What are your thoughts on URD's AFR sensor calibrator? (http://www.urdusa.com/product_info.p..._id=1230100028) It sounds like they are trying to do the same thing that SS was doing with their ESC1, but does it work any better? or is it just he ESC1 branded with the URD logo? If it is different than the ESC1, and works as advertised, then that would fix the 14.7:1 while in part throttle/low boost situation right?

The URD AFR Sensor Calibrator is very different then the Split Second ESC1.

The URD AFR Sensor Calibrator is for the newer trucks with the new style air/fuel ratio sensor as opposed to the old style O2 sensor. The air/fuel ratio sensor is Denso's version of a wideband sensor. Much more accurate then an O2 sensor. It gives a direct indication of fuel mixture as opposed to an O2 sensor which can only report if the mix is richer or leaner then 14.7:1, but not the exact mixture.

The URD AFR Sensor Calibrator is a mappable unit that uses a true 3 dementional map table like the URD MAF Calibrator or the MAF/Timing Calibrator (FTC1).

It will allow you to alter the fuel mixture in CLOSED LOOP mode and it is very precise and repeatable in its operation. It is best used in combination with a MAF Sensor Calibrator or an additional injector system.

For the 4Runner it is compatable with 1999 Cali and all 2000+ V6 engines.

For the Tacoma, it is compatable with the 2000 Cali and all 2001+ V6 engines.

A complete application guide can be found on the URD site.

From my understanding: 2 cats= AFR (cali models)1 cat= front and rear O2 sensors (fed models).

Anyways I'll drop ship the AFR calibrator NIB to you for $200. Drop me a PM if you are interested.

The number of cats has nothing to do with what sensor O2 or AFR you have.

Your truck is a 2000 4Runner. Yours has an AFR sensor and not an O2 sensor.

Gadget,

Both sensors on my 4runner (pre and post kitty) have the same plugs, are you sure that I have an AFR sensor? Wouldn't the plugs be different if that were the case? I sure hope your right...

I just looked through all the books, Toyota, Denso, and some other resources we have here. I will have to admit that you are absolutely correct. There were some 2000 4Runner V6s that still used the old style O2 sensors.

Thanks for squaring me away on this.

TrackRunner · 03-26-2007, 12:50 PM

So what is the easiest way to tell if I have 02 sensors or AFR sensors? I haven't looked at them closely before and I'm not sure what would differentiate the two. I have a 2000 4runner that is federal emissions as well, so I would like to make sure I don't put down the money for a box that isn't compatible.. tia

JHRRLD · 03-26-2007, 01:28 PM

I would say pop you head under your truck and see if both sensors pre and post cat have the same plugs.

mastacox · 03-26-2007, 01:38 PM

Yup, look at the plugs and see how many contacts they have. An AFR Sensor has more contacts than a regular O2 sensor (how many I'm not sure, perhaps as many as 5).

TrackRunner · 03-26-2007, 01:41 PM

thank you for the replies.

TrackRunner · 03-26-2007, 03:35 PM

alright, I went out at lunchtime to check it out, and here's what I found:

- Both plugs are about the same size, and both have four wires going from the sensor to the plugs.

- The front sensor had this written on it:
Toyota
89465
-35530
Denso 0640

- The back sensor (post cat) had this written on it:
Toyota
89465
-35380
Denso 7911

I'm trying to find them on the web to see if they are different. Looks like two 02 sensors to me.. I hope I'm wrong though..

***midiwall*** · 03-26-2007, 04:02 PM

It'll depend on which engine you have, if you're manual or auto, and if you have CA emissions. "Federal Emissions" doesn't mean anything. California is the issue...

Denso's lookup:
http://www.densoaftermarket.com/cata...&model=4RUNNER

URD's lookup:
http://www.urdusa.com/product_info.p...s_id=430006000

Note that the part number(s) you read off of the parts don't match anywhere.

TrackRunner · 03-26-2007, 04:17 PM

From URD's website:

2000 49 State auto V6; Front = 234-4162
2000 49 State auto V6; Rear = 234-4162

'k... but like I said, you need to know if the truck has CA emissions on it.

Did you buy the truck new? and in LA? If so, then it's weird that you have different Denso part numbers front and rear right now.

