CJAA TDI: Stock VS Stage 2 tuned
Вставка
- Опубліковано 30 січ 2025
- Up today we're tuning a CJAA TDI with MR Tuning stage 2 software and Powergate V3 flasher. Covering off reading the stock tune to send out then getting the new file and uploading then comparing fuel mileage and 0-100 km/H.
Another great video Josh, my 13 JSW is getting the same tune next week after I hit a pot hole.
Definitely wakes it up, too bad they couldn't of came this way from the factory
Been thinking about getting the Mrtuning tune for my 05 Golf BEW. Seems like a good deal, plus I like being able to change between 2 different tunes. Loved the video.
The price is definitely enticing compared to Malone, I’ve had good luck so far just. Thanks
How do you change between 2 tunes?
@@JosephEaorleit’s switched on the fly. Drive is 25hp and sport is 55
This is with all emissions still on?
Will the tune work if the car has had the VW dieselgate fix? Will a DPF and EGR removal help with the power increase? Very informative video, thanks Josh.
Yes this car had both parts of the dieselgate fix. This is straight piped, I’m hoping to throw stock tires on and re-run the 0-100 tests again.
I have a CJAA Jetta Wagon with a Malone tune and Rawtek hardware. Wondering if I need to fork over another $700 to MR or Stevenson to get a smoke tune for a party trick?
Im not real familiar on the smoke limiters on these, i'd imagine they use both the MAF and lambda sensors making it hard to "trick" the ecu into adding more fuel
@@JoshsJettasit's 100% doable. You can shut off the o2 sensor completely (many tuners do this, some like Stevenson keep it in place and active) and mass air flow is just mapping and maps can be edited.
After deleting my DPF, EGR and both cats my glow plug light is blinking just like in this video, however, unlike this video, installing the tune file did not turn off my glow plug light. Is there something else I need to do?
Tagging in for answer.
@@GunsNBudder So I think I answered my own question. The first tune I tried was a stage 1 25 HP tune. I tried again with the stage 2 55 HP tune and the glow plug light stopped flashing. I think the stage 1 might only be for vehicles with the emissions intact. I have yet to try the stage 2 25 HP tune but I'm guessing it would work. Now I'm wondering about their new "Econo" tune and also there is supposedly a way to run the 25 HP tune in Drive and the 55 HP tune in Sport mode, but I have bugged their tech support so much this week I might try that next week.
@@JosephEaorle how many files did they send you? I only got a 25hp and a 55hp which I assumed was their stage 1 and stage 2. I never tried the 25 hp tune myself but it should’ve been tuned for “off-road” use.
As far as the 25hp and 55hp switch on the fly “sotf” tune it can only be done on auto cars and requires dsg tuning. D mode is 25 hp and S mode is the 55 hp tune.
@@JoshsJettas They sent me 4 files. "Econo," "Stage 1 25HP", "Stage 2 25HP," and "Stage 2 55HP." After installing the Stage 1 25 HP my glow plug light was still flashing. I emailed Martin about it and he told me that one is for emissions intact only.
@@JosephEaorle When switching from 25HP to 55HP tune did you have to flash to stock first? I am currently running the 25HP tune and want to switch over the 55HP file.
Thanks for these great video's. Any downside to using the 55whp rather than the 25whp tune in regards to turbo longevity and fuel mileage?
mileage shoudnt change much unless your using all that power difference at every red light. As far as longevity i think it just runs 1 psi more, but they keep it within safe limits. Pretty easy to get a bad name in the tuning world if your making the engine/turbo run outside of their limits
Hi Josh, watching your videos and also doing research about diesel jetta's. My main goal is to get a 2011-2015 TDI jetta and aiming for very good gas mileage and range (1000+km's of Range) with good reliability. I don't care about how fast the car is but I don't mind the extra power and torque the tune would give. Mainly focusing on the good gas usage. I've read up on deleting the car and other little tips and tricks. Could you recommend anything to help me reach this goal on this car? Also some questions: Does the tune with the car deleted improve gas mileage & is the price cost of the tune and deletion of the car worth it in regards to improving reliability and fuel economy? would appreciate the help. thank you!
There is a gain when just tuning the car, even more so when deleting. Car doesn’t have to run as hot to regen, runs at optimal performance and don’t have emissions components or sensors to fail. I did a break down on mileage pay back at the end of the video, pays back even faster if you have a component failure
Hi Josh do you know if I could read stock file and continue driving the car until I get the mod file back?
