How To Chip a MK3 VR6 ~ DIY Video

[@hozerdee5993]

Yeah i chipped my MK3 to delete the secondary air pump and the second O2 sensor .. Never regretted it , love the way my car runs now !!

[@270billycraven]

second 02?

I know I’m way late but can you please tell me what product you used?

[@famadrid78]

Thanks Charles, just got my chip from reflect time to teach my old dog a new trick. Thanks for your great videos on this platform

[@Ryl33hz]

just got a Reflex Tuning chip for my Mk3 VR6, runs soooo much smoother than the GIAC previously used. Highly recommended.

[@NahshonWebb]

I see this chip getting around now especially i just seen this vlog from chrstian smith doing a decent preview of the chip. Ive had 95 vr with the garrett chip and wanted to know the difference. There was a timenwhere giac was the shit and the best chip for the vr. Being that you went from giac to reflect tuning.. you feel its more power? Garrett boast to this day 12 hp and tq respectively. And does it really rev out to 7500 rpm as to garretts 7200? Thanks.

[@RelaxingVibes202]

What are the advantages of this chip?

[@thatgtguy6729]

You are the best online mechanic by far! I'm thinking about buying a mk5 gti and I'm so glad i found your page! I can not thank you enough for the advice and information your throwing out there for free and its good advice not joe blow in his shack. many many thumbs-up!

[@HumbleMechanic]

+thatgtguy ! Right on man. Thank you very much.

[@jp8ksynth]

Great video. Did you notice any performance gains from the chip upgrade? You should always use an ESD (Electro Static Discharge) mat when working with electronics or circuit boards. The last thing you want to zap the ECU or any part of the board.

[@tommyb8046]

i see alot of people suggest an anti static work surface. the only suggestion i would have is to keep that seal good and to help it a little bit.....a thin layer of di-electric grease works wonders. Also great for your main harness plug in to keep any water from getting into a plug with an old seal.

[@euroglx]

Cool video, reminded me when I chipped my 97 Jetta GLX with a GIAC chip. Made a world of difference.

[@HumbleMechanic]

I think it needs a few bolt on mods to really shine.

[@euroglx]

+HumbleMechanic I agree, I had few when I installed the chip.

[@taiwilson8966]

chip combo with exhaust is nice on that motor

[@ridiculousness7477]

Am I the only one who thinks that isn't the best place a ECU should be placed?

[@HumbleMechanic]

+freelan89 you're not the first to mention it. But everything worked out just fine.

[@domzcollesso9070]

wont water get in there?

[@ferfire9]

No, it has a draining system that makes water go to the sides of the car, no water gets in there, only dust and stuff.

[@jeremyjohansson3445]

The Mercedes A-Class had the ECU right on top of the engine. In order to change the air filter, you have to disassemble the ecu. Haha I hate that car

That is absolutely on the list!

[@guidosaur7506]

right. I just did the same thing

[@ridiculousness7477]

@@HumbleMechanic hoping you can help. I bought a chip for my obd2 12v, followed your instructions (thank you). But the car doesn’t start with it. The check engine never illuminated once the accessory lights came on. I swapped the stock one back in, the car started. What gives?

[@alfbittner6489]

Great vid, but what exactly does this chip do?. Is it a tunning chip, or is it a performance upgrade, how much HP increase. I might have missed something, or does this chip just allow you to clear fault codes?. Can you get a performance chip off your guy, might be a cheap HP increase before the turbo goes on.

[@nikeelm]

it looks like its used to cancel out codes ...not performance related

[@user-dn6qy1ou1f]

You can clear basic codes like that with most any scan tool. Vcds is used to get access to everything the dealership can. Im guessing it was a performance chip. He just didn't explain what it altered

[@alfbittner6489]

I've recently changed my a/c pump, to do that I removed the front end, it was an easy procedure and accessibility made the job easy. Long story short I popped a header tank hose and the temp warning light came on, fixed hose, drove car and it died three times. The last time a friend with a scan tool did a code clear and it started and got me home. When we went to drive again no start. Is this what you meant do a one key cycle, to make sure the code doesn't come back, and what if it does.

[@nicknicu1787]

Awesome video dude! 10 thumbs up for this one!

[@HumbleMechanic]

Thank you so much. :)

[@jockbad]

I wonder if this is the same for the MK4 AFP VR6

[@bstevenson1002]

What's a good ECM I should get for my 04 GLI 1.8T. .. looking to gain more HP......????

[@gglovato]

those PLCC chips, so retro!. BTW i'd also check the state of the capacitors whilst the ECU is open, a while back iirc on Toyota cars bad caps where failing the ECUs(there was a recall or something), doesn't hurts to check and it's an easy repair. Also, that chip mod is easy with those socketed ROMs, newer ECUs are more complicated sadly :( About VCDS, love it but it's crazy expensive, and they seem to have cracked down on chinese copies(there where bulk of them on DX, now i can't find any)

[@Robert-vi6tb]

Hello i just started watching your videos and you are the Man, specially be cause i just got a VR6 Jetta 1996 and its my project car Do you think i can be able to rebuild the engine by my self ? i already know how to remove the motor and transmission off the car watching your video. congratulations for your Chanel i am a new subscriber And of course i wanna say thanks for all the information and knowledge you share here!

[@billyp.7889]

It would be nice; if you would do a review of the wireless HEX NET, version of VCDS. Many of us; have the cable for years but have not made the leap to the wireless version. So far, from a cost effective point of view; I still think the VCDS License with HEX-USB+CAN Unlimted VIN (All VAG), is the best deal (although being tethered to a windows based laptop is a drag). It would be cool; to use a phone or tablet, however.

