Summary of change:
'''Idle air''' subpage of MembersPage/Skassa The toyota iac is a two coil unit. Can this be controlled ? BMW and audi uses similar iac, and both are controlled. MembersPage/GergelyLezsak/IdleControl controlled it first, now the feature enabled in standard firmware. * "Rob is banking" on the dual-solanoid IAC thing working as the whole IAC thing has caused the first 20v I did to behave very badly at idle. ** what frequency (iacpwm_speed) did you try ? (with what firmware? 00 value is very high frequency again since 1.0.43 or so, the audi valve required this). From global.h : <code> uint8_t iac_conf; // iac, bit7:softidle bit6:asym bit5:dualsol bit4=1:ignadv ON, bit3:preciseidle bit2:stepper(0=pwm) bit1: low_power_halt bit0:power_iac_only_when_move </code> You need to use dual solenoid (bit5=1) with the standard PWM (precise-idle) valve settings. iac_conf=0x78 would be good, but iac_conf=0x68 is better for start (ignition-based idle off via bit4=0). * The needs to be to wires for it, right? ** ? ** with dual solenoid output, there is some restriction with the output selection. The 2 outputs must be neighbors like configure ign/6 and use ign/6 and ign/7 (the latter will be inverted), see GenBoard/Manual/DigitalOut/Table With the injector outputs (injgroups) you have complete freedom (because of injgroups.)

Wiki formatting: * is Bullet list ** Bullet list subentry ... '''Bold''', ---- is horizontal ruler, <code> preformatted text... </code> See wiki editing HELP for tables and other formatting tips and tricks.
