I am sorry to hear that you are not happy with the software upgrade. Have you done any other upgrades to the car? Did your dealer program the car with the matching octane that is in your gas tank? I can't think of any reason they the 20+ clients that I have sold the software to are happy with their purchase and you are not.

What do you mean when you feel like the turbo kicks in at 3 or 4 thousand since you have an S6 and it is not turbo charged?

 

Hi Matt,

You are correct, cannot explain why it feels like Turbo.
When it reach 3-4 RPM, car vibrate & shoot out.

I am taken the next step now, calling APR directly.

Will keep posted.

 

language barrier

He's saying that it feels like nothing happens...then a big uneven hit of torque at 3-4k, like a turbo hitting boost.

He's also in Vancouver so I'd submit that he's certainly not suffering from octane defficiency as 91 and 94 are readily available.

 

Just finish talking to Evan, will try the last time, if still not work, then Full Refund.

 

Your 'impressions' do NOT coincide with the actual driving impressions of R8 V10 owners on R8talk.com where there has been nothing but universal praise for the APR tune.

My next suggestion was actually to take yourself to an R8 forum and see what they say the best is. seems they like APRs tune over there. But there may be others. I don't know cause I don't own one lol but one day I plan on it

 

Because the R8 V10 is the detuned version of Lambo 560hp motor it was pretty easy for APR to get that power back and they admit that. Before supercharging I did APR 93 octane tune on my R8 V8, Dyno'ed before and after and found gains to be about half what they claimed. APR gains were 12 hp and 7 tq gain at wheels. Still felt for a little less than a $1k the gains were worth it since it also improved the way the car drove. Biggest problem I have with APR is besides my R8 I also did my previous RS4 and they never came out with full program for either of them and I'm sure same is going to happen with the V10. Seems the duel ECU's is giving them problems

 

Agree with everything you're saying. I would have to get the 91 octane tune for my R8 V10, and whilst I know that the actual hp/torque gains are pretty small, the increased driveability and torque low down makes it worth while. I also have no doubt that APR won't release the 'full' tune for the R8, and that's a real shame.

Put out the extra coin and go with MTM or ABT.

 

My technical support rep is out sick today so my timeline may not be exactly correct, however this is what I was able to fine. I did some research and saw one customer flashing between stock and 91 octane several times. This customer has a naturally aspirated S6, so it's not turbocharged. Our ECU Electrical Engineer tasked with creating the files and hosting them on our server was able to pull up a report of all customers with this specific box code and software revision and noted no other customers have complained. This customer flashed back to stock on the 27th. I believe his dealer alerted us of strange behavior with the customers flash after returning to stock. It's not possible to go into full detail about this strange issue during the flash, but it sounded specific to his particular vehicle and function was changed in case any others exhibited the same behavior in the future.


On 4/7 he flashed the car with 91 Stage I twice in a row.
On 4/16 he went back to stock then back to 91 Stage I again.
On 7/25 he went back to stock.


I'm not sure his dealer was working with us on this issue. It appears they tried flashing it back and forth for diagnosis reasons. Again, my technical support rep is out sick today so I'm unable to ask if he worked on this case. I confirmed the flashing routine was altered on 7/29 so he should be fine if he were to ever get the software again.


I would like mention we do flash several hundred ECU's a day and issues are few and far between. Regardless we keep a log of every single ECU upgrade so we can always look back at the logs if anything strange ever occurs.

 

Yep, pretty much.

 

I'll just throw in that I've got 23k miles on my S6 with a milltek non-resonated exhaust and K&N filters. The APR tune has performed well for me from the first day I had it without issues.

 

There isn't much support for these brands in the US or Canada. Your looking at sending your ECU over seas for ABT and mailing it out to the states at the very least for MTM and they aren't any better than APR. In fact they don't have even 1/4th the global brand recognition that APR has.

 

people who bought the APR tune for the 4.2 S4 and RS4 said the same thing too...'universal praise'. So did people who paid $10,000+ for a PES supercharger on their S4/RS4/R8...'Wow! It really transforms the car! My dyno sheet proves this!'

That is until they performance tested their cars. I'm talking about measuring acceleration.

The guys you want to talk to are the guys who

a) have had it for a few months
b) have other options for making power

Since there are very few R8 5.2 cars running around...even fewer are APR tuned...it's tough to get any long term impressions. Since there are virtually no performance parts that work well on the R8 5.2 other than high dollar forced induction kits, people are 'satisfied' by jumping over a much lower hurdle than they would be if there was a robust market full of great parts.

This happened on every normally aspirated Audi performance car over the past 10 years. It's a broken record.
