2016 OVTune Tacoma 3.5L Manual Transmission / Engine ECU Reflash

Can any one explain why Toyota would not have tuned this motor this way from the factory? If this gains HP, gains MPG, gains driveability, and does not harm the longevity of the motor it seems Toyota would have done this already. Don't flame me, this is a serious question.

 

They did...in other chassis. They detuned it in the tacoma

 

The main reason is so next model year they can say look 10 hp increase over the previous model year. Wooo hoooo buy the new one more power...lol

 

But why? I guess that's what I'm wondering. I can see detuning the power for future upgrades but not the mileage with CAFE standards being the main reason they added Atkinson cycle in the first place. It just seems strange.

 

Tacoma specs: 278 hp @ 6000 rpm/265 lb.-ft. @ 4600 rpm 87 octane

Camry specs: 301 horsepower at 6,600 rpm and 267 lb.-ft. of torque at 4,700 rpm 87 octane.

This is what I want my tune to do with the same throttle response as the other models.

 

I don’t see the appeal. It’s a few more HP but it’s at 6k rpm. I’ve only had my truck up that high a handful of times. You are never going to notice it.

 

An extra 25hp on 87 octane isn't appealing? On 87 octane we currently are get zero power gain on 87. Also a better throttle response isn't appealing?

 

To leave room for improvement right as the ranger comes out. Or to gradually improve to satisfy regulations over time. That's my guess.

 

25 HP at 6-6600 RPM does nothing on this truck. Like I said before, I'm never up that high in the RPM band. Maybe you are but I'd wager thats not the norm.

I was never after power gains. I've looked for improvements to drivability from day 1. The way this truck performed stock <2500 RPM was pretty pathetic. In its current tuned state, its a completely different vehicle from the one I drove off the lot. I don't know that I've ever felt the truck NEEDED more power. I'll take it if it comes, but there were much more immediate needs to be addressed than adding a couple HP.

I have zero issue with the throttle response on 1.04A.

 

The Tacoma doesn't even rev up to 6,600 RPM. What's the Camry's hp at 6,000 RPM? I'd rather have more low to mid-range power than top end in a truck.

 

Yes 25hp at 6600rpm but that's the peak hp. Let's say you would see 10-15hp at 4,000 rpm. Also a quicker throttle response would make shifting even more predictable. You have to admit it would be interesting to see how such a tune would work on a Tacoma.

 

I’ll be honest, I don’t really care that much about the numbers. If the truck is further improved in the low end I’m all for it but anything over 3500 rpm is rarely going to be seen. We’ve already seen significant gains in the low end and elimination of dead spots. I’m sure that correlates to some number but I don’t need to know what that is or see a graph comparing it to stock.

I’ve got no issue with the throttle response. The stock throttle response was trash compared to what it is now.

Now this truck with a turbo or super charger, you have my attention. That’s going to net much more significant gains for those looking for power. The tune has always been about drivability improvements over performance. It’s a matter of time until we get to the performance phase of what can be done with this truck.

 

Whiners over in that godforsaken alpha thread need to get over themselves and rethink the things they're saying about Mat

 

You were correct. I've only had it 2 days but I'm loving it! Major improvement over stock.

 

I think the whining gets worse every time I go over there.

The funny thing is, they could get it instantly and they’d still complain they can’t tune their truck because they can’t read the directions lol

 

Would somebody explain the difference between OVTune and ShiftSense Pro, please.

 

SSP changes shift points for the AT guys, and only the AT to my knowledge. The tune does that (if you have an AT) and more, such as application of power, power increase with the higher octane tune, modifies throttle response, aleviates frankly dangerous behavior of the stock tune and bogging, etc, the list really does go on

 

TLDR - SSP is a bandaid. OVT actually fixes the problem and then some

 

Thanks to Shellshock and mZiggy.

I'm most interested in the increase in power. Others have talked about this at higher rpm, but between 2000 and 3000 rpm (which is where I'm usually at with normal driving and SSP), is there any significant increase in horsepower (responsiveness)? In other words, will I feel the difference?

 

Yes you will (*edit: you'll notice the difference in drivability, to include the application of power and even addition of some, but those changes are big ones and while they may not seem super impressive on paper, they are excellent in reality)

A lot of people focus on peak numbers, and that is a mistake where this tune and truck is concerned. The number of people driving their truck at redline is a very small number, and kind of pointless too. This tune focuses on the lower end and mid range, which is much more appropriate