Yes, it’s just reading the stock file not editing it or anything.
I got the tranny DSG tuned first then I got the engine tuned. 55 hp. My fuel mileage increase crazy. If I drive it like and old lady, I'm in the high 4's liters per 100... 120 to 130 kms 5.3 ish.
like it shouldve been from the factory, makes a big difference
So no DSG tune? Our 3 Jettas have Stage 2 tunes and required DSG tunes.
No, MR Tuning requires it after stage 2, not sure how they make it all work.
Is obd2 readiness monitor set to ready after the tune?
ill have to double check but i believe theyre set to not applicable. So should pass emissions as all monitors are set to either ready or no applicable
@@JoshsJettas Are you saying that a deleted TDI can pass emissions tests in places like St Louis or Chicago that require emissions tests to register your vehicle? The tuning file is sensing when the vehicle is being tested?
@@JosephEaorle depends on how they test. If it’s strictly obd test looking at monitors it should. If it’s a visual check of components then it would fail.
Why is the glow plug light flashing??
Lack of dpf/egr/cat and related sensors
@@JoshsJettas that was deleted in the tune?
Yes it was an “off-road” stage 2 tune.
my glow plug is flashing too after deleting and did not go off after the tune, am I missing something?
Nevermind I did a stage 1 tune. After I did stage 2 it stopped flashing.
Hi Josh! I have a 2013 Golf TDI 6MT and am planning to buy a Flowdirekt kit since I am in Quebec and it would be easier to get it..Can you please tell me where to get that powergate tool and if I can do the tunning safely at home...I then only have to find a shop to install the CR140 delete kit. Thanks in advance
Are you located in Quebec as well & can you do the install for me?
Im in Southern ontario, fair ways away. Everything can be ordered through MR Tuning though, theyve updated their website so it can all be ordered there. Theyre in quebec as well.
@@JoshsJettas Thank you very much Josh! Here is the situatiom: I was away for 6 months and left thekey to my neighbor who was starting the car every week or 2 for 10-15 min...After I came back on Dec, the DPF issue (which I never had after it was replaced under warranty in Aug 2021) arose and made seriously consider deleting it...After countless regen cycles, the car that was at first driving like a block of cement, drives smoothly now, but the light comes back everytime after I start the car (along with a Nox sensor related check engine)....Few seconds later, it disapears and the check engine remains on the dash...! Would you do the delete for, because the job has to be done by someone I trust...I got in touch with 3 shops and they quoted me form 1200$ to 1700$, but when it came to tune, they said they will be using custom tunes (i.e., None of the ones you mentioned, alias Tunezille, MR Tuning, Neurotuning,...), so I can't trust them with my car...I can drive down there to get ot done! Thanks
@@DustyPearl-13have you followed through? I’d come to your place and help you do the delete. It’s only a little bit of a pain just need a battery tender, computer, and some patience for the component removal. Did my CJAA and would never look back the milage is amazing
@@dsrta645 Thank you very much, but I sold the MK6 TDI with 315000 km last march and got a Honda....I am planning to get a BMW X5 35d and get it deleted...I will let you know...By the way I live in Montreal, Quebec, Canada
@ not familiar with those both always willing to lend a hand. Southern Ontario for me right by the border let me know if you need a hand I’m sure Quebec has some nice beer as an incentive!!!
Should i install the tune before installing my exhaust and deletes in case the file doesnt work? Im about to tear apart my sportwagen as well.
Yes get the stock file sent out and get the modded file on before removing stuff just in case. I haven’t had issues but you never know
@@JoshsJettas would it be fine to drive with the tune and my old exhaust still as I would have to install the tune then drive it to my shop
@@timeandspacevintage3380it will have a CEL but itll be fine for a short drive. It would destroy the emissions equipment quickly but you're getting rid of that anyways
@@tylercorrigan228 my emissions equipment is already destroyed lol
Yeah a short drive will be fine, it’ll plug the dpf somewhat quickly though assuming it’s not cracked already
the engine is stock?
yes stock engine/turbo
@@JoshsJettas and 255 HP will not damage engine? i mean. pistons, crankshaft and connecting rods will it withstand such a load?. i have aslo jetta mk6 TDI "cjaa" engine and i just think about tunn up.
@@amex13 it’s not 255hp, you get +25hp or +55hp over stock, I think they say you’ll be around 180hp with the 55 tune