TrackRunner · 03-26-2007, 04:49 PM

I just got off the phone with Denso and I definitely have two 02 sensors. So I am one of the ones that can't get the AFR Calibrator.

When I purchased the URD Fuel Upgrade kit, they had an option for 95-98 trucks thats included the built in O2 sensor signal conditioner. I chose 2000 since thats what year my truck is (and this obviously didn't include the 02 signal conditioner built in) Does this mean that the FTC1 will not operate correctly because it thinks I have an AFR sensor, when really I don't? tia

TrackRunner · 03-26-2007, 04:53 PM

midiwall: Sorry, I posted before I saw that you had replied.

I was under the impression that since my truck only has one cat, that it does not have CA emissions on it. I bought it used, and they had already had it smog tested. I gave my VIN number to the toyota parts department, and they confirmed that I have two 02 sensors.

TrackRunner · 03-27-2007, 01:43 PM

Just to add to the confusion.. I talked to another Toyota parts department and got one of their technicians on the phone. I gave him my VIN, and he said I have three sensors. Going front to back, he said I have an air fuel sensor, then a front 02 sensor, then the cat, and then the back 02 sensor. I called the first shop again, gave them the VIN, and they also said that I had those three sensors.. Now I'm confused. Is the front air fuel sensor that they speak of not the one that the AFR Calibrator from URD uses to trick the ECU? Or is it a different sensor that has nothing to do with the calibrator...

mt_goat · 03-27-2007, 04:22 PM

Wow, never heard of that before. Have you looked to see if in fact there are 3? I'll buy a round of beer at the next CO4RJ if you have 3 O2 sensors.

TrackRunner · 03-27-2007, 04:30 PM

lol, yeah I haven't had a chance to look. I have a feeling the guys in the parts dept. don't realize that they are listing sensors for CA spec, and non CA spec vehicles. So it looks like three sensors to them, when really they are just listing all the available sensors for that year 4runner.

and as far as that round of beer goes.. I might just have to weld on a random sensor and tell everyone my truck is 'special'

mt_goat · 03-27-2007, 05:45 PM

Yeah actually I have 3 O2 sensors, here's the 2 in the front:

The extra one is for a A/F ratio gauge BTW.

TrackRunner · 03-28-2007, 10:54 AM

hahaha, nice! looks like I will need to be you that round of beer

daytraitors · 05-07-2007, 09:51 PM

I was originally planning on doing the TRD 7th injector kit b/c I was hoping to do it all myself.

Time. . . job. . .

I'm going to outsource this component to an expert who will also help tune the rig (still looking for that guy). Should I return my TRD 7th injector and buy the URD 7th injector?

Should I get a new pump installed? New injectors?

Do I need new spark plugs if I just installed NGK Iridium plugs?

Is there an ECU that will control timing and fuel without having to remap inputs for the main ECU?

d

daytraitors · 05-07-2007, 10:55 PM

I just read that TRD 7th inj. install note.

Does that mean if I have a FED emissions version (with one cat) that I can't use this kit?

Will this be a valid excuse if I want to return my 7th injector (not installed)?

Ok, did a search on google and found this to be correct. Vehicle applications for the 7th injector as well as the installation manual are found on the link below:

I would, if you can, or at the very least get this URD upgrade kit:
http://www.urdusa.com/product_info.p...s_id=110000039

And yes, you need the pump upgrade (very important) and cooler plugs. Are you planning to run the stock SC drive pulley?

***midiwall*** · 05-08-2007, 07:21 AM

And... you should search around the site. Dale, Brian and I have walked a LOT of people through this process before. Check this thread for possibly one of the more detailed babbles:

http://www.yotatech.com/showthread.php?t=111739

It kinda' starts in the middle of the process, but there are a couple of hijacks in there where we take steps back to the beginning with other folks.

Read. Read. Read.

daytraitors · 05-09-2007, 02:51 PM

What are the drawback of the URD Fuel Upgrade Kit and the 7th injector?

the benefits are fairly well detailed on the website, but what about some of the problems and limitations?

I read something about people taking out a fuse to reset the ECU for some kind of calibration reason. What's up with that?

I've got a 2000 Ltd (single cat) with NGK iridiums.

daytraitors · 05-09-2007, 02:55 PM

If I get a bigger fuel pump and use the Free FMU, will that suffice? What will that leave out? Where will I be limited?
