I drove 180 km, highway and country road. Yesterday I had cut the battery. In the meantime the ECU has learned itself new. The car drives better and better! It doesn't matter if a few horsepower more, but what is the case. The whole emotional interaction with the engine and the car is different. More bite, a much more direct response, even a different engine sound. Than that is more significant than if it was just pretended. Another effect I noticed is that the engine brake has become much more effective. There wasn't the slightest symptom of a gas failure. It's over. I drive with more confidence in the engine. The human-machine interface is more alive and intuitive. The question is justified what exactly this circuit does, but even without knowing that, it does a lot.

Naturally, skepticism is called for and even desired. But I've had these gas-interrupting blackouts for three years now. And...of course there were times when I didn't have any gas misfires and I was happy with the car. But there is no comparison with now.

Actually it is quite simple. Either everybody else has the correct BPS switch or some have the wrong one like me. It doesn't cost a cent to try if you break the switch by pulling a wire.

It drives differently if you don't work against this circuit. I will install a correct switch.

SFG, you bought a new switch. What did you order? Just a switch, or did you specify whether it should be an NC or NO? Or did you simply order a switch for the brake pedal in the BPS function? It would be interesting to know what you got.
