Stand-alone laptop (SAC) systems absolutely replace the factory ECU, assuming complete manage of the engine. Re-mapping the engine can be accomplished by plugging a special cable into the OBD-II port, and from there the maps can be study out of the ECU, modified as needed and then ‘flashed’ back in. Re-flashing is an solution for numerous cars created from about the year 2000 onwards, but not each and every car in production is supported. PREracing can refuse any tune or cease tuning a car or truck at any point if they feel there is a condition which is unsafe for the automobile, shop equipment, or any person.
Do also keep alert if the car has a mileage that looks suspiciously low – there is a possibility that it has possibly been adjusted! Installing a stand-alone engine management system can simply be simplified with the existence of a plug-in harness. To benchmark, an typical automobile clocks roughly about 12,000 kilometres per year, or 1,000 kilometres per month. Undertaking all this really should only take you a couple of minutes, and it’s a excellent beginning point for any car or truck you check out. The AEM EMS is very hard to tune though since it is a extremely complicated method and it relatively new.
There are plenty of alternatives for tuning an engine, but broadly speaking they can be broken down into re-flashing the factory ECU (engine control unit or electronic manage unit), or fitting a standalone engine management system, and I’ll explain what those terms imply now. Clamp marks on the frame rail (under the vehicle) would indicate that the car or truck has been on frame machines – which would suggest that it has been in a severe accident. Generally, stand-alone engine-management systems offer you larger-resolution fuel and ignition maps …Read More
