TCU TurboLamik

HELLO
need help
i'm back to my project 8HP70 on 2JZ after few moment and problems with can communication resolved...
now i have problems with error code (20) (speed sensor) and when i shift to drive, the gear target on tuner pro is blocked on 6. Impossible to change. on LCD it's M6
Do you know what can i do?
another problem, i have the number 1 in save mode case.
Any help will be greatly appreciated
kind regards

In tunerpro open up the datadash and in the drop down click analogs. Start live data then look at the analog that is assigned to your program select and note the voltage. Then go to your "Program Switch Call" table and compare the voltage to the program value.

thank's for your answer
i will see with your instruction and back to you the results
