Hmmm.. i am manual... keeping my RPM at abt 2800 driving abt 100km/hr on gear 5 on highway... i pump my tank at abt 50 buck once a week when i reaches 1/4 tank... fuel consumption abt 14km/l... i think its good enough...

hmm.. i always have this thinking that lower gears use more fuel.. the higher the RPM, the more fuel consumed. therefore i always change gear at around 2k.. Guess i need to try out this method and monitor

if u apply 10,000N of force to get a slow acceleration, u travel 500m to get your desired speed, total work done by car is F x distance = 10,000 x 500 = 5,000,000 J of energy if u apply 15,000N of force to get a shiok acceleration, u travel 200m to get ur desired speed, total work done by car is 15,000 x 200 = 3,000,000 J of energy Do the math, i prefer shiok acceleration Apply more power to get ur desired speed at a shorter distance. My auto 1st gear to 3rd gear change is always about 2.5 - 3.2prm If I'm not wrong, my pica reach second lamp post is already about 55 - 60km/h Hmm.. Just to share.. A few months back, I did a test to acquire some data on how acceleration affects the FC.. I tried one with heavy foot, the other with ultra light foot.. Ultra light meaning that it's feather light.. Very, very slow acceleration and had to keep to left lane to avoid being high beamed by frustrated drivers behind.. Each test runs for one week.. So after 2 weeks, I compared the figures.. There is a difference, but the difference is only 1km/ltr.. That means being feather-light, I gained only 1km per ltr of petrol burned.. This is not worth it IMO.. The consequence that I suffered is that when I try to resume back to normal driving style after the ultra light test, I find that my pica feels slow to respond due to the driving pattern.. Have to reset ECU.. Therefore, after the test, I continue the way I drive usually.. No need to be ultra light..

hmm.. u mean the car battery? how to remove the (-)? if put back will have spark? I was a signaller last time and use the car battery to power the signal sets in the rover.
When connecting the jumper wires, will result in sparks! scary

Try a bottle of Redline SI-1 fuel system cleaner. If your fuel system or injectors are dirty, it might help restore fc.
Also check all your tyre pressures are correct and not too low.

Should remove the positive first. Cos when put back, the current will not flow in a reverse matter and this the spark will not be so big. Lucky army taught me well else kaboom. Lol

Lol You should never remove positive first. Bcoz the negative is connected to the chassis. Always disconnect negative first. Otherwise you may injure yourself if you lean on the car (negative) and touch the positive.

sparks are not uncommon. only must isolate urself properly and do with gloves.
my cerato FC was 11+ when i do featherlight. but after SJ-CAI and now keeping 2.5-3krpm shift, it is very slightly better abt 12. also since i get better control of this massive 1.26 tonner i get to work faster....less time on the road, less time idling, more shiok, more wind, more boomz music. I have also used redline fuel system cleaner and that tank was great, but subsequently fall again. now i am on another product, this tank also great, but what i want is the after-effect.
if this product proves to be worthy, can find it on the cerato kangtao thread!

i do get better mileage when using 92 compared to 98, my theory is 98 is more refined & clean, so burn easily compare to 92. however i think using 92, the engine gets more sludge deposit and becomes less efficient... so in the long run, ur fc will also become worse too ... correct me if i'm wrong

92 has less resistance to pre-detonation as compared to 98. For Picanto, 92 is more than enough, unless you have a high compression ratio car, then no choice you have to use higher octane.
98 or premium petrol usually have a bit more cleaner, I think bcoz it can sell at much higher price.
92 actually has more volumetric energy than 98, although many people will not think so.

Hmm.. If want to reset ecu, can try the fuse box method.. I cant rmb the procedures.. I only know that you have to take 2 ecu fuses, leave for 3 minsbefore putting it back abd restarting the car.. Oh.. Must tap the brakes a few times after the fuses are taken out..

Safety always come first before anything else.. I never rev past 3k when my family and baby is in the car.. If not, when I drive alone, usually drive faster..
