GN Boost control setting recomendations

[TurboDave]

Now that I've had the TPro up and running for several weeks, and man is it running GOOD!!!!! I thought I'd run the boost control wire and start it's setup.
I have the BstC in the car now, so running the TPro wire and plugging into where the BstC control wire was hooked is no problem!!

I just need some recomendations for all the various settings to get started.

Here's what I got.
Considering my wastegate actuator is probably a 14# base spring.
And condidering I can safely run 19+ # of boost on pump gas, and I like quick spool, what are the settings I need to look at?

TPS spool: Probably 2.5 like I have the BSTC set for.
RPM spool: 2450-2500?
TPS start: 4.0???
PSI start: 16-17#???
DC% start: 30-40%????
PSI set: I want to run 20# but with a 14# spring, do I still set it for 20????
Gain: ???

Thanks guys!!

P.S. My butt dyno says this car is running incredibly stronger than before, not only part throttle but WOT also.
Very little tuning adjustments were reuired. Basically -2% across the board, and +2% afterstart.

Dave, you will find the pro's boost control (being closed loop now) worlds above the bstc.
Your settings are all pretty close, set the gain about 18-20. If you want 20lbs, set it for 20.

Thanks JC!
I forgot to ask, the first parameter in the Boost Control section is MAX RPM, and it came defaulted to 0. It isn't in the manual. got any idea what it is? Maybe a future use?

Alot of new features in 4.8 that don't do much for the buicks.

Thanks, that's what I figured it probably was.

Here's my settings, and the observed results.



Gain = 15

DC% start = 40

PSI start = 16

PSI set = 20

TPS start = 4.0

RPM spool = 2465

TPS spool = 2.5



When punching the throttle (<10mph), the boost immediately jumps to 20# and then pulls back to about 15, and then more slowly works it's way back up to the 20# set point.

It holds the set point nicely, but that pull back, I'd like to get rid of.



Any ideas??



TIA

Try the gain at 20 or even 22, see if it helps.

DC start is too low.

Thansk guys. It's started raining here (finally), so when I get a chance to take it out, I'll report back.
Man this thing pulls hard!!!!!!
