no. I was saying, I doubt my SE is optimized for the best shift timing...

"Performance Mode" does not mean optimized for best shifting. It is simply the normal shift points for that model year. Turning it off means the car is shifting sooner and getting into a higher gear for mpg reasons. The 00+ models don't have a performance button to kick down into a mpg save mode it simply runs at the normal shift points all the time, hence no "Performance Mode" button. That is why the DHP or other PCM'* raise the shift points to get it into the optimized shifting range for real performance...

ok.

2000 + SSEi'* do not have a performance shift button. It is always in normal mode.

The following is a direct response from DHP.

Pin 21, that'* good to know. I will connect a switch to mine.
....he blew up his trani.....see guys, another trani problem. Better install a cooler.

SilverBullet, is this pin 21 only after a custom pcm or is it for stock too?
and what does the quote refer too? a prior post?

I thought there was nothing to change with the shift pattern on the 2000'*, that it is already in performance mode :?:

The info on the pin # came from Slamking18 in this post near the top of this page.

I believe it is only after the custom pcm is installed because it is a special programmed feature.

Only with the DHP reprogrammed PCM.
It is definitely not already in performance mode.....but maybe GM would like you to believe that.

I will try to contact DHP directly to find out exactly whats up with this

I prefer to deal with ZZP. They have very quick delivery and great delivery service.

10 days delivery was stated.

Don't forget that Zoomer is a GTP expert but he doesn't know Bonne'* that well.
.....or at least the guy that answers Zoomers e-mail.....I really wonder if Zoomer himself actually answers the E-mail questions. :?:

Let'* face it, not too many guys who buy Bonnevilles mod them, so the aftermarket is not that familiar with them....yet.
Like Will once said.....squeal like a guinea pig.

I'm already out $400. on that Jet Module that only works with non supercharged 3800'*.

I just got a response back from DHP and they said that their module does not explain how or where to connect the switch and refered me to www.clubgp.com :?
