Unitronic flash at home was brilliant during my warranty period. Now on stage 1+ and TCU stage 2 tune. No complaints...

[Mighted1987]

Im going with unitronic too,curious on review in their stage 2 ecu/tcu
My local apr dealer in canada is charging way too high for apr and add on top our local 15% taxe.

We have apr on one build S6 and The Matte fighter jet build we doing Unitronic it’s been settled and this is going to fair for an awesome showdown on the track once both at stage 2 So I’ll keep everyone posted on this grudge match as cars are both 2018 so should be interesting journey on the builds matching up

Stock down pipes and exhaust.

APR hands down for the power gain. Does Unitronic offer a 100/104 MAP tune?

[Helios Black]

Just picked up APR Stage 1 tune with their fall 10% off sale. Loving it so far. Noticeable difference in power. 0-60 went from 3.8s to 3.3. Haven’t taken it to the track yet. Did a roll race on the highway with a custom tuned E63 AMG and held up with him the whole way.

In for results.
It's been a few years since I've seen a unitronic tuned 4.0tt.
At that time, 034's mustang dyno numbers didn't impress (relative to the APR tuned RS7 that was there at summerfest) but we could rack it up to parts in that vehicle's build not complimenting each other.

People were trying to say that the Unitronic RS7's exhaust wasn't creating enough back pressure. Take it with a grain of salt, I've also been told that back-pressure requirements on modern turbo cars is a myth.

[Helios Black]

That was this morning in 45 F weather on a shitty back road. Still figuring out how to properly launch this thing without a real launch control feature like the dual clutch cars have, but pretty solid still. More than happy with APR so far.

Solid numbers and the launch is best when reaching the peak rpm set . Once you hit it boom it’s over lift off !!!!!!

It depends what platform and what stage. If it's RS7, I would say APR all the way.

For S6/S7 it depends on Fuel and Stage.

93 Ocatne
Unitronic Stage 1+ (93 file) makes a little more power than APR stage 2 on 93.
Unitronic Stage 2 haven't seen any big gains over stage 1 for those that have got it.

100+
I would lean towards APR as they have shown solid results for Stage 2 guys.
Unknown for Unitronic as I haven't seen any numbers for it yet.

Stage 3
Toss up. Flash at home with Unitronic, but they haven't mentioned much about it. APR is definitely rock solid and should get you in the 10s, but has a lot left on the table but who knows when they will update the file.

We need quarter mile times. Dyno, draggy, and word of mouth have far too many variables. If you have time slips, please submit to the quarter mile database here: https://www.audizine.com/forum/showt...-mile-database

I don't mean to bash on Draggy. I love the device and have one but every time i run it on the drag strip, it's not perfectly accurate. Draggy times just can't be compared to anything else but other draggy times because you don't know where they really stand. Sometimes it's faster, sometimes it's slower.

Agree with this

Lol, no draggy. Just same day dyno comparisons and trips to Mexico
I posted my times from last year with worn tires and no TCU tune. Was too busy with work to hit the strip before winter so hoping for an early spring. New MP4S should help a bit.

I don't see how uni stage 1 can be stronger than APR 2. Not enough like for like cars, conditions and times to prove or disprove this. Looks like uni I down on torque too. Doesn't really matter uni or Apr is a safe bet for a quick car

Honestly from what I remember it was only a small difference and that was using regular pump gas.

From what I’ve seen I think the Stage 1 APR tune is a little under powered, probably to encourage people to purchase their downpipes. At the same time they went a little crazy with the Uni stage 1 and I don’t think there will be a big improvement going stage 2.

Like I said before both options are good, it just depends on what kind of setup you plan to run and whether you want to flash at home or not.

I made 594ftlbs vs 407 stock to stage 1. The torque is certainly not lagging. Now I'm making around 660ftlbs. I think their early tube was a bit weaker though so could be that.

So it has been over a year since last post . Any opinions on if apr or uni have improved or one is better then the other now . Looking forward to hearing your thoughts ?

