thats not a tune or fuel issue.... most likely one of these issues!

Boost Pressure Control Valve (N75) faulty
Boost Pressure Sensor (G31) faulty

Just googling and stating that it is one of these items without knowing our platform isn't helpful. Our turbo wastegates are electronically controlled with an actuator, we have neither of those valves. An overboost could in fact be a tune issue, but might also be a wastegate issue (or even a DV issue). Unfortunately with Unitronic you have no way to log parameters (another MASSIVE downside) and as you can see a response "It's your gas." is incorrect and also unhelpful. That's just poor customer service.

Cobb won the game. If you are choosing another tuning platform at this point in time you aren't paying attention and wasting your money.
 
Preaching to the choir, IF I could leave Unitronic and get my money back I would have :mad: Logging is a MUST that we still don't have and they have said nothing in Months.....:screwy::screwy:

lol not knowing the platform..... if you own a vag vehicle and dont have ross-tech aka vagcom thats just silly, you can log and figure out 98% of the issues with vagcom and clearly if its a mechanical issue then you got to take stuff apart and inspect.... I highly doubt this is a tune issue and its forsure not a gas issue cause then he would have knock and timing pull so which would give less boost and go into limp mode!

I have a HexV2. It's great for coding and scanning, not great for logging. It's sampling rate is too slow and worsens as you add more parameters.
You told him to replace parts that don't exist.
 
TCU update to Stage 1a ?

I was checking a few days ago for any Unitronic tune related DTCs using UniConnect, and noticed that there was a new TCU flash, called something like Stage 1a.
Anybody know what changes that might include and why?

You might want to ask Unitronic what are the changes. I checked mine last night. The cable got update, but I don't see any changes when connecting to my 2018 R. My tune options are still the same.
 
DQ250 TCU Stage 1a update

For everyone's edification ;)

"Hi Carson,

Thank you for the email. The file Rev1a has adjusted shift points. It comes down to preference. I would recommend trying the file to see if you prefer that file over the original one that you have flashed.

If you have any other questions, please let me know.

"Adjusted shift points" seems kinda... vague.

Yeah. But as far as I know, Unitronic hasn't released info on what their original Stage 1 shift map was, so nothing to compare the Stage 1a map against even if they'd given us details. If I have a gripe about Unitronic, it is the amazing lack of product documentation - would it kill them to have a product revision changelog?

I've flashed TCU 1a on my 2016 DSG R, and it works, no issues so far, but I haven't driven it enough yet to notice any possible seat-of-the-pants differences.
 
No updates from Unitronic is months.... Unitronic Golf R VII development over..........RIP:wave:
My S3 and R buddies switched from Uni to EQT to get an E30 tune. Whomever is running Uni has zero business sense and the marketing and communication presence is appalling. The crappy communication and 'new tune for turbo inlet' lie (and other faux pas) along with other none releases erode their brand like salt on a slug. The Mk8 release is on Nov 4th and these clowns never even got to their R exhaust and turbo upgrade after 5yrs. I'm not a capitalist by any means but a company that can't follow through deserve to go under.
I don't see any presence on here or other forums to defend their position and provide positive PR.

Couldn't agree more. Unitronic wont be getting any more of my business.

EQT is actually who I was leaning towards. I'm a little shy about doing any ethanol mix tune right now but may just go for it instead of going to a 93 tune. How do you feel about it so far? What are the PROS/CONS? How big a pain in the ass is it to mix fuel? What are some of the cost associated with switching to EQT (hardware/software)? You can private message me as to not hijack this thread but I bet some other guys on here may be curious as well. Thanks!
 
Man why all the hate for Unitronic lately. Been super happy with stage 2, yes there are those waiting for stage 3 and bigger turbo's etc...I get it but seriously, I have not had a bad experience yet other than what has been caused by my own stupidity. I for one am glad they do take the time they do to get things right, even if it takes longer. Been waiting forever for the MQB Tiguan tune that just came out but they said they were working on it and they delivered. If they were developing for just the Mk7 they would be bankrupt, there are other platforms and they all need their share of attention and its a pandemic so we've had a lot to deal with this year. I'm not sorry that my Tiguan development or my friends RS3 development this year took away from you guys getting stage 3 on the mk7.

It's simple economics too folks, most mk7s are out of warranty now (those earlier purchases) so bigger turbo's and tunes are starting to make sense. I know we're voiding warranties to some extent anyway going stage 2 but a newish car that had a warranty and jumping to stage 3 could be drastic....we all pay to play, but some are just more willing than others to take higher risks, that doesn't mean all of us are. I will go stage 3 as well some day, but I'm working my way into it and still enjoying a dependable daily driver....for you track stars, I get it. Maybe Unitronic isn't the brand for you then. But why smear them? Of course they aren't going to respond on forums that are bashing them.

To top it off with the likes of the American tuners getting slapped for emissions and ending downpipe and other development, you should be happy there is an option still out of Canada.

I do however agree that it would be good if Unitronic had a way of eblasting owners about their software update; with details of the changes, who its for, what it changes so we can make an informed decision. Not much different than updating your Operating System except we don't keep the unitronic cables plugged in all the time getting auto-updates...some sharing would be good though.
