Chips

EndTuning can provide preprogrammed chips for a wide variety of vehicles. Custom software is available on all chips for specific requirements. In most cases, Fueling and Ignition curves are fine tuned, Boost control will be adjusted if fitted, Speed Limiters will be removed, and RPM limiters raised. Adjustment can be made to Idling control for vehicles with alternate camshafts if requested to counteract charge loss from longer overlaps.
Corrections to self-check features will then be applied before programming on a new Eprom. Be aware that digital watermarks, program signing and other anti-counterfeiting systems may be installed, and your eprom chip may cause damage if fitted to a vehicle other than what it was programmed for.
The Chips can be supplied mail order for DIY fitting, with full instructions and precautions, or fully fitted either at a no cost option in Birmingham, or at a moderate charge for other UK locations. To order a chip, simply call or email for more info on what is available, and pricing. If you want to fit the chip yourself, take a look through our Chip Fitting Guide to see what this entails.
