APR ECU Upgrade for the Audi B9 RS5 2.9 TFSI!

[joeyoro]

So the 93 ratings are much higher, I've noticed even the MTM and ABT tunes with big numbers are running 93 AKI. I am stuck with 91 in Arizona so my only option is to go and mix Sunoco fuel with 91. The website says not to mix octanes though. Is this just a CYA thing or is this a having to wait for a stage 2 tune for higher numbers for 91 thing?

Looks like APR plus is available for the RS5 stage 1 ECU upgrade. I am wondering if AUDI denies any other claim if you ECU has been reprogrammed. Say, for instance a power window, MMI, seats? etc.

That's illegal.

2 UPDATE

The APR ECU Upgrade is now available in all markets for the B9 RS4 and RS5.



Furthermore, the APR Plus ECU Upgrade is now available for the B9 RS5. APR Plus provides a factory term limit matching limited powertrain warranty and matches the performance of the APR Stage 1 91 octane ECU Upgrade!



Go APR!

What interests me almost as much as the power/performance improvements is the changes to the throttle response. The APR upgrade claims to decrease the lag time between accelerator actuation and response from the engine (not to be confused with turbo lag). I’ve noticed that even on the stock RS5 there is a slight delay in tip in. The tip in delay on my ‘13 allroad was quite noticeable and even a bit dangerous in normal driving. I’d notice it when trying to merge into traffic or quickly accelerate to pass. The APR software changed all that. The car car not only is far more powerful it now immediately responds to pedal input.

The problem isn’t as dramatic on my RS5 as compared to how bad the allroad was but I still notice it. This makes me seriously consider the upgrade...

[S3DUDE]

I surprised that no one has provided a feedback on their tuned APR RS5 yet. if you drive a tuned APR RS5 spit the beans. how is it? kick in the pants? Rain, how far is the 3.0 TFSI turbo tune?

9 days later, I am asking again. is there any, I repeat, any draggy or timeslips from anyone yet? did the guys at APR not run this tune at the drag strip?

I am considering as well for the throttle response. probably the 91 octane since i only have access to a couple 93 stations.

@Arin - do you take appointments for this ECU upgrade at the APR headquarters? If so, how long would this typically take?

No appointment necessary, but we do like to have a heads up! Should only take an hour.

Sounds good. I'm moving to New Orleans next month and I believe you guys are only a few hours away.

I'm assuming you also do the Plus installation at HQ vs needing to go through a retailer?

[Arin@APR]

We do APR Plus in house too.

So is the APR plus version the 91 octane only?

[Arin@APR]

Yes

[DCB1951]

Yes

If one gets APR Plus and uses 93 AKI (where I live, only 93 is available - no 91), I assume there is no harm; is there any measurable benefit?

[Arin@APR]

You can run higher octane no problem and will probably see a pump in power.

[stooken]

Any word on when the dealer tool will be available?

[Arin@APR]

Couple months

[Rob O]

It's worth noting Plus is valid if used on stock motor or in conjunction with "APR approved" parts. So if you have exhaust, intake, etc that isn't not APR ... Plus isn't an option.

Will be sending mine out for 91 soon (only have 92 in Oregon).

[Arin@APR]

APR Plus is to be used with APR Parts (sans fueling/turbo/downpipe). We don't, and really can't warranty other parts from other manufacturers. However, when it comes to the catback, so long as you don't have something that's worse than stock, we're ok with it.

[Arin@APR]

I had someone ask about 0-60 times. While I think this is a terrible test, I gave it a shot an ran 3.2 on a slightly wet surface, stage 1 93.

[idrinkv8]

Damn. That’s moving.

Curious to see a quarter mile and trap speed with the 93 tune

[Arin@APR]

Me too. We’ll take it to the track eventually.

Finally a reference.

A significant percentage of America lives beyond their means. So no, I suspect there are a shit ton of owners in this group who could not afford to rebuild or buy a new engine if it blows up and Audi voids the warranty. APR and other tuners know this. It’s one thing to cover a monthly payment and something else to come up with $10k plus immediately for a new engine. I’m not sure why any tuner would launch a product these days without addressing the issue up-front.

Its funny 95% of the folks freaking out over the APR tune taking so long to be released; are now losing their minds about it voiding their warranty. Just tune the damn car, if it blows up, build the motor. We are all acting like we cannot afford to build a motor, we drive a 90k + car.

You know who else doesn't want engines to blow.... Tuners like APR. If I install their Stage 1 93 octane (as I did) and my engine blows, I'll be talking about it plenty and that is not the kind of endorsement that reputable tuners who care about business want. So they make tunes that don't wreck your engine. Dealers wont offer the tunes bc they don't want their customers having trouble, getting sued, hassled etc. A few unexplained engine blows and demand would disappear, and not just for that tune, the entire brand would be tarnished. So the smart tuner is conservative and doesn't go farther than it should. All evidence so far is that this is how APR operates.
And this is why you go with an established tuner who has a reputation to protect and long term interests at stake. Some random piggy back from a newco that is looking for headlines about the amazing gains is a risky proposition.

Do you have the APR tune on a b9 RS? If you do do you have any acceleration numbers to share?

Thank you for that reminder! Here are my VCDS aka vagcom logs for APR Stage 1, 93 octane. 2018 RS5. Green coupe bc that is a factor. FYI this car also has AWE intake plus full turbo-back "track" exhaust, with the 200 cell cats, resonated, but no muffler.

I think he wanted 0-60 and such
Arin did a pull 0-60 on a damp road in 3.2 seconds

[DCB1951]

And it was a 3.04s pull with the 1-foot adjustment.

What’s the 1-foot adjustment?

[dimadale]

Right. Given that the car doesn't have a proper launch control (right???) Where do people fine the 0-60 times? "S" mode everything set for Dynamic, or "M"?

[Arin@APR]

When most places report 0-60 times (magazines for example) they use the 1 foot rollout times, which are always less time. It helps simulate the time generated by using timing equipment like those found at a drag strip. Some info: https://en.wikipedia.org/wiki/Rollout_(drag_racing)

ESC off
Go into Sport mode (not manual)
Hold the brake with your left foot
Press the the throttle with your right foot
Let off brake and hold on tight

Whilst holding the brake and throttle at the same time the revs will go up to 3000-3500 once there you can let off the brake and go into warp speed.

the key thing to watch is your boost gauge. The boost will build and then start to fall back down if you do not release the brake at the right time. so follow the steps above and as you press the gas peddle watch the boost. when you are approaching max boost, release the brake pedal.

Truth! When it gets about 20% up mash it!

[S3DUDE]

when is the S5 tune going to be available?

1/4 mile would be nice, but 0-60 and 60-130 are interesting too.

I think I need to come see your car . Maybe it's turn to order those lights...
