  1. Well i would like to try it, in a bmw 325i i had i bought a chip from dinan engineering they claimed an 18bhp increase i got my car strapped in a dyno and it actually gave me 15bhp, thats why iam looking if someone here has tested this.

    This isn't a chip. It is a potentiometer. It isn't worded correctly. IATs work solely on resistance. What this does is allow you to change the resistance.

    I suspected you would still want to try it either way, (an observation not a criticism) and there is no doubt in my mind it will change the performance in some way. That's why I suggested buy a pot from eBay. Same thing. Ask tuning wizard for a photo of the inside. You don't need to see values of components as its variable.

    You still have to manually set it yourself so for the case of a quid, why not try one first? It just makes the engine think its cooler than it is when turned up so the fuel ratio is richer, and when turned down makes it leaner. (Hence the alleged mpg and performance - both aren't at the same time - its one or the other). That's the theory.

    In reality by the time the ECU reads the false air temp reading, the other sensors will be advising there's too much fuel in the exhaust gasses and return the fuelling to normal, or at worst, throw up an engine management light if you have the adjustment to far. You will get small bursts - very small. Not noticeable in driving but specialist equipment can detect it so therefore they aren't lying though it could be argued they are mis-selling. As I say, the car will definitely feel different as this is going on because of the resistance change.

    Thanks for explaining, maybe not worth it.
