Eco Block from crawford performance

After Getting 10 pages in I have to say:
Wow, so much effort into digging, sarcasm and scepticism that you would think Crawford were running for the presidency.
It's a $45 part guys, relax. Purchase it if you want to try it and if not let it go, time end effort spent better elsewhere other than debating a part most of you do not own.
No I don't work for Crawford, no I did not make this account just to jump into this conversation and no I'm not running for the presidency.

 

This does not work. It just doesn't. If there are believers out there pm me and you can have mine for $20.

 

Sold. Pm inbound.

 

Dam it I had to listen to my wife's day at work and missed out on a$20 eco block.

 

I don't know... my gas mileage went back up 2mpg after putting it back on. So I am perfectly content with it.

 

It does not work for YOU, to be specific. It has worked for many others, including myself. Thanks for trying it out and I am sorry it did not provide the results that other Tacoma owners have experienced.

 

Now that there is more reason to believe this works, was the question of reliability ever addressed? There's got to be a trade off for this, right? A reason Toyota didn't tune this way in the first place?

 

anyone tried the eco block with a URD True Cold Air Intake yet ?

 

What's your concerns about reliability? I don't think that it can be worst then most of mods Tacoma owners do on their truck like super charger, CAI, exhaust, headers, lift, etc..

 

I haven't seen anyone try this with the URD. Also note that if you have the MAF Cali installed. Personally, I would not run the MAF Cali with a properly tuned map and this spacer. Risk of running too lean is too great.

 

There is absolutly no reason to run a MAF cali with the ecoblock. The purpose of the ecoblock is to mechanicly emulate what your doing with a MAF calibrator to correct AFR at WOT. You are way better serve by a MAF cali (well tuned).

 

My concerns about reliability are that there must be a reason Toyota didn't choose to do this in the first place. Notice, Toyota trucks are generally more reliable than others but a little less efficient. It's also known that Tacomas run very rich, and I think there is a correlation between the two. Not that I know everything about how the engine was designed, nor do I know everything about this spacer, (which is why I ask the question) but it seems to me that the premise of this gained MPG by simply moving a piece an inch higher in the system, is that we are eating into something. If I had to guess what it was I'd say it's making the engine not run so rich so to preserve some gas. I'm not saying this product is bad for the engine in any way, just asking "what gives" and explaining my curiosity.

As for a S/C, I think that's a little bit of apples to oranges. A supercharged 1gr might not last as long as a stock 1gr with the eco-block (or it may outlast it, who knows?) but the eco-block doesn't cost 5K and give 68 HP. Yes I agree there are worse things you could probably do to the truck (even running oversized tires can be considered detrimental)

 

MAF calibrator is for open loop to prevent an excessively rich mixture, not the same concept as the ecoblock to be perfectly honest.

The Ecoblock won't make open throttle response any better.

 

Not totally correct the Cali can be used to "fix" the MAF readings in closed loop, similar to the mechanical method of the block. This is how the Cali can fix the MAF readings for an improperly matched intake tube, like in the Volant.

 

Toyota, as all manufacturers, need to design to a set of specs that will work for the vast majority and will be safe over a wide range of conditions. As far as AF then, richer is safer, as too rich causes problems, but not catastrophic problems. Too lean can cause holed pistons and other internal nasty damage.

 

Hmm, really? Not throwing anything out but I was always told the MAF Calibrator didn't do anything for tuning once the engine was in closed loop. All the MAF Calibrator is "fixing" on those Volant intakes is the resistance value coming from the MAF to get the engine to not throw a code. The MAF calibrator is not for tuning the closed loop part of the engine cycle, at least not that I know of.

 

No MAF Cali yet, maybe in the future but for now truck runs amazingly with jus the URD TCAI !!!

But if there is anyway to get a few extra MPG out of a 4.0L with this on the cold air intake I would love to add it !

 

"Induced MAF sensor error" is the term to research up on. While in closed loop the AF sensor is more important then the MAF, but the MAF is still used to set the injector pulse, with the AF sensor used as the process end check that the AF ratio stays optimum. It's definitely borderline to call that tuning, as with the Volant, the MAF readings are off due to the intake tube cross section delta with stock. But end of the day, the Cali helps set the MAF reading such that short/long term fuel trims don't get all wacked out. Same concept for the block, modify the MAF reading to subtract some injector pulse.

 

^+1, your right. Normaly you will use it to correct your LTFT and have close to zero and then set your AFR in open loop. But like you said, doing this you can correct for important LTFT that generate error codes (correct me if i'm wroong but i think a code is produce when total trim is larger then +-15%).

And yep even with a MAF, in closed loop an AFR of 14.7 will be maintain by the ECU.

 

Sorry but to be honest the ecoblock is reducing the MAF reading by moving the position of the MAF sensor in the flow patern and the result is a reduced reading and then a leaner mixture at WOT. I thinks it's clear that mechanical vs electronic adjustment are not exactly the same concept it's why i was talking about emulation. Carburator and FI system are not exactly the same concept but they have the same purpose.
