Do these 20+BHP chips on ebay actually work or just crap....

Has anyone tried them? :confused:

Interesting if they do as big a cost saver on ECU though somehow bet they will just screw things up

Beware - they are almost misrepresenting a cheap i.e pennies, gold tolerance resistor as a silicon chip with implied some form of processing. It only distorts temp sensor readings nothing else.

 

The way this "device" is supposed to work is by fooling the ecu into thinking the engine is cold and therefore making it run richer than it should when hot. Some simple cars might gain bhp at the expense of bad emmissions.

 

Anybody daft enough to fit this in a TT zed would I think keep it permanently in safety boost and running too rich because the zed ecu doesnt let you play until the engine is warm enough. Not only would you get negative performance gain but you burn more fuel too.

 

Just pull off the temp sensor connector for a similar effect! Its free and also pointless

 

Verdict - crap

Will this fit on my vehicle?

 

If your vehicle is equipped with electronic fuel injection, it will. 99% of cars manufactured after in or after 1988 are equipped with a fuel injection. It will however not work on turbocharged vehicles.

If they do anything on a Z, I'd be very surprised.

 

For a start;

 

By fooling your computer and letting it think that you are sucking air at a different temperature

 

The Z has no ambient or intake air temperature sensor (largely because it uses a hotwire MAF).

 

By tricking the computer, we are able to make the reading of the computer shift to the right, which will make it think it is under heavier load and increase the power

 

'The reading of the computer shift to the right'. Uh huh. Indeedy.. I can't even work out what they mean by that! Ok, you could change the MAF signals, but just injecting more fuel isn't going to give you more HP unless you're putting more air in too.

 

And the nail in the coffin is (for TT owners, anyway);

 

It will however not work on turbocharged vehicles.

[edit] Darnit, beaten to it.. by loads of people.. :)

Cheers fellas

 

thought as much, CRAP
