All,
I have connected the CAL. SWITCH for quite a while but I cannot get it to change correctly from CAL01-CAL08.
I am almost sure the settings are correct but for some reason it displays CAL05 on 2 settings and sometimes CAL06 on 2 settings.
1) CAL01, 02, 03, 04, 05, 05, 06, 07
2) CAL01, 02, 03, 04, 05, 06, 06, 07
Settings are:
Positions used: CAL08
Input Pullup: ON
Threshold Voltages: 0.2V - 1.0V - 1.5V - 2.0V - 2.8V - 3.4V - 3.9V
Stabilisation Time: 500ms.
Just so I understand it correctly, The levels of the thresholds should be set in such a way that the actual CAL.Switch voltages are right in the middle of the set thresholds, correct? EG. CAL01 = 0.015V, CAL02 = 0.61V, CAL03 = 1.23V, CAL04 = 1.83V, CAL05 = 2.44V, CAL06 = 3.08V, CAL07 = 3.71V, CAL08 = 4.28V
So CAL01 is below the first threshold and CAL08 is exceeding the last threshold and the rest is right in between.
Please advise.
Best Regards,
Jasper.
Cal Switch settings
Re: Cal Switch settings
For what it's worth, my CAL thresholds are set as follows:
0.364V, 1.072V, 1.681V, 2.19V, 2.79V, 3.202V, 3.611V
So yours do seem out of step. In theory, the steps should start at half a diode-drop (0.35V) and increase by about 0.7; but in practice the values do need to be tweaked, as I understand it.
The best thing is to add a gauge measuring the actual CAL switch voltages, take a note of what they are for the 8 settings and then, as you say, choose a value halfway between each measured voltage as the values you enter.

Re: Cal Switch settings
Hi Tim,
Cheers for the reply. At leat it seems I understand it correctly. What is the reason to add a gauge for reading the voltages? I thought it would be more important to check the voltages that the Syvecs reads back from the Cal. switch as this is what is used for determination of the correct Cal. position, right?

Re: Cal Switch settings
Are we not saying the same thing? It's CALSwitchV that I mean: the voltage as read by the ECU, and you then use that to calibrate your CAL switch 
Re: Cal Switch settings
Hi Tim,
I wasn't being clear. Yes, we are talking about the same thing
I somehow thought you were talking about an external gauge. I am quite sure that my thresholds should work but I will start with the values you gave me and try again. Thanks!

Re: Cal Switch settings
You are correct in your assesment of what is required.
CAL01 = 0.015V - Thresh01 = 0.3v
CAL02 = 0.61V - Thresh02 = 0.9v
CAL03 = 1.23V - Thresh03 = 1.5v
CAL04 = 1.83V - Thresh04 = 2.1v
CAL05 = 2.44V - Thresh05 = 2.8v
CAL06 = 3.08V - Thresh06 = 3.3v
CAL07 = 3.71V - Thresh07 = 4.0v
CAL08 = 4.28V
But remember it will need to see the voltage for over the "Stabilisation time" to register the change.
Different CAL switches may require different setups as they can be two or three wire, with diodes or resistors so you should always check your cal voltages on a fresh install.
CAL01 = 0.015V - Thresh01 = 0.3v
CAL02 = 0.61V - Thresh02 = 0.9v
CAL03 = 1.23V - Thresh03 = 1.5v
CAL04 = 1.83V - Thresh04 = 2.1v

Re: Cal Switch settings
I have tinkered around with the settings again and I still cannot get all the positions to show correctly.....
I have checked the Voltage of the CAL.SW at each position and put the thresholds RIGHT in the middle as also recommended by Pat. Same happened as before.
Cal01, 02, 03, 04, 05 are fine. However the next notch is yet another Cal05 whilst I can see the voltage changing and it is stable too. It just doesn't change. Then the next notch after that makes it change to Cal06 and the last notch changes the position to Cal07. I can NEVER get Cal08 working except when I remove the Cal. switch completely and get 4.96V there which makes Cal08 active.
According to the Calibration the "Cal. Sw pigtail" is connected to AR4 (which I assume is a resistive, pull-upped input) and in the IO config is designated to AN16.
These are my thresholds after checking the Voltages step by step and calculating the EXACT middle point each time:
0.3V - 0.88V - 1.445V - 1.99V - 2.51V - 3.015V - 3.49V
If anybody has suggestions what I can check, please advise.

Jasper.

Re: Cal Switch settings
What does CalSwitchV report for all 8 positions - just to double or even triple check your threshold choices?
Re: Cal Switch settings
It sounds like you are missing something here.
Look at "CalSwitchV" if it is above the top threshold in position 8 you WILL be in CAL08.
However there is one thing I thought, you need to do a "Device->Program" before the cal switch thresholds are used, so you need to set them properly then program before testing. You can also check for electrical noise on the cal switch, and set your filter to 100% on the input for testing.

Re: Cal Switch settings
Hi Tim,
My CalswitchV are: 0.015 - 0.59 - 1.163 - 1.718 - 2.251 - 2.763 - 3.253 - 3.727
So according to these values the settings should work properly.
Paul,
You might be on the right track here. It DOES make sense now that I think of it that the device should be programmed first before Cal. switch settings take effect and the results from it changing on the fly when doing the thresholds could be a large threat to the engine whilst running. I am going to try to program it and check again. I will keep you posted.
Cheers,
Jasper.
