034 Owners Discussion Thread

[Ashtonts]

Hi, I wanna upgrade from stage 1 to stage 2 single pulley. Some questions:
1.) I notice there would be different pulley ratio depends which pulley you go for. So stage 2 file covers all the single pulley options/pulley ratios? How does it work?

2.) If I go for 190mm crank pulley(PR≈3.0), is it still considered mild? Cat safe? It's my DD, wanna keep it quiet. I only WOT once in a while.

3.) Do I need a hx upgrade? According to the website, it's not necessary, but I live in Hong Kong(90 plus degree and very humid), maybe a different story?

Thanks in advance

HX should be required for anything stage 2 and above IMO. Even stage 1 you would probably benefit from it.

PR 3.0 isn't too crazy aggressive. Cats seem to be a crapshoot. I was fine for a while on a much more aggressive PR than that, but some blow their cats on stock or stage 1 tuning. Just be prepared to pony up to relocate them if necessary, but it's likely you'll be alright.

[hunter_killer]

I’m running that set up (stage 2/ 190 crank pulley) I would highly recommend a HX. Mine keeps warm even after a few back to back pulls and I’m not in that humid of a climate in the summer. If you don’t go with a 190 crank but say even a 187 that stage 2 tune will cover that pulley size as well or if you went with a s/c pulley instead you’d be alright as well. Longevity you will be fine on that setup, like stated your cats may live or may not, but keeping it cool and properly maintained will surely help everything out.

Thanks for all your replies. So the stage 2 tune will cover pulley ratio from 2.8 to below 3.2 or something? It adjusts according to the air drawn into the engine? Sorry if this is a silly question.

[hunter_killer]

Yes you should be just fine. Make sure to get a HX to handle the heat and the tune will adjust to any of those PR’s.

Since your setup is similar to what I want, can you tell me the difference from stage 1? Have you done any dyno? I couldn't find any stage 2 with the 190mm crank pulley. Thanks a lot

While I didn’t have an actual stage 1 tune I did have a Chipwerke set pretty much to a stage 1 tune with the same mods and for nearly most of the daily driving there really isn’t much of a difference, but the real kicker is when you get above 3k rpm the stage 2 tune is night and day alongside the TCU tune as well. I haven’t done a dyno and probably won’t as there isn’t a local awd dyno. 034 has a chart for crank hp/ tq so using that with the rough 15-20% drivetrain loss will give you a good idea. I have a few dragy runs but I’m still getting the launch right without losing traction. My setup has been good enough even with heat soak to beat a C6 corvette and 2nd Gen CTS-V twice a piece at roll racing.

Got a few questions for either 034 themselves, or members here running their tunes (or both):

1) Regarding the TCU tune, I noticed there are 2 options for shift points... one with 7200rpm shifts across the board, and the other with staggered shift points (1st - 2nd: 7200, 2nd - 3rd: 7300, 3rd - 4th: 7300, 4th - 5th: 7500). I am running the dual pulley E40 tune (3.25 ratio)... which one would should I select if my goal is the quickest E/T and mph?

2) I noticed in the first 15 pages or so of this thread, there is mention of some people running an E50 tune... is this something that's still available (either by email request like their meth tunes or...)? Perhaps this was something that eventually evolved into the current E40 tune and no longer exists?

3) Finally, I've read 034 uses some input from the secondary (rear) O2 sensors in their tunes. Is this true? If I gut my cats and install spacers, will this throw off the tune and potentially decrease performance?

Thanks in advance.

I thought that most, if not all, tunes read from the secondary O2 for the purposes of fuel trims. This will need verification.

EPL says they're friendly to O2 spacers. They will NOT disable or code out any emissions items for legal protection reasons. EPL said the federal government is hitting tuners with fines, and EPL said they don't want that risk. Plus, they say when the car is resold that there's sometimes emission compliance between states/owners and it's been administratively tougher for them to handle that and help owners bring those cars back into compliance.

034 however, WILL code the catalyst codes out to avoid a CEL. This is done automatically on their test pipes tune. They encourage people to NOT use O2 spacers (as they want accurate readings from the O2's to have accurate fuel trims). I think this is the highest performance, safest way to go. It is the most legally risky. 034 is in CA, so I worry for them a bit.

Simply put: If you gut your cats, and have a 034 tune, DON'T install spacers.

