Hi Stefan!

Sorry for missing this post, I didn't have notifications turned on...

Thank you for adding this feature. It has solved half of my problem!
I have upgraded to fw 2020-11-22 and tried Settings->Save Settings with my "favourite" groups for each control unit. Now, like you say, if I am in Measurement and then go to Settings->Control Unit, change to a different unit and then select Measurement again, it jumps to the stored Group. This is much more useful! The ABS controller doesn't crash any more when the FIS Control tries to connect to it.

However this still does not quite work in my normal use case.
Example: I have Group 002 stored as the "favourite" for my AWD controller on Control Unit 22.
For this Control Unit the mask shows groups 001, 002, 050, 051, 052 [etc].
Most of my Presets are Collections, but I have some single values and Measurements too.
Say I am looking at a Preset which shows a Measurement, E01 Group 031 (fuel-air ratios).
Test 1) If I now enter the menu and select Measurement, I see E01 G 031 - fine, normal, useful. I think this is the most useful behaviour if the Preset is a Measurement.

Test 2) If I instead enter the menu and select Settings->Control Unit->AWD (22), then go back out of Settings and select Measurement, I do not see my stored group G002, but instead the closest available (unmasked) group to G031 which happens to be G050. I think it would be better if this showed the group I stored...

Test 3) Looking at a Preset which is a Collection (six different values all from E01), if I press Reset to get the menu and then choose Measurement, I get a random Group from the six which were used in the collection. I think if you go from a Collection straight to a Measurement it should first show the stored Group, not a random choice from the Collection.

Does that make sense? I can attach my configuration if I didn't explain well. Oder vielleicht könnte ich versuchen, es auf Deutsch erklaren

Thank you!

Hi Stefan,

If I've manually changed control unit and then go to Measurements then I always want to go to 01... it's already a lot of button presses.

In a Preset (for me almost always a collection)
Press Set to get main menu
Go to Settings
Go to Control Unit
Select control unit
Back to Settings
Back to Main Menu
Go to Measurement
- displays "Connecting..."
Get some random group number because you don't know which group was last read in the collection

I never want to go from (for example) group 02 in one control unit to group 02 in a different control unit because there are none in my car that are compared like this. Maybe you do this more often in vehicles with CAN connected to the FIS-Control? For me, as each preset can only show values from one control unit I have almost all of them from the ECU to avoid many different connect/disconnect cycles when scrolling through them.

I don't think I understand your example. I agree when switching from preset to measurement that it's useful to go back in the same group, but if I change control unit and then go straight into Measurement I always always want to look from the start of that control unit. If I went in Presets it would change control unit again..?

Yes, I could make a preset of E22/G001 but that only makes it shorter to change control unit. By definition any time I change control unit by hand, it's because I want to check a group I don't check often enough to have as a preset!

Another good reason - my ABS controller seems to have a bug where it stops communicating if you ask it for a group outside the range 01-07. I didn't manage to make it work until today so I hadn't set the masks for that unit! This might explain some odd "cannot communicate" bugs as you don't display which group you requested until after communication is established...

Maybe this could be a tweak so users can choose?

Great idea! Thanks, I'll try that

OK, no problem. I'll let you know if I work it out

Whoops, that was a typo. It should have read KWP2027.

When I use VCDS it connects fine but says it's using KWP2000 instead of KWP1821, is there any way to force which protocol is used for which control unit? If I can't make it work I may have to just add in the CAN wiring to my harness, I think you said before that it now works with the Golf 4..?

Hi Stefan,

I have another question. Is it possible to do calculations on measured values before display? I realise you already do this for the unit conversions but this is hidden from the user...

The reason I ask is because my engine ECU outputs air-to-fuel ration (AFR) as a lambda value (eg 1.088). This equates to a lean burn of 16:1 air:fuel; 1.088 is multiplied by 14.7 because this is the stoichiometric ratio for gasoline. I can't easily multiply by 14.7 in my head - but FIS-Control could!

If this isn't currently possible I don't know the easiest way to add it in - maybe you could add a 'multiplier' field for each item in a collection and do this calculation before display? This would limit you to only displaying AFR as part of a collection but this is probably the most useful anyway as you may want to look at the raw lambda values in the measurement or OBD views. Your thoughts?

Thanks,

Nick

Thanks Stefan, you're the man! I didn't realise the label checkbox was there. When I ticked them and set everything to upper case it worked perfectly

Now to finish tweaking everything...
