Tuning Question

[adamleaf8601]

I want to know the community's opinion on eurodyne tuning. They are a company out of Ottawa, ON; see http://www.eurodyne.ca.

I am looking into tuning my A4 but cannot decide between APR, Eunitronic or Eurodyne. Eurodyne appears to offer the most increase in power, 267/330 respectively.

Has anyone purchased this tune? Is it good. What else would you reccomend in this price range, $500-600?

[Nano909]

I went with APR because their tunes are known to be conservative for longevity and reliability, also for their huge increase of power. I daily this car so that was a huge factor.

[adamleaf8601]

Do you find that it gets rid of the turbo lag? As well, how much torque and horsepower did you gain from the tune?

Almost all of the stage 1 tunes are comparable, roughly +60 hp +60 torque. APR's claims are actually slightly higher (284/338 crank on 93 octane) than the Eurodyne numbers you posted. And yes the boost kicks in much earlier, near 2,000 RPM. I also went with APR due to their large install base and the correlated reliability, as well as the easy access to authorized tuners.

Does APR void your factory warranty? Is there any way to temporarily take off (and not leave a trace) the tune when bringing your car to Audi for warranty related work and diagnosis? My worry is if I get the tune and then the injectors fail, for example, then I wouldn't be covered because they detect the tune.

Yes.

No.

Valid and likely. But worth it.

I just got the APR tune stage1 for my 09 avant and yes it has great take off but I have an issue. It was great but first gear over 4k it would hesitate hard and then take off again hard till shift to next gear then no issues after that through the next gears. So I called APtuning, where I got the tune and they thought it to be the diverter. So I got one. Put on and seemed to fix it but started to idle rough. Have four faults... I had the two actuators before when I changed out the coil packs had to replace those two connectors and had those two come up till I was able to get a good connection. Drove fine for several months till tune. I tried fiddling with them but they keep coming back and the other two have not. I had some misfire on those two cylinders one time as well. I tried to get these to go away a few times and now car will not start at all just turns over. I have not had any issues with car before the tune. Any ideas. Called the place as well they are not sure why thinking it is a coincidence. ??

If the car won't start i'd first look at ignition related items. Check your spark plugs. Do a load test on the battery. Perhaps your starter needs to be replaced. There also seems to be some timing related faults, that could mean that the chain has skipped a few teeth or something related to the tensioner breaking (common on B8s).

[05s-4Cab]

Ok I was afraid of the timing chain issue but I have new coil packs and plugs since November. I just know that the actuators were an issue when I did that work because they were broke and had to replace them. That was not easy to get resolved a lot of playing around to get good connection. I did not want to tear the front end apart though(((

[DetRebel]

Look at the integrated engineering tune.

You can add their tune yourself, idk if anyone’s checked to see if their undetected by the dealership when re-flashed to stock.

I second IE tune's - have gone stage 2 from stock, and it is excellent

I don't know how APR or any tuning company can market themselves this way. From experience in the B7 forums where a good number have apr's software on their ECUs, they're no more or less problematic than any other.

I just checked out the IE website and the power gains are confusing. They claim 68bhp gain but the chart right above that shows gains of 45bhp.

The ECU has a flash counter. Feel free to try it, but 99.99% chance it will be detectable. Best to go into any tune with the expectation that it'll void your warranty.

Thanks for clearing that up. I’m in the high mileage club so that’s not an issue for me.

I’m approaching 115k in with in a month or so. I have to do all the major maintenance repairs before I start looking at tunes.

Definitely a good plan. Tune won't directly break anything, probably, but it's an added strain that I wouldn't recommend doing before the catch-up work is done. Get on that timing tensioner ASAP; I know of a few that have failed right around your mileage.

eurodyne has pretty much all but abandoned this market, and their tunes suck as does their software on this platform. APR is better by a long shot, and there are alot more up and coming brands like IE that are offering much better support.

[bhvrdr]

If youre in canada you may want to hit uo Unitronic for their local presence and flash at home capability.

I had an apr stage 1 b8 a4 that had a catastrophic piston ring failure while the car was still under warranty, I got the car flashed back to stock and took it into the dealership and they didn't detect that the tune had been there and got it repaired under warranty. They also had a rep from Audi corporate come to inspect the car, so I would assume if it didn't get caught under those circumstances you could get away with it in any other situation. The shop that flashed it said they hadn't ever had a warranty voided because of it, only when people go into the dealership with the software on the car at the moment.

I contacted IE and they said their tune does NOT deactivate the flash counter so it will be detectable from the dealer and you will get TD1 flagged..

The Flash counter is not involved in the auto scan that triggers TD1.

Not what I have heard or even been told by tuners... EPL to name one who resets the flash counter... And IE who said that even if you flash back to stock it can still be seen in a scan...

Would you care to elaborate since you seem to know so much about it from all your posts on the subject?

epl doesnt reset the flash counter and have written multiple times its not involved in a spec/actual.

That is what I was told by Chris and what is said in the Q5 section... I guess we all misunderstood that or he was talking about something else...

Thanks

[Chris@EPL]

We have said many times that we do not touch the flash counter and with the Simos 8.4/8.5/16 ECU the flash counter is not part of Audi's testing protocol. No idea with the A4s and they have a totally different ECU.

TD1 is not tied to flash counter. Audi did change their TD1 system.... its VERY easy to un-TD1 a car now a days, far easier then before and has ZERO to do with the flash counter.

I will not post about this anymore publicly, but if any EPL customer inadvertently get TD1'ed (forgot to flash to stock or maybe needed an emergency tow in) - email us privately.

This is not correct. Currently flash counter is not tied to TD1.... this has been well proven at this point by our customer base.

So does your "stock" flash reset flash counter and checksum? Is it detectable at the dealer like the APR one is (even though they said it wasn't)?

Currently the flash counter is NOT tied to TD1 and yes the checksum will match.... its an actual OEM file.

Heres a noob question for you guys: Could you keep your original stock ECU, purchase another ECU have it tuned and swap them in and out to avoid detection from Audi?

Not anymore. The ECU has immobilizer functions tying it to the VIN on the car. If you swap in a new ECU the car will not start. In order to clone the ECU to the VIN you need an SKC (secret key code) generated at the dealership. So you'd need a dealership to program each ECU each time you swap. The other way is for a high level tuner to remove immobilizer functions. This has been done but good luck getting it done without knowing someone.

Another vote for IE's tune. I went from stock to stage 2 (93 oct) and have been loving it. Very smooth power increase throughout low to high RPM range. If you catch one of their sales, you can get the stage 2 tune plus DIY cable for less than $600.

I went with APR because their tunes are known to be conservative for longevity and reliability, also for their huge increase of power. I daily this car so that was a huge factor.

Don't quite understand the logic here, though I see a LOT of posts saying the same thing. If you want to be conservative for longevity and reliability, wouldn't you just leave your car stock?

To me, a conservative tune is like eating fat free ice cream--it will still get you fat, but will taste subpar. May as well get the regular ice cream and enjoy it or skip ice cream altogether.

isn't APR more aggressive than IE??? From my research APR has the highest gains over stock (whether that translates to a noticeable difference is up for debate)

I'm leaning towards IE stg 2 myself....

Just about every stage 1 tune is similar in output.