Do any 6MT drivers (other than myself) not like the 034 pedal mapping? I have excess jerkiness (drivetrain lash) in 1st and 2nd at low speeds. The stop-and-go driver life is pretty rough. Seems to occur in both Comfort and Dynamic.

I just sent James a request to ask for tunes without the 034 performance pedal mapping, and allow the OEM mapping to be retained.

It's been discussed before by Javad on a Q&A pretty recently, because another user had a lash issue. Basically, it was brought up; but, they seemed to didn't think it was too necessary since nobody else really complains about this. Also, I posted about this earlier in this thread, and Sean replied to me with more info, if anyone wants to find that and read more.

I'd like to stay 034 tuned because they're actively supporting the JXB fuel system that's still in development; but, as of right now, the mapping is a deal breaker for me. It's just specific to my car and cars like mine with tolerances apparently big enough to create lash. Not 034's fault. It would help if they had an OEM pedal as an option, though... I'll post James' response when I hear back from him.

I do NOT want crackles... and I believe all 034's test pipe tunes have crackles built into them.

I have to pass inspection every 2 years in my state, so having no CEL and all the readiness tests passed is a must, so that's another strike against the test pipe file (if it truly tunes out the codes). Unfortunately, spacers and the non-test pipe file are a must for me for these reasons.

Same thing happens with the DSG tune. Comes with the territory but it’s something I’ve learned to deal with and not that big of an issue anymore. I’m sure the manual may be a bit more known and I think I recall them saying in that video they weren’t going to change the throttle map that correlates to the drivetrain lash since there’s “nothing wrong with it.”

I also don't like the throttle mapping of the 034 tune.

I assume they use it to make the tune "feel" more responsive, but in reality it makes driving at low speeds exhausting.
I would trade for the OEM throttle maps in a heartbeat.

Iirc there are test pipe tunes with a +no crackle option. Double check on your flashloader

Coming from EPL, to me the throttle mapping is much better. I’m not noticing a huge amount of drivetrain lash, certainly not to the point of it being “exhausting” to drive. If I notice any, it’s pretty easy to tweak my driving to get around, and I had the same problem stock and on EPL tuning.

I am NOT at this stage yet, so my answer is purely based upon my research

1) The test pipe file does come with crackles but only when the Engine is set to dynamic mode. If you run Comfort, or an individual setting with the engine set to comfort, then you'll be good! No crackles!

2) outside of the crackles, the only other difference between comfort and dynamic is a "very slight" (034's words) difference in the pedal mapping. They say it's hardly noticeable, so an individual profile should be fine for you on their test pipe file

3) the test pipe file eliminates the CEL, so it'll allow you to deal with emissions. It eliminates the requirements for spacers (which lie to the ECU about readings, and can throw off trims). I live in an emissions county, but my car is registered at my house that is not... So I haven't been through the emissions process yet without cats.... I hear this will be your solution, though. The caveat would be if you live in CA which has CARB now, and before they had a "sniffer"

Keep in mind eliminating the CEL doesn't necessarily allow readiness to set if you are in an OBD emissions testing location. That could still cause you to fail testing if more than one monitor isn't ready, and the eval monitor is almost impossible to set in the winter.

This is true. From what I have read on these forums emissions testing standards very greatly depending on your location. In MD I'm allowed 1 readiness sensor to be no set. That is usually the evap. I just saw a guy on the 034 FB page pass his emissions test in DC while running 034s test pipe file which does not force readiness.

With this engine if everything is happy and healthy the higher RPMs will definitely improve your times and MPH. I would switch to the higher shift point file.

The E50 tune was something 034 was playing around with in the beginning of their development. It became the E40 tune that they have now. An actual E50 tune doesn't exist from them. They have said before that E40-E50 is the range people should be targeting. I just think if they called it a E50 tune for marketing people would run E60+ and you would probably see more engine failure's.

3) Finally, I've read 034 uses some input from the secondary (rear) O2 sensors in their tunes. Is this true? If I gut my cats and install spacers, will this throw off the tune and potentially decrease performance?

This is true , 034 wants the secondary O2 directly in the bung without spacers. I have never seen seen or heard them or anyone quantify how much performance would be affected by running a spacer. From what I have seen the ECU uses the secondary O2 for LTFT and the wideband O2 for STFT.

I didn't notice a difference between Comfort and Dynamic. I flashed back to EPL yesterday, got caught in stop-and-go, and the low-speed drive is SOOOO much nicer again... I'm within the 034 30-day return window still, and I might have to send it back. For my situation, it's honestly a tough decision for many reasons.

