What exactly is an Evolution Chip?
Interesting question actually, because nowadays in nine out of ten cases you won’t actually get performance chips 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. We modify the contents of these EPROM's and the end result are optimised performance chips.
So... How do we do it?
All our re-mapping and ECU tuning 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 performing any ECU tuning or fitting and kind of performance chips to 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 chips 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 chips, 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 ecu parameters such as:
