HPDi Idle adjustment

[GasCan II]

Before I adjust the idle on my twin 2001 Yamaha 150 HPDi , I was told the computer controls the idle on these motors and there is no simple linkage adjustments. Just checking before I screw something up. Thanks for any help!

what you heard is correct
do not screw up the sensors

what is the problem with the idle?

One motor is idling @8 and the other is@7rpms.
So I’ll leave it alone .
Thanks

Negative on the computer controlling the idle speed of an HPDI model. The throttle valves are all mechanical. There is no idle air control valve.
