7603 torque management inadequate work

Post by V8fan »

Hi guys
Have weird behavior al light throttle if I increase % of torque reduction
In attempt to soft shift harshness (due to tranny hardware mods) I increased reduction and have very long reduction time (1-6 sec) at 1-2 and 2-3 nevertheless table time (0.15-0.25)
Problem is only at light throttle -at full gas it works as should (exept reduction is delayed - or my tranny too fast)
Even if I restore oem settings -it still exist until I not to reflash previous version of my calibrations
I read HPT forum thread about this problem https://forum.hptuners.com/showthread.p ... ent-Issues but it looks nobody knows what to do with this
I used HPT too (cuz it fast in reflashing) but cant load into it 7603 XDF -some errors prevent loading
Is it bug with torque management or HPT ?
Is full flash better than write calibrations only in this situation?
Universal flasher looks much more capable but has so many parameters that I dont know what will change that I not used it -only read and trying to figure out

xdf is for tuner pro to edit bin files read and write with pcmhammer or lsdroid.

always write calibration only unless you have changed something that patches the operating system or are changeing the operating system or are cloneing a paramater block for some reason.

Having said that pcm hammer will only write sectors with changes anyway.
Have you read the FAQ? For lots of information and links to significant threads see here: http://pcmhacking.net/forums/viewtopic.php?f=7&t=1396

I read full by PCMhammer and after that changed by HPT only speed for gears change and TCC lock up and read again by PCMhammer because extended torque reduction come back (about 4 sec 1-2 )
After that in TunerPro compared them and if shows me a lot of undefined parameters that also changed
Please help me understand what parameters also was changed
