Eco Block from crawford performance

Is the Q1 good for the 2014 Tacoma? I couldn't find it on the list

 

The code eco-q1-feb was supposed to be good for all of Feb

I can get a new code tomorrow and or refund the difference, sorry guys.

 

Going back to the theory I learned in school, there should be an optimal AFR for engine efficiency which I imagine would effect both mpg and braapp. I know that running too lean can cause damage, so manufacturers probably set things up to run slightly rich for a safety factor. There's always a slight variation in manufactured parts and sensors, so this would prevent some of the vehicles from running too lean and having issues. By moving the sensor they're tricking your engine into running a little leaner, which would put most engines closer to the optimal AFR. Due to variance mentioned above, some engines may go too lean and be further from optimal which is what toyota was trying to avoid. Take this with a grain of salt as I'm no tuning expert.

Edit: You aren't changing the airflow per se. You're changing the ECUs interpretation of airflow to hopefully gain efficiency.

 

Okay. Thanks for going into detail, now my only concern is the "engine wear"
If this can do what it claims to do without turning my truck into a hunk of junk when I go to sell it I am in.

 

Sounds good.

 

We are not changing the air flow Devin, it is staying exactly as it was before the installation of our Eco Block.

Air and power do go hand in hand, if you can increase the amount of air going into a motor then you can inject more fuel with it to make a larger explosion. Explosion = Power.

if you reduce the amount of air going into a motor then you also have to reduce the amount of fuel which will make a smaller explosion.

What we are doing is changing the Air fuel ratio by injecting less fuel with the same amount of air. The new air fuel ratio is more explosive than the stock one so we get a larger explosion while using less fuel. Larger explosion = more power. Less fuel = increased mileage.

Simply put, we are increasing the efficiency of the combustion process a little bit which is giving us the small increases in power and fuel mileage.

 

Theoretically you would have a small chance of increasing engine wear. How small depends on a number of things that only a manufacturing engineer at Toyota would have access to. It is probably a pretty damn small chance though.

 

More power means more wear on the entire drive train. But you need to put it into perspective by doing the math to see the percentage of increased power. Mostly we have seen a 5% increase in power....

 

Wouldn't the wear and tear question be more related to driving style and maintenance?
Rather than direct impact from the part?
Is the concern that because of more go feel, more tendency to aggressive driving style.
In my opinion, proper maintenance has always played a larger role than driving style.
Enthusiasts, although more aggressive than grandma, tend to be more keen on maintenance. Pops always liked to blow out the carbon.

 

That's a good point Quirt. I wasn't thinking about the extra stress from the added power. I was just thinking about the AFR. The extra power should only matter while you're using it though... so 1% of your time at WOT with 5% more power... I'd think that's going to be a negligible impact on reliability.

Going back to the safety factor and AFR stuff... if you put this on your truck and it makes Moar powah then I think you'd be fine. You're taking advantage of better efficiency. If it hurts mpg and powah, then you have one of the 0.01% (or whatever the number is) of engines that Toyotas safety factor was trying to protect and you should probably take it off.

Again just unbiased thoughts from a guy with some basic mechanical engineering courses under his belt. I'll repeat my "I'm no expert" disclaimer.

 

Got it! Thanks a lot Natural and Quirt. That all makes sense. +1

 

Code still works for me. Got bored and decided to order one for my 4Runner...been tracking my gas mileage for the past year on an app on my phone so I'll see how that goes. Anything over 14.5 mpg will blow my mind.

 

Just ordered my:

#2409 DATE: February 27, 2015 3:12 am TOTAL: $ 49.45

 

Both of mine shipped yesterday... woot woot.

 

Been seriously looking at the XV for many reasons, but will still keep my Taco for work, towing, camping etc. I'll be ordering the Q1 today and provide feedback soon after. Thanks for your professionalism in answering the questions here with facts and experience.

 

Ordered mine this morning. Will post results asap.

 

You are welcome, if you have any other questions just ask.

 

Sounds like a good challenge, excited for results

 

Jon will be busy shipping today, thanks!

 

Are you sure???
