When to P&G vs just drive

[jcp123]

P+g is tricky for me with the slush box. I usually do a steady throttle input up and down the hill unless I have an unusually steep grade.

That's where I'm at. 2850 to be precise.

Yep. P&G helps even more the worse your gearing is, and the more overpowered your engine is. Compared to the Metro, I have both - poor gearing and a big engine.

I never glide up a hill unless it's a hill I can't really tell is a hill, because my engine gets about 50%-60% load in 5th when I can tell there's an incline and that's good enough for me.

lol, into Reverse? :P That's the gear under 5th for me, which makes the engine spin at 3250rpm for 60mph.

Just hit the handbrake first

I'm planning to use a kill switch and eofc my next trip and see what happens. I still compare dwl up hills sometimes and feel that p&dfco gives me better results, keeping in mind my civic has a relatively high rpm.

I have a feeling this is wrong. The reason P&G works is it maintains momentum, whereas DFCO doesn't. Keep in mind that OBD instrumentation is woefully inaccurate most of the time. When I first got my TDI which has virtually no engine braking (you can barely tell if it's in gear or neutral - simular effect to turning on the A/C while DFOC'ing a normal car), I tried P&G in DFCO for the first tanks, but P&G in neutral (EOnC) netted clearly better tank to tank results, even though SGII showed the opposite effect.
