DBW evo8 p&p - error 77 APS(main) /APS(sub) tracking Error

Hallo everybody,

i've got error 77  on my new evo8 g4x tuneing, but I can't undertand why! My pedal have 2 ouput signals where 'sub' is 50% of 'main'.

Signals looks good, but why APS error accumulator grows in this way? Is this driven by difference grater tha 6% between main and sub voltage or scaled percentage?

and after that reach faulty delay and stops:

Your screenshot shows the APS sub covers the full range of pedal movement so the APS (Sub) 100% setting should be set to 100% for this pedal.  You would only set it to 50% if you had a pedal where the APS sub output only varied voltage for the first 50% of pedal movement and becomes static above that.

Yes, you have told the ecu that the APS sub should read 100% when the main is at 50%, but the signal it is receiving does not reflect that.  If the signal does not match the expected signal then the error accumulator will continue to increment until the signal is corrected.
