I finaly got time to work on idle.. and it works!! :)
I just got a question about some settings:
- "iac_conf RAW" under Idle setting in MegaTune
- it's the "packed" value of several IAC related flags: (from global.h or varstr.h / magicstr.h):
- uint8_t iac_conf; // iac, bit7:softidle bit6:asym bit5:dualsol bit4=1:ignadv ON, bit3:preciseidle bit 2:stepper(0=pwm) bit1:low_power_halt bit0:power_iac_only_when_move
- when you're on the phone, it's much easier to instruct someone to read (or set to a particular value) this value than list all the options.
- iac_conf=18 (decimal 24), which means bit4 and bit3 are set: ignadv based advance is ON; preciseidle is ON (but not stepper, so PWM-solenoid)
- And how does "IAC afterstart, step per 160rpm" work?
- iac_afterstart_step was a hint to the ECM of how much added opening is required. Use very low value, 1 or 0. It's ripped from recent firmwares. What firmware do you use ? v.13 or so..
- value of 4 means: If you configure +200 "afterstart" RPM, +5 (=4 * 200/160) will be added to the iac reference position. 0 is reasonable, the PID integral (I-term) should have no problem reaching the higher RPM.
