DRIVETRAIN MALFUNCTION

[Jodace96]

I just bought a used 2020 3.0 SUPRA A COUPLE MONTHS AGO

this is my first turbo car, apparently the car came with a tune e50 and downpipes, but the owner took some parts out, intake, charge pipes , flex fuel , ecutek key , i have been driving a little aggressive to be honest , and yesterday when i hit the gas the turbo did like a weird noise, not the same whistle as usual , and since then whenever i do 5k 6k 7k reps and the car shifts the car goes a little down and shake, today i just got a notification about the drivetrain malfunction, i went to the dealership and the suggested me to go to a European car shop to get fix, or the car would lose the tune and i might need to buy everything again around 1.5k

anny suggestion?, the car has 30k miles, im a little scared that could be something really bad

This is why you don't buy tuned cars second hand. Because they're beat on and half the time the "builder" doesn't have a clue what they're doing, and breaks shit and then sells the car. When it goes wrong you don't have warranty (probably) to fall back on. It's a very expensive lesson to learn. Your best bet is to take it to a dealer and let them fix it, and hope it's not too bad.

Did you buy it from the dealer? They should be able to get on it. Possible blown turbo?
if it’s blown, Ill buy it from you. But you need to get an upgrade/ replacement and tune.

If you have anything to create logs with. I suggest making one and reaching out to a tuner. Or even posting it somewhere for all to look at.
Best of luck!

I’d say let them flash it to stock. You’re better off going completely stock and spending a bit more to know the tune and everything that’s on it then keep guessing. Do you even know if the car was tuned back to regular pump gas or if it was still tuned on e50 and which fuel had you been putting in it?

Go easy on OP, what's done is done. Possibly limp mode from overboost or something. Impossible to know with out the logs.

This is it. Have the dealer flash it back to stock + diag. Lose the tune, you don't want it anyway, you don't know anything about it I assume? Especially without the dongle, you're in a tight spot.

Flash it back to stock, get the actual codes read, then spend your own cash on the tune, new ecutek setup (or BM3 or MHD or whatever).

not to be pessimistic but i hope you have a few couple $$$$ on standby. Sometimes you can be lucky and just get away with a reflash of tune or flash back to stock, but judging by how it sounds, sounds like the car was ran thru before.. i'd say retrace the cars steps by putting it back to stock w/ stock tune. If the car is still acting up, then you have a problem, if everything is resolved, slowly replace the old parts back in and work your way up from there. Good luck OP

Best bet as mentioned, is flashing the car back to stock. You don't know what tune is on the car. So you can start fresh. Then diagnose if there are still issues that remain.

Precisely!

Also if you’re using the ethanol blend are you sure you’re not tuned back to 91 or 93? Or even vice versa if it’s tuned on pump and you added e50
