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

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

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 i

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 requeste

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

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.

Cam upgrades for 2.8 24v that pass emissions tests
RBPE replied to Doublestout42's topic in Engine Tuning
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 ex -
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 v

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).
-
What do you want to know? Most aspects have been covered on the forum so have a look through beforehand then ask away on more specific things!
-
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;; https://store.034motorsport.com/main-bearing-set-coated-vw-vr6.html https://www.ecstuning.com/Volkswagen-Jetta_IV--VR6_12v/Engine/Mechanical/Connecting_Rod/Bearing/ 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

How many oxygen sensors does a OBD2 VR6 have?
RBPE replied to LouieP's topic in Engine Maintenance and Problems
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 aw
-
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?
-
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 loo

Some info in here at a quick look! http://www.volkspage.net/technik/ssp/ssp/SSP_127.PDF

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

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.
