really! Plus, def/calibration files are pants usually for these!
Compressor/ancilliary torque areas around here at quick look; (just notes for me when I revisit this);
So - locations I've just done in last few hours on your BDE 032BG should be;
***** I might just have this thread for xdf/def file building for now and we can go more in depth on tuning/DIY tuning at a later date. Assuming theres interrest of course as I have no need to do this anymore really and everyones FaceTubing it nowadays?

Actually sorry - to clarify - this was in relation to the W8 using ME7.1.1. not even looked at the W12 tbh, was thinking W8, but if it's ME7.1.1. too then above applies. If not, then technically it still applies anyway as it's just configuring what sensors/inputs/outputs - same as any project really in that respect!
Easy way to think of it - look at the ME7.1.1./W8 SSP in the link - it mentions some differences to the R32 ones in there/part changes etc. Also, other easy way to think of it is - if you de-cat, then the reading the ecu gets will not be oem due to the expected changes with a cat than without. You can tune your car to run right - may take time and you may still have a fault show up, or you can simply configure the ecu to think it has no sensor after the cat and bypass the strange readings, or in some instances, a mixture of the two, easier than doing lot's of tuning and still be tuned right.
Either way, if you do a big project, use as much of donor bits mentioned above to save a lot of money and if you can use all/most of the electrical/ecu realted gubbins, then it needn't cost a lot to sort.

I think I found my answer Haltech.com R5 VCU.
More conversations wth them but 'sounds good', so far.
Philly, thanks for the warnings. There is never enough money or time. Been down similar rabbit holes.
Imagine a 12 cylinder midengine Karman Ghia?
Bulging bodywork to cover Porsche Turbo sized tire/wheels. Speedster like windshield? Basic idea. I have a couple other ideas for it.
I do have a line on a complete VW Phaeton $5,000usd.
Sorry I am in the states. Your club was first up that I thought could help.
I will let you guys known when the project starts.
Thanks for the replies
I did help! Told you the easy way to do it but you seem intent on over-spending! 😉
Get donor car - use ALL or AS MUCH as possible in - ecu's/wiring/sensors/clocks - basically the electrical bits - configure as required (any half competent Motronic specialist if you're using the oem stuff) - done! They use a lot of the same parts in terms of inputs (sensors), it's just the dual bank/master-slave engine and ecu config - nigh on impossible or far too expensive as it'll have to be custom written/sniffed lines etc - all negated if you are using a donor and associated parts really.

Lot of money for a burble sound! You could at least refresh head parts if well used but mapping needed and so on, hundreds at least.
Get a cheap (but latest me7.1.1 compatible) clone ecu reader, read your ecu, plenty of defs on nefmoto (may need to post a few times to see them though), BDE maps should be around here for soft coding;
http://nefariousmotorsports.com/forum/index.php?topic=17018.msg131846#msg131846
Theres other threads on hard coding, me7 very similar- so £50 outlay you can have it popping how you want with a bit of graft without the need for expensive hardware that yields little gain. (Plus you can sort the nox emissions with some fine tuning so it poops out little bunny rabbits 😉 )
-
12 injectors not 6 so you'd need to go through all the output system (ESKONF) there, any displacement/ cylinder differences inc airmass calcs for fuel...plus it runs a master/slave system for the other bank so you'd have so much to do there on sniffing lines so that everythings talking to one another properly....and so on.
Crash damaged w12, can use most/all ecu/wiring parts but immo off will prob be same as any other me7.1.1., speak to a tuner that is a winols customer and buy a def file off them for a few hundred quid and then build your own tunerpro file to tune then log with vcds assuming the system's are talking properly. It'll prob be same tuning basics as 24v vr, so not a massive amount of gains NA, but it's the configurations thats your problem.
-
Why use MSnS? You planning on tuning it yourself afterwards and don't want to use oem ecu? It's NA from stock so no boost controls and the speed density aspects are probably a little different than most are used to on aftermarket stuff on the Motronic (GGDSAS/EFGE).

The US seems to have catered for a lot - so good market there, ironic given the lack of good 24v 4wd options we EU/UK (as below) enjoy! But;;

Many EU/UK (cause we're not the same now
), ones can supply such parts (dying market) - but the money's in more modern models, few options either way in EU, or domestic VAG specialists will offer the same as EU re-sellers but it's more modern machines which pro's cater for as that's where the money is, still options - eg;

Hope that helps!

Follow the link I put up in the thread below, enter your model details and you'll see what parts are on your car;
-
It's usually some high mileage hardware wear and tear stuff like you've mentioned - but did you have it remapped after upgrading the cams? I'd keep an eye on all the oil aspects on older vehicles, had dodgy oil pickups/blockages etc destroy engines, even forged ones!
Did you do anything with the bottom end?
-
Ignore! Sorry
-
You can get a few hp with better airflow easily enough, ideally you want to tweak the tune any time you change either air or fuel although there are some good adaptations in the ecu's
-
More air would mean it running leaner, could be a leak somewhere or adaptions going wild over-compensating - older mafs can hate turbulent air - need straight piping sometimes at maf.

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!

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;
-
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
-
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?;

Hi all. I have an ob2 mk3 vrt that I just got an apexi acvr for and I am looking for wiring info. Can anyone share them with me? Thank you!
Just quick links, not sure what data's available but a push in the right direction I hope;

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.
), ones can supply such parts (dying market) - but the money's in more modern models, few options either way in EU, or domestic VAG specialists will offer the same as EU re-sellers but it's more modern machines which pro's cater for as that's where the money is, still options - eg;
Just wondering what's changed in recent years?
3.2 VR6 Turbo Fueling issues
in Engine Tuning
Posted · Edited by RBPE
Ah okay....I'm not sure what this "fix" patch is like but it sounds like it has the single o2 patch. However, the hpa stuff tends to be very much air based and so would need quite a few mods or just a complete remap really! Anything like different inlet manifolds/with or without the change over function, maf sizing, even the injector flows are scaled to the relative air mass and as such, I'd assume every remap would need to take these all into account really.
You ideally need to talk to UM and find out if the "fix" corresponds to your parts etc. Anything like a miss-matched sized maf/hfm will obviously throw the fuelling out!
It may just need a remap to tweak the fuel given the changes in map structure but it's likely all related to that if you've eliminated all the hardware/leak side of things. Also check the return/returnless side with them as most go mk4 and zero the map out - like I say, only UM can tell you what they've done.
