The only reason I ask is because my buddy has one on his Qvale and says he likes the gains it provided. Improved mileage and throttle response, as well as it feels like it has more power although not dyno proven.
my experience with "chips" in generaly is, better throttle response, lower operting temperature ( Fans are turned on earler), harder shifts, very little hp gains--the ads always say 40hp or thereabouts--last car i had (99TA WS6) got 10 hp on a dyno--- my advice, dont do it for the HP gains alone!!
Lol, you got 10hp on your trans am by plugging a two wire resistor in?
Lets ignore the homebrew qualities (hot glue gun, what looks like speaker wire, lack of IC socket, lack of wire strain relief, moderately-bad soldering job) for a moment. Note there are only 2 wires total, the ones that connect to a sensor on your car. Now lets look at the pins the connect to on the IC. (Note: IC = Integrated Circuit, aka chip) Notice only the 2 on the end are connected.
Now lets take a look at how the most basic IC works. At minimum, 4 things are required:
1. Positive power (Vcc)
2. Negative power or ground
Have you noticed that there's only 2 pins total connected on the chip? Ah-ha! Busted. That's right - the chip in this module is not even powered up! Almost all DIP IC's use pins on opposite diagonal corners for Vcc and Gnd. In this case, it is a 20 pin DIP IC, so pins 10 and 20 should be Gnd and Vcc, respectively. (and most IC's that don't follow this scheme would use pins opposite each other in the center) See this for reference:
IC power supply pin - Wikipedia, the free encyclopedia
Additionally, IC's don't like having 'noisy' power that would be typically found in a car. Anything legit would have a basic power supply or regulator to supply the IC with clean, stable power.
So what is actually happening in this example? The scam artist probably grabbed some random surplus chips (such as some common TTL 7400 series, which go for under $1) and probed various pins with a multi-tester in resistance mode. An unpowered IC will show resistance between certain pins. This is likely the case here, although there's no proof that the maker even bothered to check that the resistance is desirable for use as "traditional" IAT bypass.
I have an electronics background (Electronics Technology degree) and can safely say that whoever makes this chip does not.
