E38 5.3 LMG Crank relearn
my swap ( 2007 5.3 LMG/ 4L60E/BCM, underhood fusebox/'07 cluster and lots of the '07 harness into '97 Tahoe) is done, I had the first testdrives and only a few things have to be addressed.
1.) If've got the crank relaern DTC but couldn't perform a crank relearn with the latest EFIlive software. All signals are there ( P/N switch, brake applied..) but the bidirectional control seems not to start. When I don't press the brake the "press brake" message is displayed if I do so it disappears but nothing happens. Is there anything else I have to do? I went through some crank relearn threads but nothing new on this side..
2.) I have no tranny related DTC'S but the torque convertor clutch doesn't lock
3.) the engine seems to have reduced power. On the last third of the gas pedal nothing changes, also no downshifts appear
The only DTC'S I have are the crank relearn and the immobilizer key not programmed, that's all
Any ideas in these topics?

TCC solved another discovered
TCM from 2007 4wd Tahoe OS 24235341 Calibration:24233141
no downshifts when I hit the throttle, no TCC lockup.
I changed the TCM tune to the one that came with the TCM its from a
2007 2wd Suburban OS 24235341 Calibration 24235341
This one makes the difference. I've got part throttle shifts, downshifts with more throttle, kickdown and also the TCC locks. Only difference to my old 1997 setup is that you barly feel the TCC lockup, its very smooth. Big drawback, the cal file is from a 2wd and my 4wd Tahoe doesn't shift at in low range with this tune. What could I do ?
news on that messed up scaling of H0101?
Looks like the scaling on H0101 is messed up. I can reproduce the same fault here. I'm getting Ross to take a look at it now...

Any news on this matter?
