I'm getting 10km/l.... so 400-450 for a full tank is very good i think.

Try tracking your mileage using fuelly.com - it's easy and you can see trends and patterns.
It's been discussed and proven over and over before, so called fuel enhancers does little to improve FC. Most are placebo effect, and the only real fuel enhancer is your right foot. Did you measure the FC accurately to determine that you really do get 40-70km more per tankful? or it's just rough estimation? QUOTE(AzeL @ Aug 23 2012, 08:45 AM) But for auto, especially auto on old cars like ours its expected to have lower mileage right? Hmm..just pumped just now (40L)...tracked 429KM until indicator light up....actually even for me the mileage is very good considering on Monday I went on a road trip with a lot of mountain driving (about 250KM~)...maybe due to the fact I changed my compressor and just serviced my car 2 weeks ago haha. So assuming I used 40 Litres for 429KM that would be about ~11KM/L I used to use fuel enhancers from Cosway and they generally give me 40-70KM more mileage on a full tank, but some of my friends say maybe not good so I stopped using it...are any of you here using similar products? |

You need to measure accurately to determine if the fuel enhancers work. I've used those tablet type of fuel enhancer before, useless no effect. And read up more on FTC.gov and other sites and most will tell you they all DO NOT work.
http://www.ftc.gov/bcp/edu/pubs/consumer/autos/aut10.shtm Not sure what you mean by car engine option is model engine.... normally ours is Gas L4... QUOTE(AzeL @ Aug 23 2012, 09:01 AM) If we're talking about accurate measurement, then no. What I did was, full tank, drive till indicator lights up, refuel. I normally check against the distance I've gone through until the indicator lights up, which normally does when there is ~6 litres or less fuel in the tank. This post has been edited by poolcarpet: Aug 23 2012, 09:05 AMI also made sure to drive normally, no sudden jimat2 attitude when I use the enhancers, because I do realise there might be the possibility of a placebo effect. End result, I did notice a difference of 40-70KM using fuel enhancers. Btw, fuelly.com, my car engine option is "Model Engine"? |

why need to empty tank? don't have to take risks like that lol... in fuelly.com configure to track mileage based on ODOMETER reading, meaning the bigger number e.g. 86500km reading.
Then just do this: 1. Fill to full let the pump auto stop. 2. Record down odometer reading e.g. 86500 3. Drive as normal, or drive outstation for a trip. 4. When you want to track the mileage, e.g. after a round trip outstation, just pump to full again let the pump auto stop. If possible use the exact same pump/location as #1. 5. Now key into fuelly your current odometer reading, e.g. 87500 and liters pumped, e.g. 10liters. It will calculate and show you your km/l or l/100 depending on your config. You can also calculate manually, in example above it's 10km/liter. No need to resort to driving till tank empty... in fact it's a good idea to refill around 1/4 mark instead of letting it go to low fuel warning. |

Non full tank in fuelly is for when you don't fill to full, e.g. pump RM20 only without letting pump auto stop.
If you think about it, it really doesn't matter at what point you fill - the important thing is you need to start with a full tank and when you refill anytime, it must also be to full tank. If I fill at 250km traveled and it takes in 20.52 liters, that means 12.18km/liter (250/20.52) - at this same rate, if you were to max out the tank, it should give you about 45x12.18 = 548km for a full tank. Unless you're going for a Malaysian record longest distance traveled in 1 full tank in an Iswara, then it really doesn't matter when you refill. You just need to start with a full tank and refill to a full tank, that's all. QUOTE(Quazacolt @ Aug 23 2012, 10:54 AM) the odometer reading is based on an averaged out algorithm/calculation over a longer period (or more accurately, fillings) of time. (which is why there is an option for "non full tank fillings" so if you really want a more accurate reading, it's still best to get a full "1 tank's worth of fuel". granted, that is practically impossible and the hassle of an empty tank is less than desirable. That, and there is a risk/long term damage towards the fuel pump (i probably should have mentioned this in my earlier post, my bad on missing this out) however with a few liters (our car has 45liters dont forget) left in the tank, that should be no problem at all |

I know what you mean about partial fillings causing your calculations off. This is because (I bold the relevant parts):
http://www.fuelly.com/faq/6/partial-fuelups How do I account for partial fuel-ups? If you can't completely fill up to the top when you're at the pump and you want to track the fuel-up in Fuelly, check the box next to This is a partial fuel-up. This will let Fuelly know that you have a partial tank. Once marked, Fuelly won't calculate MPG for that fuel-up or the next. However, your partial fills will contribute to your overall average MPG. Fuelly's calculations rely heavily on you filling your tank completely, but we realize that's not always possible. That's why if using fuelly, it's easiest just to refill to full anytime. E.g for myself I get a bit of rebates if I fill on weekends so I just pump to full each weekend no matter how much petrol left. Even if still more than 1/2 tank. Fuelly tracks it very well. QUOTE(Quazacolt @ Aug 23 2012, 11:36 AM) hmm not sure if its just placebo or maybe the few times i did partial fuel ups waaaay back then throw the calculations way off, or a combination of both. since then having a empty to full 41-43 liters fuel up i tend to get more averaged out readings (which should be accurate in that sense) This post has been edited by poolcarpet: Aug 23 2012, 12:15 PMbut yea from their site, they mainly stresses on having a full tank filled as you said |

