Malone has sent a new tune and requested I re-flash.

 

Weird they would do that if it wasn't "the tune" huh?

 

He will reflash and his ECU will be bricked. "Oh you must have flashed it wrong."

Why would you say such a thing!?? 😆

Reflash went well. SOTPD (Seat Of The Pants Dyno) says its more lively. Could just be a placebo effect though. No CEL so far. Guess we'll see how it goes.

Here is this mornings log

Nice.... the struggle was real.

 

7 days, 400 miles. CEL has remained off since the reflash.

Guess I'll call it "fixed".

Thanks for the help all. 🍺

/thread.

 

So that settles it.... it wasn't the tune

 

Did you use the tunezilla "autotuner" service?
I'm not driving mine at the moment, just finishing up rawtek install. I made up a egr cooler delete which works good but on the first couple of cold starts after reinstalling everything I noticed under a bit of load the engine was misfiring and blowing blue smoke probably from fuel.
Maybe some air in the fuel rail as you have to remove bridge line. Seems to be ok now

 

tunezilla "autotuner" service

Dunno what that is?

When I purchased the flash a ticket was opened with support. When the CEL came on I replied to that support ticket indicating I may have an issue. Waited until my VCDS came in, got heckled here as I fumbled through figuring out how to get a good log recorded 😝, then finally uploaded that log to the support ticket. They wrote me a new file and I then I reflashed it.

 

Yeah you got it.
"Autotune" is just a bot that takes the hardware/software version log and matches it with a file tuned with everything you asked for and you download it. I noticed my 2014 Jetta file is actually taken from the ecu and tuned rather than just a log file. The CP14 ecus seem to have more anti-tuning checks that the CP44.

If you want custom software for a different setup you go with a ticket system and wait in line. Or like you had an issue with your tune.

Nothing like a good heckle, as long as you are willing to take it feel free to give it!!

 

Ah yes. That is what was used on the initial purchase.

 

Another reason why they are called "canned" tunes!

 

Instead of starting a new thread I thought I might join in on the fun. Well I just finished delete and installed tune. And guess what?

Since we're on the "fun" aspect of things, would you guys get all sideways if I were to $hit talk your canned stage whatever tune and deletes that are making hot air instead of power?
Have a look at your IATs!
I bet your EGTs are also crap!
How much coal are you rolling?
I've attached a visual of my stock setup, while attempting to find a similar data point so you can see the difference!

 

No worries tagging along. Good to have multiple data sets in one thread.

Tuner is going to want to see the graphed data when you contact them.

Good luck.

 

Have not looked at them but now I'm curious so i will.

 

I'm not in the business of shaming a company, I give a company one chance to fix the issue but after that it's no holes barred. It seems like this is an ongoing issue as its becoming apparent that the "autotune" bot isn't dialed in properly with this ECU.

I'm not mad but I do want it sorted. It's not my primary vehicle so it's not going to effect me much right now.

As for smoke, it's cold here and I was driving at night so while I noticed a cloud , it was probably more condensation than smoke. All I know is a guy in his Dodge ram looked angry when I gapped him good at a set of lights last night during acceleration test. Bad sport flipped the birdy when he lost... no surprise there.

 

Anyone wonder why @Dannyboy485 IATs are 21deg C above ambient vs my 6dec C above ambient at similar speeds\boost parameters?

 

Probably driving the pi$$ out of it caused that, it was in the city but in an industrial area. I was checking everything was in working condition. 0-100 then sitting at traffic lights

 

You believe it's "heat soaked" at -10c ambient and still not scrubbing the "soak" off at a velocity of 96kph?

 

No I believe the charge coolers need to be cleaned because they are filthy but washing them at the moment isn't an option. Couple that with an over boosting turbo I know the recipe equals high IATs no doubt. I'll be logging some data later if I'm not going to have a few weekend beers

 

Just have a look at them. I don't like them, but I don't like the EGTzzz as per @ValveCoverGasket
Lots of others are OK with 930c EGTs and never look at IATs.
I think these canned tunes make a lot of hot air, and they give you the extra grunt down low for the "holy it's fast" feel while putting a lot of heat into everything (turbo, oil, coolant, pistons, etc)

You're in the industry, so you know what heat does to everything.... just raising flags so you can avoid damaging your stuff.

Don't trust anyone.... only trust data

I agree with you 100% , heat and metal fatigue go hand in hand. I wouldn't allow my turbo to reach a sustained 930c as that shaft is going to cook anything that touches it at those temperatures, namely oil. Which will screw the journal bearing.

I haven't had the opportunity to take the treg out properly to log it as ive been fixing up my 2010 golf tdi which is going to be my son's surprise bday present as he's been eyeing it up for a while.

 

Oh how I miss my CJAA

 

Ive got two. I'd much prefer the golf to the jetta as it's a way better build car but previous owner never took care of the exterior so every handle and door corner has rust.

But wont get rid of the 14 jetta because it has only 90k kms on it

 

Dannyboy485,

Have you tried their stage 1 with deletes or stock with deletes?

Curious if stage 1 will request less boost and not cause the overboost or the problem is related to the deletes.

 

The problem is 100% the tune. Sceep has had the excat same issue. I've heard it's not just Club touareg members that are reporting this issue. I have a VW tech buddy that also heard the same issues

 

That's nice to hear, hopefully it will be fully resolved with a revised tune.

 

So the main lesson is Malone tunes can no longer be trusted? Too bad- I really enjoyed the one in my 2000 Golf TDI.

 

Malone is FAR from the best tuner out there. He just happens to be an easily accessible tuner. I've been saying this for a decade.

 

Today i didnt get overboost codes but I'm not going to just leave it as is. Waiting for support which isnt the quickest by any means. I'm not batting for malone but he does make some very good tunes. However I think his divergent company "tunezilla" has issues that need to be sorted out before he starts getting a bad name.

 

@Dannyboy485 & @Sceep
Here's a fresh log off my OEM setup so you can see how pressures behave before tuners get to them.
Log #657259

I've removed the other data plotted since I'm the only EGTzzzz fanboi around here.

 

930c is not safe for any CR that I'm paying for.

 

People have been running that in far less engineered diesels for many decades now. Short bursts are fine. Hell, diesel pullers run much hotter than that.

 

Don't be a sheep. The info is out there if you want the truth.
Start by reading about how the piston shape differs between a tractor and a direct injected diesel.

Uhhh you know they pull with light duty pickup motors and tractor trailers too, right? I know the info. Been building diesels a very long time since a mechanical rack 12v Cummins was in the stable. Short bursts are fine. Aluminum alloy has an even higher melting point, which most European diesels have used since the 90s
