VR Tuned ECU Flash Tune Toyota 4Runner Dual VVT-I 270HP

This looks pretty interesting! Anyone have this yet? I did the similar tune to my IS350 and it seems to be a lot better performance wise and mpg wise....

[enkrypt3d]

No one?

I’ve been looking at this since they are local to me... ‘course I need to get a new t4r first. Hopefully someone here or the other forum has some experience.

Run a search. I remember seeing a 2-3 page thread a while back.

Interesting, if not local u need to buy a genius handheld to program, thats another $250. So its $750 plus other optionables.
I've had other handhelds for other vehicles in past and was happy with results but I have limits.

[Area52]

Yeah fairly steep price for somewhat moderate gains per the video. I’m waiting to hear a real world review.

Im holding my breath for the 6 Gen. Maybe then we can get some aftermarket support.

So I have the Vivid Racing tune on my 19 SR5. We recently went on a 1200 mile trip. Part of the trip is thru the hills. Drive ability was great. I didn't feel like I had to slam the peddle to get up to speed. At the times I needed to speed up or pass I gave it some more and it picked up speed very well. I can compare this to my Dodge Charger Hellcat ... yes no comparison but difference from stock is much better. I would recommend this to anyone seeking improved proformance or better drivability.

When you’re on cruise through a mild hilly area does the trans still shift around or is there enough power with the tune to stop that?

Which options did u choose? I'd probably do stage 1 + ECO... how has your MPG changed if at all?

And yes I'd love it if the trans would stop trying to shift gears 30 times a second and keep me in the power band a bit more...

The transmission wasn't shifting a lot , but I didn't have the cruise on like I normally do. When more power was needed it didn't take much effort on the pedal.

I used the handheld.

I got the stage 1 only.

Hey Folks,

I have the stage 1 tune from Vivid. For context, I drive a stock 16' Trail and run 91 octane both pre and post tune.

The install process is straightforward, provided you have basic desktop computer experience. A link to step by step instruction is provided. Some of the software steps/menus are slightly different than what is illustrated in the directions, but fairly intuitive. General steps:

1. Download MyGenius software to Windows laptop
2. Connect MyGenius handheld flash device to laptop
3. Prompt the MyGenius Windows software to find and install any updates for itself, as well as the firmware on the handheld flash device
4. Connect handheld flash device to 4R and download stock ECU file to handheld
5. Connect handheld to computer, and download stock tune file via the MyGenius software
6. Email stock tune to Vivid
7. Vivid emails tuned file back
8. Use MyGenius software to load tuned file onto handheld
9. Connect handheld to 4R and write tuned file to ECU

Now the part you actually care about haha, PERFORMANCE... Primary differences I noticed:

1. Increased throttle pedal sensitivity, call it 20%. Response is not completely linear now, but more so.
2. Significantly less hesitation to downshift when medium to heavy throttle is applied.
3. Ability to hold 5th or 4th gear on mild to moderate grades at highway speed without gear hunting. Before, it would downshift to 4th much sooner and inevitably also to 3rd.
4. Truck feels "lighter". Obviously that's ambiguous and subjective, but acceleration seems a little faster and smoother than before, again without necessitating as much downshifting. Accelerating to merge with highway traffic on an uphill on-ramp is noticeably easier.
5. Roughly 0.5 mpg improvement if I drive conservatively.
6. No change in engine noise or idle quality.

The truck is still not a sports car. At no point will you feel pushed back into your seat. The additional performance almost sneaks up on you. The truck just gets up and goes more quickly, without the "drama" of multiple downshifts and sudden high RPMs.

In my opinion, the more lackluster reviews on this product are caused by 2 things:

1. Much heavier trucks. The improvement will obviously be less noticeable on a vehicle with 500+ pounds of accessories bolted on. Same goes for taller / more aggressive tires which reduce effective gearing and add more rolling resistance.
2. Folks not using premium gas. The bulk of the power gain comes from more aggressive ignition timing. The higher octane gas you use, the more aggressive the timing can be without causing detonation.

Hope this is helpful. If you're looking to make the driving experience smoother and more confident, this is a worthwhile mod.
