What is the benefit of not doing it off the clutch pedal?
I get it is a little more time consuming, to install but you can use a simple starter button mounted on the floor. I can't imagine how any of you are not either pulling the engine down while it is still on the limiter or the engine is free revving until the clutch gets loaded.
Curious to understand what you gain by putting the 2 step on a separate button. It's not s transbrake so you are asking 3 different systems to coordinate every time you let out the clutch.
These questions are for adults, that are capable of reasonable, thoughtful discussion. For you others, there is romperroom.com and you need to move along. This discussion is not for you.
