Hopefully with the planned RS3 RR day we have planned we'll get lots of data that will assist us all in the future with regards APR software and any updates  :up_it:

Had it with mine. The car had exactly 400 with bad gasoline (95 octane) on the dyno. Then added better fuel and suddenly the car makes 438 on Dyno! Massive difference...

My car only runs on v+ power which I believe is 98-99 Ron

Hi mrAudi,

 

The problem is.. that not every gasoline station update their fuel. The first time on the Dyno the car made 438. Some months later the car only made the 400 with the same gasoline. The problem is that the gasoline is too old or just bad quality batch.

It's not just my car with problem it seems to be most RS3's running the same software so the software must have a big part to play

Its not just about it being old or bad batch, it is where it has been stored, in what temperatures it has been stored, how old the shipping lines are that it has been transferred in to the storage facility, how old the storage facility tanks are + there are other factors that can add to this

My friend used to race in the 250 british motorbike champoinships and he used to filter the fuel twice before putting it in his bike and you should of seen the crap that was in the filters that was not visible to the eye and you would not expect this with todays technology and for how much they charge you for it....

Hey guys. Just wanted to give everyone a quick heads up on what we are doing.

I have arranged for a customer to bring their car for a full dyno logging session and liaise with APR in the US to see if there are anything untoward within the logs.

As part of the diagnostics I have another car coming with a similar setup to do the same logging and create a comparison table for the results.

Hopefully we will be able to remove some of the possible uncertainties such as dyno accuracy and atmospheric conditions, fuel quality.

It might take a while to get to the bottom of the issue (if there is an issue) but please know we are actively looking to keep everyone happy and fix anything we come across :)

Hey guys.

Today we had two customers in with TTRS of the same spec, but with differing software (APR vs MRC)

A picture speaks a thousand words:

 

APRSTG2VS.png

The important aspects of the above graph are:

 

  • Difference in peak HP is only 2hp.
  • Difference in peak Torque is 45.32 up in APR's favour.
  • The delta of the graph shows, at 3.5k RPM a considerably higher torque and HP figure.

     

Both the above cars have uprated intercoolers, and one thing we do know is that the 2.5T is highly susceptible to heat soak.

Hopefully this answers a few questions; im sure there will be more questions to come and the RR day we will see a lot of data :)

The figures are all over the place as MRC have just posted on FB a Stage 2 TTRS with 431ps and 677NM (499 Ft. Lbs.) which is more than APR. So not as black and white as hoped.

Im now ready to get my car mapped next week ,,,with all this going on its very confusing on which remap is the best one to go for.

 

I was just about to get a APR one and now this has made me think again until all this is clear with all these figures being thrown about 

 

Any thoughts  please ?

Where do you live Roy? Locality of the remapping agent was important to me and would suggest the same to you.

I live in Kent , about 10 mins from Dartford tunnel....

AMD Lakeside is my closest APR dealer but heard funny reports from these from others since enquiring , and Tuningwerx Croydon the next......... still unsure of what remap to have now , might hangfire until all this is sorted ............. not sure im making a mountain out of a molehill but this topic has made me unsure now as its been rolling for a long time.

What you've done is run an APR car against an MRC car so its still not answered the important original question why are some cars with the APR map not reaching the advertised figures ,which is nothing to do with putting an APR car against a MRC car.

More importantly it could be said they've been ran on an APR biased Dyno ????

There are a couple of Stage 2 APR cars on here with the same mods and both ran on Independant dyno's with no ties to the software provider at different ends of the country however both came away with near identical results, less than 400 bhp peak.

I am one of those people, I also at my own expense ran my car on the same day same dyno both stages of the APR map back to back and although stage 2 has much more torque it has less bhp ??

Not sure what else can be concluded from that, it's the fairest possible test of the software is it not ??

What have you heard thats "funny" about AmD out of curiousity Roy?

Think I'm gonna go for APR in the not so distant future, but still not a 100% as I've been hearing a lot of good things about MRC recently.
