SPI 028 car chip tuning interface
Log into your cars ECU and update the software to increase power by up to 35kW!!!!
Specialists charge over R4000 to re-load and update your ecu. Why not purchase this unit and be able to update your car forever for only R5699.00 You could even undercut the specialists and charge R3000 to re-load and update ecu's for other people
The memory for software and data is implemented as a programmable component into ECUs for a long time now. Ever since these components are erasable even as an assembled part of the ECU more and more vehicle manufacturers chose to provide the possibility to re-load / replace the software and data contents of the respective control unit in addition to the analysis and error detection mechanisms.
By doing so vehicle manufacturers achieve the ability to work knowledge found after the production has started into already delivered cars resp. their ECUs.
With the help of this interface the tuning technician is able to load a modified file into the ECU without the previously unavoidable hassle of mechanical jobs on that very unit.
no need to dismantle the ECU
shorter waiting periods for the customer
the possibility to reverse the software upgrade without any trace e.g. when selling the car
As practical as this is, it's also a tricky business:
not every ECU allows reading out its data via this service interface
one easily can overwrite a tuning file while carrying out an inspection
no simulation possible; therefor only restricted suitability for research purposes
an actual vehicle is essential - stand-alone ECU is problematic
The SPI is a co-development by us and the english company Superchips, who offer their own tuning files with a similar system. But if you need to load your own files serially we can offer you the independent EVC SPI system for reading from and writing to ECUs.
In order to program an ECU one needs a customer key besides the software, an adapter box and the connection cable. When programming the ECU for the first time the customer key is being permanently linked to the respective car's VIN (vehicle identification number). Thus this programming process can be done as often as you want but the next car will need a blank customer key.
Due to this licensing method the further development of other car types is ensured while the basically equipped versions can be kept rather affordable.
Depending on the ECU the read out files resp. the tuning files to program have another length than the eprom. Furthermore an identification must be put into the tuning file. Both can have the result that the checksum can be corrected only with WinOLS.
