A friend here has bought a superchip icon from Ebay for his MGF VVC which arrived today. He saw on the web that there were two versions, one for 1.8i and another for 1.8vvc. Upon opening the package he saw that in order to connect it to a vvc he should require two cables which were not in the package, so he thinks this one is for the 1.8i and is asking if he would be allright to fit this to his car.

DO NOT FIT THIS TO THE CAR. If this is one of those "extra 20BHP for £25!" chips from Ebay, all they do is feed more fuel into the injectors with little regard for the long term effects - AVOID  |

Not the eBay cheap'n'cheerful resistor, but thanks for the warning as they should be avoided at all costs. ----------------- ICON Race chip is a piggyback ECU that intercepts the signals from the MEMS, overlays a map and then sends them onto the engine. It also intercepts the returning signals, removes the effects of the map and then sends them back to the MEMS. The map therefore is CRITICAL to the smooth and safe running of the engine and i would never buy one off the shelf with a stock map, this kind of thing really needs setting up on a rolling road with a map that is bespoke to the car. If you suspect the wrong map has been installed then although it probably will run the car, who knows what damage it is doing long term? Pre/post ignition? Over fuelling? Not good. I have also heard some horror stories. I have one sitting in my garage, it has been there since 1997 and won't be fitted to the car any time soon i am that worried about it.  My advice is to take the car to a rolling road that deals with Superchips (if possible) and get them to map it to the car. It's the only way to be sure. |

To echo what Andy said...
Aftermarket 'piggy back' chips ala Superchip really need setting up by a competent operator on a rolling road since what they effectively do is alter the ignition curve and fuel delivery to the motor.
If the wrong map is used then disaster could await your motor!
That said, most come with a base map (usually set to 10 degrees BTDC) which delivers a 'limp home' mode.
The claimed advantages of such chips are, IMHO, overstated. While there are advantages to be gained on turbocharged motors, with normally aspirated engines the performance improvements are far more limited (and not good value for ££).
Basically what the system does is to allow the engine to make better use of higher octane fuels - the F/TF are factory set for 95 RON, so using a chip would allow a map for, say, 99 RON. However, the problem comes when you revert to using lower grade fuel - unless you can 'turn off' the chip, then the ignition map will be too advanced for the octane and detonation will ensue. Given that the F/TF have no Knock Sensor that would retard the ignition during such periods of detonation then you are far more likely to blow your motor up.

superchip say there chip only close down the wide timing band the manufacturer use just in case the county the car is in has 91 ron or less and does not increase fueling
