Cheat Ecu to Save Fuel....

[huakenny]

anyone heard about COSM-II? or EFIE? both gadjet also to cheat O2 sensor voltage to ecu.

But if someone really want to build COSM-II, visit COSM-II - AN ALTERNATIVE TO EFIE :: Fotopic.Net

But they are invented to use with HHO,hydrogen on demand. Lean petrol a bit in close loop and simultaneously add hydrogen. Im still testing it, cant make any result yet.

it uses to lean the mixture, not so suggested. hot climate like malaysia + lean mixture = knocking....

but if u installed hydrogen generator + this kind of map enhancer...u will saves alots as ur car is running lean edi...but u bear the risks

btw,i have try this method on my auto accord last month.yup,it can save a bit,but my car feel like underpower.now i take it out oredi.one my frien use this method on his wira and he combine with his own diy hho generator.the result ha said can save around 50% and more of fuel consumption....plus a bit increase in pickup n power coz he using 2 tank of hho generator to generate more hidrogen...i dont know how to explain elaborately coz i not specialist in hho technology.but it function same like dr.halim product that was official launched by paklah couple of months ago..

can i cure the knocking with water injection?

can i cure the knocking with water injection?

this u hv ot ask drexchan edi lo...he dealing wit this kit.im not sure

weq6356,

Try on your car. You have my support. I will cheer for you too!!

Anyway, running too lean, your car piston may risk burning a hole la....

Prefer not to run lea for those hi rev engine

you have to understand that the ECU of a typical modern fuel injection engine runs in two modes. Close Loop & Open Loop.
While in close loop (typically during idling or during crusing with throttle below 60%) the ecu will get the O2 sensor reading and adjust fuelling accordingly to the target of 14.7 air fuel ratio. So... no matter what fuel saving method or device you are using, the ecu will still try it's best to get 14.7 air fuel ratio in close loop. So, if you cheat or disable the stock o2 sensor, the ECU will not be able to get to the right fuel ratio.. bad for mileage and bad for the environment, or even worse you will lean your mixture so much that you eventually kill your engine. different case if you are using a full standalone management or a piggyback which can bypass the stock ECU close loop operations.

Open loop is altogether a different story, as you are accelerating at 80%-100% throttle, the ECU no longer reads from the stock 02 sensor to adjust fuel, but instead uses the ECU factory preprogrammed fuel & ignition map. that is when piggyback fuel controller comes in handy. Otherwise, change your bad driving habits, have your tyre properly inflated, and make sure your engine is in tuned. you will save more petrol that you can imagine.

can i cure the knocking with water injection?

Yes. But only if this is the last choice.

Water injection is not to be used as a solution for a knocking problem. It's to be used as a way to prevent knocking with aggressive ignition timing setting, for performance upgrade purpose.

I hope you get me..

Using water injection to cure knocking is a very "misleaded" way of modding.. plus the water injection kit is kinda expensive thus eclipse the initial intention of saving money oledi, might as well use the money to buy petrol..

After reading through the article (and the posts here). I realize that many has been misleaded by the "booming" information regarding to "oxygen sensor cheating".

if i adjust the throttle body screw of my car (perdana v6 using ngv mixer) to take in more air, any effects to my engine? thx.. :)

stop discussion about the dirty tricks that sometime work but most of the time don't work.

First, start with a proper overhauling (if the engine is aged), then keep the condition tip-top.

There are several otherways to keep the FC low but please face the reality that every engine has it's own FC ceiling.
