Software Tuning Options

[Devinm5]

I'm looking to go a little "crazy" and get a stage 1 tune on my B6...

anyway, aside from any "Recommended" upgrades (diverter valve, Exhaust, Injectors...you get it) I would like to start a thread with some pros and cons of common tunes.

The ones I'm initially familiar with (and that seem to be the most popular throughout the forums are

---- APR Tuning - Stage 1 ECU upgrade

----Motoza - Stage 1


Just a quick list comparing the two from what i already know


APR Tuning - Stage 1

--93 Octane - 215HP / 245Tq stock
--Free Upgrades to more "aggressive" tunes
--seems to be a more conservative tune
--Includes program switching built into the car from CC stalk.


Motoza - Stage 1

--93 Octane - 215HP / 250Tq stock
--Do not need a dealer to install ECU flash
--Comes with program logging software
--Program switching is external via computer or smartphone (if BT device is purchased)



Who has some first hand experience with one or the other or both, or maybe something different from either of the above?

what did/do you love about it? what could have been improved?

Any stage 1/2 tune will perform the same as they all share the same limiting factor - the stock turbo.

The main advantage of Motoza is the upgrade path and being able to use 550cc injectors and/or E85. With Motoza you arent limited to the hardware supported by the OTS tune (you can pick and choose your own turbo/fueling combo), and with 550cc injectors you likely only have to purchase one set in your quest to mod the car.

I love my APR tune and while people say its is conservative (is it??) the record for the quickest stock turbo is on an APR 2+ car.

Had APR Stage 1+ (tune w/ TT 386cc injectors) for a long time. Decided to dyno the car and it ran dangerously lean at high rpms/wot. Got rid of it in favor of the Motoza/550cc combo. Night and day difference. Car is way more responsive all around and picked up almost 20whp judging from my air meter G/S numbers. The support from Motoza is great as well.

Do you miss the program switching from the ECS? or did you end up going with the BT option with the Motoza? I cant imagine I would be switching programs very often, but it seems nice to have anyway.

What are your g/s figures before with APR and after with Motoza?

I din't log any with the APR software. Just have actual dyno numbers. I used the Motoza software "dyno" function, which I've heard is pretty accurate, to get my current hp estimate.

Not at all. I had the 104 octane "race" file and used it a few times. The standard 93 octane Motoza feels more aggressive than that from what I can remember. BT as in Bluetooth or Big Turbo? I'm currently on the stock K03 but will be installing my eliminator in the near future and then paying for the upgrade from Motoza. May be a while still because it honestly feels like I've upgraded to a K04, and want to enjoy the car a bit with the new found power :)

Too bad, that would have been a good comparison. G/S to G/S. Timing advance to timing advance. Etc.

I know, wish I would have logged it with my Vag-Com or something. Didn't start worrying about any of that till after I saw what happened on the dyno. Didn't want to take a chance of blowing the motor by putting it thru what we saw on the dyno.

Dyno graph for reference:

oh yeah, Bluetooth...

but speaking of Big Turbo, i'm still on the KO3 also. No real plans to upgrade the turbo until I have another car and can turn that into the "project car" until then, i'll just have to enjoy the simple improvements. Good to hear the tune really makes a difference in the feel. When I first went from my 97 VW Golf (2.0 aba) to the audi I was thrilled...TURBO!!...but then I got used to it and it just isn't aggressive enough anymore, even with everything basic that I have done.

At the risk of sounding green, "G/S"?

A stock A4 vs. chipped is like comparing a an ABA to AAA(VR6). Huge difference. My wife had a 96 GTI 2.0 cam/chip/exhaust, etc. We bought the A4 for her and she said it was slow, that's when I had the car flashed w/ the APR software. Drove it like that for 8 years or so and was perfectly fine daily driving. It was always missing something up top though, now I know after putting it on the dyno. Kind of itching to take it back w/ the Motoza file on there and compare the two graphs. No other changes have been made besides the tune and injectors.

Grams per second. The higher the number, the more air is being pulled into the motor, and more power should be being made if the fuel is being matched correctly and the mixture is optimal for producing power.

I have a APR 1 tune and it has been reliable and a good boost over stock.

If I had to do it all again, I would go Motoza.

Reason being....

I have since sourced TT225 injectors and some other parts and would like to go stage 1+ With APR I am forced to drive to a APR dealer and have them do the work.

IF I had a Motoza tune I could doo all work myself in my garage. That is a HUGE advantage. Even more so if you are like me and hate people you do not know touching your car ;)

But you can do it all over again :) You'll feel like you did. Rewrite over the APR file and enjoy your car all over again.

Sounds like Motoza is the way to go...It is convenient not having to take the car anywhere.

I hear ya.

My plans are..

I have 2X ECUs that I need to get "immo off". I have a local guy here who may be able to help me with that.

I will then keep my stock ECU (APR1) for backup or if I ever sell my car.

I will then Motoza one of the "immo off" ECUs and if I ever get a new B6, I can just swap the ECU over ;)

That's exactly what I did :) Just send a spare ECM to Motoza and have them defeat the IMMO. They may not even charge you for it if you have them load the software on there at the same time. I had an issue with the car not starting when I installed the ECM once I got it back. Ended up being an issue with the file not being completely loaded or something along those lines. I read the ecm and emailed them the log. I received a corrected file and I've been cheesing ever since.

I would 100% jump to the Motoza 1+ software, with the Bosch EV14 550cc injectors, over the APR file(s).

I have personally seen a Unitronic Stage 1+ car with some bolt ons, put down 176AWHP/226AWTQ. (quoted my post from another thread below).

03 A4 5 speed Quattro. Stock injectors, Unitronic Stage 1+ (93 octane file) running 94 octane. silicone TIP, 3" test pipe, 2.5" catback, unknown 2" FMIC. 18psi.

I've ran APR w/ TT225 file for years now. Motoza seems like the best option at this point. I'm personally looking into the Motoza K04 tune, not sure if it's worth throwing more into the b6 though...

A K04 hybrid is a great turbo choice for B6. Cheap, and makes the car feel alot more quick over stock turbo.

Not you is it? Saw this while visiting Portland two weeks ago or so while walking around downtown:



edit: looks like Moro Blue now that I look at it posted, looked black that evening/on my phone :)