I had EPL stage 1 ECU and TCU tune, went [email protected] at the strip (fastest of 3 runs - 12.30 & 12.43) dragy numbers were consistent as well. I have since went with APR stage 1 ECU tune and kept EPL TCU tune, [email protected]. That is enough for me. Almost a half second and 5 mph faster.

That seems slow for the EPL tune, especially the trap speed. I just ran mine and had 12.04 with trap of 118.5, and with launch control it would be mid 11s. Basically the same or even better than the APR time you had posted.

I highly doubt you are going to knock off a half sec just by using LC.

Were those 91 or 93 octane ECU tunes?

Is the EPL stage 1 ECU default tune setup for 91 octane?

Which fuel were you running 91 or 93 octane?

In some states we only get the lousy 91 octane fuel.

The car shifts completely different when you use launch control. It slams into gear and lunges the car forward each shift versus the pops shift you normally get if you leave without launching. It’s definitely faster and pulls harder when you do the launch. I have a 16 rs7 performance so maybe not the same on all cars. I didn’t look to see what original poster has.

[highPSI-S4]

When I had EPL Stg1 and Roc Euro intake, mid Oct 2016 I ran 12.04@115 on 93oct. I had some talks with Chris, the determination was the car wasn't up to date on Maintenance but I bought CPO so it should've been, but to my surprise Audi sold me a car without performing the Maintenance to keep it up to date. I was able to prove this through obtaining the Purchase Order for the parts needed to perform the maintenance. A month after I had m car in the dealer getting the 35k maintenance (Spark plugs, DSG filter and Fluids) done so I'm thinking I'll need to hit the track again.

Oct 2017 I'm back at the track, same mods. Best was 11.89@116 93Oct mixed with 4 gallons e85, at this moment I'm blaming the tune. Was gonna make the jump to APR at the time but decided to go STG2 with EPL and worked with them al little trying to make the Race file a bit more aggressive, my best Dragy time was 11.48@120 so I figured it was all a tuning issue with the slower stg1 times. A few months pass and a buddy of mine purchased a 2013 S7, he went for a second hand EPL Stg1 and headed to the track. Ran a 11.7@118, that had me in my feels. Some cars EPL run hard and other don't but I have seen the same with APR cars according to the 1/4mi database.


Now I'm APR STG3 and couldn't be happier. Car has TQ for days and pulls hard every gear. I will be attending a local Drag event next month to hopefully get some great times to post.

He trapped 119+ on one of his passes and was 60 footing 2.0+. There's plenty left in this car, I wouldnt think SEVERAL tenths are out of the question.

Hate all you want, we've had several cars do very well at the track this fall....

That's the normal response from EPL. They blame maintenance first, and if you've done your maintenance then they move on to telling you that you need carbon cleaning... then when you tell them that you've done carbon cleaning already, they forgot what they said the first time and tell you to do maintenance. lol

basically, they don't want to work with you. Buy the tune and go away is the vibe they give off. They still haven't even invested in building their damn website.

Not the case at all. With LC I could do 1.7 or so in the 60' as I had a really awful start with over 2.0 in the 60'. My 118-119 trap speeds are the same people are doing with 11.4-11.6 1/4s, just having a better launch to drop the 60'.

I thought traps typically drop with lower et’s and 60ft. I’m not an expert on 1/4mi though.
Either way maybe you have the only car here that runs well on EPL so thats good.

I agree with several tenths off using LC but not half sec difference on same tune.
I’m not hating and would be impressed if I were proved wrong on this btw.

I posted on your thread. You really should have tried the MPS4S before swapping tunes for a fare comparison.

[DGVR6]

Someone really needs to step up for Uni.

I’m sure they’ll put down some good times.

[Randy Mintz]

I have the Unitronic 1+ for my 2019 A5 2.0t, Unitronic is the only dealer locally. I have not measured specific times but the overall feel of the vehicle is much faster and the speed limiter is completely removed. So far loving the improved performance.

I was running the 91 file on both, we don't get 93 in WA.
