URD Kit Question

[Stevo3]

Wasnt sure where to put this post, so mods, feel free to move it where ever.

My question is, Does URD offer discounts for being a member of UltimateYota or other non-specified Forums? I fugure while my supercharger is off being rebuilt i may aswell bite the bullet and get the fuel mods. let alone get close to 300hp outta my beast :clap:

I wouldn't count on it, but sometimes they give deals on stuff so nothing wrong with asking if they have anything they want to get rid of. Don't forget to get a 2.2" pulley with the URD kit and you'll be able to push around 320Hp at the crank with a good tune.

If you're an Auto you're going to need the VB upgrade as well... unless you take it easy on the throttle which isn't as much fun...

[Stevo3]

Got a 5 speed here :), yeah the 2.2 pulley will be later down the road after i get the rebuild and urd kit mostly paid off. Let alone ill be learning how to program the ecu with the laptop myself. so i need to take it one step at a time. Hopefully i can get a discount on the kit. that would make my day! if thats the case the pulley would be ordered aswell hehehe

I don't want to rain on your parade, but you'll need a little bit more than just the URD kit to tune your engine safely. It is best practice to at very least get an aftermarket wideband oxygen sensor kit to measure the AFR in your engine, and an OBD-II reader. This could push your cost up to about $1800 if you get the Fuel kit with IK-22 spark plugs and the FTC1-E, Wideband O2 sensor, smaller pulley, and scan tool.

I don't think they give any discounts to any groups that I'm aware of.
I have seen used URD kits go for sale on eBay though so check there too.

So, a laptop could not be used as an obdII reader? and now i would have to replace the o2 sensors? what other fine print things i need other than the urd fuel kit? i thought thats all i would need for it being a "kit" and being able to tune it with a laptop?? now im just confused.

They're not really fine print, it's just that by itself the Fuel Kit doesn't add the necessary engine metrics you'll need to be able to effectively tune the engine. "Tuning by feel" is definitely NOT an option.

The BR3 OBD-II Scan Tool that is sold on URD's website requires a laptop to display what it reads from the vehicle's computer. You also need to get a wideband oxygen sensor and gauge to be able to see how much fuel you have to add/subtract from the engine; I have the Innovate! Motorsports Stand Alone gauge kit and highly recommend it.

For everything you'll need to tune your engine properly, here is the approximate price breakdown you'll be looking at:

URD 3.4l V-6 Supercharger Fuel Upgrade Kit (FTC1-E and IK-22 plugs included): $1146.00
Innovate Standalone Gauge Kit (LC-1 and XD-16): $399.00
OBDII BR-3 Scan Tool: $93.00
Stainless steel exhaust bungs (for additional oxygen sensor): $5.90
URD 2.2" Supercharger Pulley: $139.99

LoTek Dual Gauge Pod (for boost and WB O2, from gaugepods.com): $54.99
Painless Wiring "Cirkit Boss" Aux. Fuse block (for all components, from Summit Racing): $62.95

Total: $1901.83 , not including possible taxes or shipping.

It is worth pointing out that URD's prices are VERY competitive, and unless you find a used kit on Ebay, it's doubtful you'll be able to get all of the components above for cheaper. This is also assuming you have the necessary tools and skills to install everything yourself, including soldering the electrical connections for all of the components.

Basically, you have to pay to play :angel:

Okay, so ill be xing out the 2.2 pulley... I thought the piggy back computer that comes with the kit was able to check the AFR from using the laptop. And wouldnt i be able to splice into my current o2 sensor to use a different afr gauge? and for the obII scan cable and software i can borrow that from a friend.

[mastacox]

Minus a little then...

Nope. The piggyback FTC is able to modify the fuel going into your engine, but not read the direct AFR.



And wouldnt i be able to splice into my current o2 sensor to use a different afr gauge?


Using the stock narrow-band sensor as a tuning guide is a dangerous mistress. You can add a simple gauge that shows "lean-stoich-rich," but its reading is unreliable at best, and inaccurate at worst. To tune with a narrow-band o2 sensor it is also necesary to add an EGT gauge, which can be an expensive proposition. You won't really save any money by trying to use your existing narrow-band sensor, since a wideband setup is MUCH more accurate, easier to install (getting the bung installed at an exhaust shop only costs about $50), and gives you a secondary source of AFR so it's easy to see when your stock O2 sensor is going bad. I highly recommend going permanent install wideband; you'll be able to see problems before they occur and get a safer more reliable tune from the engine.

