hi, when i got my car and b4 i do anything with it, avg FC was about 11.4KM/L
Tried to maintain driving condition as consistence as possible, drive to work only,
same road, same time, same as jam everyday. Pump full tank all the time, same
station near house, same pump no.5, next time pump full again, measure distance
travelled divided by litre filled to get full tank again. Avg 11.4KM/L +/- 0.6KM/L.
After 3 months using the car, i began making some changes to it.
First i change all 4 tires to new Continental and pump it hard to 300kpa,
still ok though a little stiffer, road grip is fine due to new tire ma, even
at 300kpa the rubber still soft. Then i throw away the mud guard to improve
aerodynamics, throw off the spare tire too, remove the back bumper and now
my Saga Aeroback looks like LMST.
And then all this while i have been hearing engine knocks, looking at the distributor
i saw it tilted to advanced. Each time at low rpm will hear it knocks, more and louder
when up a slope or hill but it goes away everytime when the car got up to speed
beyond 60km/h. At 80km/h knocks will be totally gone. Then i had this problem
that hot starting took a bit longer to crank compare to when cold in the morning.
Sometimes hot starting needed more than one crank.
Then i decided to back off the timing a bit, now could hardly hear a knock but
still got knocks la, just very very very seldom hear it which is a gd things coz
i scare if totally no knocks, i may ran the engine retard, at least now i know
timing is just right, feel good too. And amazingly, backing off timing has eliminate
my hot starting problem! Now hot or cold, crank the same, just one easy short
crank already got the engine to turn over.
And i throw away all plastics from the boot of the Saga, now open the boot and
only see bare metal, totally clean and clear. Now my Saga ratling noise has reduce
a lot, almost like a new car though this is a 21 years old car. And i forgot to mention
i changed all 4 shock absorbers too while changing the tires.
Now the FC, after done all that, it average to 13.6KM/L. I got nothing else to throw now,
weight reduction already near limit. Next i go for leaner tuning with water injection
and then HHO. Not as easy as throw things, but will try to do it somehow.
