Now i will have a little time for upgrade the car.
I want to use a stock Audi Bosch Idle air valve,2 pin,cigerette style.
How to wire it?
- Stock idle air valve is pwm style. Connect other pin to +12V, other to free injector channel.
- Choose PWM/Stepper from idle settings, choose PWM type and correct idle solenoid channel under Iac hardware setup
- In idle control PWM reference table, fill in values 60 down to 30 linearly decreasing, these need some tuning but something to start
- try to check other idle setting from [this msq]
idle air solenoid - wired
I "manually" opened it with 12V, it cliks, so it's functional! I also measured its impedance: 4.1 ohm.
Pin1 to Ignition Switched +12V
Pin2 to EC36-pin6
I tried to set to PWM as discribed, and i choose INJFET #7.
Configuring for Injector Driver #6 channel. See GenBoard/Manual/DigitalOut and GenBoard/Manual/DigitalOut/Table
- iac_sol_channel=0x70 (injfet 7 in MegaTune; you did this fine)
- EC36-pin6 mask is 0x40/64 as in (Inj G) GenBoard/Manual/DigitalOut/Table
- so set decimal 64 in 7th (starts from 0, so last) index of the inj sequence table, or expressed in tables.txt (as in mct):
- h[0]=xx xx xx xx xx xx xx 40
I can measure 12V between Cylinder Head and "Pin1".
Progress
Ok , i set that h0 so it works now,but only in on/off IAC valve mode,it really pushes the engine from 900>>>to 1500 RPM.
PWM mode
I also tried different PWM freqvencies from 10-255,no luck.
Note,that i have taken special care of engine variables,set everethigh (temps,RPMs i mean) insane high,but with PWM its not working.ANY ideas?
