So called mod chip

Hi all.

Just been on ebay and spotted this:

ADD UP TO 20BHP +++

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

What is this Device?

IT is a resistor chip that gives out a constant reading of air temperature to your ECU.

Will this work with a TURBO KIT?

Sorry this will not work with a TURBO KIT.

What is an ECU?

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.

What is a 'piggy back' device?

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

Will this fit on my vehicle?

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.

Will my car accelerate faster with this electronic device?

Yes! This is the whole point! It has been dyno proven that this device will add up to 20 HP to your vehicle!

Will this device damage my car?

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.

How hard is it to install this device?

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

Do I need any special skills or tools?

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

Has any body got any experience of it either good or bad please? It's priced at £4.99 + P&P which seems too good to be true. Sorry about the length of the post!

Don't touch it...not even with mine grin.gif

These things are a con, yes I agree they will probably raise the power slightly, but in no way are they anything like a chip which is changing and adpating many more items to gain the power increases. Do they offer warranty? No. Does a chip tuner offer warranty? yes....I'll say no more.

If it was this simple and realiable would tuners not be doing the same?

The resistor basically tells your car that the induction temperature of the air is much cooler than it actaully is this then tricks the ECU to adding more fuel and adjusting timing, this more fuel cannot all possibly be burnt 100% of the time especially not in summer..... SLEEP5.GIF sorry, but there's much more I could say about simply adding a resistor to the ECU but I don't want to bore you, needless to say I wouldn't recommend it.

Fully agree with Gambba, leave it well alone indeed! NONO3.GIF

If you want a good job it's gonna cost you more, but you get what you pay for. There is no - good - way to do this without a proper remap.

This cheap 'switch' type thingy just bypasses your motor management in a very crude way, which is NOT a good thing for rather obvious reasons. Plus your fuel economy is down the drain, and it could lead to costly repairs...

Better save up for a good tuning, or leave it alone. wink.gif

Ok thanks V much for the advice, I'll leave it well alone. Just to be cheeky then, and while you're on a roll, any ideas on how I can improve it properly without too much outlay? I own a Golf 2.0 y reg 2001.

If its a normally aspirated engine I'd suggest a bigger exhaust, replacement ait intake & filter. Uprated plugs can help.

Apart from this more costly options include a new Cam shaft.

Nitrous can be a cheap option, but don't do a "homebrew" speak to someone like AmD!
