Adaptive shift shouldn't matter imo. I think the only reason they do the ratio corrector for these is that the cluster cannot be programmed for tech 2 to a high enough ppk... I have a feeling that Tazzl's software overcomes this limitation. I've been able to adjust a number of different clusters from vz-vz for different ratios without issue. @Sandman has found the limitations of the tech 2 in this regard.Yes and no, totally different operating systems and different communications etc. LS type pcm's uses adaptive shift I believe where the earlier stuff didn't although it was in the software.
Just did a little more reading on pcmhacking.
Jayme:
if you want an easy painless method of having everything work correctly, then leave the pcm alone, you dont really need to touch the ppk or shift points in the pcm. just install jaycar corrector between the pcm and speedo in your dash and adjust it up. all shifts will be perfect and dash will read correctly
Yoda69:
Speedo into PCM is back of gearbox, what happens after this the ECU doesn'r care about, ie. the diff ratio and tyre size.
If the PCM was using the ABS wheels speed sensors for vehicle speed, then would need to redo all thye gear change setting as this is taken post diff.
Both in same thread: https://pcmhacking.net/forums/viewtopic.php?f=7&t=1607
I think speed sensors are very misunderstood.
