Can This Cynic Be Convinced By A Tuning Box? Ft. 520BHP BMW M4 By TDI Tuning
Вставка
- Опубліковано 22 лют 2019
- I've never been a big fan of the M4, I think most people know that. So I was very curious when TDI Tuning invited me to try their remapped version, fitted with one of their in house tuning boxes.
More than a simple sensor defeat, this little device talks to all of the car's sensors to continuously deliver a "remap", but the car never knows it is there. However, I thought the standard car had way too much power and torque - has this just made it undriveable?

Hello Everyone, for those of you who want more information about TDI-Tuning, have a look at our channel where we release videos about development cars including dyno runs and acceleration runs. We are constantly developing maps for the latest makes/models being released in the UK and around the world. Please get in touch for more information.
Lots of ppl on here don’t have that box and talk crap like they are some pros , in reality they don’t know what they’re talking talking about ! I just got the box and I’m very impressed!! The extra boost is unreal, I’m even suprised I didn’t expect it to be as good. Technology is definitely evolving in the automotive industry and what these boxes can do these days a remap would do maybe for way more money $ ,
I remember the good old days, when you would pay perhaps £500 for basic mods on a car and get maybe +5 bhp (if you were lucky), or £2-4k on cams/manifolds/exhaust etc. and get perhaps +30 bhp.
I don't miss the good old days.
John timken yeah those old Model T’s were a nightmare to tune.
@@Stabby666 True, but a 10 year old T was repairable. Modern electronic wonder machines will be uneconomic to fix as the expensive faults develop and multiply. I owned a 10 year old Mitsubishi gto, never again will I buy a supercar, it cost me thousands. Give me a wave next time you overtake a model T.
@@johntimken9842 GTO hardly supercar status friend...
Hi Jay yes after watching LLF and seeing his M4 fitted with one, I said yes let’s give it a go and had one fitted to my Audi S5 convertible and my god what a difference!! Absolutely love it 😍and what a professional company and install . Highly recommended 😁👌🚗
Great video, loving the additional camera angles. Keep up the good work 👍
Excellent impartial review , well done !
A very well thought out product and a great price point I've seen a few videos on this box inc Rickys LLF think the guys at tdi tuning are genuine petrol heads and have invested a lot to get it right. Great video keep up the hard work.
Thanks Chris
Cracking video James, cool car but I'm an AMG guy😃. I really love your style of presenting so down to earth and informative 👍
Cool sexy drive by shot :D to be honest it really does add to the video, I dunno how hard it is to do those shots but certainly makes your content look a league ahead.
Very hard is the answer lol
Well done then, looked really cool apart from the obvious piss take of trying to look cool bouncing to the music with your hand at the top of the wheel :D
Very informative👍 I have been on the fence with attaching one of these to my SQ5. I just might take the leap.
absolute zero did you do it?
Brilliant again . Good time. Don't need more than 500bhp . If anyone wants more and more , better to buy a more powerful car. Perfect power and great review. Little by little you WILL be a BMW fan
Bootmod3 is the way forward for BMW tuning. Do remember Jay that BMW can always find out that one of their engines has been mapped. They have many ways of confirming this and there is no way that this can be hidden from them.
A tuning box isn't a remap....my fathers brother own a tuning company... boxes leave no trace... ECU will only record that the boost has spiked but won't know how because the boxes go after the ECU.
I’ve always mapped my car I think it’s a must
What’s it like , left in a setting after time does the ecu pull it back in line ,with time ?
Be good to see a dyno then some mileage covered then the dyno results again all in the same setting ?
Problem with that is environmental variables
I had one of these. Didn't always work. Random power spikes. Kicked in at different revs. Then went MRC custom map. Much better
Was it a TDI branded box or another?
@@JayEmmOnCars tdi sir. When it worked the difference was big. But it was so spiky and random I had to get rid.
@@MT-kx2uc . Way more torque. But wasn't consistent. Randomly kicked in. Big spikes. Sometimes didn't work.
You get 30 days if you don't rate it anyway, no lose product really.
Jay E, LLFast UA-cam gone approaching 800ps m4 turbos Holland. Got knows what feels like
I can just imagine the knock control going mental in the M4 with tunning box. I'd never fit a device like that to a turbo petrol car.. Whatever about diesels, but petrol... Time will tell
Would you ever tune an Evora 400 or is it a waste as the gearbox is the limiting bit anyway?
