So just to clarify, have you modified your ECM with non VW software?The TCM fixes 20 to 25% of the problem. The MPG's are still 10% down, torque is waaaay down too, at any throttle setting. The other real fix is the ECM. That makes the car run the way it should down the freeway or interstate, the way it was when you bought it. TCM is but a small part of it, it needs both fixed.
Volkswagen wrecked the drivability of the car, it's no longer a SPORT SUV, it's a utility grade of SUV.
From experience.... I'd get them both done at same time. ECM is 80% of the fix, TCM maybe 20 to 25% of fix. If money is tight, get the ECM flash first, and shift manually. The ECM makes the car drive the way the Germans engineered it, in the first place. Which is to say, it would reinstate the all the torque lost at lower throttle settings, which makes for a piss poor driving experience from a TDI.
They modified the shifting behavior to help warm the engine up faster and to reduce emissions.First thing is, VW/Audi changed the TCM with the fix for a reason. Why?
Gassers have different power bands..... they typically make power later in the band, up at higher revs.... you need to wind them out to get the most out of them......Any finally, I see a lot of people talking about it shifting like a "gasser" and that being bad. What is bad about that? I've never had a diesel vehicle. And why would one desire engine braking?
Yes in person flashes save you time on the waiting listHi, I'd like to get your TCM update and live in southern CT, so I could stop by sometime if that makes things easier as my unit could be updated in the car (I hope/presume). I do not have enough posts yet for a PM, so could you please let me know your schedule and how best to contact you. Thanks very much.
Since i've been away and your post here is rather old and I have relied to your multiple emails and various questions that you have emailed me about. This unfortunately takes time away from me answering other people, and working on the performance tune, etc...Hey guys,
I got yrktreg's fix in June this year. I appreciate the work Joe has been done to try to restore the TCM software; dont get me wrong but I truly believe that it is room for improvement. I have A 2013 Touareg.
I am not sure that it is an original restore since it shows another version. It seems to be a kind of tuned VW fix software.
Joe (yrktreg) never answered my emails when I asked for more information.
I asked him also if he has the original TCM software, no answer yet, I know he is busy. I will wait.
I would really love to have the original software, I will deal with warranty here in Toronto myself.
Your version number shows the same as the fixed version so that you do not have warranty issues, this has been covered many times.
Here is the situation after I drove the car with yktreg fix for two months:
- shifting 1-2-3 should be fast and at low rpm maybe around 1500 rpm like in manual mode - is not happening, shifts at 1800 rpm and slow, gasser kind of shifting. NOTE: If this could be fixed, the car would feel and be fast.
So I am supposed to make you a CUSTOMIZED tune to the transmission shifts the same as you do in manual mode? I can do that but you will pay much more for it. It shifts at 1800 RPM because this is where the peak torque is. Research this and you will understand.
The 3.0 TDI produces 400 Nm (295.02 lb-ft) of torque between 1,250 and 3,500 rpm so there is no problem shifting at low rpm.
General impression is that overall seems better than having shifting at 2500 while cold (that is the only benefit, I feel), but if he can address the issues I am talking about, that would be great.
- there is no 2'nd gear engine brake, like the VW fix version.
- 3'rd shifts two times,
- if you get to 4'th then all seems ok, like the vw fix.
- sometimes is jerking in 1-2 or 2-3 shifts
I would like to know what you experienced.
All the best,
