I have been in contact with Fleece performance (company that sells the controller) and they still havent made anything universal. Their current system runs on the stock truck's CAN-BUS or whatever they use.
It would be nice to have full control though. All the way open at cruise to drop EGT, closed at idle for noise reduction, partially open until need for fast spool.
I am working on learning the PID programming. Right now its just trial and error and a ton of reading and asking questions. Thanks for letting me know I am not doing it right though and pointin me in a better direction. I need that. I actaully want this thing to be properly set up to do what I want it do do, not a big giant work around to trick the ECM into doing what I want.

Either way, if his target boost is past the MAP, he'll end up running openloop wg anyway, and PID programming will be a big waste of time  Marcellus: do you plan to run your turbo past 2550 mBar? |

Map limit? Yes. So its a big waste? What should I use instead?

Set your requested boost to max, and tune the last row of your wg linearization table to the wg profile you want.

You're going to have TERRIBLE part throttle response with that map.
In particular, you should NEVER go from a higher value to a lower value for a given input RPM over a range of non-linearized wg inputs.

The whole map or the last row?  Its is a rough example just see if I am getting what you are saying. |

You really want to have *some* response to the PID in operating ranges where the req boost will be under the MAP...

No. And all that 95% at low rpms also makes no sense.
A perfectly linear WG system would be 10 in all 10 column cells, 20 in all 20 column cells, etc.
you should *start* with that, and work out what areas are non-linear.
Honestly, though I feel you are really out of your depth. I'm not sure there is an easy way to explain to you what this table does. Do you have a math or engineering background? That might help me figure out how to explain it to you based on what background you have (through analogies).
Then, the next step would be to talk to the WG manufacturer to provide information about it's response characteristics.

I am sorry man. I am a CNC programmer/machinist/Tooling guy. I thought that since I set theRXN to max that it was only going to pull from the last column. I figured the rest of the table was irrelevant at that point, or thats how I interpreted what you said. Also, I thought the 95% at low rpms was what I wanted. Am I wrong in thinking that at 95% the N75 is pretty much blocking the signal? Then, at higher rpms the duty cycle should loosen up to stabilize the boost? I guess this is the reason why I just went MBC last time I was trying to dial in my car. This time I would really like to figure this out.  |

FWIW, I wasnt trying to deviate to far from my base tune and the few tunes I have been looking through:  |

At low rpms the PID should be sending 95% already to the INPUT of that table. Am I wrong in thinking that at 95% the N75 is pretty much blocking the signal? Then, at higher rpms the duty cycle should loosen up to stabilize the boost? Yes. Look, before you do ANYTHING to that table, do you understand what the two inputs to that table are? One is RPM. The other... what do you think it is? |

That linearization table is a mess.
