Without going into the merits of whether they actually work or don't - as I know there are conflicting views on the subject I will attempt a simple explanation of their purpose.
The standard ignition/air/fuel mapping on most factory vehicles is going to be a compromise between performance, economy and variable fuel quality. The modified chips will generally be slanted more towards performance than economy with agressive air/fuel/spark maps that also assume relatively good quality fuels.
In short, therefore, they aim to produce closer to optimum air/fuel ratios across the rev range in conjunction with more advanced timing settings.
As a general comment this is not harmful (whether it works or not) on vehicles with knock sensors but can potentially lead to detonation on those vehicles which don't - especially if fuel is not up to its stated octane rating.
Quiet simply Errrr Yes & No
If you buy a "Chip" straight off the shelf & slap it into a Stock 6 or 8 ... chances are you wont get squat out of it, maybe just abit more Fuel consumption.
I have seen dyno charts where the engine in question has been modified ie exhaust intake etc.... And it has picked up afair few more kw from a "Chip".
Personally I run a Chiptorque Module. this is the 3rd chip I have installed & It took just over 6mths before a "Technician" from chiptorque came over to WA & programmed mine & afew others in REALTIME ie on a dyno & the street. Yes Im pretty happy with the end result considering the first chip set me back $590 whilst the second & third were on exchange @ $230 & the cost of the tuning $300... If they cant guarantee to do it on a dyno dont waste your $$$ get a Unichip or better still see XR9 Ute for one of his little toys....

OK, so if you in theory you had a car, say a *5.0 VN Commodore* that already had a chip (brand unknown) and had unknown engine mods and then you stroked the motor to around 327/331 this would make the chip useless, unless you can get it real time programmed on a Dyno?
You know, somebody actually complimented me on my driving today. They left a little note on the windscreen. It said, 'Parking Fine.'So that was nice.
Hey u guys have heard of power chip, now from what i have read their chips are non programable, and can not be modified on a dyno like a unichip. But can they reprogram it to ur car, i got my hands on a power chip gold and was wondering if they can at least change it to be model specific. if that makes any sense.
I think you'll find if its already bought & fitted is already "Model Specific".
Ie you wouldnt be able to fit one from an ELXR8 EEC5 to an EBXR8 EEC4.
I do know however that if the trans were the same & the eec the same ie eec4 to eec4 they do fit as a friend of mine tried it out on his modified Ford.
Once the chip Module itself is "Burnt" it can no longer be changed by re-programming, a new module is needed. This applies to powerchip chiptorque etc. the modules are called "Eprom's"
Holden to name 1 is able to prog & reprogram "Eproms"
AS with Falchoon's "Q" a new program would be needed to suit the new engine's capacity/perameters or with the way Kalmakers software works if it is a "Holden" Eprom its simply a case of re-programming which can be done in realtime
IE thats why they used holden gear etc on that Sony Scorcher they did sometime ago.

mmm ok, well hows this, i took a chip off a cfi manual, and was curious to see if it worked in my car.. auto mpfi, went in but no idea if made any difference. in my mind i assumed the car should not run or start but it did. That why i was asking, and eproms can be reburnt cant they? Is there any way to find out if the EECIV has taken the chip or not?
