Hi folks,
My first post. I have a new to me 2004 RS6. In order not to void warranty, my dealer offers the GIAC ECU/TCU chips. Does anyone have any negative comments about this product? All responses welcome.
Thank you in advance.

This is a loaded question. The best way I can say this without opening a can of worms is to recommend steering clear of GIAC, and leave it at that. If you're worried about warranty issues, find a tune that offers a flash loader to allow you to flash back to the stock map when you go in for warranty service. Search Viper and Eurocharged, there's plenty of info here. Welcome aboard by the way.

EPL tune, I wont say more then that because i have no experience with the others but can vouch for the EPL one and the services that goes with it. You will find that everyone has there own opinions so be prepared for everyone to respond in different ways.

Now you say 2004??? where are you from?

Oh and the Giac tune is being done by the dealer for you?? Oh you must be from Toronto and have gone to Pfaff tuning LOL you may want to PM me so we can talk and FAST!

Sorry, my response has much more than opinion to back it up. I can drag out the data logs all over again if needed. In addition, I dont really wish to drag out the GIAC data logs and play the dead horse beating again. The guys have all seen the footage.

Please post up your EPL tune data logs for others to inspect. Should be fun to see some concrete data.

As for the TCU, it is a no brainer. Go with MTM from Hoppen. Price is reason enough, but the Giac TCU chip is barely better than stock.

Here you go, but i am sure most have seen this already,

Blue is Stock, Green is with the tune, Red is with Custom Turbos.

DHall: The GIAC logs aren't only from my car only, correct?

If so: A = Bad Torque converter, B = Tune was probably the first revision that GIAC ever sold.

Next logs will probably be done in the spring with new/latest GIAC revision as well as a 6 speed, so no longer an apples to apples comparison.

Correct. Your logs were not complete nor had enough data.

Latest GIAC revisions are nothing to write home about. imho

Crayon drawings from retailers mean very little. We need to see the car and verify data logs. 30-60 and 30-90 would be nice too.

So dyno sheets mean nothing... and my Vbox is "not the approved RS6 tool to measure" looks like your S.O.L but if for some reason someone has a "better idea" i'm all ears, Unfortunetly its snowing here today so i'm not going to go out and try to run any numbers and with the salt all over the place it looks like its going to be aWhile till you see numbers from my car.

I have no idea where you pulled that dyno sheet from.

Dyno sheets from retailers dont hold much water for me.

I dont think anyone here is challenging your pbox. But, if you have some data to add via Vagcom, what tune you have and the gains....that would be helpful. The last time I checked your car was stock.

I'm done with this thread. You all can have the epenis sandbox.

Hmm testy...(no pun intended)...

While I agree that dyno sheets are not a reason to buy something, I think the graphs show the potential and the delta between the before and after, forgetting about the hp/tq numbers. Coincidently, my stock curve looks very much like the stock one in the post above.

DHall1 needs all the data in one format to effectively compare tunes. If one of use uses Dynolicious, another Mustang another... we cannot compare HP and torque without knowing the differences between the measuring devices. The same with VAGCOM, VBox verus other data loggers. Let's all get on the same tuning, dyno, datalogging page!

We've been on the same data logging page for two years, Dave and I were doing pretty well compiling logs from various cars. It wasn't until recently that things started getting mucked up with all of these different options.

Sorry but thats the tool i use, have been for Years. and if i knew it would create such drama then i would not post anything, I guess i will have to wait to get a Good day to use my Vagcom, which i have no idea on how to use it yet..

Don't take this the wrong way, I have no problem with the pbox, or any other data acquisition device for that matter. We're talking about two different things here, and they don't mix. We've been comparing tunes using data from the Vag-com to highlight boost, timing, and most importantly, fueling as a basis of measurement. This is how we make determinations of which tunes are safe, and make good power. As you said earlier, if you just want numbers, it doesn't matter how you're logging the car as long as you are comparing to baseline numbers. The only issue that I've ever had with any of your posts is that there is no reason to be posting numbers without a comparison factor. It's pointless to say "I went 0-60 in 4.4 stock" until you are ready to accompany this information with tuned numbers as well. It's never been my intention to offend you, I'm just used to a different routine of gathering data.

To simplify the above, I'm not concerned with performance numbers as much as I just like to log different aspects of the ecu to ensure that the car is healthy.

SteveKen

I've got no beef with any tune over another. GIAC is what I inherited, therefore, that's what I'm using.

No offense, you've all done a lot of work, but I'm of the scientific mind where unless the comparisons were done on the same car, same conditions, etc. then the comparative results are about as useful as the mfg's crayon drawings.

My $0.02, but it's hard to refute.

If I were a buyer, I'd go with whatever is the cheapest.

The purpose of posting a dyno graph is to observe the power curve, and for multiple dyno's on the same sheet, power under the curve. The number is irrelevant, unless that's why you dyno'd. It seems everyone on this forum has a boner for Vagcom, which is great, but it's not a performance software, period. I didn't come here to try to change the world, just open up the possiblity that there are other tools out there to measure performance. I can cetainly use the Vagcom to record my RS6's performance, but why, I use my Pbox for all my other cars, why change. I didn't and don't post my times or my dyno info for all to compare THEIR numbers to, I posted to share MY changes, when I make them. Sorry for any confusion.

The answer to this question cannot be gleaned from a dyno graph. Too rich or lean, or timing issues that impact detonation and can kill an engine are the negatives the author is asking about. A poorly tuned engine can still make horsepower, but might ruin the longevity of the engine. VAGCOM data can answer questions about the tune not seen by dynos and other performace tools.

The author and many of us know there are gains to be had by ECU tunes. Its how the tuner gets these gains that interests many of us.

Sorry for the shitsorm I might have exacerbated, etc.

I guess what I was trying to say is that all of the efforts when not done in a controlled and scientific test only prove that one car/driver is better than another as opposed to which tune is better than another.


Also, to the OP, if GIAC is the mfg that guarantees that you won't void any warranty you have, it's been on the car I recently bought for at least 5+ years without any issues that I could discover. I'd say go for it.

If you get the flashloader and pay some more money, you can easily switch tunes to stock, race gas, performance and valet modes quite easily.

I am spoiled and have a local tuner, that's been tuning Audi's for years. I have no need to log my tune to "check" my tuner. If I bought a tune over the internet, I would be logging every time I drive it...If my tuner says it's OK to post my logs, I will do so.

If a thread is started by another forum member and I post a reply such as the one below. Is that considered "advertising" for Eurocharged? Have I singled out Eurocharged and said go buy that product because its better than all the rest?

It seems that some members think so as complaints have surfaced. Jealous competitors? Who are these people? How far do we need to carry PC on this board?

Forgive me if I have given my opinion. Ha

Its funny because I actually spoke highly of the complainer and his product. Yet he continues to complain. Well, the can of worms is about be opened up all over the place.
