has anyone here ever heard of ,or used a so called piggy back ecu chip,i believe u can use these to fool engine sensors into thinking the engine is colder ,and increase the fueling.not too sure about this.anyhow i have one and wanted to find out how to connect it or even whether i should bother!appreciate any help as i searched and couldnt find anything.

 

If you're talking about one of those eBay "chips" that plugs into the IAT sensor, they're completely useless and a waste of money.

 

i didnt get it on ebay a ,but i think that could be it,it does plug into a sensor as u said.so u rekon its crap?

Yes, unfortunately it is. Sell it or throw it away.