The biggest argument of all for wideband tuning is that Gadget's U-Tune guide assumes you have a wideband AFR sensor. Being able to use this guide is a great advantage for anyone who wants step-by-step instructions for tuning their engine.



and for the obII scan cable and software i can borrow that from a friend.


That will save you $93 then.

I forgot to mention, you might consider getting URD's 7th injector kit (http://www.urdusa.com/product_info.php?cPath=79_80&products_id=1260518512) instead of the fuel upgrade kit. It will save you a bit of money and make tuning a little bit easier (but not necessarily better).

BUT (and this is a big one) it doesn't include a way to fake out your stock oxygen sensor for closed-loop boost. Translation: you have to buy either a SplitSecond ESC1 ($189, and I haven't heard good things about it) or live with a possibly dangerous "dead region" in your powerband.

[Stevo3]

Well the problem with getting just the 7th injector kit would be the fact that the first gen superchargers didnt come with the port for it. So I have to X that one out. Good thought though.

[Stevo3]

Hrmm where did my other post go. Well ill just repost it??

Got off the phone with Brian from URD. Came up with a set price on everythin i need to program and get everything to run and opperate correctly. dont need to get the FTC1 unit cause he said its built into the new AFR unit or something along the lines of that. So yeah, well see. I just need to save up a couple more hundred now to get both the S/C rebuilt and get all the fuel mods.

You need the FTC1 because it's what you control fuel delivery and timing retard with. I think you mean the LC-1; so they're coming out with some sort of new FTC1 that has a built-in wideband oxygen sensor controller? Does it still have a built-in oxygen sensor signal conditioner also?

[Stevo3]

as i said, something of that sort, and Brian told me he just got off the phone with their supplier and said that something was built into something and one of the things werent necessary anymore. I have him sending me a list of the items that he included in the complete kit and extras needed, so ill let you know when i recieve that list. I dont know much about reprograming and all these devices. I just told him i need everything toget the full function. And he told me everything that i would get and need. But my dumbarse didnt write anything down.

[Stevo3]

HAHAHA go figure, I went to cash my paycheck yesterday, And the teller tells me that im pre-approved for a credit card. With a limit much more than needed for the URD kit and extras. So.... Looks like ill be getting the 2.2 pulley after all. And maybe the double pod for the AFR gauge and boost gauge :clap:

I'm getting pretty excited about this now! Gonna have a fresh S/C and a bunch of mods to install!

Hey Christian, I may be needing your assistance in the near future!!! There will be beer involved :hillbill:

[MTL_4runner]

Steve, we want to see PICS!!!!!

[Stevo3]

There will be, ill be taken a few of them just so i remember where everything goes :hillbill:. Hopefully ill be getting the card next week sometime. The day i get is will be the day i order everything from URD. Then hopefully ill recieve everthing before the weekend so i can start the project! Shipping shouldnt be more than 2 - 3 days cause im only one state over.

[96 Runner]

Hey Christian, I may be needing your assistance in the near future!!! There will be beer involved  :hillbill:


Root beer? :) Not much of a drinker, but hey, I would be happy to help if I can. Too bad the stinking temps are up. My 4R hates this weather and was pinging the other day with my winter map. I had to switch to my summer map and plug my deckplate (this 'activates' the elbow mod and draws in 'cooler' air from the fender, or so I believe). Went from -5 degrees timing to -10 in places. Yuck.

[cougarfreak]

Is TRD refreshing your SC or someone else? How much? If someone else, who?

[Stevo3]

TRD doesnt actually make the superchargers, They had Magnuson build them. So itll be sent out to Magnuson for a rebuild. And im not 100% sure on the price. From when 96 Runner had his rebuilt, Ill have to take a guess at around 600-700$ for the rebuild, not including shipping.

[cougarfreak]

Thanks for the info. I developed cracked heads a couple of years ago after 40K miles with the SC and took it off. It's been sitting on my shelf in a box waiting for the pockets to fill with the $1800 necessary to purchase the URD kit and tuning schtuff. I've contacted Magnuson and I'll post the result.

[Stevo3]

Sweet, id like to hear what they had to say. And what generation of S/C is it? Mine is the Gen I (grey). So im not sure if there is a difference on rebuilt costs from both.

[cougarfreak]

I have the black gen 2

[Stevo3]

swizzle, id like to swap someone for the 2nd gen, but thatll never happen anytime. But yeah, let me know what magnuson has to say about your S/C.

