Re: Looking for a solution for the Subaru EG33

When you say "tested using console" was there a an actual Subaru IAC hooked up? Yes. It was connected. FW was running self-simulation and blipidle command was used for idle valve testing. Ok. I'll see if I can post a video showing valve position at 0-25-50-75-100% Def not acting as I expected it too.

Re: Looking for a solution for the Subaru EG33

Hi. Sorry I had no chance to check my settings in TS. Spend whole weekend trying to create ini file for my own board. No luck. Also stuck with some strange bug with slow ADC. But I was able to validate that two-coil code is still working in master. Tested using console. You can check my settings ht...

Re: Looking for a solution for the Subaru EG33

I've removed the flyback diodes and the valve moves more. However it does not move in a linear fashion and makes a high pitched squeal. Sounds like the PWM signal. Also I can only close and open the valve to 50%. Can't fully open the valve regardless of manual slider %. Any particular settings I can...

Re: Looking for a solution for the Subaru EG33

Just for diagnostics, if you flip the two inputs, does the valve go to full open instead of full closed? No it does not. Could it be because of the low coil resistance? 9 ohms to center tap. I would think this valve works like a seesaw. More current on one side versus the other moves the valve open...

Re: Looking for a solution for the Subaru EG33

Alright that was it I needed to enable self simulation. The valve does show signs off life but goes to a fully closed position irregardless of manual IAC position changes. Does your meter show different duty cycle or voltage according to your input? Flyback diode time if you ask me. I do see a diff...

Not sure whats up with the 64v gauge reading TPS in TS. Happened yesterday after updating erasing STM32 and reuploading latest firmware. It's not really on my radar right now anyway.

Re: Looking for a solution for the Subaru EG33

Regarding voltage should I be getting 3.3volts on either pin? With the PWM set at 50% I'd expect 6v connected to a 12volt source. Looking at the schematic for Frankenso 0.4 the low side drivers output 5volts. So maybe 3.3volts is what I should expect and its not enough to drive the IAC? Low side ou...

I will try new FW this weekend. But I can test it only on my own HW. So I'll check that nothing is broken in SW only.

Re: Looking for a solution for the Subaru EG33

Looking at the factory wiring diagram it seems I should be applying 12volts+ to the center pin and PWM ground signal to the coils.

How on earth am I going to accomplish that?

Re: Looking for a solution for the Subaru EG33

Regarding control of the stock IAC in the SVX. It has 2 pins labeled OPEN and CLOSE and a third for ground. The OEM manual says to expect 6-7 volts on either power pin with key on. It looks like I'm not the only one dealing with 2 solenoid valves. This fellow ran into some issues controlling a Bosch...

Re: Looking for a solution for the Subaru EG33

Thinking more about the coil and igniter setup led me on a google quest.

I found a post from someone using Megasquirt and his experience with using the default ignition settings. The igniter did not survive.

I cannot explain this :( I see gppwm1_pin NONE on https://rusefi.com/online/view.php?msq=41
What does TS show for GP PWM pins?
Found it!

GP PWM 4 was set to PA0

IDK how or why

Re: Looking for a solution for the Subaru EG33

https://rusefi.com/online/view.php?msq=41 shows gppwm1_pin NONE same 2 3 4, that's good. Something is using PA0 already so you have a pin conflict. Please tell something not to use PA0 In your tune I see auxVoltage1:PA0 auxVoltage2:PA0 place change those to NONE Thank you. I'm going to change that....
