First Tuned (ish) 2022 Tundra

Link to the write up:JB4 for Toyota Tundra 3.5L Turbo - N54Tech.com - International Turbo Racing Discussion

Was able to borrow a 2022 Tundra today for a few dyno runs. The truck is all stock and was running equivalent of 93 octane.

Stock it put out a respectable 321whp and 352wtq at a peak of 10psi. We expected a little more given the factory rating but you never know until you strap it down and see. After a couple baseline runs we used the new JB4 Tundra BETA to dial boost up to 15psi and were rewarded with 369whp and 410wtq. Really nice delta for the mild tune. Timing, afr, fuel trims, and throttle were all nicely in check. I'm sure the platform has another 20whp+ in it when we're ready to push things further.

We've got a few more loose ends to tie up in terms of adding CANbus channels and then we'll add the Tundra JB4 BETA to our website

That didn't take long.

Edit - photo looks like those tires look a bit larger than OEM. The torque number is a really nice bump.

 

321 does seem a bit low for a stock truck on 93. I would have expected >350.

 

I wouldn't put too much weight on those numbers as the method they use to measure power vs how toyota does can be drastically different, the gains made is the main focus imo.

 

Im more speaking in reference to the rated power and what we see out of 3.5L Ecoboosts. The 2017-2020 3.5L was putting out just over 350 wheel with 93 and a 375 hp factory rating. The 2021+ 3.5L Ecoboost is putting down ~390 wheel with a 400 hp stock rating. I would have thought the Tundra would have fallen somewhere in between the two.

It could be difference in the Dyno or day, but 70 whp is not a small amount. Thats 20%.

 

Nice

@PapaRee - Where you looking into a tune for this? and or offering one

 

I think its different factors and the dyno, looking at their stock # for the 2017 Raptor (450hp/510lbft -ford stated), JB netted (370hp/426lbft).

 

The stock raptor is rated at 450 on 93. The stock F150 was rated at 375 on 87. A regular F150 can nearly match the Raptors numbers with 93 in the tank. Its worth almost 30whp.

I guess all i mean is I would expect those numbers from the Tundra on 87. I wonder if they are ultra conservative with the timing and 93 isnt adding much. 320 whp is about what the 2017-2020 3.5 Ecoboost made on 87 across multiple tuners and dynos.

 

Im just strictly talking about the numbers JB nets with their dyno relative to what the manufactures state, both ford and toyota seems to show up quite a bit lower on JB's dyno relative to what they say on paper. Oddly, JB got higher numbers on the 2.7L f150 they dyno'd compared to what ford states.

Looking at the datalog graph, toyota went fairly efficient on the AFR and relatively low with ignition timing (albeit the ignition values are super relative, just going off of my experience with VW tuning)

 

Right, I am saying the same thing. A 450 hp Raptor(rated on 93 octane) makes 370 whp(on the JB dyno). This is a typical number across the board for most tuners on different dynos. An F150 with 375hp(rated on 87) makes about 320 whp on 87 and about 350 on 93. I would have expected a 389hp Tundra on 87 to make 320-330 hp and 350-360 on 93. I kinda wonder if the Tundra would make the same 321 hp on 87 too, and they just arnt letting it take advantage of the 93.

The Tundra numbers don't seem far off for 87 octane. Its the fact that its on 93 and making those numbers that is weird to me.

 

I don’t really now how they could do a dyno pull when WOT makes the transmission downshift. Probably can’t even do a 7th gear pull due to the speed limiter on most trucks being set to 110 mph.

 

Looks like it ran out of turbo. That’s disappointing

 

What wheels are those

 

why ? bigger turbos that allow for more top end would compromise low end, tundra doesn't need crazy top end power to redline. And advanced timing can pick up a bit where the boost runs out in the top end as well.

 

Toyota probably tuned it for 87 octane with no provision for making extra power given a higher fuel grade. They reserve the fancy program for Lexus to differentiate the product line.

 

ah I see what you’re saying, and yeah like the other guy said, the baseline timing map Toyota has on it is probably designed for 87 with a certain degree of flexibility to adapt to other octanes but I highly doubt there’s another map on it designed for premium.

 

I agree that could be likely... and changing spark and fuel maps as well as upping boost is where the tuning potential... and risk... comes in.

 

I assumed boost dropped due to turbo size. What do you mean by not NEEDED?

 

looking at the wastegate duty cycle from JB it does seem like the turbos running out of breath in the top end due to size but that’s done to focus response and torque in the low end.

I don’t think a torque and hp curve that pulls right to redline is needed for a truck, how often are you going to use that power vs the compromises it’ll bring to low end power and overall efficiency?

 

I am waiting for it to be supported in VFtuner. As soon as it is, I will start working on it.
I was ready to buy a truck, but told my dealership (buddy is the sales Manager) that I was waiting on software support.
I will probably end up with a Pro since they will be out in a few months.
Hopefully we will get 2022 Tundra tune support soon and I can get started.

 

Meh. You should be able to copy the stock LX600 tune for a 409hp output no?

 

So how much performance do you think Toyota left on the table with the Gen 3?

 

As the new standard offering for tundra’s, sequoias and land cruisers, I’m sure there’s plenty.

 

Is 93 octane presumed to give better performance? What octane does Toyota recommend for the new hybrid?

 

You need the higher octane for higher boost to combat predetonation. Toyota doesn't recommend a specific octane other than higher than 87, but does recommend top tier fuel

 

Someone needs to measure the compressor on the turbos. That's really what it's gunna come down too.

Ford started a 35.5mm, then went to 36.7 mm, then 39.3mm and then 40.8mm. As a result the Ecoboost has gone from being able to make 450 crank hp in 2011-2012 to 600+ crank hp in 2018+ on the stock turbos.
