CRD swirl motor resistor ????
 
Ok so i seen this on another thread and i didn't want to high jack it but it sounds interesting to me and I was wondering if anyone else has done it and what does it help with....also how do I hook it up and pics would be great to
And do I need a tune to put it on

I would also get a 4.7K ohm resistor for your swirl motor and you will have one bulletproof WK CRD.

The resistor is connected to the live and signal wires which are red/green and grey on the crd, these are actually the two center connections on the plug, and it is a four pin plug with three wires

That would be me who suggested installing a 4.7K ohm resistor in your swirl motor plug. I was told about this by a fellow member and read about it on the 300C forum. A bunch of guys in UK are doing this and having good results so I figured I would give it a try. I followed the instructions on the 300C forum; they have pictures as well, and have been running it for over a week with zero problems. You unplug the connector at the swirl motor and install a resistor between those two wires and it fools the computer in thinking the motor is still hooked up and working. The swirl valves default to open when the vehicle turns off. This mod keeps the valves open and no more swirl valve issues to worry about.

This way I have the ultimate CRD setup. No dpf, no egr, and now no swirl motor worries. This motor should last forever. Now I just need to install my methanol injection setup and clean out all the crap in the intake that accumulated before I deleted everything.

Some members have been talking about the GDE tune and how it disables the swirl motor. Well this is a way to get around purchasing that tune and still disable the swirl motor.

I was looking at the wiring diagram for the EGR throttle body and it should be the about the same setup. The throttle body necks down to about 2” with a butterfly valve. It’s supposed to help with egr mixing and flow, but only really reduces flow. However, the biggest offender is the egr duct into the air charge pipe. It a huge restriction in the intake track to help the egr flow into the intake.

I am curious the legality of selling a connector for "Emergency Use Only"

One of my biggest fears is being a thousand miles away with the family and travel trailer in tow and having the swril motor go out and truck fall into limp mode while being out in the middle of nowhere. Think if nothing else will make a connector with instructions and soldered to spades and kept in the glove box for when it does happen.

hmm interesting..
curious to hear more

who is gonna be the guinnea pig?

See tnadanzig's post above. He's been running with the resistor for over a week:)

I will try to get some pictures of my install, but its pretty much the exact same as in the 300C forum. I don't think it would be illegal to sell a connector but I don't see why you would need one. Those companies market as off road only. However, I wouldn't have something like this stored in my glove box. I am running the resistor mod at the moment and I don't ever plan to take it off. If anything I plan to remove the swirl valves from the intake manifolds once I get the time to pull them.

Where did you get the resistor? RadioShack? D you put it inside a male plug or have it kind of loose like the one pictured on the 300 forums? How can you tell it worked and the swirl flaps are open? Thanks.

ahh ok i mis-read it
i thought he meant people over there have been running it for a week with no problems

my mistake, reading too fast lol



i would love to see install pics, and yea...how do u know its working? and where did u buy the resistor?

how long was the install?

terrasmak 06-13-2012 11:06 PM

So if i read this properly , you install the resistor and leave the plug off.

tnadanzig 06-14-2012 07:27 AM

TurboDiesel, I will try to get some pictures probably not till this weekend. We are trying to sell our house so I don’t have much time lately. I will post them as soon as I get them, but it looks just like what they did on the 300C forum.

I know it is working because the plug is no longer connected to the swirl motor. I installed the resistor between the two wires and no DTCs. It didn’t take that long ~ 30 min, but the hardest part was getting the plug out, and then taping the resistor to the plug. I have AutoEnginuity to check and all good. I got my resistor from digikey, but had it for some time in my tool box. I play with some electronics stuff and I luckily had some of the right flavor.

Terrasmak, yes, you leave the plug off and just jumper two wires with the resistor and tape it up.

I would like to come up with a cleaner more permanent solution. I am not sure what I would like to do, maybe cut the plug off and solder the resistor between the wire and heat shrink or find the opposite connector and make my own device. Not sure, but this will work for now.

If you can find a number on the plug, there is a good chance of finding the manufacturer on the Internet.

How did you solved problem with egr valve? How to take it out of sistem without throwing a code or puting engine in limp home program?

tnadanzig 06-14-2012 11:09 AM

I am running the Custom Spooling Tune with dpf and egr delete settings.

awesome thanks for the info
thats not bad at all...once u find the right wires....u can buy 100 resistors off ebay for less than $2 shipped lol...i may see what i can find locally.

did u just tape the **** outta it with electrical tape? or what tape did u use?

tnadanzig 06-15-2012 09:45 AM

Yup, I just used electrical tape. I know you can get resistors at Radio Shack, but any electrical supply house should have resistors.
