Anyone tune their 4R? - Toyota 4Runner Forum

Monomaniac · 01-24-2014, 07:33 PM

Real curious to see if anyone has messed with the 4runner's tune. I know that the 5th gen runner's power has been de-tuned to give better fuel economy. Like many others I wish I had the option to get a v8 in my trail but no such luck. I had a 2006 Xterra that would run circles around my runner but it sucked down gas like nobody's business. With that being said, anyone find a way to get better throttle response or unleash some hidden power? I saw that bully dog offers a plug and play tuner that might have some potential.

Sorry. It has not been detuned just "optimized" for efficiency. Unless you have a new ECM then you are not going to change things. The Bully Dog thing was discussed several months ago and a few here were supposed to get them to try. I don't think that went anywhere.If I need to change my shift points I just use sport mode instead of spending a grand to do it. You have put on quite a bit of weight judging by your signature including unsprung weight. You might want to look at regearing as some here have done. That is your best bet.

Bully Dog - Gas and Diesel Performance

We had some great information in this thread

Engine Management Software...hmmmm

It's an interesting product. Looks like the max you can get out of it is "up to" 25hp and 30 ft\lb of torque. I would like to know how close it comes to those numbers in the real world because $1k is a lot of money. Also consider that the engine has not been tested with one of these programs running, and it would be hard to know the long term ramifications of constant use.

WillK · 01-24-2014, 08:06 PM

I'm sure those numbers are high, but in the aftermarket world, $1,000 for that kind of power (25/30) is cheap.
As for wear and tear on the engine, it would be minimum, if any.

That's what I was thinking but couldn't put it in words as far as "de-tuning" much better put as "optimized" . I know it was a long shot with the bully dog and $1000 is def lots of money but I was just looking into all options. So nobody actually went through with the bully dog to report any results? I don't think I added that much weight, the plow doesn't stay on. Only the truck mount stays on and only during the snow season and it's only about 50 lbs. I have to do some snooping around about the gearing though. How will the gearing affect fuel economy, going with mild gearing, as it is my daily driver. Btw, I love the limitless amount of knowledge on this forum.

I'm sure the Xterra felt faster, but a 5th gen would show that Xterra it's taillights all the way through the quarter mile.

2006 Xterra: 0-60 7.4 sec, qtr mile 15.8 sec
2012 4Runner: 0-60 7.2 sec, qtr mile 15.5 sec

They are faster than they have a right to be given their weight. You just have to push them a bit harder.

I think those numbers for the Runner are estimated.
One magazine tested it in a head-to-hear competition and the Runner ran much higher than a 15.5.

I'd put my money the Xterra all day.

Haha, the company I work for has me driving around in a 2006 Frontier. It feels super powerful as the throttle is setup the exact opposite of the 4runner. It's the biggest piece of crap when it occasionally snows as your big toe on the throttle spikes the revs to 3000rpm. When you push the throttle 5% it opens the throttle body 30%, or so,it seems.

You would lose your money.

Winner, winner chicken dinner!

Somebody on here was talking about an aftermarket controller for the 4Runner that made it do the same thing. I prefer to use my foot.

Not hardly...

Car and Driver.

The 4.0-liter V-6 with its five-speed automatic (as before, no manual is offered) keeps pace with traffic easily enough, although at 7.8 seconds to 60 mph, it proved slower by 0.6 second than the last 4Runner we tested in April 2005.

C/D TEST RESULTS:
Zero to 60 mph: 7.8 sec
Zero to 100 mph: 22.0 sec
Standing ¼-mile: 16.1 sec @ 88 mph
Top speed (governor limited): 105 mph
Braking, 70-0 mph: 201 ft
Roadholding, 300-ft-dia skidpad: 0.73 g

I see - the best case scenario for the Nissan is representative, but the only the worst time is representative for the 4runner.

Don't be a putz.

Learn a little about non-linear throttle response and how that's used on vehicles sold in this country to make them feel more powerful. Then spend a little more time learning why it's a bad idea on a serious off road vehicle.

So what did C/D test the Nissan at? Honestly, realistically, I would expect the lighter, simpler, XTerra to do 0-60 quicker. I'll bet $1,000,000,000,000.00 a stock XTerra is faster 0-60 than my 4Runner.
