another 96 riviera tuned!

so this past week i was able to get a tune from tony with his DHP PT. we ran a few scans to see where i was, and then uploaded the 1.5 bin. i can really feel a difference at WOT, or coming out of a turn with skip shifts now
i believe i only peaked KR for a brief second at 93mph during the 2-3 shift. KR was at a max of 2.6*. not too bad seeing as though my engine has never seen RPM's up there before. the rest of the time it was 0KR no matter what i did. even the scans before the tune had 0KR, but we only ran to 65/70mph (on 25mph back roads )

tony if you could upload any of the scnas that would be cool, but from wht i remember i had LTFT locking at .78 WOT or cruise and it was +-3 at other times.
boost consistently maxed at 11.6psi even with just a 3.4 and after 3"DP,plog, and no cat.
the only value that looked out of whack was my air/fuel was 10.5 at WOT, i believe that is too low.
it was ~95*F outside with pretty high humidity btw.
on the way home i hit 120mph with no problem and plenty left in her, but roads and traffic stopped me from staying in it. (my tires are H-rated btw)

so if anyone can help me to start tuning that would be great. i plan on getting another tune come winter time before i go to the track again. do i need to MAF tune or VE tune or just make small adjustments? and is my A/F way out or is that normal? how much timing can i adjust?
TIA

oh and when we first uploaded the 1.5 the 1/2 shift was set at 5800rpm IIRC, and when i punched it in 1st i hit a rev limiter/redline. it defiantly felt horrible so we backed off the shift points some. just a word to the wise if anyone else is using the 1.5 on a 96. does anyone else have that problem with their 97/98's?

10.5 A/F is pretty normal, but not ideal. And remember that's command, not actual. You don't want to be advancing timing any more unless you don't see knock at that value.

+/- 3 LTFT can be fixed with MAF tuning. You want it to be between -3 and 0. No positive values. Locking in at 0 during WOT is pretty easy once you have the cruise LTFT figured out. Remember to do idle LTFT before anything.

The 1/2 shift error probably has something to do with the MPH vs. RPM values. To fix, lower the MPH value.

These are conditional shift values that say you must satisfy both values to shift. For example, if the PCM is set to shift at 35 MPH and 5800 RPM, the trans will pass 35 MPH and then shift at 5800 RPM, because it will be at well above 35 MPH by that point. However, if you program the PCM for 60 MPH and 5800 RPM, the trans will wait until 60 MPH, even if it revs above 5800. If your rev limiter or fuel cut-off is set at 5900 or 6000 (a good idea), you'll experience it backing off at that point. If not, you'll keep revving until you reach the limiter value.

I'm a little confused...I thought our '96s had vacuum assisted transmissions, not the electric controlled like the '97+, so they couldn't be tuned for shifts, ect....

shift pressure is controlled by vac in the 96's, and they have modulators out for that. i was still able to up the rpm/mph value setup in the pcm. there are not as many variables to change under the trans area on the PT, but a few are still there.

nice! I didnt know that!

(I just changed my modulator valve this weekend...the old one must of failed awhile ago because when I took it out and shook it, it sounded like a rattle can...I guess the diaphragm must of failed. Now it shifts nice and firm)
