Send it back. Its not a chip. Wanna know what it is? A resistor packaged to look like a chip. You can get the same thing from Radio Shack for $0.39. All it does it mess with the readings obtained by the sensors and forces your car.to make the wrong AFR which gives you a slight feeling of more power, but overall really doesn't do what it advertises and isn't the best for your engine.
guys im not the gunea pig here, there r utube videos of bimmers and also other cars with this brand mod. lol well maybe some1 can send me a pic of their 3.2 l6 engine bay w the iat sensor highlighted... ill b sure 2let u guys know if it was wirth the 75 bones
1. You bought a "mod" with no prior research as to what it really is.
2. This "mod" comes with no instructions.
3. You come here to ask for install help, and you get good information telling you that its a complete waste of money.
4. You ignore advice, and claim a friend's STI was made quicker using this junk "mod".
5. You decide to plow ahead and give it a try.
Honestly, you dont need to know where to hook it up properly, just toss it in the engine bay and that'll give you the same amount of power, w/o really any risk of damaging your motor :thumbup:
You need to read this, go to this website, and try using this search engine next time. And just because it gave an STI 35hp doesnt mean it will do jack for a BMW. The engines are so far apart in design, there just is no comparison. One is an inline 6 NA RWD, the other is an laterally mounted four banger that relies on a turbo and AWD. One is a refined driving machine, the other is a rally car with a half decent interior. BIG difference
