Turn off red LED around RPM gauge?

[Upstate Audi]

I had my TCU tuned earlier in the year with the HP Tuners MPVI2. Among other things I had the shift point raised to ~7200 RPM. Even though the shift point has been changed the red ring of LED's around my RPM gauge still goes down to 6400 RPM. Does anyone know of a way to disable the LEDs from 6400-7200? It has never really bothered me but its on my list of little things I'd like to take care of.

Your APR tune didn't modify them?

[blackout85]

I don't know how. But I do know it's not done with the TCU. I had mine done with the ecu tune. If you have a tuner that did the ecu, they should be able to.

No... should it have?

My tune is through APR not a local tuner.


Would it be possible to do with a VCDS?

This theme has arisen in couple of threads in the past few days and I would also like to have clarity that is it possible to disable the LED’s to match the limiter on a pre-facelift A6 3.0T? I also have APR SP tune and I asked APR customer service about it and they said that they don’t do that.

Not possible with VCDS. Has to be done with ECU tune, ECU controls the rev limiter and the cluster LED red line. TCU controls the actual shift points.

I have a pre facelift,13 a6, and I also have mine showing at 7600 but with an IE tune.

[janhe]

Okay, thanks! So definitely possible. Any APR tuned 3.0TFSI people about who had their limiter LED’s modified?

Yes, just flashed APR stage 1 on Friday. My LED shows the Rev limiter at ~7500 now.

[janhe]

Thanks! Think I’ll need to contact them again.

Look at my avatar.

[Upstate Audi]

For the people that had their LED rev limiter raised with an APR tune was this with a 3.0T or 4.0T? And also did you have to ask them to raise it or did it happen by itself?

[wootwoot]

3.0t, didn't have to ask for anything special it was included with the tune

[Claccio]

Yes, just flashed APR stage 1 on Friday. My LED shows the Rev limiter at ~7500 now.

I had my APR stage 1 done on Friday too, but the red light did not move. Still 6400. Do you have any other time? Mine is stock except for stage 1.

Went from stock to stage 1, no other mods. The only difference I can think of is that my car is MY2016 so it's a C7.5 with the CREC engine. The ECU is different for CREC engines.

Mine is C7. So maybe that is the reason

Mine is also a C7 so I'm wondering if that could be the reason. My stage two flash was also done around a year ago though so I wonder if there could have been an update that changed it between then and now.

[WatchMeSpend]

MY 2016 A6 3.0T CREC
Stage 1 APR moved the redline.
Stage 2 Dual Pulley, redline is the same.

[janhe]

Bump!

So, do we close the case and determine that on pre-facelift APR ECU tune doesn’t change the LED’s on the RPM dial and on facelift it does?

My 2016 is in today for APR stage 2 sp so I'll have another data point to add after I pick it up tonight!

APR stage 2 single pulley flashed on my 2016 yesterday, shows 7500ish redline now

[janhe]

Nice, thanks for the update! Feels like a different beast now? :)

Calling for all pre-facelift APR tuned 3.0T owners to chime in! Where’s your redline at?

APR tune did not change the displayed redline.

Sure does!

[paul-g]

okay did stage 1 apr, redline moved but car shift at stock 6400 rpm. Called APR and they said "we know" and "nothing you can do". they don't control shifting points you will need TCU tune to change that. so technically on all they adv. they are cheating you out on 20HP cause they all show their making their HP number at 7,200 not 6400 and if you follow they graph it will show you it from 6400 to 7200rpm you lose about 20hpish and tq

[joserod92]

My 034 tuned a6 shows 7600 rpm redline in the tach, only revs to 7200 tho. mine is a 2012 3.0t

[janhe]

Thank you all for your contributions! Keep ’em coming. So, possible on pre-facelift too, it seems. Although it looks like APR doesn’t do it on pre-facelift.

Would be nice if somebody from APR could comment on this since they seem to lurk on this forum too.

[Delfin]

When I asked APR customer support, here is the response I received:

Thanks for checking in with us. Most platforms that we cover both ecu and tcu software will see that increase in rpm. Since the A7 doesn't have TCU software options here in the U.S., it won't raise that limit. Another companies TCU software may raise it but I wouldn't be able to confirm compatibility in changing the display with our ecu software.

