Guys who knows is anti-lag system safe stuff for these supras particularly b58 equipped ones ? I'm councious that lag is almost unnoticeable considering how good are modern turbos but even though for example some folks are looking forward to install one in these supras will it harm them on stock rotating assembly?
JB4 is fantastic. They’re relatively cheap, but provide great gains. Truly a bang for the buck. They even make one for the 1.4t jetta that gives it an extra 30hp over stock
I regularly have my stinger running 22psi up from the standard 15psi stock...running with water/methanol system...Bluetooth app and functions. No issues at all.
This was my dream car but the more I look into the ecu lock down vs the extent of upgrades/tunes I was going to introduce I'm more and more turned off. Rather buy an old chassis of something and build it completely from the ground
Femto does full unlock now with BM3, mhd and mg tuning. Bm3 also has updated gen 2 release now... anti lag, flex fuel, map switching, etc... For all gen 2
Buddy of mine had a 2020 M4, threw a piggyback on, ran semi decent but then was later told bmw would still be able to find out. Lmfao. He was scared for his life.
Some of you act like being a bmw is a bad thing lol. Bmw makes some of the best engines ever made. One of the selling points that actually make me want a supra. B58 is amazing!
@SupraSav as sweet as that would be, I really don't see bmw giving up the s58 and having the supra take away sales from their M cars. I'd love for it to happen, but unfortunately I just don't see it anything more than speculated rumors. Will probably get the updated B58tu2 that's currently in some of their 7 series cars.
@@SupraSavrumor has it Magna Steyr is going to be retooling for EVs soon. Little chance we'll see BMWs i6 king in these cars. Not to mention, their $180k racing spec GT4 only has a tuned + modded b58 with a whole bunch of weight loss producing a whopping 450hp. Something you can achieve with the JB4...
So, my local performance mechanic warned me about the JB4 when I inquired about turning my 21 supra. He had at least 4 mk5's with blown engines due to people using the preset tunes that come with unit, apparently some of them are a little too aggressive out of the box, so please be careful about using this option. Currently the FEMTO unlock is around 5 thousand bucks and sending your ecu to Finland and back while my car sits dead is a lot to ask for. So, for me, I'm being patient. It is only a matter of time until more companies figure out how to break the encryption on the ecu, which will, in turn, reduce the cost. Just have to avoid software updates and the dealership and wait. Nothing is better for reliable performance than a professional tune done in tandem with the proper parts.
@homiefizzle5260 no idea, but people forget no two cars off the line are truly identical, and the Mk5 is not the exception. Some of the B58's have been reporting an issue with burning oil is a great example. Some are fine, and some have the issue. The JB4 is a budget option, and sometimes, you get what you pay for. Car modifications are always somewhat of a gamble and can have unsceen or unintended effects. A good mechanic and quality parts can help mediate the risks, but remember, there's no guarantee in the car modification world.

Mazda is having the same issue. Apparently COBB is having an extremely hard time cracking the ecu in the new turbo mazda 3 so it can use the accessport. Why cant they juat let us have fun and enjoy tuning our cars??

Lmfao, so you’ve got to spend 50k on a car for it to not be tunable until you spend another grand on it, that’s this bypass ecu and a tune. That’s tough.
Here's a fairly slow bmw with Toyota badges. Good luck having fun with it cause we locked it. I swear it just destroys the very spirit of what a supra should be.

Basically Bosch stopped a tuner car being a tuner car, Toyota/BMW need to use a different supplier
BMW was the one that forced Bosch into it
From what i understand its related to strict emission standards
Its to pass emission standards to sell the car
it was probably ordered by bmw or toyota XD
BMW’s fault. The car is all bmw.

berserk reference??????
Plenty of people making 470-480 rwhp on just a dp and JB4 (map 6 on E30). Easy low 11 sec 1/4 at 124-126 mph. Many have done it, and it's cheap :)
Are they gonna do this with the 2024
About half of the words you said i didnt understand
I wud just safe up for Haltech Elite standalone ... done
Your first mistake in going fast is buying a slow car.
Supra mk5❤
Is the 2021 Mazda 3 hatchback locked?? I have it and my mechanic can’t figure out if it’s permanently locked from factory.
Bosch…. How.. Dare.. You!😅
Love it
I’d love to have a mk5 I prefer them over the mk4 tbh
What about a fully aftermarket ecu would that work?
Tuner called femto…….that’s metal af.
as long as it's not the 4cyl. then just sell it right?
At this point, think I’d rather just strip the factory ECU out and go standalone. Sounds like it would remove so many headaches and hurdles.
How is the JB4 on a manual?
Why go faster? I would not be doing any ECU mods to it until warranty expires
They cant afford fast cars so they buy slow ones and tune them.
I have a Supra stock and is plenty fast for me
Just buy a new ECU at that point, much easier lmao
How much horsepower do you need for the road? Is the stock ECU not good enough?
Oh shit I used to live right down the road from you guys
Many manufacturers say the same thing. Give. It. Time. The code monkeys will crack it eventually.
Disclaimer on the jb4 although it’s reversible if anything happens warranty will not be covered due to going over parameters of car

Dually noted.

My dad has a jb4 that were installing in a m550i
Oof. Bmw v8s arnt it. Tell him to save his warranty 😅. If he wants to go fast tell him to get an m340
JB4 is great but bm3 is a world of difference. Way more gains on bm3
Good thing we can unlock our cars cuz the way they gate the power is crazy stupid

Rule no 1 :- first buy a supra 🗿🗿
I’m still thinking if I should get one or just get dodge charger srt
Send it to femto? Guts would kill me.
How is this the only comment that read berserk
Bro every time I hear femto I can only think of berserk 😂
Do not use JB4, yes you’ll gain horsepower but it doesn’t adjust for fuel cuts and safety protocols. It’ll just increase boost.
Okay $40K for an extra 18 HP!
$40k might not be worth 18hp but what about $1750 for 140hp?
