Hi guys, I’m having trouble getting the anti lag to activate. I’m pressing the allocated can switch and I can see this in the log but it goes from ‘disable’ to ‘not armed’ back to disable. All of the settings look correct for it to start but I don’t understand why it won’t go into ‘armed’ state.

It looks like your can switch doesn’t turn on, look at its state in the log, when it was “Armed” it turned on

what engine u use?

I use a non latching switch, maybe this is the issue 🤨

I will change the switch setting to latching 🙂

Engine is a VW 1.8t 20v. I’ve never use ALS before so I’m guessing a lot on this one.

this should work, otherwise everything is fine in the ALS settings, don’t forget to adjust the cutoff ignition and fuel enrichment and maybe raise the throttle in the map DBW charahteristic
