Eco Block from crawford performance

On the 1GR-FE you're in open loop way more often you think. Just take a look at the attached file and you'll see.

After start up depending on temp you can be in open loop for 40 sec. It's a kind of electronic choke.

 

You can't have both more power and better fuel economy by tinkering a MAF. When it's in open loop the O2 sensors are not in the picture. The emission testing does not include WOT so they can dump fuel to give you the power, it takes fuel to make power. The vehicles are tuned for emission. drivability and economy not WOT performance it's only there for short term. The O2 sensors will alter the mix to achieve the best possible stoic mix for peak efficiency not peak power.

 

So if you reduce fuel consumption by leaning out the tune, which gives you more power, how are you not affecting both?

 

Our EB will not work with a tune or cold air intake as both of these make the same changes to the ECU.

The 13 might use our Q3 which is in production, can you take a photo of the MAF sensor so I can confirm?

Thanks

 

The 02 sensor must get up to temp before the ECU will / can go into closed loop, before that time the ECU will have no idea what the AFR is so it runs off the fuel map.

The money back guarantee is good for as long as we are in business so you are good on that.

 

What type of dyno have you used to gather this data, or are you just guessing?

These dyno runs and accompanying graph I did clearly show a rather large power increase, and if you look at the AFR data you will see that the the higher power was made with less fuel.

 

Are these good enough?
Thanks, Diego

 

I have a 13' and Installed the Q1 with no issues.

 

Perfect, that style is Q1

 

Ordered! Thanks for your help!

 

So based on your comments and most of the negative comments we've read here, the MAF controller from URD is shit! Cause it's exactly what it did, tinkering the MAF readings.

So based on your comments, the most fuel youre dumping better is the power! So for you having an AFR of 10 or less at WOT is OK and is producing a lot of power! Producing an AFR of 10 at WOT is not dumping fuel, It's wasting fuel.

The flash in the Toyota ECM is producing way to rich AFR at WOT and it's why a lot of guys here using a MAF controller from URD to maintain an AFR of 11-11.8 with boosted application. Same power, even better with less dumped fuel.

 

You are welcome, thank you

 

Good to hear

 

I'm not sure why everyone is getting so argumentative over this mod. The principle makes sense but who knows EXACTLY what this mod will do for our Tacoma. Just like initial observations on CAI's, the URD MAF, and other past mods this modification has not yet been independently been dyno tested. The company is reputable and I have no doubt that this modification does something. However, I'm skeptical as everyone always should be that this mod will give dramatic enough increases to translate into a real world feeling. Until I see dyno results on the V6 or a dozen-ish reviews by reputable members I'll reserve my judgement.

 

After reading through all of the various posts there seems to be quite the transformation in attitudes about this product. Quirt has done an outstanding job of exhibiting patience and providing information and free dynos in order to prove his product.
That being said, I wasnt clear about whether this product will work on 1) A 2015 supercharged motor 2) with a CAI?
I thought there was a post about the CAI doing the same thing as the Crawford product?
Sorry for my confusion...it just gets worse as I get older

 

I still am not convinced, I ordered one to see if I can tell the difference. I have a pretty good average on my mpgs and we'll see if it decreases or increases and the seat of the pants feel.

I just don't see it happening with the twin O2 sensors actually controlling fuel mix.

 

Well said.
If you are looking for a large increase then this is not for you. Our EB is a simple part that gives a small increase which others charge upwards of $200 for.

If you do not have a good "butt dyno" then the only way to quantify the power increase is with a dyno graph. The mileage increase is much easier though but it should be spread over 10 fill ups to give you a realistic average.

We will get a dyno graph for you soon, hang tight!

 

I think the argument being made by quirt and a few others is that we are in open loop for far longer than we think we are. It could be true, but for most people like me the engine will still be in closed loop for the majority of time so gains should be marginal. Who knows though, like I said I'm waiting for more members to report back numbers and for someone to stick this thing on a dyno with a Tacoma.

 

I already have a CAI (Volant with Donaldson PowerCore) and I'm supercharged so this product isn't for me anyways at this point even if it works. I'm always curious though about new products that could evolve into something that would give me a little extra for very little cost .

 

sooo... with all these posts.. I lost track..

but.. as CleanupBoss asked.. will these work with the TRD blower and/or CAI..

Will it depend on the intake tube Diameter for the latter? I thought I read that in here at some point.
