APR has the option of putting the ECU in stock mode. While its "stock mode" program is not exactly the same bits as the Audi OEM tune, to my knowledge no one can tellany difference, bothperformance wise and measured.

If you can see yourself going past Stage 1 (usually used to refer to a setup where the only engine mod is the reflash or "chip"), APR has other parts, i.e., downpipe, cat-back exhaust, and intercooler, which some believe are "tuned" to its software, for a more complete, tested package.

 

Ok...Im 80% convinced that chipping is in the cards (20% terrified of my engine swallowing the impeller). Who on the forum has the most miles on the stock turbo after reflash?

 

I knew people that 100's of thousands of miles on other similar turbos. There wasa poll on another forum that discussed when the turbos failed, and the tunes associated. If I remember correctly, there is only a slightly reduced life of the turbo when chipped, as long as it is maintained properly. I'm sure that our turbos are somewhat similar.

Cheers!

 

so when you switched it back to stock mode, is it even the ppl who service the car won't notice it. I am afraid to chip my car because of the warranty.

 

the problem with some of the "switchable" chips is that to accomplish this the entire code is re-written

whilst i agree that these companies have done an amazing job at accomplishing this, there have been instances where the ECU doesnt respond properly to login commands or any other commands
any tuner who writes his own files will tell you to avoid the switchable stuff all together, even if you dont buy there stuff

not sure about the neuspeed, but if its just a straught chip and isnt switchable then its the safest for cars under warranty
if the warranty isnt an issue then turbo life and wear arent an issue eaither

whichever way you go these cars make phenominal power and once you stop burrying the throttle youll notice an improvement in fuel consumption

enjoy

 

ChiplogicUSA > I believe you are correct about the switchable ECU's. Neuspeed's is not switchable and as you stated, can be re-flashed to the EXACT original settings - making it completely undetectable by the dealer. I have confirmed that Neuspeed has the original settings on file FOR MY CAR specifically. A have also heard that the ECU's that are switchable do have to re-write a section in the system that makes it impossible for them to be flashed back to stock.

As a side note, my rep at the dealership is aware that I have a Neuspeed chip, and doesn't care a bit. He lets me know when they are going to have to wipe it out due to a factory update. It does not affect the validity of my warranty at all.

 

If you are going to chip your car, put in a polyurethane dogbone bushing. It will reduce the wind-up in the whole engine/transaxle cradle dramatically, and with it the wheel hop / flashing Stability lights and general misbehavior coming off the line. So will an LSD (Peloquin or Quaife), but the bushing costs $40 and you can do it yourself.The LSD costs $1500 and at least a another $1100 for the install.

Installing the bushing made me rethink the necessity of the LSD, which I was ready to do.

 

First I have heard of this. Where can I get this ? Do you have a link?

 

I think all "chips" can be written over. When I had my I3 ECU update at the dealer, the process overwrote my APR Stage 1 program. Whether it is switchable or not has nothing to do with the ability to overwrite the "chip" to restore to 100% OEM tune.

Re: bushing, another alternative (~ $200), you can get the VF-Engineering dog-bone mount, which replaces the complete mount instead of just inserting a polyu bushing in the OEM mount.

 

thanks.