I'd go for a Komotec 460 kit and take the chance
For an extra 100ftlb shouldn’t that be a kick up the arse compared to standard regardless of how smooth it is? Maybe it didn’t come across in the vid or i don’t appreciate how modern fast stuff do their business.
Looking at the dyno graph it appears to be closer to 480hp?
What an incredible bit of kit. A lot of tuning options can be a bit Halfords, and ruin the looks, sound and driveability of a car (not what you want to do with a lovely M4) The fact that this looks completely standard just adds to the appeal (screw insurance companies!)
@Ron P if it's easily removable I wouldn't bother, insurance companies take the piss (and I've had over 20 years of that!) The only time I've ever had them inspect the car, they didnt turn up for 2 weeks so I would have had plenty of time. Obviously, if it's obvious it's been fitted then tell them, we all know those pricks will wriggle outta paying any way they can.
@Ron P yeah you're right, it's just my experience with insurance companies has never been anything other than a pain in the arse. We've all spent a load of money on insurance and the times that you actually need their help they drag their heels when paying out. I had someone reverse into my car and smashed my door and rear quarter panels in. The insurance company that I claimed against did nothing but mess me about the whole time, with the insurance inspector guy talking to me like I was an idiot. I was fairly young (very early twenties) and was driving a ten year old Astra GTE and he did nothing but slag the car off and seem like he was looking for a way to not pay out. I've crashed before (my fault) and it took them ages to pay out, it was only a cheap second hand motor, so we're not talking big money! Again, they messed me about leaving me with no wheels for way too long as I needed the car for work. I've had plenty of other bad experiences (i can only remember one occasion when they were helpful!) and paid out loads of money to them. They're very quick to take the money, not so quick to help!!!
@Ron P yeah, you are right. They just @#$% me off haha!!! With some other young UA-camrs doing crazy mods to cars, doubling standard power etc, I wonder if they declare the mods. That IS insanity, as they often detail EXACTLY what theyve done to their cars and drive like nutters on public roads. I dont think it'll be long until we get the first of these UA-camrs crashing at huge speed into someone killing them (or themselves, or both!) and the police will have all the evidence they need for a conviction on the UA-cam channel.
@Ron P I really enjoy Living, but I can see it ending badly for him one way or the other. Those motors they are belting along in are staggeringly quick, in a different league to me and my mates doing 120-130mph down the motorway (and that was dangerous enough!) These motors must be getting to the 200mph mark, and getting there incredibly quick. It would be a different matter if they were belting down an old airfield or whatever, but this is on public roads with other cars. I've got a wife and 3 kids now, and drive a shitty Focus, but I wouldn't take it kindly if one of these guys plowed into me. The police have nicked people before by IDing the road being raced on, and then timed how long it takes to e.g. go from the bridge to the 3rd lamp post, the coppers go and measure the distance and then it's easy to know pretty accurately how fast these guys were going. As you mention, everyone wants to be UA-cam famous nowadays and are often willing to do very silly things to get there. In my naughty earlier years, we wouldn't dream of filming any silliness because if the law get hold of it you've basically nicked yourself!!! Although a nicking would be better than a fatality.
Interesting. Anyone tried TDI's map for the Smart Roadster?
Need to do remap vs tuning box race as 400 is remap money really
Can it finally keep up with a Guilia now? :p
Put one on my BMW X3 M40i and noticed absolutely zero difference. I noticed no increase in power, and after driving several 200 miles plus trips on different settings and then with it off fuel mileage was within 1/10 of a gal. So essentially it did nothing. I would love to see someone actually post a real dyno with one of these. I seriously doubt more then 15-20hp if that. About all this can do is increase fuel rail pressure. Now I'm having trouble getting a refund under their 30 days policy which I met.
all these boxes add marginal bhp, its pointless
Just been to a rolling road day. Audi a6 biturbo diesel without tdi tuning box 320hp. With tdi box on 315... remaps not boxes...
@@MT-kx2uc the dyno showed the ecu was fighting the box all the way through the revs. Didnt like it at all.
What is the insurance hit with one of these boxes?
Kraken1000 as if you would inform the insurance company
I like the packaging of the 4 convertible, but it’s way too heavy and I prefer a soft top, and I prefer NA with a manual. E46 then, but it’s one of the least rigid convertible chassis, you can’t win.
