Found the Accufab hanging idle problem

[George Klass]

I found ONE of your points actually correct, #7. Other than that, I can tell you respectfully that you are full of sh!t on the other six points, LOL.

I would be happy to discuss all points in detail. Again, I love Accufab products. I use them and recommend them to others.

However, my posts have proved that Accufab's set screw calibration process needs improvement, and the installation instructions need revisions. This is reflected by Accufab customers who continue to post hanging idle problems after purchasing Accufab throttle bodies and following the installation instructions.

Please professionally consider these items I have posted for the benefit of your customers.

Thank you Bill. #5 is relevant. You have to consider that a digital multimeter may not be accurate to 0.01 DC volts.

Bill is correct, I agree with combining those points. Although the statements are correct, I should revise them into 1 point for better clarification.

Thank you Bill.

When the throttle blades stop against the throttle body case part of the time, and the set screw part of the time, idle is erradic. This was seen on 99Shindoda's car.

1.00 volt is the upper limit of Accufab's recommended TPS voltage setting. The point is valid, as it addresses Accufab's instructions.

I respectfully disagree. Ford vehicles come from the factory in this range. I have posted information and a datalog of a Ford vehicle idling perfectly in the lower part of this range. I can review this information if you wish.

[George Klass]

I have posted the instructions on how to correct idle problems on this very site. As to 03steve's advice, I don't know any professional way to tell a guy that he is FOS, other than to say, he's FOS.

Thank for you debating the technical points of this discussion Bill.

I can only speculate what Ford's tolerance is for TPS voltage range. Again, I have posted a log of an unmodified factory throttle body at .926 volts. This was set by Ford.

It does matter, because properly setting idle is the subject of this discussion.

Ya get the jest of what I'm saying?
I'm not trying to be an AZZ or come off as just being right. Ya just can't make blanket statements on what WILL work.

I understand what you are saying.

In a #/min MAF EEC, you need to scale engine displacement when the meter is seeing greater than 64#/min of air. If you do not do this, load will no longer be properly calculated by the transfer function once 64#/min or greater is reached.

However, the MAF transfer function is not a TPS sensor. What I am saying about the TPS sensor voltage does apply to all Ford vehicles. I will be happy to provide more examples of other vehicles idling properly in the 0.90 - 0.97 voltage range if you wish. They are using stock untouched Ford throttle bodies. Again, this is the same range is I recommend for all throttle bodies on all cars.

I do enjoy reading about how a high performance component should be calibrated, on a car full of other high performance components, based on how the Ford manual says that a stock OEM car should be calibrated.

This makes good sense to me. Would someone please pass the bong, I need a hit.

George,

The TPS voltage and set screw discussion applies to any throttle body, stock or aftermarket, equipped on a Ford vehicle with a stock computer. I imagine this covers 99.9% of your Ford customer base.

Other performance modifications to the vehicle are not relevent to the setting of the TPS voltage, or the throttle stop set screw.

wait wait wait... yep, still no problems whatsoever with my Accufab. I've taken it off a few times for other reasons and never made a single modification to the unit since it was shipped to me. For once it appears I actually got lucky. All the other mods that no one has problems with, I've had problems with

Thread officially derailed...it's about time.

I would pick on birdman about the IAC restrictor plate he has on his car, but I don't think he likes me very much.

[George Klass]

This is America, a place where people are free to believe anything they want. The four funniest things that I have ever heard in this context are that 10% of the population believes that Elvis is still alive, 8% believe that if you sent him a letter he would get it, 6% that believe that OJ was innocent, and the one guy that believes anything that 03steve said.

Mr. professional sounding car guy /on

I've glanced this thread for the last few days and have enjoyed the technical discussion.

George Klass: I am aware that you are some kind of resources / representative for the Accufab Corporation and in a way helped with the forum by posting documentation that may resolve issues related to your throttle body product.

Though I appreciate the effort to aid the users in resolving their issues, I feel that the lack of a technical rebuttal to the other members post regarding their issues deficient.

The talking points of the calibration methods without the forethought of the effect heat would have on a metal device, the use of general purpose electronic measuring devices to complete the installation of your product that may not within reason, be able to accurately measure your request / required specification for trouble free use, the perceived inadequacy of the documentation that you provide with your product, all seemed to have a very elementary canned response, that doesn’t address the afore mentioned points.

I feel that it would be in your best interest to directly address the issues that have been present to the forum as not only shine the best light on both you, your product you represent, but your company as a whole.

Mr. professional sounding car guy /off


slacker internet racing type dude /on

Klass .... Dude.... WTF

All you can say is that another guy is FOS and that you've posted the instrutions on the net.

Earth to corporate guy,

post some realz ***** up on what these peeps R' talkin bout, if you cant man up then get your baby bottlez, sit in tha corrnerz bro and STFU. that trottle bodyiez gets hot like FIRE bro, its going to do a transformers more than meets the eye on y0 *** and mess up all that stuff. we can have must up stuff bro,

mad respect for y0 skillz an all with workin for tha man, but your game is weak if all you can say is someone is FOS. and cant keep it real bout what really going down. get one of the Supercalifragilistic expialidocious engieer type dudes to skool you on what these cats are talkin bout

[George Klass]

If I had any clue as to what you were talking about, I'm certain that I would be happy to respond.

He's saying you should respond with technical reasons as to why Steve is FOS as you say. So far, he's impressed me. How about a mature technical rebuttle other than saying he's FOS.

Agree.

I was one of the very first playing with the POS ACCU"FAG" TB and I addressed about every aspect of the induction process, from ajusting MAF Counts, Idle, Voltage DL, IAC, replaced pars and tune with no luck.

Since then, I got rid of the TB since I felt that there was no support. Now, I see Mr. Klass with the opportunity to provide some insight or technical know-how in the topic at hand. Since I "assume" that Accufab has actually attempted to troubleshoot the problems to provide an actual fix. But instead decides to call names and what not....if that the way that Accufab does buisness, then they will not get my hard earned cash.....ever again.

Naz

[George Klass]

OK, steve may not be FOS as I original suggested. He may be completly, 100% incorrect in his assumptions, but he may not be FOS.

I don't know steve from Adam. I'm sure he's a great guy, in fact, I would love to have a beer with him someday. But, I'm not going to try and get into some kind of technical discussion about air flow, CFM, "hot air gaps", IAC's, TPS's, or any or all of the parameters that we could discuss for days on end, none of which has anything to do with installing a throttle body anyway.

I have, on the other hand, addressed the two primary issues relevent to the throttle body and how to decipher if the "hanging-up problem" is a mecanical issue or a calibration issue, how to seperate the two, and how to correct the latter.

[George Klass]

As to Naz, this proves once again that there are some poeple that should never be allowed to work on their own cars.

[03Steve]

Thank you for the response George. I see where you are coming from.

I have to say though....what I have posted are results and facts, not assumptions. This information will fix hanging idle when the Accufab instructions don't. The "seven points" on page six are 100% fact. By disagreeing with them, you are basically saying:

-All digital multimeters are accurate to 0.01 volt
-Heat does not expand metal
-1.00 volt is an acceptable setting for TPS voltage
-0.98-0.99 are acceptable settings for TPS voltage
-The set screw calibration is always correct from the factory and never needs to be adjusted
-Accufab's instructions always solve any hanging idle problem after the product is installed

I invite you to discuss each of these items I listed above, starting with the first one.

Are all digital multimeters accurate to within 0.01 volt?

You obviously haven't seen Naz's car.
