APS Remap Review

[W8PMC]

Nice one & as said, any good map just adds enough performance to the car to make the job worthwhile.

You'll never get the same monster gains possible from forced motors, but the changes all the same are good & very obvious on road.

Nice thread. A credit to all contributors, especially the originator

Is it detectable by dealers as it seems a mild remap?

If it was "Flashed in" then more likely to be seen.

How so? APS told me they reset the flash counter after the remap is loaded.

I am also very pleased with APS and concur with John's write up. The way the car accelerates from 90kph to 130kph on the M40 (or mph if on an autobahn) is incredible now.

Dirrect "Imbedding" is the safest way of hiding a remap, this takes up to 3/4 hours on the RS4, flashing is much quicker to spot , regardless for the counter reset, they should have told you this "Before the map was put on"

[Adam]

what do you have to do to spot it exactly?

I assume normal Audi diagnostics at any dealer would not pick anything up?

When a remap is done via the OBD port a "Signature" is left behind, resetting the counter does not take this out from talking to tuners.
All the Cars I have had done, used the Imbedded method and never been seen.
Flashing is both cheap and skilless, anyone can do it with limited knowledge.
That's why all these companies have "Sprung up" from no where.
It is common knowledge that the "Flash" method is "Less Safe".
If you are concerned ask another big tuning house what they think.

I would not say the APS guys are skill-less and have hardly "sprung up" as they are the phoenix from the AmD ashes who have been around quite a while; think it is their proprietary coding

I am interested rather than concerned but will do APS the courtesy of asking them first

Hange on I'm not saying they (APS) are unskilled, I am saying that Method is "Less Skilled" and anyone can flash an ECU, thats why so many have sprung up, maps can and are bought by just about anyone who wants to pay.
Ask ASP (in the nicest posible way ) if there map will be seen.

[Adam]

well you did say "skilless" I agree that anyone with a laptop and a distribtuion agreement can now become a chip/remap company - I just don't put APS in that bucket.

I did ask at the time if the code is detectable and they said "no" - I always assume no here means "very unlikely unless they were looking for it and sent it off to boffins at Audi"

I don't know enough about the art of remppaing to interrogate them further on flashing vs embedding but will give Ed a call and have a chat.

[Adam]

It would not be fair to quote a tuner on here so I won't. Suffice to say I was happy with APS's response and warranty promise.

Any remap will be detectable if the factory really wants to find it, whether flashed or "embedded".

which uk tuners us the imbedded method?
thanks

I am glad you are happy with your map and it's better to ask this question for "peice of mind" more than anything, as I said I had cars remapped and all were the "Embedded" method and none were detected at all. Best regards J

Questions....

1) Did you APS-mapped guys get your top speed limiter removed?

2) Will they increase the rpm red line limit if you so wished?

3) I understand that in 1st, 2nd and 3rd, prior to ~5500rpm, putting your foot flat down on the throttle does still not demand 100% throttle (hence the additional rush in the stock car that seems to happen at that point). Does the map remove this restriction?

Thanks.

The main difference between using the OBD port and flashing direct to the ECU's is that when you flash direct to the ECU's there is no interference from other sources and the code is more 'pure' than via the OBD port.

When you flash via the OBD port its a bit like trying to have a conversation in a nightclub.....some of the conversation is missed,
although thats not to say it will work any less better.

Flashing is the best way to tune IMHO, piggy back chips always run the risk of dry joints after a while.

I would not agree that the flash method is less safe, i'd say the opposite was true.

[Virdee Autos]

Another thing I got told by a reputable tuner is that with "flashing", you cannot determine the exact version of the ECU, for example the ECU may have been uploaded with the latest software, i.e B7 RS4 from Audi.

All they analyse is the ECU type, and then upload a suitable map via the OBD. Whereas custom maping can be suited to the exact version.

[sykotoy]

So what method does rthe new REVO software for the B7RS4 Use
???????