[janhe]

But with facelift 4G the limiter on the gauge is raised by default although APR doesn’t offer TCU tune for that either? Unless you have S-Tronic of course which I understand isn’t the case in the US A6/A7? So confusing on their part.

I thought when I ran the numbers it was more like 40 hp. When you get a good AMAX shift it seems to pull a bit higher or sometimes when I stomp on it at about 3000 RPM in 1st and pull the paddle just right it seems to pull a bit higher and it is very noticeable. Looks like a TCU tune really unleashes the beast.

[WatchMeSpend]

My 034 tuned a6 shows 7600 rpm redline in the tach, only revs to 7200 tho. mine is a 2012 3.0t

Like p3u says, you'd rather have the trans shift than hit fuel cutoff if you want to avoid issues.

[joserod92]

my trans file is set at 7200. I believe they to this to accommodate for different trans files and not change the ecu tune to raise or lower the redline.

The TCU tune can't update the LEDs around the gauge which is why APR updates this through the ECU flash.

[janhe]

Yes, I’m well aware of that. My point was that APR doesn’t have TCU tune for any US 4G but still the LED’s are moved on facelift and not on pre-facelift so it’s weird to appeal on the lack of TCU tune.

Actually read that APR reply again and still don’t understand whether they are talking about the actual engine limiter or the LED’s indicating it.

Well, I’m also again discussing with APR customer support and now they tell me that pre-facelift tacho is analog and facelift is digital so that’s the reason why the LED’s won’t move with ECU tune. :D

The actual engine limiter is raised by the APR tune, it is just the LED display that isn't. TCU tune allows making use of higher limit in "D" and "S" modes. Never tried to see how high would rev in "M" before getting TCU tune.

Not that I want to throw stones, but if they say it doesn't move because it's analog, how is it that mine changed using IE? Sounds like they are trying to feed you BS because either they don't want to do it or don't know how to do it. This is just my opinion though and could be wrong.

Yes. I have S-Tronic and TCU software and the limiter is behind factory redline which is why I would like to see the LED's indicate the actual engine limiter at the moment.

Exactly my thoughts also. They also said that the pre-facelift software was initially developed for S4/S5 where the LED's on the tacho were not present. I think they just don't want to revise the software. I'm sure they know how since they made it work on facelifts (and other tuners know how). Oh well...

I wonder if other tuners might be able to change just the LED's or is it so deep in the engine management code that you need the whole tune?

[got_boost]

Basically they are charging a premium price,magically they lowered all the prices though so business must be slowing down with the competition, and selling a generic tune that fits all the older gen 3.0.
I'm not a tuner so I don't know what the coding looks like but if they figured out the facelift, I'd like to think pre-f should be in a similar area? So in my eyes,they already got everyone's money so why spend the little time to make this adj.? Unless they did it then found out it gave errors in the S4/S5's so they trashed it and went to a basic file for everyone.

I haven't been a fan of apr since 03? they put a file out for the vw 1.8t which gave a checksum error code. Their fix was to wipe out a portion of the ecm that stored the vin info. It fixed the checksum code but later down the road when inspections were due,the state pulled the vin from the obd port and guess what? Failed. I had to buy a new ecu. Ever since then, I do not buy apr tunes for any vehicle. I'm sure if you googled it there are posts about it everywhere.

As for using another tuner to modify that, apr prob locks the ecm so it can't be read/modified and bootlegged. Which I would understand the reasoning for that,business is business. I hate to say it but I think you're stuck with it unless you opted to try another tune or keep harassing them until maybe they break down but that's prob a waste of time.

Obviously this varies by year and model, but here's a quote from the DS1 manual: "If you have a TCU tune, you can change the rev limiters in your OTS map to suit. We cannot cover all combinations in the OTS maps and tend to leave stage 1 and 2 stock and raise the limits on 3 or higher to 7000 RPM. If you want to optionally change the LED display on the tacho you can also search for “instrument cluster display”".

Maybe some DS1 users can chime in about whether they've actually changed the LED display this way. If they confirm this is correct, my guess would be the APR system also has the option, their sales people are not aware, and the variation among customers depends on whether the installer has played with the software and found this option.

[Audisthesia]

Yes you can change the LED with DS1.
