DIY: Cleaning up Engine bay...Removing SAI, N249, PCV, EVAP

[Slimjimmn]

so the answer is, NO, you have not had your ecm programmed for emissions deletes

[vr6_nocorrectway]

done the diy now dv makes whip like noise when letting off of heavy boost. but not at 5 lbs. cant find any vacuum leaks either. i have not done any resistors yet. could that throw it off?

[speed51133!]

so the answer is, NO, you have not had your ecm programmed for emissions deletes

The answer is yes numb nuts.
I swear whenever I have a technical question people here give advise like calling tech support....."try rebooting the computer"

The Ecu has all emissions deleted. Yes yes and yes.

Speed51133 - your answer is HERE.

Slimjimmn is missing your question.

[speed51133!]

Awesome. Thank you!

[18T_BT]

sorry..that is 2 prong ,and who said anythign about N80?!

I am talking about the evap pump that is behind the wheel liner. You have to jack the car up, remove the wheel well liner, and it is behind the liner. It is the pump for testing the system, and the pump is THREE pronged, NOT TWO......sorry to be annoyed, but you are annoyed at me for assuming something incorrect.

it is item 1 in the above link, and all the garbage that goes with it

http://www.ebay.com/itm/99-06-VW-Gol...-/290639604503

the above link has one for sale on ebay, and you can CLEARLY see the three prongged plug

I am not annoyed, I was assuming you had the incorrect flow CEL which is caused by the N80 valve (Evaporative Vacuum Purge Valve) since you have all the emission deletes. Most people don't remove the LDP rather cap the hose that runs into the engine bay:



I have all emission deletes and I still had to resistor the N80 valve much like or jump the pins, whatever works.

[speed51133!]

yep, thats the bastard pump i removed!

ill try jumping an outer to middle pin and hope i dont fry something....

this LDP removal jumping of the pins should go up on page 1.....

[Slimjimmn]

just an FYI, the leak detection pumps only purpose is to pressurize the gas tank and charcoal canister to check for leaks.

You need the resistors

[travis_gli]

This question was probably already asked but do you need the resistors if your running say Maestro with the emissions components disabled?

[yeabmx]

can i use this to delete evap and not throw code?

This.

I was told you dont need resistors. I dont have any running maestro all deletes. I was also wondering if it could be messing with me.

[AmIdYfReAk]

The ecu needs the circuit completed, so yes, you need resistors.

[travis_gli]

This.

From what I've been reading if you don't use resistors your LTFT's go way out of whack. However I haven't had this experience personally.

[speed51133!]

it has been said a million times....

YOU ALWAYS NEED RESISTORS!!!!!!!!

now only two components actually need them.......

you can read to find out which ones....

[20VCanuck]

I was told by cts with the big turbo maestro 7 files with emissions deletes you do not need resistors.

I will toss some in for peice of mind. Anyone with maestro want to chime in on their experiences?

[halchka99]

cant you just keep the sensors plugged in and to the side?

This may have been the case from everybody but Maestro users. I haven't heard from any Maestro users about resistoring off such components.

Sort of defeats the purpose of cleaning up your engine bay.

I did a SAI,Evap,PCV, kombivalve, n249, n112, vac-resv delete the other day on my german B6 tank



nevermind the toilet-paper where the filter sits


runs like a champ, cell free I might add

[K20017]

You will need resistors on everything for fuel trims. 330 ohm 1 watt. You don't need a 10 watt resistor! I have been using 1 watt for almost 4000 miles now with no issues.

However, even though the SAI and EVAP N80 circuits have been resistored, you will still get a code for them. Like this:

SAI- Improper flow
EVAP- EVAP leak detection

They will need to be written out of the tune. Then your check engine light will be off and you will pass readiness

[yeabmx]

So will u still get a cel when u put a resistor in the evap sensor?

[K20017]

Yeah, you will. The EVAP emissions test that is run by the ECU uses a pump to create a vacuum in the fuel tank. Since the purge valve (N80) is not present, it detects a leak and throws the code.

[yeabmx]

So who do I send the ecu out to and how much does it usually cost?

[K20017]

I believe most tuning companies will do it, you could just find the nearest vendor and give them a call. I had mine done by Gonzo Tuning in Delaware for around $50.

[l88m22vette]

Eurodyne (my fav) or Unitronic are the best, and both can easily ditch the readiness stuff

[20VCanuck]

Has anyone had any problems with bending the resistor and shoving them in instead of actually soldering them?

[K20017]

I have done that for a temporary fix. It worked well for 1000 miles or so but I wouldn't recommend it since it could fall out completely or 1 lead could come out and come in contact with a ground and possibly cause a fire hazard.

agreed. also, if you have all the deletes in your software, you shouldnt have to resistor anything. I have not resistored a single thing i've deleted in the emissions

[travis_gli]

It hasn't thrown your LTFT's askew at all?

[speed51133!]

you would be getting better gas mialage if you did resistor...

[20VCanuck]

I have nothing resistored and I believe I have all the deletes checked off. I think they were all checked by default when I flashed it.. But I am not throwing any codes because of it so I guess all thats in order. but I have zero fuel trim adapation.

Block 32 is all 0

[TooLFan46n2]

Wow. This thread still blows me away...


You MUST resistor the N80 for a proper running car. The N80 valve plays an active role in how the car is fueled. It must be done.

VVT, SAI, N249 Only need resistors to clear the CE light if you can't do it with software.

[Savvv]

It still amazes me that people are skimping on a $2 electrical device when you only need 4 of them. It is better to keep the entire engine harness in closed loop, period. Don't think you made out like a bandit b/c your CEL isn't on without resistors.

[Pisko]

I used this, plug and play
http://www.intengineering.com/integr...ngle-plug.html

[VWstung]

Those look kick ass^
Might have to get 3 for a SAI pump missing, Evap, and n249 is that isn't coded out.

I just sent my 2002 TT 225 ECU and cash to "reflected" for the delete.
Let's hope he doesn't steal my money

Even though I have a Unitronic tune they won't write a delete file for my car,
Apr doesn't force readiness,
Gonzo never emails back or picks up his phone,

Whatever as long as it works.
