I was test the FRK and rusEFI r.4560 with Tuning Studio on Mitsubishi 4G63.
When the Ignition table = 0 it should be display value about 600-700, Below clip.

Thanks.

710 means -10 (the range was from 0 to 720)

I have just changed it to be more user-friendly, please update dev console. Also dev console has 'Timing' gauge which shows timing without the usage of logic input

How did you get this Tuner Studio gauge? I want to fix it also.

Are you using some wide-band O2 sensor or a narrow-band O2?

I use wide-band sensor.

Did you manage to feed the WBO signal info rusEfi? Do you know the parameters of the analog WBO output? I do not remember if we have covered this.

I am not 1000% sure but it looks like you are running the with rusEfi? Congratulations on being the first rusEfi installation in Asia!

This model have 2 analog output have spec in web.
Within days I had to take the analog signal into rusefi.

I have been using the E85 fuel can be used generally.

Timing degree in new dev it work.

My problem now if the engine is cold, it starts engine very hard.
If the engine hot is very easy to start.

Try changing Cranking Fuel parameters? Does your CLT shows the right value?

Edit: http://rusefi.com/wiki/index.php?title=Manual:Software:dev_console_commands#Fuel_Control has an explanation of the values

float getCoolantTemperature(void) {
	float temperature = getTemperatureC(&engineConfiguration2->clt);
	if (!isValidCoolantTemperature(temperature)) {
		warning(OBD_PCM_Processor_Fault, "unrealistic CLT %f", temperature);
		return LIMPING_MODE_CLT_TEMPERATURE;
	}
	return temperature;
}

void setThermistorConfiguration(ThermistorConf * tc, float tempC1, float r1, float tempC2, float r2, float tempC3,
		float r3) {
	tc->tempC_1 = tempC1;
	tc->resistance_1 = r1;

	tc->tempC_2 = tempC2;
	tc->resistance_2 = r2;

	tc->tempC_3 = tempC3;
	tc->resistance_3 = r3;
}

void prepareThermistorCurve(ThermistorConf * config) {
	float T1 = config->tempC_1 + KELV;
	float T2 = config->tempC_2 + KELV;
	float T3 = config->tempC_3 + KELV;

	float L1 = logf(config->resistance_1);
	float L2 = logf(config->resistance_2);
	float L3 = logf(config->resistance_3);

	float Y1 = 1 / T1;
	float Y2 = 1 / T2;
	float Y3 = 1 / T3;

	float U2 = (Y2 - Y1) / (L2 - L1);
	float U3 = (Y3 - Y1) / (L3 - L1);

	config->s_h_c = (U3 - U2) / (L3 - L2) * pow(L1 + L2 + L3, -1);
	config->s_h_b = U2 - config->s_h_c * (L1 * L1 + L1 * L2 + L2 * L2);
	config->s_h_a = Y1 - (config->s_h_b + L1 * L1 * config->s_h_c) * L1;

How do you calculate the simple CLT.
I feel like the show it does not match the reality.

Posted: **Wed Sep 10, 2014 8:08 pm**

tempinfo should show CLT calculated resistance, please tell us what the value is? Please also disconnect FRK and measure the resistance between GND and CLT wire. Let's make the sure the resistance is calculated correctly.

Posted: **Thu Sep 11, 2014 10:38 am**

bias resistor can vary, as long as rusEfi has the value of YOUR bias resistor

tempinfo should show CLT calculated resistance, please tell us what the value is? Please also disconnect FRK and measure the resistance between GND and CLT wire. Let's make the sure the resistance is calculated correctly. We need this info.

close console, restart rusEfi, open console. Is it connected to the right port - does it send any commands? analoginfo?

That's some great data here!

The values are not that far off, to make them better you need to make the top temperature setting more accurate (I will now rename "temperature3" to "highest temperature")

Let's try C=120.0 R=100.0 as highest temp setting, I think I saw that value in some datasheet.

Once again, great information!

As you see this got us closer to real values. I think we are good enough, in order to get better values we need more precise data on the sensor.

Posted: **Thu Sep 11, 2014 7:24 pm**

This value ok.

How to check set_cranking_fuel_min and set_cranking_fuel_max?
You have command for check?

Posted: **Thu Sep 11, 2014 7:36 pm**

Same tempinfo shows the cranking fuel parameters. I've just changed fuelinfo to show current cranking fuel value at current temperature, but you would need latest version 4633. Please note that this version would reset your configuration to default.

I am working on improving the update process so that configuration is not reset that often but this is not ready yet.

Now everything works correctly.
I want just the engine mivec control functions only.

Posted: **Thu Sep 18, 2014 2:22 pm**

Sure, let's get you http://en.wikipedia.org/wiki/MIVEC

Do you know if your engine is an earlier two-profiler system or something continues? http://en.wikipedia.org/wiki/Variable_valve_timing#Continuous_versus_discrete?

You would need to figure out electronic characteristics of the control mechanism - is it low-side or high-side driving? Is it PWM or continues signal?

I want to open solenoid at 5000-5500 RPM output signal GND to solenoid.
It can use low-side output GND .

I want to implement EGT gauge within the next couple of days and then some simple GPIO would be next - GPIO would let you run your simple VVT. See https://sourceforge.net/p/rusefi/tickets/95/

Posted: **Sun Sep 21, 2014 8:00 am**

If the shift light function can I use instead mivec .
If possible, I want to have two channels.

I am really interested in some details on this

For example, have you driven your car under runEfi power?

I am done working on EGT but now I need to figure out something for my own mule - I would be buzy with that. Do you have any software developers to implement a first basic version of GPIO which you need for VVT? I can write down how I see the first trivial implementation so that any available developer could implement it.
