Hey guys,

Trying to get some advise on Performance Chip Modules. I have done some nice mods to look good but want to do some perfeormace mods now but kinda wanna not spend too much. I have been seeing these online and I was wondering if they are worth while.

And if anyone knows of some cheap mods or free let me know.

 

get one! better yet get two! the more the merrier! 25whp each

 

Not sure if that was a serious recomendation

 

i so hope you're not referring to the 500hp ebay resistor chip mods :/

 

I would assume those didnt work to well, I saw others online thu and was wondering if any are good and worth it?

 

No

 

i concur with them^^^

 

thx appreciate that

 

its a scam bud

 

If i tape two of the chips together do i get twice the performance ?

 

only one way to get real power snail or go home

 

wow

 

the toyota ECU are totally locked down and have never been cracked into yet so basically know plug in module or chip will do anything the only way you can get power from a ECU mod would be to get a hole new like AEM control module

 

first off, search. you wouldve found plenty of threads that answered your question.

but ill answer it anyways. no
the ebay chips are just resistors which "trick" your ECU.
However the ECU is smarter and will adjust within a couple days, and youll be right back where you started.

"The "Mod Chips" being sold on ebay as a performace and or economy enhancement for your vehicle are not a performance enhancement in any way and will infact cause your car to run rich and waste fuel. I will explain - the sellers say the resistor or mod chips should be connected in the IAT or Air Temperaute Sensor circuit. Effectively this changes the signal level output from the sensor indicating to the Engine Control Unit (ECU) that the Air is Colder. Cold air is more dense and therefore has more oxygen so the ECU thinks that the air is colder and squirts more fuel in to burn the extra oxygen. I think we will all agree that in order to get a flamable mix you need three things, Air, Fuel and a spark. The problem with this modification is that the Resistor Chip is giving a false reading to the ECU tricking it into thinking the air is colder, in fact it is not. The ECU thinks it is colder though and squirts more fuel in to burn the increased amount of oxygen. But there is NOT an increased amount of oxygen, the ECU has been tricked, so the extra fuel cannot be burnt because the Oxygen needed to burn the extra fuel is not there.
Car manufacturers spend thousands, no millions of dollars developing efficient engines, if a 1 pence resistor (sold for in excess of £10 on ebay) can really provide the benfits claimed in auctions then they would install it from new, they do not because it is not a performance enhancement and it does NOT give you better economy. If you want better performance then you have to sacrifice economy, you have to REMAP your ECU, change ignition points, increase the air flow, get a turbo or a supercharger, maybe a performace filter. An Air filter and new Exhaust are probably the cheapest/easiest performance enhancement you can make, but even this will only give you about 5 - 10 BHP, for an investment of £400 - over a £1000. Yes, I am afraid nothing comes free in this word"