I do understand why 034 doesn't think it's a problem, because it's mapped to feel sportier, more responsive, etc. Yes, it is a feature; unfortunately, it's a feature that affects "certain cars" and mine is one of them.

Coming back to EPL, EPL's pedal does feel "mushier;" but, it's something I feel like I can live with and I'm already used to. I almost wish there was a "immediate middle" between the two, and I feel like that would be perfect.... Either that, or a way 034 could turn off their enhanced pedal mapping below certain speeds.

My main problem is when I let off the throttle. The car just goes UGHHH UGHH UGHHH. lol

f1torrents, is your issue off the throttle too?

[sampaul]

While I didn’t have an actual stage 1 tune I did have a Chipwerke set pretty much to a stage 1 tune with the same mods and for nearly most of the daily driving there really isn’t much of a difference, but the real kicker is when you get above 3k rpm the stage 2 tune is night and day alongside the TCU tune as well. I haven’t done a dyno and probably won’t as there isn’t a local awd dyno. 034 has a chart for crank hp/ tq so using that with the rough 15-20% drivetrain loss will give you a good idea. I have a few dragy runs but I’m still getting the launch right without losing traction. My setup has been good enough even with heat soak to beat a C6 corvette and 2nd Gen CTS-V twice a piece at roll racing.

Yeah, but the numbers on the website were for the smaller supercharger pulley stage 2, I believe. And it's been a while. Plus I think there is a difference when you increase the pulley ratio from 2.8 to 3.0.
I'm really looking forward to see your dragy runs, especially 0-60 mph
Thanks.

Yes, it is off throttle.

If I'm going slow and lift off the car wants to lurch forward, it's almost as if I have to keep a little throttle applied so it won't do the lurching.
It makes driving in a neighborhood very uncomfortable, and exhausting.

EDIT.. BTW I also have a 6MT

I remember watching a video where he was talking about drive-train lash, witch this is not what I am feeling. He said they could make a file with the factory throttle maps.
This would be ideal for me.

This issue became more apparent to me recently when my daughter started learning how to drive MT using my car in a parking lot at very slow speeds. It was jerking quite a bit. I realized I’ve been using the clutch pedal to offset the issue, engaging the clutch slightly to keep it from jerking around. I’m not in stop-and-go traffic often enough for it to bother me but I can understand where you are coming from.

[f1torrents]

James from 034 replied to me today and said they have no plans to FIX the throttle mapping.
But may FIX it in the future.

We have to pressure them into fixing this and offing the stock throttle mapping.

I know a lot of people complain about the lurching, chugging, and I believe some are even misdiagnosing this as DRIVE-TRAIN LASH when all it is is bad throttle mapping.

James is going to ask Nate and the team again. I sent them an email last night on my decision... Basically I'll keep the 034 tune if they allow for an OEM mapping, and they decide not to adjust it I'll return the tune and keep EPL for the meantime. I mean, they're both really good tunes in my book. I just prefer 034's model a little more, and like that they're working with JXB on the port fuel system upgrade (which I am looking to get at some point - TBD). James basically said he's got me covered, even if I run a little over my return window.

James has been great on fielding my emails BTW. 034's service is solid.


Just out of curiosity, were you the guy who basically brought all of this up to begin with? The reason for that Q&A video, or is that a 3rd case of someone who feels like we do?

[f1torrents]

I did not initiate this. I am just another case.

Not only is this issue something we are dealing with, but I believe all of the customers that "think" they have drive train lash and are blaming that actually don't realize its the throttle mapping.

I have been much less please with James at this point. Telling me I need more seat time to get used to it.
More seat time will just end up with me puking due to the jerkyness.

Its a horrible map, I'm not asking them to recreate one, just give me the stock one back.

[mahhdd]

The problem is that there's a lot of tune files to keep on top of and update, I imagine.

just a thought - maybe your dmf is worn if you're still on a stock clutch and this is exacerbated by more aggressive throttle map.

Nothing is worn.

Why not load a beta file on MAHHDD or My profile and let us test a stock throttle map as a test bed?

Because 034 is out of there BETA program . These files are finalized . What ever revision they release now are for internal bugs .
And not to come off the wrong foot but was it necessary to create a individual thread for your individual issue ? 034 has publicly stated the reason of your experience.
Have you tried to flash a 91 or 93 (visa-versa) to cross analyze ? Last lastly , low miles don’t exclude any mechanical issues either ... just saying .
