Question1: I have a good quality Mind Impulse Unit and a logis implant. When I activate the logis implant as reaction to get the WS/BS bonus, Do I get the +10 on the tech use roll from the MIU? I think the question here is does the logis implant qualify as "technological device capable of miu linking". In this scenario the MIU helps to get an immediate +10 BS because I am shooting with a gun capable of MIU linking, but I would get 10pct more change of activating a logis implant that will give me another +10 BS, that seems pretty strong and perhaps not as intended ?

The Explorer may use analytical circuits to calculate trajectory
and reactions to a preternatural extent. His ability to read
possible outcomes lets him anticipate the movement of his
opponents. By using his Reaction for the Round, the character
may make a Tech-Use Test to make use of this Talent. He gains
a +10 bonus to all Weapon Skill and Ballistic Skill Tests until
the end of his next Turn. The Explorer must pass a Toughness
Test when he uses this ability or gain a level of Fatigue.
M ind I mpulse U nit (MIU) (RT 150-151)
These devices, also known as sense-links, allow the owner to
directly interface with a machine or technological device. MIUs see
widespread use among the Adeptus Mechanicus who regard them
as objects of divine communion. A basic MIU implant involves
a single spinal or cortex connector, while advanced variants
include wrist connector probes—and possibly mechadendrite
connectors—in addition to the spinal plug.
Common models impose no modifiers to machine spirit
communication and add a +10 bonus to Tech-Use, Pilot, or Drive
Tests used in conjunction with devices capable of MIU linking .
Poor MIU systems require a successful Willpower Test to use
and impose a –10 penalty to interact with machine spirits.
Good models grant a +10 bonus to communicate with machine
spirits, and for Tech-Use, Pilot, Drive, Logic, Inquiry, and Ballistic
Skill Tests when interfaced with MIU systems . In addition, an
MIU gives the user the ability to experience the senses of any
familiars he controls (such as a servo-skull or grapplehawk, see
page 375) as if he were present.
Question2: Do you have to make the toughness test regardless on whether the activation of the logis implant was successful or only if the activation of the logis implant was successful.
