most efficient engine load for a 2.0L Gas

[dmafanp]

so i have a 2011 2.0L Gas jetta, now i know the engine is 20 year old technology so i hope someone can tell me the most efficient way to accelerate, i have been keeping the ScanGauge LOD setting between 75% and 80% when accelerating , is this correct? and if i reach 90% load what does this mean exactly? am i dumping useless fuel into the engine if i hit 90-99%.
Another question, do i shift gears when my engine load decreases to 70% on acceleration or do i push the pedal harder to bring it back up to 75%-80%. are there any charts i can look at for a jetta 2.0 l gas THANKS!

Recommendations like "accelerate at XX% LOD" are only a starting point. You need to find what works best for your car, traffic situation, and shift points.

In my truck, I just jam the gas pedal a little over halfway down, and shift at 2500 RPM. That not only gets me the best gas mileage, but has the additional advantage of keeping up with traffic. YMMV.

very cool, so it really depends on my shift points? so if i accelerate at 80% load and shift at 2000 rpm for every gear that would be optimal? ill cehck other threds for optimal shift point in a 2.0l gas engine

Re. >=90% load. You can check that yourself.

If you pull up closed/open loop on the SCII screen that will tell you - with some inherent time lag in the display - when you are entering fuel enrichment i.e. entering open loop fuel control is the indication that extra fuel is being added.

Stay just short of that load. Up to that point, the higher the load the better.

as stated above, usually accelerate at highest load but in closed loop.
for shift points it depends on each engine.
I checked the BSFC thread but there isnt the 2.0L VW engine.
Brake Specific Fuel Consumption (BSFC) Maps - EcoModder

the closest was the Ford DOHC 2.0L zetec engine (16V).
what it shows is to try to stay in the 1500 to 3000rpm range, but your car maybe different.
some of the smaller low torque engines, like the toyota 1.8L, had lower consumption in the 3000-4000 rpm range.

your engine may be different
