What exactly is an Evolution chip?
Interesting question actually, because nowadays in nine out of ten cases you won’t get a chip at all as we will reprogram your management system via its serial port which is normally located on the dashboard, but on older cars we would literally change the EPROM which is the Microchip within your ECU that contains all the maps and information required to make your engine start and run correctly.
So... How do we do it?
All our re-mapping starts with us test driving the car and reading the management with an appropriate scanner to ensure the vehicle is already doing what it should do and is in a healthy state. There is no point tuning a faulty car of course.
If all is well, we will then proceed down one of two different routes, we will either extract a copy of your ecu software via the vehicles on board diagnostic port and transfer it to the PC for recalibration, or we will physically remove the ecu and unsolder the correct chip from within it and then use a programmer to read and save a copy of its contents onto a PC. Generally speaking, on vehicles prior to 1995 we will remove the chip itself, and on vehicles from 1995> present day we will do all the work via the diagnostic port on the vehicle.
After archiving your original file for safekeeping, we will then set to work optimising the contents of the program, carefully tuning parameters such as:
