In my prom I have the TCC set to lock at 85 and unlock at 80, but it locks over 100, and anything less it unlocks. The speed is exact 100 from winaldl. Anyone know whats going on.

 

Either your speedo is off(speedo gears in tranny or maybe tire size). Or your viewing your speed on the scanner in kilometers instead of miles per hour.

 

You need to see what the code is doing.
Some have mandatory forced lockups, and some others unlocks, depends on what you have, code wise.

Some TCC is hard coded in the ROM on the PCB.

 

Grumpy,

Thats what I was thinking, All my rpm settings are good, as well as mph settings. The TCC locks and unlocks @ 100mph (no bias at all), so as of now I'm still baffelled.

 

Any one else now about somthing in the 747 code that relates to TCC. I'm going to start searching through the 747 hack, hopefully I'll find what it is. As of now all my TCC values that I can find are good (ie: temp to enable, %tps, and mph). Gotta do some driving on the hiway tomorrow, and with out the TCC locked my stall likes to slip.

 

Ok for now I just set the mph hreshold for the TCC to be unlock (@056E) from 100mph to 75 mph.
