JB1 Conundrum...

[jpy1980]

Have a conundrum that maybe you guys can help me out with.

I love my JB1 Audi S3 (Especially with my e20 blend), but recent trips to the dealer for regular maintenance had me uninstalling the JB1 and reinstalling when I was over with it.

This uninstalling and installing, switching maps when I go to the track (I daily drive with map 1, but at the track I was advised to use map 6) and also having to mix e85 to get a e20 blend has gotten to be quite tedious. Yes I know, first world problems. BTW, I can't live without the power from the e20 blend. Its so addictive!

At this time I am thinking maybe I should sell my JB1 unit and purchase an at home tuning solution like Eurodyne or Unitronics. I'm thinking a refresh is all I need when I go to the dealer and I don't have to get my hands dirty. Also, I am under the assumption that I can just set it and forget it, especially if I go to the track. Also, from what I read, the power from the stage 1.5 tune of Eurodyne is similar to my jb1 with Map1 at 5.0 with my e20 blend (e85 and 91octane). Am I completely wrong here? Has anyone made this switch or would anyone else not advise this move? Any advice would help my decision!

Thanks!!

Is you map6 significantly different from map 1? I changed mine mainly to increase boost on 100octane, but for the most part its a quick change.

As for the dealership visits, I went twice without them saying anything, the third time they did. Its always a gamble.

If you are not concerned with warranty and are really changing maps that frequently, a flash tune is prob better for you.

FMI, doesn't e85 mixes ruin/corrode your fuel pump with prolonged use?

If you can wait, the jb4 is suppose to be dropping sometime near the end of year and will allow you to do map changes via steering wheel (or some other way and on the fly).

Personally I never went with the flash tune mainly cuz of warranty. When that is up, flash and turbo upgrade will most likely happen.

I was similar to you....I had a JB1 and had 1st dealer visit so I took it out and sold it. I ended up with a stage 2 ecu/dsg and after a few days asked for a refund. I regretted selling the jb1. I am patiently waiting for jb4 now.....

What was wrong?

[jiannu]

What was wrong?

Well I could not justify spending $1400 for the ecu/dsg tunes when the jb1 did pretty much the same thing.... Yes the tune made the power much more linear and smoother but come on......

[AnthonyA3]

A tune isn't worth the risk of losing your warranty. I'm also on the fence about getting the jb1 or waiting for the jb4.

[geralis32]

why not get a giac tune with a hand controller, you can flash it back to stock, stage 1/2 or e85 mix

I'm confused, OP doesn't want the jb1 because he has to take it out for service which means he's worried about his warranty. I'm pretty sure a giac tune is just like every other tune and it can be detected if the dealer wants to find it.

Most of the flashes are now hard to detect when reflashing back to stock. Eurodyne for sure has been proven not to be detected. APR if reflashed properly has not been detected for most people. I think he is just tired of the physical work, plus trouble finding the proper fuel mixture to equal what a tune can give without having to do anything. I think he actually is willing to take the risk of losing warranty, when all he has to do is reflash the ecu for service.

This was my understanding as well, at least for Eurodyne (which I plan to get). I'm sure the risk is still there, but minimal. There may also still be risk with piggybacks given the recent tech bulletin that the ECU updates can detect them (possibly permanently logging overboost codes somewhere). This wasn't confirmed, but I imagine Audi would like to prevent piggybacks from sneaking through.

[AnthonyA3]

Well then if that's the case with the ecu logging over boost I might just look into the eurodyne tune.

[coolwater]

Eurodyne is the way to go. I've gone in 3 times after flashing to stock and no td1. Once it was for misfires and they were digging deep to try and find out what happened...

Flashing from home is definitely the best option.

You could by the Jb4 connect kit and then you can change maps with mobile/tablet over bluetooth.

Btw, just read through the long Eurodyne thread at Vortex Golf R section and there are indeed some
references to blown turbos and cars that have gotten TD1 flagged after 'stock' reflash.

Just saying without intention of a flame war...
Actually got curious and started reading the thread after several positive Eurodyne comments here.

That's interesting, I know of 1 s3 that blew a turbo at the dragstrip and was towed home. Flashed back to stock then towed to dealer. Everything was covered under warranty.

