VOLANT INTAKE WITH RAM AIR SCOOP

I thought even the maf calibrator was capable of open and closed loop tuning

 

Custom tuning is specifically to optimize the power across the whole power band.

 

Ideally, yes. But this is a stock toyota engine, not a LS.

 

And?

 

Dat tar be a good reason y tooners don't work on them Tojo engines. Uh huh.

 

Wow I turn my back and the expert comes out....
This is the part I hate about TW someone that doesn't know what they are talking about is always an expert...

So yes you can tune a Tacoma you are just stuck with the factory settings in closed loop....
and you can cheat some negative trim in to add a little more fuel...
The problem with the intake is it is too far negative and the computer corrects back to 0 or over corrects to positive trim...
Making it harder to cheat in more fuel...

With this intake the maf sensor map need to be recalibrated but there is no way to do it, all we can only tweak the output. This is why I waited so long to get an intake because I knew it would throw off the maf calibration. But it still makes more power/pulls harder, especially at higher RPM...

I'm currently using the Unichip because it's plug and play and with the limits of the Tacoma it works good and I may have just figured out how to make an MPG map because mileage is back up so far...

The best value is the urd maf cal and I ran that for 3 years and love it but, I wanted map switching and to be able to advance the timing.

 

So is there some real dyno numbers or is this thread as worthless as it looks? Did I miss them somewhere?

 

By more power, it accelerates better and it very noticeable...
Merging in traffic, passing and over 3000 you don't need a dyno...
I just sharing my experience and another TW "expert" is trying say my experience is false. But how would you know?????

I had no idea if it would run better or not but it does with some fine tuning and you don't need a dyno to feel it...
I could do 0-60 times but it's still winter up here and I'll just spin the 33s...

It's amazing how every engine in the world is an air pump except for on TW were none of the performance mods you do can ever make any difference...
If I put nitrous on some "expert" will come on saying that doesn't do anything, if I lighten the truck 1000 pounds someone will say it won't make a difference, if I put in a LS2 crate engine someone will say they tried it and wasn't any better.........

The reason these mods don't feel like they work is because you need to add more fuel to net more performance and most people don't know how to do that...
If you lean the truck out it won't feel any better but it's getting more air so it just needs more fuel...

 

Because you have not shown at all how this added more power. "I felt more power" is bogus. It could be placebo.

I could just as easily put on an intake and say it doesn't feel any different (because it wouldnt)

 

Maf cal works in closed loop iirc

 

Look at his other thread. You think you're the first member to brashly cynical, and not proven wrong by the history which is also compiled on TW? No.

 

Yes, to a degree.

 

14.7/1 is too lean, so leaning it out any more will reduce power in closed loop... So if you just add an intake without any tuning it may not feel any better in closed loop because it's too lean...

The maf cal can bring you back to normal trim and sneak in a little extra fuel...

These piggy backs aren't the best solution but much better than nothing.....

 

Changed my mapping strategy and the truck is running better and getting better mpg.
I'm back to the 13-15 mpg range which should be OK for winter using winter gas. Should get me back over 16 in summer.

The stock intake may be better in the 2000-3000 RPM range with stock mapping.
After running up north it felt sluggish in this range but much better over 3000 rpm.

But with the stock computer it's a slow process to remap but it's getting better.
With the learning computer you have to make small changes at a time to see how the computer will react to it.
My last map feels much better in this range but with the snow storm I could only push it so hard.

This is a fun truck in the snow, with some weight in the bed and the st maxx, I was tearing around with no problem and cars are in the ditch all over the place. It feels good when all your hard work gives such an advantage over normal vehicles...

 

Intake is running great, still feels a little flat around 2500 under heavy load compared to the stock intake.
The stock intake must be tuned for the 2000-4000 rpm and makes good torque in the 2000-3000 rpm but starts to go flat and gets weak above 4000 rpm.
Above 3000 rpm this intake pulls much better than stock, doesn't run out of breath just keeps pulling to red line. I could see how an intake can add 20 hp on the top end.
But this is a truck and we need power from 2000 rpm.

Part throttle seams to run good, still tweaking the 2500 rpm range to see if it's the tuning or the intake.
I don't think this intake would be too big but we'll see...

On a street truck I would probably get the URD intake for the longer intake tube.
Plus my trans cooler is in the way......

 

20hp? Come on bro...

 

Most of them claim 15-20, I can see it, but at higher rpm where the stock intake is choking out...
We all know this engine stock doesn't pull hard over 4000 rpm, but this intake changes that.

Like I just said the stock intake feels stronger at 2500rpm but this intake is much stronger over 3000 rpm. Below 2000rpm it runs smoother but seams around the same power.
over 3000 rpm has to be over 10-20 hp to pull that much better.
But that is with proper mapping. not stock mapping.

If I get time when it warms up I may do some 0-60s back to back to see the difference.

 

Of course they claim insane gains. They want you to buy it. Hydroxy cut claims I will lose 20 lbs in a week just from taking their pill

 

I'm figuring out the mapping with the new intake and the flat spot may be almost eliminated. Didn't really notice the flat spot till I was up north in 4wheel drive and it was very noticeable, it was a lot weaker in the 2000-3000 rpm range, even my girlfriend could tell. I think I have solved that with tuning so we will find out on the next trip.

My new breather system is working better than I thought and now my air box is my oil separator, water and oil is collecting in the bottom of the air box so now I'm going to need to add a real oil separator. It is very good at sucking the moisture out of the engine, unfortunately I have to do a lot of short trips only 15min and I live in WI.
I like the breather system keeps oil out of the intake and dirt out of the breathers and enough volume to evac the engine.

After my first off road trip this is the first time I had no dirt, out side water, rocks or sand in the intake. So for now, I would have to say the ram air scoop works great. I still have to test it on the dunes but for general off roading, it works great.

 

Everyone should be looking at some type of oil separator for both breathers.
Here is how much oil Detective_Dan pulled from his oil catch can after 10K from just 1 side.
Some that oil would be collecting as residue and carbon on the valves and pistons.
