sounds logical to me... but got the ask everyone since some of you are more experienced...

by the way they are off ebay...hahaha and they are onli $19

"Have you ever noticed that your car is quicker when it is cold outside and wondered why it could not always be that quick? Well this module once fitted sends a signal to the ECU just like it does when it is cold, then the ECU slightly adjusts the air/fuel mixture which boosts your cars power, it is very simple! The best thing is economy is not increased and can be improved with the fitment of this module!"

Yeah that sounds a lot like a scam to me. A module? From the description it seems it just makes the car run rich all the time? How is this going to increase power?

done to death on these forums if its what i'm thinking of... its not a module, its just a resistor, and will just **** up the fuel mixture etc...

nothing is worth it at $20 for a performance mod...

Scam, may damage your engine.

And can you really tell the difference on a cold morning? I can't.

neither can i.

Edit: then again i let her warm up before driving of down the street. just a habbit cos dads and bros cars are turbo charged.

erm... from what i understand and feel, there is definately a difference when the air is cold... thats why we do CAI cold air intake...BUT... how a chip makes a car "feel" that its taking in cold air is the problem i and puzzled about

been covered MANY timess.

have you ever noticed when the car's cold it idles higher than when it's hot?

that's because when the engine is cold the ECU adjusts the revs to heat the engine up quicker. the only thing that this module does is fool the ECU into thinking that the engine is always cold, thus making it adjust the revs so that it revs higher. it'll increase furl consumption mate.not decrease it.

P.S- It's not telling the ECU that it's taking in cold air, it's telling the ECU that the engine is cold, so it'll lift the revs.

the reason that your car may feel quicker when it's cold is that when you cool a gas it becomes denser. For example, air at 20 degrees has a higher weight by volume than air at 30 deg. Meaning the air the engine is drawing in at 20 degrees contains more oxygen by volume. Oxygen + Fuel + Ignition = Boom! More Oxygen + Fuel + Ignition = Bigger Boom!

So basically you could get the same effect by dumping the thermostat in a container of ice. That'll tell the ECU it's running cold, for sure. lol

No point with these cheap eBay enhancements I find, they most always don't work or have a drawback. Then there's the complete 100% scams... Vortex Valve anyone? :P

Someone who is into electronics can give you better, more accurate explanation.
Anyway, intake air temperature sensor is variable resistor. It has a resistance of 3555 ohms at 20 degrees Celsius and just 475 ohms at 70 degrees.
Output of air temperature sensor is frequently used by the ECU to determine the final ignition timing.
Output of coolant temperature sensor is used to adjust air/fuel ratio.
Your $19 "module" is I believe potentiometer (pot) which you can use to change (artificially) resistance of the sensor so your ECU will "think" that air or coolant temperature is lower and it will adjust A/F ratio or ignition timing.
I understand it can be useful if done by someone who has knowledge about electronics and on some types of Airflow meters or MAP sensors. It also has to be monitored by an A/F ratio meter.
Average car owner like I and you are more likely to cause damage to the engine or to worsen fuel consumption by doing this sort of mod.
If magna has Airflow meter that have a variable frequency output you can't use it.

you can have the same affect by unplugging your water temp sensor.

Just talk to Sports... He has done it on his car. Its a load of crap that i would never touch

Thats for sure lol
