Thread: What is this? Performance speed chip on ebay. Look!

eBay Motors: PERFORMANCE SPEED CHIP PONTIAC GRAND PRIX SE GT GTP (item 190226973276 end time Jun-07-08 19:33:21 PDT)

Its some resistor. Doesnt really say the purpose of it. What is this all about?

it's junk and can hurt your engine. It tells the PCM its colder then it really is outside.

Just as Vinnie said it spoofs the PCM and causes it to add timing. This is also how the Happy Knob works, although it's adjustable and people with tuners will adust the IAT versus Spark table to work with the adjustable selector.

if its to go to be true its a joke hahaha and i no what ur talking about on ebay all those stupid chips people sell for like what 10 bucks lol

you can just unplug your IAT and get it to do that... correct me if I'm wrong but by unplugging it, it will read at 30 degrees... at least thats what it did on my SHO...

Unplugging reads like -32*

i gotta idea lets all leave are valves and stuff alone and be happy it runs haha

its just a normal 1000ohm resistor......
