VF Tuner ECU/TCU Tuning for the GX550

[xonn]

with our tunes you are likely to see a good bump in mpg. Almost everyone is reporting better mpg, and the bigger turbos are actually a bit more efficient than the stock ones, so that is also going to help with MPG.

These turbos are not just some "bolt-on" bigger turbos. They are built in toyotas factory directly, consulting with the engineers who designed this engine.
The design is made to maximize power on stock engine without any additional risk and without increasing turbo lag.

Install cost for us (at a toyota dealer) was about $5k, but it included other things, not just turbo swapping.
I'd budget $3500-4500 for install cost.

Is a tune also included with the turbos? I'm imagining the current tune I'm running won't adapt to the increased airflow.

I saw on youtube, your partnering with magnuson, what’s better, the supercharger or bigger turbos, or both?

Looking forward to the new tune with the updated shifting logic. Is it possible to do AGM battery charging in these trucks ?

yes it is possible to tune the charging system to output more voltage

Interesting, I would have thought bigger turbos mean more air = more fuel for the same level of throttle. Although maybe for normal driving you'd be using less throttle/boost. Woof on the install cost, I figured it wouldn't be great, but that's up past what a full turbo/SC kit usually runs to install. I'll have to reach out about the discount once my tune kit comes in.

we have emailed that shop and have not heard back. so from this point we are making direct connectors for the ECU for these vehicles.

Thank you. Do you have an ETA for the connectors that'll connect directly to the ECU?

I should have a realistic delivery date this week. We ordered a lot so the manufacture is assembling them.

Also, we have received several inquiries on the turbos. This GX550 delay discount is available until we no longer have shipping delays on kits.

Well I guess when its possible, i would like to get an AGM battery program and tune

 

[Bluegill]

I'd be interested in the AGM tune as I am already running an Optima yellow - top AGM battery.

 

[VF Tuner]

Our connectors have arrived, CAN connects are being built right now.


Also, no more laptops soon
read/write/tune/log and more.

Will iPhones work or is it only android?

 

[VF Tuner]

of course iphone too. I have an iphone lol

 

[rocksallday]

of course iphone too. I have an iphone lol

as soon as that works I'll put in an order.

 

[monsieurvo]

If the tune is done via this new connector to the ECU, will it be traceable? Presumably yes?

Let's gooo! I gotta be close to front of the list hopefully. lol. That'll be sweet with the phone connection, would that make it a quick process to switch between tunes on the fly? I don't have 93 readily available at a convenient location anyway, but do have some stations in the area and would love to at least check the difference between the 91 and 93 tune on the fly if it's a noticeable difference.

I’m selling my GX…is the cable useful for anyone if I sell it or is it locked to a VIN?

 

[munkeeboi]

The cable itself will be helpful, but the buyer will need their own VF tuner license

 

[xonn]

@VF Tuner update on the new tune. As I drive the GX more, fuel economy and estimated range keep moving up. On a recent road trip that combined back road and highway driving up and down hills in Georgia and TN, this is what I got for MPG and estimated range.

Pretty cool.

 

[xonn]

In case anyone asks, this is with cruise control set to 77 mph. So wasn't just creeping along.

 

[monsieurvo]

@VF Tuner can you please ship to me the latest ecu connector as the substitute for the CAN connector which didn't work for Aussie cars? Sent you an email.
