Jerry has explained that several TCU variations were available over the years causing inconsistancy in TCUs and TCU mod results.
not sure why there would be any differences. the entire driveline computers and suspension come right out of the discontinued slk32 amg's. i can swap parts with the srt and the part # are identical. the issue with yours could be the modded tcu's. perhaps theres a file that was messed with that caused the limp mode. i had latemodel21 (chris) ship me his oem tcu from his spare slk32 and it worked without any issues at all. reinstall my modded tcu and all my datalogg issues returned. i can easily swap the tcu with jhm2k new srt-6 and confirm the swapability or not when rob sends my thermalcoated intake parts back.
