vgt wires

[PetesonM]

Can anybody tell me what wires do what on a he351ve main plug?? I know there lots of people tinkering with them, but I cant seem to find just a simple this wire is power this wire is ground ect... thanks in advance.

I can't help you out, but I'm wondering if your planning on using a vgt on your 2nd gen?

Because it is not. IIRC, it is a PWM system that is constnatly correcting for input. You need a controller to run it correctly. Fleece can probably tell you what each wire does or an FSM for the specific year.

You can get wiring diagrams from Ram's body builder site:

http://www.rambodybuilder.com/year.pdf

pin 1 PK/OR Smart power relay feed (+12v)
pin 2 DB/TN Ground
pin 3 BR/VT Actuator high data link
pin 4 WT/LG Actuator low data link

The data link wires go to the ECM. My guess is that it is a two way communication bus.

JR, yes 2nd gen.Tlane thanks. I have spent fair amount of time reading and its all starting to get fuzzy. was not sure if 351 used PWM or a 341 or maybe it is the same controller. Was planing on using a pot for manual control and map type sensor for auto control. Talked to someone who was running the fleece controller and it seemed rather limited unless they have something new as his was a couple years old. To achieve the correct signal I guess I will need a diff type of translator. Or the unit I have is not good. Any other info would be appreciated if you have experience with this. Thanks

Please keep this thread updated. I also have a HE351 in the garage, but have not yet installed it for the same reaosns. I have heard mixed reviews on the Fleece controllers and do not want to spend that kind of money and be disapointed.

 

[cerberusiam]

Neither the 351 or 341 are VGT turbos, you jave to get into the 07.5+ to get the the VGT's. That desgination is 351VE.

 

[PetesonM]

So now that I have gotten back to this I have a
Red /blue trace
light green/white trace
Dark green
Yellow
Make sense to anybody?

 

[cerberusiam]

Yopu cannot use a pot for manual control because it is a PWM controller. You have to have a controller that does that type of signal and it has to do it correctly based on parameters. You could build something but it would hit and miss to figure out what signal got you what setting on the collar.

 

[PetesonM]

Yep thats correct. I was looking into pwm kits. (Billd your own or pre assembled they have ajustabe frequency and voltage)But have changed gears a bit there is another controler out there that blows fleeces out of the water. And it is cheaper! So I will explore using his. Still wondering why the wire colors on mine do not match.

Link please--

ALSO, I have a Fleece controller waiting for me to install in my garage, got it cheap from a guy after he switched turbos yet again. I actually have seen little or NO negative feedback on the Fleece controller, and it seems to me like a very well built working unit, though like I said I have not installed it yet, but I am wondering why you think it is NOT very good??

 

[PetesonM]

seafish not saying that it is bad just rather limited. Other controler will allow Adjustability of the exhaust brake( how agressive it comes on). Fleece as far as I know not adjustable as far as veins position under boost.( pre commanded) and is not a true stand alone. It relies on truck ecm for control. Other system uses its own boost sensor aka map signal to control vein position and can be adjusted to move the vein at different distances based on boost pressure. Post a copy of instructions for the fleece, I called them to ask questions and must have got the new guy? He couldnt tell me much about how it operated and said he didnt know the lead time if I wanted to purchase one?? He said he just sold the last one today?? kinda a bad customer service first impression.

PetersonM, I don't know where you got your info from, and I am NOT saying that the other unit you are looking at is not as good or better then the Fleece, but it seems as if you are misinformed about what the Fleece can do and how it operates. While I agree that Fleece customer service is not the most forthcoming on the technical details of how the controller works, I thbink that is mostly due to their being the first to market with such a controller and a desire not to give away proprietary information. I DO know that it is a true standalone controller, using only the HE351ve's existing sensors, NOT the trucks ECM for vein control...furthermore, their software DOES allow adjustability of ultimate exhaust brake strength, though not in real time...it has to be connected to a PC laptop for those parameters to be adjusted, then remembers the settings) The same software also allows for different vein positions, thus boost curves, to be programmed based on what the driver wants from the readings of same sensors. Furthermore, the vein position IS real time variable within a roughly 20% range to allow for actual in cab adjustment while driving. Turn the knob one way for more aggressive boost, turn it the other way for less aggressive boost with concordant less drive pressure. IMHO, all in all it seems to be quite a versatile and robust unit, as long as one is willing to spend some time with a laptop programming it for specific truck and driving habits, though MOST people use it just fine preprogammmed out of the box. In fact, before I bought the FLeece, I read ALOT on different forums about different electronic controller for the HE351ve and the they are all going to operate mostly the same way. That being said, one can design and build physical actutators for the HE351ve that do a realtively good job of controling the turbo, but do not have near the adjustability of the Fleece electronic controller. The Fleece controllers ARE relatively expensive, but I got my set-up barely used for $400 so I really can't complain about that either. Of course, I have NOT hooked it all up yet (not enough time, other life, or should I say wife, priorities) to trully know how it functions, but I am relatively sure it will operate as described. Furthermore, while I agree with you that their CS is not the friendliest in the industry, I have read and seen enough about them to know that they will stand behind their products and more importantly BE AROUND to stand behind their products.

If possible, I would still like to read about the controller you are thinking of getting??

 

[PetesonM]

I will get you the info, talked with the guy yesterday seems promising. Did some more reading about fleece. Still not sure what they are using for a reference signal to control the collar. It would appear to be they are using rpm?? Also apears you get a program for a laptop that you can tweek the control till your happy. Thats why I was intrested in the install instructions if you have them.

Sorry didn't catch that you were asking mew for a copy of the instrcutions...I bought it used though, so did not get any. BUT here is a link to the Fleece controller software and the software use instrucitons on Fleeces site--

[PetesonM]

Well electronic motor is bad on this unit have to find a different one before I can play with it.

 

[seafish]

Are you looking for the actuator motor, or a complete turbo?? I think a freind of mine has a complete HE351ve that he could sell you for a fair price...it had 70k on it when he got it, but has decided to go with a Garret instead of the Holset. I can check with him if you want me to?

 

[PetesonM]

Just need the electrical motor part, but for the right price would take it all. Please check. Where is he located?

If PetesonM is not interested in the turbo please PM me the info on it, my cousin has been searching for a good used unit and may be interested.
