Want control of my own flashing at home, not rely on APR agents. UniTronic lets you flash from home with LT & their cable.
Want to try lower torque and higher power option of UniTronic tune. APR has a higher torque and lower power. I think the S3 could benefit at the top end with more kW.
Have a few small annoyances with the DSG tune.
Concerned with the longevity of pushing +500Nm on the DQ250

Overall APR remains an outstanding tune, I can always go back to it free as stored for my VIN with APR.

I saw this yesterday on FB. Guy flashed TCU at home via Unitronic cable.

Yes, UniTronic has good deals on ECU/TCU combos.

The deltas between APR and UniTronic are IIRC, basically UniTronic has +15kW and -40Nm.

Should have it loaded next week when I get the cable.

Note that the flash counter isn't reset with UniTronic, but upon a lot of research there is no evidence that a TD1 is automatically flagged based on flash counter. I suppose it could if the techs dug in and had a good look, but very unlikely and TD1 and doesn't really concern me. I notice that you can see the flash counter in VCDS (need to look at this further though)

I sent my box codes to UniTronic and both ECU & TCU are supported.

thats great, do they do a RS3 tune? also how long is the flash time and will it raise a TD1 flag?

Doubt they do cars that aren't available in the US. Flash counter not reset. No reports of a TD1 after being released for the S3 12 months ago.

Their sales and tech support seem good. Much smaller operation than APR though.

You able to send me some links the purchase and info? seeing as i have stage 2 i think it would be fantastic to try at least.

You have to buy through an agent such as ModdedEuros. There is an agent in QLD, but his pricing was excessive. There is no customs duty either as all they physically send is the $150 cable, not the software as that is downloaded. Here is UniTronic's web page: https://www.unitronic-chipped.com/ecu-tuning/Audi-S3-20L-TSI-Gen3-2015-2015-stage1plus

The cable VIN-locks, so 1 cable per car and cannot be unlocked. VIN is supplied at time of purchase. All up cost me $1800 for a stage +1 and the DSG. You'll probably go a stage 2 though.

Possibly the stage 2, all i need is the air intake, i have the sports cat, intercooler. Although just going stage 1+ would be good and the sports exhaust and intercooler would provide a bit more on top of it close to what their stage 2 is

They offer upgrade pricing across stages. +1 to a 2 is only $100 USD. Just buy both and switch between them at home. TBH intakes are mostly snake oil ;)

Yes, but no DSG tune from EuroDyne. Also didn't support my ECU box code. Again too much torque, I want the kW.

Speaking of @home tunes, I have flashed a number of B6/7 S4's with JHM's ECU tune from home with their cable. The software looked like a re-skinned version of APR's dealer flash software. The process wasn't user friendly but if you're savvy it wasn't a problem. Would be great if APR could offer it some day. Of course of the four S4's I flashed all four had different box codes so JHM had to cut new files each time.

Not exactly on topic but thought it would be interesting considering the @home vs dealer discussion.

Really interested to hear your views comparing the two once you've had it loaded for a while and some time to drive it round. I'm currently APR stage 1 also.

I have used DIY flashing for many years on my other vehicles and the interfaces were simple to use. The Unitronic interface looks very straight forward.


Really interested to hear your views comparing the two once you've had it loaded for a while and some time to drive it round. I'm currently APR stage 1 also. Yes will do, Not expecting much difference as the APR is a great ECU tune. The Unitronics will have less punch around town, but more power around the top-end. Should be smoother too as more linear delivery.

My primary reason is to be able to do flashing myself. Secondly, less stress on transmission.

The APR DSG tune somehow seems to be moving back to stock behaviour in certain gears... for example under light throttle in D it will go from 4th gear @58kph to 5th->6th by 62kph which is well below 2000rpm. A few months ago it didn't do this. I could take it back to get re-flashed by APR, but can't do that every 3 months. At least with Untronics I can do it myself if that re-adaption of the DSG occurs, although from my research, their DSG tune could be a better fit for me as targets RPM post up shifts to be >2200rpm.

We'll see. I have a 15 day trial with Unitronics and may revert to APR.

- As I don't have VCDS, does anyone know another way to get the ECU & TCU box codes that Unitronic require?
- Unitronic mention brake / throttle decoupling (my bent :beat:), but is it part of their ECU flash (like APR) or TCU flash for DSG?

Contact UniTronic. They reply fairly quickly.

I believe that the box codes are labelled on the actual ECU/TCU.

If (like me) you don't have VCDS, or don't want to get your hands dirty finding the actual ECU/TCU labels, there's another way to get the ECU/TCU box codes.

I asked my Audi dealer for a detailed diagnostic printout. I got 54 pages of A4 printout - "Offboard Diagnostic Information System - Diagnostic protocol(Long) - Protocol type: Guided fault finding - Protocol status: Final protocol".

UniTronic apparently found my box codes somewhere in the first 16 pages, but I have not deciphered them yet:confused:. Any clues on where / what to look for - a 'software' number?

In the other tuner threads (ABT, APR, JB, Revo, etc) there's concerns about AFR / Lambda data from dyno runs, and timing pull.
What's the story with UniTronic?
Being a flash tune like APR, not an add-on box like ABT, are there issues? What about boost (psi) for that matter - any info?

PS. Should there be a new UniTronics thread for these posts?

I have VCDS, so never been much concern to find them.

I believe the box codes is the 'label no'. Mine are 06K-907-425-V1.clb for the ECU and 0D9-927-770.clb for TCU

A flash isn't going to have AFR issues as they can control fueling and timing. APR will produce more boost than UniTronic.

Label files are core definition files used by Ross Tech to define how to interact with each module

Locating box codes (https://www.goapr.com/support/boxcode.php) are straight part numbers and software revisions

Two things I've noticed after getting the APR tune. Oil temp rarely goes above 100, maybe 102 is the maximum I've seen on a hot day - bonus right there.

The other is L/100km, which still doesn't go beyond 40.3L/100 when I release all the ponies (same as pre tune). Could this be a limitation of the fueling system? My Mk6 GTI with stage 2+ would often report over 60L/100km with the factory fuel pump.

Yes, JHM software is a re-skinned version of the APR Browser that APR dealers use to flash cars.
