Was expecting to be just fine since I took a "safer" route with a more expensive Powerneedy catted downpipe but unfortunately, it's throwing a Check Engine light so now I'm going to have to take the car back to stock or buy a JB4 piggyback tune... But more importantly, I might need a new engine

Happy to help 🙏

@suprola7961 3 года назад

It sucks. Toyota made this car to be modded. It was advertised as a moddable Supra for the enthusiasts. Then one year later, they beefed up the power and locked up the ability to tune. Sorry about your oil issues. They should have left the 2020 B58 in there.

@ajburke801 2 года назад

Great video very informative.. I have A 2021A91 Built-in July so I'm locked out on the tune also. Installed a cated downpipe sounds great and the check engine light goes on and off. Check the gasket on the oil Pan for oil consumption

@elvis_chen 2 года назад

Some down pipes are well calculated with the air flow and able to cheat the ECU to avoid the CEL e.g. Rushplux. I have it installed for several months on my MY21 with no CEL at all.

@Powaup 2 года назад

Yeap! I have friends with AA that are very happy and no CEL. I bought the wrong brand

@evlx14 3 года назад

Great video man, very informative. Did you have to load any sort of tune when installing the catted downpipe? Do you know the power gains with the new downpipe untuned? Thanks!

@Powaup 3 года назад

Thank you! I didn't tune my car but I've seen other do the same and get ~20 whp on the dyno afterwards

Going to be dropping my car off at Toyota soon to get the oil issue fixed and since that'll involve warranty work I've decided to take my car back to stock.

@thebritish910 2 года назад

I have the oil issue on my 21 too. Service is refusing to say there is an issue, just telling me to get an oil change at the maintenance periods. What did you tell them to get them to take to seriously? I have had many cars and a bmw in the past, none burn through oil so fast.

I’ve read from others that they still get the warning light. That said I was able to clear the CEL by putting the car in maintenance mode so should be good from now

@kelvinmejia8384 2 года назад

My 2020 has a catless downpipe and the check engine light came on immediately lol. I want to flash tune it but I’m afraid of voiding the warranty for other things that can go wrong on the car, even though I own it out right that warranty is key. especially for the next owner if I sell it.

@Powaup 2 года назад

Warranty will be ruined if you go too crazy but as long your local dealer is mod friendly you should be fine with small mods

@bigneutron77 3 года назад

Your gas cap was probably loose, and I got the jb+ and by the ass dyno, you definitely feel a difference. If I could compare it to anything would be a sneaky peek nos system.

@Powaup 3 года назад

It’s happened twice the CEL coming on (again right after this video) I was able to clear the CEL by putting the car in diagnostics mode though. Glad to hear you have a good experience with the job plus. Once I get the whole engine thing sorted out I’ll figure out what to do about tune/exhaust

@edwint1780 3 года назад

The JB4 will definitely add at least 50whp to your supra on a 91 octane and about 80 whp on a 93. Doesn't matter what the starting hp is, 380 or the 335. The 2021 supras have lower compression pistons so you can run more boost than the 2020, so the jb4 may actually be even more effective on your car than the 2020 as its main means of adding power is by increasing the boost.

@Powaup 3 года назад

Thank you for the info. Do you happen to know if there is a “linear”/low torque map with the B58 JB4? That was my go-to when I had the M4

@edwint1780 3 года назад

@@Powaup There isn't a map that's made specifically for the linear power delivery. Supra's stock turbo is very small and quick to spool up, which inherently results in the powerband where a bunch of torque gets dumped all at once. The piggy back tune won't be as refined as a custom dyno tune, but ultimately, those who want a more linear power delivery need to upgrade to the pure 800 turbo. That will smooth out the power delivery.

@user-vj8gm3dn1i 2 года назад

Hey Edwin, you seem to know a lot about Supras. Is the 2022 Supra gonna be flashable? I heard its locked just like the 2021, but what are our odds?

@skywalk3x 3 года назад

I have a 2021 Supra down pipe, cold air intake, exhaust and Ecutek stage 2 tune. The first month or so I got the CEL light, and then it just went away. Ecutek has a clear that I used for the CEL but I haven’t had one for at least 7-8 months. The newer Supra’s can be tuned ThicWhips has a video showing the Company who has the tune. Also the Supra’s no matter what year will get, will get CEL.

