Anyone tune their 4R?

[TonyJ124]

I wouldn't be scared to try a tune on my 4runner, but the fact that almost nobody has done it keeps me from investigating it.

To add to the debate, I had a 2010 Xterra with a 6-speed shifter, and I'm sure the xterra was faster, but I'd bet that's just because I could wring it out it every gear. I'd say the throttle response of the Nissan was faster/crisper, but I have no data to back that up. Either way, I find I drive the 4runner MUCH less aggressively, mostly because it just doesn't respond to it (obv not built for performance) and just feels a lot more like a heavier truck. Probably a good thing, since my MPGs stay in the 18mpg range now that I drive like a grampa. I'd still entertain a tune if it were tried and true... Sometimes I do miss the torque I had in my tuned TDIs...

"Sport mode" ? Do I have that on my 2010 Trail

Do you have the ability to move your shifter to the left from Drive and manually shift it up or down? If so, you have Sport mode.

OOh.. I see... :driving:

Thanks

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.

In motor sports excess weight is losing. The general rule they use is for every extra 7 pounds you are giving up 1 usable horsepower. It's why most racing organizations mandate a minimum weight for their cars. If they didn't the mechanics would be stripping the cars down to the point of being unsafe for the drivers, or using exotic materials that would drive the less well financed teams out of the sport.

When I replaced the tires on my Tundra last year I went from a strictly street sport tread to a more off road capable tread pattern in exactly the same size. Just the additional weight of the extra rubber for the lugs on the new tires immediately reduced my MPG by 1.5 from what I had been getting for 2 years. The nature of my job requires me to take long drives to and from job sites (400 miles or more). My mileage can vary by as much as 2 mpg just based on how conservatively I drive over those trips. If I just engage the cruise and don't care about it downshifting on hills my mileage suffers. If I drive carefully, disengage the cruise as I approach a hill and give up a couple MPH while holding my foot steady, it doesn't downshift, and my mileage is better.

As for gearing, a taller (smaller number gear) will generally get you better mileage up to a point. A shorter gear (higher number) better acceleration and throttle response. But it is a trade off based on your tire size, driving requirements, load ability, etc.

Wow! You got me going on a subject that is near and dear to my heart. Sorry about the long winded response. :wow2:

No need to apologize, I think we all are trying to learn something new here and there and also share some knowledge. Otherwise, none of us would be typing away on here.