[cougarfreak]

what's the common problems with the gen 1's anyway?

[MTL_4runner]

Leaky nose drive and noisy gears.

Ok since this thread is a few weeks old and Stevo3 has his other Fuel upgrade thread Im going to threadjack this one. :D

Guys (and/or gals) I have been reading sooooo much on this and Im not the brightest crayon in the box so Im asking for a little help on getting things cleared up. So I am buying a used 2nd gen. Supercharger with about 8500 miles on it. (Ive only paid for half so far). Well the current owner (whom builds turbo kits) doesnt have any trd or urd upgrades all he has is dynamic tensioner, standard pulley, and (a Turbo technology FMU. Boost dependent fuel pressure riser. nothing major, just helps at full throttle.) Thats quoted from him. Anyways through all my research and reading the engine needs its help with a system at all times, closed/open loop, to prevent pinging, afr, etc. etc.

So this is the part I need help with. I have a few options to choose from

OPTION 1:
-URD Fuel Upgrade Kit - it also gives you the option to choose the LM-1
-LM-1 (which is for Air/Fuel Ratio tuning. This uses the bung welded before the O2 sensor correct? And is this what people create the maps/tables with and enter values on the table? Or does this just trick the ECU into thinking its getting the 14.7/1 stoich?)

-So for option 1 would this be all I need?

OPTION 2:
-URD 7th Injector Kit - which also gives the option to add LM-1 and/or an AFR calibrator (would this be the URD AFR sensor calibrator and how does it differ from the LM-1?)

Which option is better to go with? And are there more things I need?

When they say in the kits it includes (URD Performance Calibration Unit) Is this the FTC or whatever? And is this what you use to change the individual map cells?
Mastacox you mentioned the OBDII Scan tool - Will the Scangauge II work for this cuz I have one of those.

I guess what Im really asking is What exactly do I need to make my engine run well, what do I need to tune it, what do I need to monitor it (I believe just AFR gauge is needed and boost and trans temp are just nice.)Also a big part is trying to understand what each device does and how it works?

Im not going to change pulley size right now because thats not critical, VB for my tranny will be done down the road -I will just take it easier for now,

I know this is a long post and I dont know if it makes much sense, and I do know it is a huge covered topic. But Im confused, call me stupid if youd like but please just help me figure out what I need while calling me stupid. Thanks in advance.

[Stevo3]

I would highly recommend getting these mods, For your option one: If you are getting that booster for your fuel pump and just the LM-1, I dont think the stock injectors can possibly push out more fuel then they already do.

The 7th injector kit is an option for you though. I believe URD found a good way to use it to its full capacity but has not released it yet??? You may want to give them a call and ask about that one.

You will need a Wide Band o2 reader, I got the Innovate one from URD. The portable one, not the permanent. I would also just get the walbro 190 fuel pump because your pushing the stock fuel pump past its limits with the the booster. Then your will need a OBDII reader that can give you readings while your engine is running. Pretty much to let you seen when it goes into open/closed loop. And then you will also need some sor of piggy back computer to control the fuel/timing.

I beleive what Ive said is true. If Im wrong someone else will chime in :)

When you say that booster, you are referring to the URD Performance Calibration Unit that comes in the kit correct?? And is that unit the "Piggyback" controller I always hear about? Or is the piggyback something separate I need to buy that doesnt come in the kit such as the URD MAF/Timing Calibrator (FTC)?

Ya their 7th Injector Kit is out for purchase but I think I want the regular upgrade kit that way I get new injectors that I know will be up to the task.
And I will add the LM-1 as well. As far as OBDII I have the scangauge that does tell you open/closed loop. Do any of the units you purchase plug into the OBDII port as well cuz if so I dont know how to have both those units running on it then?
And that should be everything right?

I think Im starting to get it. Thanks for the help so far.

[Stevo3]

Yes, the URD kit comes with a brand new walbro 190 fuel pump. It also comes with the FTC1 unit to control the fuel/timing.

I made the mistake of calling it the LM-1, the LM-1 is the wideband fuel ratio o2 sensor.

And from what i hear, If you do get the complete kit, you wont regrete it :D. It will also allow you to run the 2.2 pulley which will ad about 2 - 3ish psi and another up to 15 hp.

All i have left to do with my kit is wait for the s/c to come back from Magnuson and slap that puppy back on and start tweakin with the FTC1 and get it into tune. Should be getting the s/c back next week thursday hopefully! I cant wait to see what the hype is all about with the kit :hillbill:
