Summary of change:
------ 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. And how to configure it in megatune? * 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 [http://wwww.kapsi.fi/~mpeippo/vems/to_peter.msq 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? My own answer The Reference table was set to 1 (all CLTs) so the IAC valve was not able to produce me some RPM increase. Now this rpoblem is solved,but i need some finetuning hints,and basically i want to understand how this feature works. I want that with cold engine it starts like a champ,so i set the reference table -40c to 90% 77c to 85% i also want that the engine RPM below 40C set to 1200RPM,so "Idle cold RPM" is 1200 Max temp. for cold idle speed is 40C With warm engine 920RPM will do the job nicely "Idle RPM warm engine" 920RPM Min temp for warm RPM is 70C What is idle afterstart? now set to duration 15s added value 150RPM IAC actuator speed? now set to 50 max steps to extend? now set to 255 What i notoced is that tough the warm engine RPM was set to 920 and the engine CLT was above 70C ,and TPS was below 3% the engine current RPM was 1050,BUT THE IAC STILL SHOWD 6-8%DC!!!! Which setiings can tell to the IAC that in situations like this he can close and override the reference position tables 10%??(because of the still opened throttle valve)