That doesn't mean AOA can't change how they detect a tune, but so far so good for me. I do make sure to drive at least 20 miles on the stock tune before going in.

How would the ECU log over boost if the sensors that the JB1 manipulates are telling the ECU its not over boosting? That's the point of the JB1.... the car thinks its at normal boost when its not. You would have to compare STOCK Air flow numbers of a non JB1 car to the JB1 car to tell if there was more boost.. that would be a MAJOR time consuming pain the BUTT which NO dealer would go through to prove. The JB1 is only having the car add more boost since the car thinks its at say 7 psi instead of 10 psi then adds whichever amount of extra fuel needed by the extra boost by crunching the Air/Fuel numbers set by factory programming.

I'm not an advocate for JB1 over tuning, but JB1 would be harder to detect over a flash. I'll be flashing once I get my intercooler and DP, but I know the risk involved.

Yes, the statistical risk of both getting a serious issue with engine / turbo / drivetrain and then also getting TD1 after flash back to stock is ofcourse very low.

The S3 has the same engine and gearbox as Golf R and Leon Cupra, and nearly the same as all other Mqb 2.0t models though,
so you have to take those cases into account as well.

There are no known cases so far of cars having gotten flagged with tuning box,
after removing box before dealer visit.

Ofcourse one cannot rule out that methods improve and that it happens in the future.

There are however a bunch of known cases where flash tuned cars have gotten flagged,
even though having flashed back to 'stock' before dealer visit.

I.e. with respect to S3/A3 8V, Golf 7 and other Mqb platform models...

[rhexis]

first post for me. leased an s3 about a month ago and after 600 miles flashed with eurodyne stage 1.5 93 and then a week after that did the dsg flash. the only other mod was replacing the stock air filter with the k&n filter. i have 1050 miles on it now and the car runs great. warranty be damned!

I think the cars that have been TD1 from reflashing the ecu had to do with flashing the stock "tune" instead of flashing the OEM stock file. There are risks in using both piggybacks and flash tunes.

[saxon]

Reflashed to stock with #unitronic and no td1 after a service where it was plugged in

[jpy1980]

So are you guys saying that if I ECU tune my vehicle then I can never get my oem stock tune back on? It will always be a stock like tune? When I tuned my WRX with this tuner called the acessport, it would actually save my oem stock tune. That was awesome when I had to revert back to stock.

What does this mean? Did you keep the piggyback installed each time, and they noticed it on the 3rd time? Or, did you have it uninstalled each time and they somehow detected it on the 3rd time? JB1 is diagnostically invisible. Unless you were messing with boost levels and maps.

Yes left it in the car mainly because the service was nothing that would warrant them looking for anything besides an oil change and fluid top off. The last visit was because they screwed up the car and couldn't figure it out and thus scanned the car and found everything. Will just keep it in from now on since notes specify I have the device. So basically warranty will be hard to get if I do have problems down the road... Granted the car does prematurely already burn oil too quickly.

Something like that.
Some information will still differ compared to before doing the tune flash.
(Don't know what exactly, have read different explanations. Only VAG knows for sure.)

If VW/Audi central office does a thorough scan that will be detected, and the car will get flagged.
To my understanding this practically only occurs at warranty claims for engine/drivetrain and not every time.

The simpler auto scan at services does not seem to detect it.
Have at least not read about any such case.

What everyone is trying to say is when flashing a tune you upset or there is a counter something like when you ticker with cellphones there is a flash counter and on a virgin phone or ecu the value is always 0 but when you flash even when you resort back to stock its value changes to 1 or another number other than 0...Guys that reflash back to stock and visit the dealer with out TD1 are lucky....

Eurodyne resets the flash counter to 1. Could be problematic if you have updated software at dealer a couple times. But at least they attempt to set the flash counter back.

Old thread I know but what kind of fuel economy have you all seen fro the JB1? Also how crucial is it to run 91 on the 91 setting, will it hurt if you ran 89 Octane?

[jpy1980]

Even without any tuning, I'd always run 91. Why put anything less unless for some reason, it's an emergency and that's all they have. Even then I'd put a couple of gallons to get me to a proper 91 Octane pump.

Fuel economy really wasn't a concern because any savings was negated by my right foot.

Really though, don't put anything less than 91.
