Nice ECU Tune found for the 200 5.7 (1 Viewer)

[TLC Dan]

Hello Mudmates,
I recently met up with a tech from Big Turtle Tuning. He installed a new tune for my 2011 LX570. It adds 37ft lbs of torque and 20HP, mostly in the 1500-4000rpm range. Part of the upgrade is tuning the trans to hold gears longer (more throttle applied) before downshifting. The improvement is noticeable. It feels like the rig lost 600 lbs at least. It just goes better with less pushing of the go pedal. It feels better than when you switch to ECT power mode. It just pulls the grades better and feels lighter. MPG's are likely better as you just don't push the gas pedal as much. I can't quantify the gains as i just added heavier KO3's 2 days after the tune was installed.

The tech noticed that my LX didn't have the latest Lexus update and installed it before he added the tune. He said if it was ever in for service (not likely) and they added the update it would override the new tune. He assured me that if this somehow happened, he/they would reinstall the tune for free.

Here is some info on the company. Log into Facebook - https://www.facebook.com/bigturtletuning

Let me know if you have any questions or contact Isaac at 208-661-1389 for more detailed info.

So it's $600 for the base tune and $700 for a custom tune. What's the difference between the two? It isn't mentioned in their website

From what i understand, their is different prices for different vehicles. I payed less than both of those prices. I have asked Isaac to chime in on this and hope to hear from him soon. He has a day job as a realtor and not as available is some of us.

Best regards

I just had a PM session on Facebook. The tune is $600. The custom tune is only if you have an aftermarket intake and that's $700. They'll update the ECU if necessary before the tune. I think besides any power increase if any, what is mostly felt is the changes to the transmission logic. This might be beneficial to my LX since I'm running 35s without regear and fairly heavy.

Is this tune available to install at home by consumer?
Oh, nvm, just found their website. Looks like the newer LXs (16+) aren't listed on their site though.

You should definitely feel a power increase. Kinda like putting it on a diet.

If they're tuning with the VF Tuner, the 16+ is now supported, even if it's not explicitly listed on their site.

Good morning! The base tune uses our VF tuning platform and for those without hot air intakes it's perfect, but those who have those aftermarket intakes will need custom MAF scaling to accommodate which requires us to use the HP tuners platform and that is where the custom will come into play.

16+'s are supported, we need to make some updates to our website which we are doing but honestly, we have our focus currently on building and refining the tuning for the 23+ Tundra/sequoia and 24+ Tacoma/Gx so those clerical updates have been on the back burner. The best way to know what vehicles are supported is to reach out to your local OTT tuner and ask. If yours isn't supported follow their page as we all post when new vehicles are supported well before any updates are made to reflect those changes on our website.

Thanks @BigTurtleTuning for chiming in. Just fyi this is a forum for 200 series land cruiser/lx 570, which have the 5.7. The lx 570 version is tuned slightly different to eke out some minuscule hp gain and requires premium fuel.

Would love to hear from some other forum members who have more familiarity with tunes on their thoughts around the long term risk/reward of doing a tune like this.

I dont think the LX570 is actually tuned different. Ive looked at my tune and it appears to be exactly the same as tundra and LC tunes. It just that they publish the HP and torque numbers on premium fuel. The PCM of all 5.7L vehicles(and any other modern Toyota) have the ability to advance or retard timing on the fly based on the fuel octane via Knock Feedback and Knock Correction Learn Value(KCLV)

Premium fuel is only required to make the advertised power/torque.

I've reached out to the most local shop in the toyotatuningnetwork about tuning my '17 and '18 LC200s. Would be nice to do one and keep one stock for back to back comparisons but will likely do both at same time just for convenience.
Got some additional info, added below

Info from my contact concerning tuning my totally stock 200's:
Yes sir, cost is $600 which includes any necessary TSB updates for the ECU, VIN registration to the tuning software for nationwide support within our network, as well as if you need a simple adjustment down the line for throttle sensitivity as an example.

The benefits include improved throttle response catered to your preference/setup, smoother and refined shifting, reduces gear hunting, increased low and mid-range torque, and more linear/consistent power delivery overall.Additionally if you have the Tow package, you'll have a separate calibration tuned to your Tow/Haul button for a more sensitive throttle than your daily driving along with tow oriented shift points.

I asked if this means that I can remove my Throttle Commander and the reply was:
Correct, we have different options for throttle based on the weight of the vehicle as well as your personal preference. I’m also not really a fan of those throttle modulators personally because they are working against the calibration on the ECU.

Look forward to having this done in early fall and will report back with a first-hand report.

I'm taking my 2017 LX570 (100% stock) to do a tune this weekend. Will report back with the experience and results.

It adds 37ft lbs of torque and 20HP, mostly in the 1500-4000rpm range. Part of the upgrade is tuning the trans to hold gears longer (more throttle applied) before downshifting

Can you explain a little more about this last part? Personally, I think it takes too much throttle for the LC to downshift. I feel like it's either 0 or 100% throttle.

This was the main reason for me adding a pedal commander. The pro of better throttle response, especially while towing outweighed the con of having some device in between the pedal and Cruiser computer. I’d prefer to ditch the pedal commander, and may do so, depending on how the reports of the tune go. I’m suspicious of the tune as well, it’s probably due to my age…growing up, to get gains it was always done mechanically as most of my experience was with carbureted cars.

I have never driven a LC but on my LX570 it didn't take a lot of push on the throttle for it to downshift especially when in "ECT Power" mode. Now, while in std mode, it takes a lot more push on the pedal for it to downshift utilizing the additional torque displayed on the Dyno graph I showed previously. The downshift while in "ECT Power" mode is about the same. This, in my opinion, is one of the best aspects of this tune. The extra power off idle is a close second.....

Artie, With our advanced age (I am 62) skepticism is rampant as we just use our experience to second guess or question changes. I was not sure of doing this tune but was assured that if I didn't like the changes my money would be refunded on the spot. I am so impressed with to new power band that I would never go back. It just goes easier and better.

I do not have any affiliation with Big Turtle tuning or Toyotatuningnetwork just loving the new feel of my LX.......

I just want to shut off secondary air injection and evap permanently without lights or limp modes.

I want stock mapping otherwise.