The E46 vert is also very heavy
TDI is an unfortunate initialism for a performance company
I know right lmao it genuinely puts me off
🙄
Don’t like tuning boxes unless it’s for warranty purposes a remap is much better
The problem with adding more power to standard parts is that more power equates to more stress and more wear on parts. This is the reality, parts will wear more and therefore break more often. Might still be reliable but parts will break more often.
Kuddlesworth NA in a car that new it won’t make much difference. I bought a bora at 133k remapped not long after and it still going 25k later
@@Birmingham_racing It could be in 10 years time or tomorrow but when you run more power through anything it will wear more. Only way to tell is to either inspect the parts or to have an oil analysis done. Chances are everything will be fine but there's a good chance you will see abnormal wear. I would like to add that BMW or any engineer isn't thick they would know straight away weather or not a cars output has exceeded a normal un-tuned state. Especially when you increase power output by about 100HP which is a rather large increase.
Kuddlesworth NA all depends on how your treat it but it’s worth the fun
@@Birmingham_racing Absolutely.
@@Birmingham_racing bora 1.9 PD130? My dad and uncle have the same car but standard. My uncles one has around 180k miles and only thing he's had is the turbo veins sticking which was temporary fixed using Mr muscle oven cleaner and recently my dad changed a part of the auto gearbox as it wouldn't change to second gear when cold. Forgot the name of the part he changed but it was around £300 and luckily fixed the issue.
Don’t cars need to be custom tuned on a dyno though to ensure power delivery is a smooth curve?
Depends who's behind the laptop
Will Maddox can you explain? A generic map is not a one fits all is it? I thought each engine performs differently and as such a custom tune on a dyno was needed to ensure a correct power curve?
Yeah that's something I've heard also. Like you said every car performs differently even when comparing the same car and engine.
I was looking at a remap company which can add 30hp to my 1.6 diesel engine. For £150 you can send the ECU off to them where they map it.
Recently the main guy now has a place in Bristol which can now do a live map by reading the cars parameters through a laptop and map it accordingly. This for £200. Sounds better to spend the extra £50 and get it down there.
Zain K HDI tuning ?
it's fast yeah?
This below link was a good watch I thought. I wouldn’t have one, for example whacking up fuel pressure as a work around to increasing fuelling sounds like a terrible idea:
ua-cam.com/video/QNu17zA1sRg/v-deo.html
Does this tdi box work the same way?
£400 is a remap price. Never fit a tuning box on a decent car. Get it on the rollers pay a bit more, and sleep well in the knowledge that it’s safe 👍
Nice video though.
If it's a new car on finance and you take it to the dealership chances are they'll reset it back to factory settings. Remaps good if you own the car or it out of warranty.
Remaps nowdays are reversible. You can flash your ECU to its original settings in minutes.
I dont remember the M4's problems being a lack of power.
Can you remap the M2 Comp. also?
You can, don't waste your money on these tunes. Bootmod3 all the way. Ecu flash is 1k x better.
All about the numbers for bantz more than actually needing the extra power at those figures.
I do like those mirrors!
Box that fudges sensors and bumps pressures, would rather remap the actual ECU
Don't you get it?
Interesting they quote 520bhp with this box. I had my 435d on rollers at Surrey Rolling Road (great result 410bhp) and a guy had his m4 there with a tdi box. On the rollers his car made 495 bhp. No where near 520bhp. I think to get 520bhp on an m4 you need catless downpipes and a proper custom ecu tune
Or fuel additive 👍
Tuning box’s are really bad for car when it is cold
Get the numbers off a dyno these tuning boxes never create more than 10-15 bhp more
Get one then talk, till then be quiet.
TDI-Tuning must have paid you at least 2,000 pounds for this video.
They didn't pay anything
shame james, I was looking forward to getting an "unbiased" opinion on this tuning box, until you said the car was not yours !!!! come on james, you CANT recommend a product like this, how do you know T.D.I TUNING have not carried out a whole list of modifications to the car without your knowledge, IF you had put the box on your car and YOUR car only, this would have been a good review...……………………………...