[@HumbleMechanic]

I will. Some of the wifi is still beta. Well at least on the app. But it's pretty awesome

[@bbirgersson8639]

Why just a 2.8 😁 mine is a 2.9 ABV 4WD 1996, now it's a 3.0, 264 cams + 2mm valves and a straight 2.5" exhaust, did it my self. 😁

[@RAA12586]

I did this the other day and found a giac chip installed from a previous owner, my plug had lots of broken bits and did not disassemble as easy, now my check engine is back on again. At first I though it was because the connection wasnt secure, but I've been driving around with no driveability issues.

[@stanwilson8089]

I have a 1999 VW golf mk 3 1.9d,will it benefit from a new chip? (or does it have one?)

[@dereklacy]

Great video, quick question though. Is a TBA needed when swapping chips? Also, what does a stock chip look like? PO of my car is pretty sure it's chipped, but I think it's stock.

[@katanamd]

PLEASE work on an electronic safe surface. When I was putting a new heat-sink on a computer part I was also using a micro fiber rag. While working I felt a little shock, that $300 computer part was toast.

[@Ms.Fowlbwahhh]

Modern electronics are pretty good about static. Still always a risk. Iv done that a few times (even smelled a little smoke) but it still worked.

[@SasukeGarage55]

I have a question can I relocate the ECM, I really never understood why Volkswagen put it there

[@AGuysGarage]

Good video thank you for sharing. Is the ECU located in the same place on a MKIV Jetta? I have a 24V VR6 that i wouldn't mind chipping. ;P

[@HumbleMechanic]

It's in a similar spot. But I think on your car, it's a flash not a chip replacement.

[@PeekaSnipes]

In the 2 month since you installed this chip did you see a noticeable difference? I don't know much about all the different brands of chips, but for $100, and within the website description, it seems decent. Thank you :)

[@HumbleMechanic]

Other than I have no check engine light, not much. But this is a stock car that needs some maintenance. It will really shine when I get an intake and exhaust. :)

[@PeekaSnipes]

+HumbleMechanic Fair enough, I'v got an exhaust/intake.. getting rid of that secondary air code would be cool :)

[@augustriveira]

I have been watching your video and really like them. I am doing some research and would like to know what you think. I have a 2002 Jetta Wagon with VR6. I have been discussing doing some modification with others who own VR6s. I was told that the stock engine can handle 400 hp all day long. I utubed vr6 stock engine with turbo and found 400hp turboed cars. I know I would need to upgrad the fuel system. I only want 320 to 350 hp. Would a chip and injectors work? I sure wish you were closer to Washington State and see if you would be interested in doing a show on stock engine upgrade. Anyways any input would be appreciated as I completely trust your knowledge about these motors..

[@Jonq360]

does this work for digifant 2?

[@jonathanhernandez6878]

Pardon my ignorance. But what are the benefits of changing that chip?

[@GarthGoldberg]

Did the fault code have anything to do with the chip swap? Or was that an existing fault? I'm not sure I see the point of connecting the VCDS other than clearing the fault. Would the fault have cleared otherwise?

[@HumbleMechanic]

It was an existing faulting the main reason for the chip. It's always good to check faults after work like that. Many failures are 2 trip monitor failures. That means they need to fail a test twice to turn the MIL on. But you can often see the fault stored before the MIL is on. This may help prevent an issue while on a test drive. Think about the drive into work @6am the next morning and the MIL pops on. I'd rather know I have an issue while I am at home or the shop. Rather than wait until I am on the road.

[@schuldiner01]

Should definitely be wearing an ESD bracelet when doing this kind of work.

Good Video, what's the performance improvement on the Chip? or was this just a repair job? Thanks!

[@HumbleMechanic]

Thanks. The chip has an estimated 10hp gain. I don't really notice the improvement while driving. But the car is stock. You can feel that airflow is somewhat stifled. I think with an intake and exhaust it would be very noticeable. The main reason for this tune is to solve a check engine light issue due to a failing secondary air system.

The factory says its at only 200hp stock but, i saw one dyno'd stock at 211hp with only basic mods. KN Filter, royal purple oil, etc

[@trevorfaulkner4934]

Did you reflash your ecu in your 24v? I see Malone Tuning has reflash sale until the end of the year at ECSTuning that will net something like 15hp and 20 tq and for under $300 I think it's worth it.

[@Jacksonkellyfreak]

Hey Charles, on the wireless OBD cable, do you have to have a VW specific cable or will one of the $20 generic bluetooth OBD adapters on Amazon work?

[@HumbleMechanic]

It MAY work, but my gut says no. It is looking for a wifi address and I don't know if the generic ones will have what it is looking for. I think the wifi is great, but it is pricey. I think for most folks the standard cable is the way to go.

[@Jacksonkellyfreak]

+HumbleMechanic Even still laying out 100 something for their proprietary connector is better than the cost of the software. If it works on wifi, then it's probably a definite no because most of the generic ones I've seen are bluetooth

What part of the latch would actually be bad? The only thing I can think of is the contact switch in the rear hatch mechanism.

High impedence (peak and hold) line driver. Running 850cc or 1000cc injectors? Definitely the way to go. Adaptronic has some units starting at 850$. For 1350$ you can get an 8channel high output unit(m2000) that can make your VR idle way better than stock even with big/fast injectors. Use a narrow spray pattern on a single valve.(12valve). Standalone has autotune have no fear. Run and do anything you want. Convert to drive by wire and direct ignition.
