What year are we talking here? I have Alldata at work.

You know, the Dodge engineers maintain a presence on srtforums.com, there are dedicated forums to ask them questions in. Now, Holset is owned by Cummins and are supposed to start being badged as Cummins at some point in the future, so this doesn't guarantee you'll get to speak with an engineer about the circuit design, but it's a real chance to see if you can get a Dodge engineer to give you a referral to a Cummins/Holset engineer.

2008 with the variable geometry turbo (not sure if its an option or standard).

Somehow I don't think they're going to give me the serial communication protocol for the Holset actuator. That's privileged information and likely non-public. Not that it couldn't "leak out"...

Re: 95 TSI AWD Project VGT Holset no 56k
 

It may be, good point, but I am almost wholly certain that in the near future it will have to use a standardized protocol by law.

Re: 95 TSI AWD Project VGT Holset no 56k
 

What? Are you saying there is legislation that will take effect somewhere in the world that regulates the message format of a variable geometry turbocharger actuator? ???

series8217 all of your post as of right now are solid; time for you to go make a intro post, dont disappoint :6

I prefer to keep most of my projects on the down low until they're nearly complete. I tend to get more work done that way. My car will remain naturally aspirated for at least another 4 months. Expect to hear something around that time.

My friend has a Fiero with a dohc v6 hybrid, he also says it has the biggest reground cams anyone has run in them. Its a fun car, so I'll definately appreciate seeing the fruits of your labors later on.

BTW my Holset arived today, the UPS guy was kinda pissed. I weighed it at 51lbs... this thing absolutely dwards my current S-trim. >:D

Re: 95 TSI AWD Project VGT Holset no 56k
 

There are only two or three guys running those cams.. who is your friend?

Re: 95 TSI AWD Project VGT Holset no 56k
 

Thanks for all the information. Hopefully someone will be able to use it to help figure out how to really use one of the stock actuators.
