Stuck with Switch In's and other

V3 SOFTWARE
1

Hello,

Stuck with some troubles and questions:

  1. When I press clutch pedal (it’s connected to switch 3 by ground), AC turns off shortly.

In log its looks like shortly switching of switch 1 (where is the AC IN is connected).

Firstly I stuck with problem that Switch 2 was connected with Brake pedal by Power (12v as stock wire for Toyota did) and it turns off 1&3 that is connected by ground. I did inverion for the switch 2 by relay. This problem gone.

But this problem I dont see any parametr for this. Is it a bug or an interesting thing with connection? The wire of clutch switch goes from ECU Ground through pedal stock oem “button” at pedal and goes around to ecu to switch 3 input.

  1. Is there any opportunity to choose filter from CAN analog inputs from CAN Switch board v3, i connected there a some pressure&temperature sensors and its a little bit oscillate - want to filter it just for comfort.

  2. I use onboard UEGO and have a habbit to look at AFR, and when its full lean - it shows 7.2 AFR.

  3. Does Ignition Correction curve (by Ign Angle) work by 0,5 angle? Or it only shows it by 0,5? And for the main ignition advance the same question (I’m not sure that there is important to work by 0,1 for exam

    ple, but still interesting)

  4. Why if I want to turn off only the PID or overdrive a Idle Airflow it stops even a ignition correction by curve? Is there an opportunity to be cofident that my correction is work properly without any help from other systems?

  5. May be it would be good to ignore AC Press parameters to stop work AC system if AC press status is unassigned - I get it out that it is a problem, but…

  6. In future is there any plans to upgrade the log viewer inside V3 studio? In would be good with oppotunity to delete before or after chosed moment, may be search of parametrs (like a list of parameters and for any of it it would be great to choose search greater than or less than). Sometimes its diffcult to search something in 1-2 hours log file.

Log, project and the picture pinned.

Big thanks!

The first point the most important

1. If you use internal EMU BLack switches you cannot feed them with the voltage. They need to be grounded to activate.

  1. There will be CSB V3 new firmware with the built in filtering for analog inputs.

  2. I will check. It should be fixed in the latest version but I will check to be sure

  3. All ignition calculations works with the resolution of 0.5deg as well as spark calculation. In the other words ignitiona angle resolution is 0.5deg. Some strategies works internally with higher resolution (eg. ramps) but finaly the value is rounded to 0.5deg

  4. The idle control is qute complex as the airflow corrections (PID) follow the ignition angle to ignition target error. However override airflow settings shouldn’t disable ignition correction. I will check it.

  5. It is good idea.

  6. In the next build there will be many GUI improvements. Also there will be new toptic created here to gather all ideas how to improve the GUI and the workflow.

Great thanks for the answer!

But still I have the problem with the AC that turns of when I push the clutch pedal (clutch switch is on), in goes from ecu ground through the switch and to switch in (ecu).

Now all the switches connected to ground.

Could the connection of the switch in to 12v damage the ECU?

or I should connect a diode or smth like that?

P.S. The picture and the log are actual.

I add option for debouncing times for switches it will fix your issue.
