I was just wondering if anyone has used one of the computer chips for a 88 5.0 Tbird, and if they had any results from it. Also are the ones i see on ebay for 30 bucks any good for anything??
Thanks
Jeff
the ones on ebay are scams, dont even think about it
for the tbirds, we dont get any aftermarket chips, unless we swap to a stang engine and stang computer
The ones on eBay are nothing but a small resistor designed to trick your engine computer into thinking that the air charge (incoming air) is colder than it really is, thus causing it to run slightly rich. If you see any power gain at all it would probably be in the fractions of horsepower, but you'd also burn a bunch more gas and foul your plugs with carbon.
Oh, and you can buy the resistor at any electronics store for about 5 cents. Here's the chart for normal ACT readings:

As you can see the resistance lowers as the temperature rises. If you unplug your ACT sensor and insert, say, a 58k ohm resistor, you'd trick the computer into thinking the incoming air is around 50 degrees.
Like I said, you can buy this resistor for about a nickel at any auto parts store. Those scammers selling them on eBay for upwards of $5 are, well, scammers. Some of the more elabourate scammers actually put the resistor inside a casing and charge you $30, some simply give you a resistor and sell it for $5. They're all the same thing, just someone out to make a buck off the uninformed:deal: .
ive seen a few guys actually put a FUSE in the case, no resistor, just a blade fuse
