Thanks guys, all solved!
My problem was that the accelerator throttle didn't reset to the starting point!
And so this staggered the distance then with the stepper motor!
I leave the photos here to understand each other better as I don't know English well and I'm using a translator.

Well lubricated the throttle body and the stepper motor and then reset the tps settings and it returned to move correctly between 0.60 and 0.72!

Made adaptation reset, now the bike is perfect! The minimum drops as from the map!

Thank you all, super kind!

Step 1 with stepper motor retracted and throttle closed you set the tps
Step 2 with stepper motor applied you set the stepper motor adjustment.
With both set proper the .5mm may or may not be correct depending on wear of these componets that's why i say forget about the .5mm cause more than likely you will screw up the tps settings.

Step one you retract the stepper motor with tuneecu tps about .62
step two that is just the normal position with ignition on engine not running tps should read with adjusting about .74 adjust the nut on stepper motor to achieve this.
forget about the .5 mm of play

Thanks. I adjusted the stepper nut all the way off and couldn't get the stepper numbers to change much. Also same thing with another stepper motor.
I need at this point to get it running and sync throttles and adjust tps a couple times to get it dialed in.
Toyota starter arrives tomorrow!

something don't sound right maybe your tps (throttle position sensor) is not correct or is wrong in some matter.
when you work on your starter you will have to remove the front gear of the toy starter and install the rocket part.
this is just info that i want when you pull the rocket starter off take a channel locks and see if the Bendix/sprag/or one way system will turn free one way and get hard to turn the other direction.