The Iswara dashboard meter consists of 3 parts, RPM, Speed/Odometer and Fuel/Temp.
If Odometer only not running, but the speed is ok and the rest all ok, most prob odometer kaput. I think there are some people who can fix it, but I had the same problem and went ahead and changed the odometer + the cable. Original Proton part RM150 for the meter, another RM20-30 for the cable if I remember correctly. Very easy to DIY change, just need to be a bit careful. QUOTE(xavi5567 @ Aug 23 2012, 09:27 PM) |

Did you change/add anything else other than the VS before the foot dyno test?
QUOTE(megadisc @ Aug 24 2012, 10:23 AM) since i do not have any measurement tools i just put my foot to the pedal till the medal main thing i felt was when ipress slightyly ..i can feel power rush . sorry for exaggerating boh leh ..its been 2 years since i sintalled it 10yrs old iswara, dont expect much next project is to find a way to remove the carbon sludge in the engine any dieas ? |

well, my point is, without proper scientific measurement, all these so called effects can be down to perception. if you've believed a certain point (whether it's brighter headlights, colder ac, more power, etc) then you are almost ready to accept and believe it.
my point is, if we were to say these and any other add on helps, we need proper scientific measurement along, e.g. dyno test for power, lux meter (or whatever you use to measure brightness) for light, temperature sensor/timer for AC coolness. otherwise, as humans we tend to perceive things which we want to believe. QUOTE(Quazacolt @ Aug 24 2012, 12:02 PM) 100% agree. however do take note: i can confirm that we have no ECU (carbie mah, only your foot and some cables and vroom vroom lol) in our iswara lol nor do we have any voltage stabilizing components/capacitors/transistors oh and: LOL'd they also got contacted by Ricky Willems, a senior electrical engineering and product design major at Rensselaer Polytechnic Institute, a member of SAE and IEEE. and yeap, good insights overall REGARDLESS. my personal take on VS and grounding cables: VS as the name implies, its a stabilizer, it doesn't magically add voltage to your car (again, no free energy, remember?) if you dont have heavy load such as a 4channel 1.5k watt amp whacking 12" subwoofer and 6.5" mid basses, i personally think you probably don't need it. our engine have no ECU anyways to warrant a stable energy. at most you'll get cooler AC (highly subjective) and brighter headlamps (if your not speeding like mad to need the longer/more stable throw, also no need right? also subjective based on ricky's insights here's the deal for me: - i speed, so having brighter/longer light throws are always welcome to minimize my chances of getting into trouble - colder air cond (which seems the case on previous/current experience on using VS) is definitely appreciated in long afternoon jams *coughserembanhighwaycough* - i have ICE, entry level, but a complete/decent setup no less that said, i personally however do not believe in performance increase, which MAKES SENSE as i don't even have an ECU in my car. Grounding cables simply put, our car's original grounding cables are actually sufficient the problem comes throughout years of corrosion/oxidization, which reduces the effectiveness of your stock grounding this is actually a very straightforward thing in the sense that, it either works, or it doesn't, binary result. when you have your grounding system in proper, electrical systems in your car just works, simple as that. so by having additional (again, all cars already have stock grounding) grounding cables, you're merely RESTORING your car's grounding capabilities. you do not increase performance or anything, it is merely restoring it to what it once was when you bought a new car (so take note, if your car's fairly new, you probably don't need this at all, and yes even on ANY proton cars) one thing to note though: for the love of god don't spend money buying imitation/bad grounding cables. typically aluminum based, and does NOTHING for your car. if you're skeptical, ask the seller if they have voltmeter to PROOF that their grounding cable works. now for my case personally, some interesting info from eric's grounding cables: - previously my car has HKS imitation (thank god it was free, rofl!), when 1 of it lol broke, and i get to see the inside of the cable, i realized immediately how bad it is. thinned as hell, and lol aluminum core what i did not realized, is how bad it is: it does nothing! it has ZERO amperes of electrical load! - stock grounding is taking up ~10-12 amperes of electrical load - eric's cables take up between 10-20 - upon installing his cables, as it already take up majority of the load, the stock grounding drops between 0-2 ampere load. LOL! so yes, get a voltmeter, PROOF that the cables are not just sitting in your engine looking pretty |
