Pulse and Glide - Vacuum
I've got a vacuum gauge tapped into where the fuel pressure regulator is.
I've been using pulse and glide for a while now, and I've had a thought based on something recent I read here, which was to not go into 'boost' as that's just waste.
Does this really apply to pulse and glide?
- Do you want to get up to speed as quickly as possible to glide (throttle 70% or so - reduce restriction..)
- Do you want to get up to speed, but maintain vacuum (say 2-5 inHg - maintain little restriction) ?
If I floor it that vac gauge goes right down to 0, but if I follow it, I can get it to stay around 4 and get over speed and glide.
I haven't been looking carefully at it, so can't say for sure, but my O2 gauge looks to go into closed loop if I maintain slight vacuum). The downside is it takes a little bit to get the speed up.
Which is better?
