Here's what the advert said:

WORKS ON ALL CARS 1988 ONWARDS.
YOU WILL FEEL THE BIGGEST BOOST ON CARS WITHOUT A TURBO FITTED.


WHY PAY £200 - £500 FOR A CHIP THAT ESSENTIALLY DOES THE SAME THING.


YOU CAN FIT THIS YOURSELF VERY EASILY IN A COUPLE OF MINUTES AND YOU WILL IMMEDIATLY FEEL THE DIFFERENCE !!


This simple, yet effective modification will allow you to boost the power output of your vehicle's engine, without sacrificing reliability or comfort. It consists of a small electronic device that will be inserted between one of your car's sensor and the ECU. This is also know as a 'piggy back' device as it is external to the main processing unit (the ECU). You will feel the gain instantly, no fooling around or expensive tuning necessary. This unit will work with all vehicles equipped with electronic fuel injection. 99% of cars manufactures after 1988 are equipped with electronic fuel injection. Here is how it works:

You have probably heard of performance eprom chips. There chips consist of a stock computer program that has been altered to inject more fuel into the engine under acceleration. Timing curves are commonly also adjusted consequently. These chips can be found to be quite effective, but also pricey as you not only need the chip, but also a socketing kit. You then need to do some soldering on your computer board which can damage it and cause it to malfunction. On the other hand, this 'piggy back' electronic device will alter the fuel and timing curves in a very similar way as the eprom chip would, but without even opening the ECU. How can it do that? By fooling your computer and letting it think that you are sucking air at a different temperature. Your computer will respond with increased power!

FAQs


Q: What is this Device?

A: It is a resistor chip that gives out a constant reading of air temperature to your ECU. (in other words, this is a resistor pure and simple! In fact, this particular 'chip' replaces the existing inlet temperature sensor completely, so there is no compensation for inlet temperature whatsoever... oh dear, dodgy rating heading off the scale here! - Ed)


Q: Will this work with a TURBO KIT?

A: Sorry this will not work with a TURBO KIT.


Q: What is an ECU?

A: An ECU is a computer that manages your engine and keeps it running. It received data from the different sensors on the engine and reacts consequently, adjusting the level of fuel injected in the engine as well as the timing advance.


Q: What is a 'piggy back' device?

A: A piggy back device is a device meant to externally alter one or more signals sent to the ECU. This is a very common thing to do but also very expensive. Most piggy back devices cost a few hundred dollars.


Q: Will this fit on my vehicle?

A: If your vehicle is equipped with electronic fuel injection, it will. 99% of cars manufactured after in or after 1988 are equipped with a fuel injection. It will however not work on turbocharged vehicles. (note that your ECU will also need an inlet temperature sensor - not all versions of EFI use this sensor... - Ed)


Q: Will my car accelerate faster with this electronic device?

A: Yes! This is the whole point! It has been dyno proven that this device will add up to 20 HP to your vehicle! (would love to see evidence of these fantastic dyno results on an independent rolling road! Unless the sensor has failed in some way, there is no chance of seeing a significant performance gain of this magnitude! - Ed)

Q: Will this device damage my car?

A: Absolutely not. Since the altered signal will always stay within the manufacturer's specifications, there is no way for your engine to get damaged in any way. (the damage through increased wear due to bore wash will take some while to manifest - and will be dependent on the degree of over-fuelling. This will vary from car to car, as not all temperature senders have the same calibration - so fitting a 'one resistor fits all' solution could easily send the sensor values out of the manufacturer's range - Ed)

Q: How hard is it to install this device?

A: Installation is very easy! Detailed instructions are included with every product as well as all necessary hardware.


Q: Do I need any special skills or tools?

A: No special skills are required. A simple pair of strong pliers will be necessary for the install.


Q: If it breaks, will I get a replacement?

A: All units are %100 guaranteed not to be DOA. If your unit ever happen to malfunction, it will be replaced at no extra cost.
