i have been wondering on which speed chips actually are what they say. dont know much about it except, i know it increases air and fuel mixture. but dont know which one to go with they say gain 20-50 hp any info would be nice. ups and downs ect. thanks.

 

Don't waste your money, save it for a PCM tune.

 

I vote aganist them...ALL of them. Snake oil, man. That's all it is, pure and simple B.S.

 

really? i honestly thought the chips helped...maybe not what they claim but i stil lthought it helped, but my experience was a chip that wasnt in a camaro.

 

The junk *** ones on Ebay don't do anything, they are simply a Radio Shack resistor that has minimal to no effect on performance.

 

so roughly what would a functional "quality" chip cost ?

 

so is everyone saying that buying a new chip for ur car is a bad idea in genral or just to buy one off ebay becuase i have had countless people tell me i should upgrade my chip before i do anyhting. I have a 30th anniversary camaro V8 5.7 L yadayada so i dont know what to do considering i am hearing 2 sides to this product.

 

they arnt refering to having the car chipped. they are refering to the little things on ebay that say "+20HP Instantly" and go for $2-$30. You can get a real chip programed for your vehical for $100-$300 usally which will acully help your car. But these days like z28pete said, just have it tuned and they can hook crap up and do it all with software.

I read somthing off a site recently about these:
"If you are suckered into buying one of these, you'll get a kit containing a resistor that you connect to the positive line of your air intake temperature sensor. The idea is that it fools the ECU into thinking the air charge is colder than it actually is. So why does they claim this works? The claim is that the ECU will be fooled into increasing the fuel in the fuel-air mixture making the engine rev better, and adding 20bhp to the power.
Of course like all these scams, that's not quite the case. First of all, it's the air which would make the engine run better, not the fuel. That's why turbos and superchargers push more air into the cylinders. By running more fuel, you basically run a richer engine which makes the engine run cooler. As well as that, all EFI engines have lambda sensors to measure the actual fuel-air ratio and the ECU takes this reading and adjusts the fueling accordingly. It doesn't simply do it from the intake air temperature. So if you fit one of these devices, this is what happens:
1. The ECU gets a reading from the IAT, and adds more fuel.
2. The Ecu then gets the actual fuel-air ratio info from the lambda sensor, realises it's over fueling and cuts the amount of fuel it puts in.
3. The cycle repeats until the excess fuel totally destroys your expensive catalytic convertor.
4. The ecu will also adjust the igniton timing everytime it gets new info. This means the ignition map is constantly changing which could eventually cause the engine to knock/pink, but will certainly make it run rougher than a tractor."

just remember "A fool and his money are easily parted"

 

My sentiments, exactly. People should learn how an engine works, before trying to modify things.
