Max Load and Max WGDC Base

What is the max that can be set for each respective table in the subject line? Is a WGDC Base setting of 58 the max? Also, is 200 the max load target? How does the D and P factor affect the WGDC? If I want faster spool, can I increase the WGDC in the upper left hand corner to bring on boost faster.

This is a good start to learn ATR http://www.e90post.com/forums/showth...highlight=jake

WGDC base - can be set up to 100% I dont recall the name of the value, but there is another parameter that is like WGDC max value, by default its set to 58% You can increase this value, and PID will have more authority to add WGDC to meet requested boost.

Load target can be increased above 200, but even at 200 you are requesting a load value that OFT will not achieve.

PID is not easy to explain, read this - http://en.wikipedia.org/wiki/PID_controller

I'm not using ATR, I'm using Tuner Pro, but I think that's not important. When I look in WGDC Base, that is where I see the 58. My understanding is that 58 is pretty much a fully closed waste gate. Is that correct?

It looks like the 100 you are referring to might be in the WGDC to WGDC Position Table.

The WGDC Limit % is 57. So maybe I am confusing this number for the WGDC Base number above. Can the WGDC Base be set above 58?

Yes they can be. You can drive the boost control solenoid at 0% Duty to 100% Duty.

The WGDC Base is editable to accept values up to 100% Duty however the WGDC Limit Table will set the max value the DME can run regardless of the fact that there might be higher values in the Base table.

Thanks. So can you go higher than 57% in the WGDC % Limit Table?

But base of 57 translates to about 75% to the solenoid... You shouldn't need to change max DC unless you are really pushing the turbos... Plus ATR will not allow enough load generally where you'd need 75%.

This is actually not correct. The WGDC limit table is the limit for PID WGDC%.

Yes. I personally raise the WGDC limit table to 70%, but leave the base table alone. PID will jump up to 70% during spool up, so adjusting the base table is really not needed.

Thank you very much for the correction, AWTT335i.

Much appreciated.