@Powaup 3 года назад

Which intake you go with? I watched Thicc whips video recently, very excited for that ECU flash to become available (mine was built passed the cut off date). Enjoy the Supra!

@skywalk3x 3 года назад

Mate, any luck with getting the CEL out? - I got decat Downpipes and it's throwing a CEL - cleared it with a OBD but it cam eback again, will try a spacer out this weekend to see if that helps

@Powaup 3 года назад

Catless downpipe will constantly throw a CEL. Only way to keep it off is a tune. My downpipe has a catalytic converter but I still get a CEL but not as frequently

Hey mah man, I had a catless downpipe and got state reffed and just today I put pack on the factory downpipe and I want to know how long it’ll take for the Engine light will go away??

@Powaup Год назад

It’s really hard to determine. Typically if you go for a drive and keep the running for like 30 minutes it clears. But your best bet is to get an OBD2 reader and clear the code. I’m sorry you got state Reffed I know it’s a very painful process. Good luck!

I bought a 2021 with a build date of 03/20. My car has gone through 1/2 quart in 2,700miles (4,100kms) I've had zero track days, and I never beat on it. I'm wishing I bought a 2020.

@Powaup 3 года назад

Damn it... well at least you can ecu tune yours if you want. By the way. I’ve heard one count of a 2020 car with oil guzzling issue so maybe that some of those cars are affected

@beexiong2995 3 года назад

Did you try to wipe the code in diagnostic mode? You have to be in diagnostics mode to clear codes.

@touayaaj84 3 года назад

I run a catless Euromotive dp and i have a cel too. The cel does no damage to the supra. Just keep it on.

@Powaup 3 года назад

It doesn’t but I can’t get your car serviced at Toyota with it on and it’ll hide any real problems if you always have it on

@DBABAE 3 года назад

For clarity, the date that actually matters is your ECU date! The build date does not always coincide with the ECU date. Check this date first, your car may still be tunable 👍🏻

@Powaup 3 года назад

How do I find the ECU date?

@DBABAE 3 года назад

@@Powaup search “ecu 2021 Supra” on RU-vid and there’s a couple videos showing how to! It’s very simple, just pop the ECU cover off and unhook it and pull it out slightly and you can see some numbers which coincide with the ECU date

I think the whole Jb4 thing is trash. Such a pain in the ass to install and doesn't even allow full access to features. Only gives you little more boost. I have a supra and love it but its just not a car I even want to mod at this point. I would just do cat back + rims and leave it alone.

I’m in the same boat. Mine was built 1/21. I’m debating on running the JB4 myself.

It’s annoying because watch. Soon as you buy the JB4 then BOOM someone unlocked the ECU. At least that would be my luck

@Kiteboarding316 3 года назад

You should have a tunable DME. Just need an unlock. Check the Manufacture date on the DME and reach out to Visconti Tuning.

@micahhill4786 11 месяцев назад

See here’s the thing with high flow cats. I have one I’m my old turbo Hyundai Elantra for 4 years. Every now and the check engine light will come on for the high flow cat. The aftermarket cats do their job but not as good as the factory cats because the high flow cats are made to be well high flow. So it doesn’t filter out lot of stuff on the engine but it does get rid the gas smell so that really what matters.

@jaywalker4206 3 года назад

You’re incorrect. It’s not when the car was built. It’s when the ecu was built. If the ecu was built after 6/2020 then it’s locked. Check the ecu build date on the unit itself.

@Powaup 3 года назад

Thanks for the help. Someone else noted that early but unfortunately my ECU was still born too late

@tgshark1 Год назад

Key points here, all of our parents grew up without cats...next prove climat3 change is caused by cars...next you can easily put on defoulers to avoid a CEL on a catless dp....

@trd_ftw Год назад

Fast forward to 2023 and JB4's are every where. The stepping stone before going and getting a full tune! Not to mention the turn around time to unlock the ECU takes about a week, leaving you with out a car for that time.

@chrisginoc Год назад

As a 2023 6MT owner, I would rather do the Femto unlock for MHD or BM3. I've heard so many bad stories recently in reference to JB4.

@trd_ftw Год назад

@Chris G Full unlock are expensive and often leave your car unusable for about a week. Unlike the JB4 that will give you a quick little something while you build to bigger and better things. All stepping stones.
