brotanThe engine die off so far, heard few things:
1. If you turn key immediately to start, will kena. Need to wait fuel pump sound off, or the ABS light off.
2. Some say caused by faulty PCV, ask SC to change. This cause also mixed with engine over-crank during cold start.*
3. Some say caused by ECU, need SC to reprog ECU and TCU.*
* SOS: LYN Preve and Saga forum.
Save fuel during city drive for this car is very tricky, mostly dealing with acceleration from standstill. Comments from RS Dynotune is that CFE engine is tuned to cun-cun 14.7 AFR, so IMO it doesn't command much response when accelerating.
For my car, the above you quoted were the things I learned, and I can only do 11~11.5 L/100km now. Based on the above, here are some contexts:
1. Traffic is slow, press fast on pedal let the car reach the right speed, relax the pedal and cruise. Can manage 3.3L/100km at constant speed.
2. From #1, traffic starting to move faster. Apply 3rd rule, then relax the pedal to cruise.
3. If climbing hill, make sure the speed is at least 60kmh. Can manage <13.7L/100km between 60~80kmh. Any lesser, the FC is higher.
When acceleration from standstill, I switch to SAT and notice the clutch engage at 1k RPM, to pickup more efficiently.
Cruising on highway also switch to SAT mode.
When downhill, SAT mode
sometimes have lower engine drag.
for the die off, the no 1 maybe can explain when just want to start engine. but if already drive for some time, still happens, also possible caused by the same thing?
regarding the FC, for no 3, you mean if speed less than 60kmh, the fc will be high?