You will soon have a review of a car not owned by them
@@JayEmmOnCars luvvly jubbly
@@JayEmmOnCars ...so.....when you "do" review this tuning box again, this "will of course" have been purchased by your good self with your OWN funds via a online website, it WONT be a freebie supplied by the manufacturer, will it ? I'm not having a dig at you, your human, like me and EVERYONE LOVES a freebie .... But when freebies ARE given, neutrality goes out the window and favouritism creeps in ,it's extremely difficult to remain TOTALLY unbiased when you have a 500 quid given gratis in your mitts, true or false ???????
It's not my car it belongs to a friend. Honesty is important to me and I have always bern very clear and open about what I have been given if reviewing anything - it's up to you if you decide you don't want to believe me
@@JayEmmOnCars so "your friend" will have purchased this with their own funds? I'm NOT accusing you of being dishonest in ANY shape or form, just asking for a level playing field....is that fair comment ?
This is a waste if you're out of warranty. Bootmod3 all the way. Why have to trick your ecu when you can actually flash it and get a smother power delivery and more power.
Yer right 100bhp from a box 🤣
Yeah, that's exactly how it works
@@JayEmmOnCars ok if u r so sure get one for any one of ur cars and get on a dyno
@@andrewpattie358 I mentioned in the video at the time, none of my cars would work with one anyway.
My least favourite M car unfortunately, particularly in convertible form. I don't know if it's just me but these turbocharged 'M' engines sound crap, particularly from the outside. Like a chavved up Focus ST with a 'popping' map.
I agree with you entirely
S65 and S85 engines are much more characterful. Cannot ignore the performance available from the current M Power turbo engines though.
@@jackthehat8593 Totally agree, the performance is eye-wateringly impressive but in my opinion it's actually *too* much power (Never thought I'd say that..!) . I'd sooner rather have an E46 M3 and be able to exploit all of the power on UK roads and not have to worry about spiky torque delivery upsetting the balance and traction at the rear. The problem is them pesky hot hatches making 300bhp, the M cars have to up their game proportionally.
@@spainter1985 hammer meet nail meet head. 100% agree, though I aren't an M3 man myself, having owned two E39 M5's and currently having an E60 M5, admittedly broken 😂. I would quite like an F10 M5 but I aren't 100% sure why as I really like the v10.
I have an F10 M5 tuned by Evolve and dynoed at a gnats cock under 700bhp, decatted . A twin turbo 4.4L V8 certainly does not sound “crap” to me, and the performance is way ahead of any of the old N/A M cars (of which I’ve owned several). If you consider over 500bhp “too much power” it’s time to swap your man-card for a pair of slippers...
I've got hair like your's just not on my head James. Can we have less Bmw and more Jaguar ready for Brexit. lol
I asked Jag. They said no.
Shame about your T shirt. I love Eminem ; )
Zzz
seems boring as hell
"Silly straight line antics" perfectly describes this type of pseudo testing. In a world where you often get what you pay for, this £400/100bhp box beggars belief unless accompanied by video inserts of dyno evidence or other product developers data. Frankly, this presentation and its sycophantic references to TDI Tuning cannot but give the impression of desperation for channel content.
The dyno printout is shown in the video
@@JayEmmOnCars My bad - I couldn't endure the complete video because of the seemingly endless non-technical waffle - apologies.
@@JayEmmOnCars Oh, and by way of comic addendum, the waffle regarding the power increase was akin to the sequence when HAL, the computer in the movie 2001, when it was being disconnected, "I can feel it...I can feel it, Dave."
@@voncoconut5293 can you give us a link to your car channel? It must be great as you're obviously a cut above JayEmm.
@@johntimken9842 Now, John, that's just a plain silly remark. Does one need to be a cook to critique food or be a pilot to fly the Atlantic?
Well, Cletus, even though you're a walking advertisement for Pedigree Chum, this wasn't a dog's dinner. Boom, boom‼️
On the other hand, with your haute coiffure, you definitely have a whiff of the canine haute cuisine.🐶🐶🐶
From the way the graphs mirror each other, it looks like they've only increased the fuel flow. More fuel means more torque; power is a product of torque and revs, therefore, more torque at the same revs gives more power. The actual distribution of torque and power are nearly identical.🤔🤔🤔
It would be instructive to compare fuel consumption between the various "tuning" devises.🧐🧐🧐
It's a shame that a great channel like yours is being polluted by Brexit buffoons.🤬🤬🤬
