SPI 28 ECU Flasher
The memory for software and data has been implemented as a programmable component into ECUs for a long time now.
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 improve 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. It- s possible 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 since no simulation is possible. A stand-alone ECU can be problematic
The SPI is a co-development with the UK 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 affordable.
Depending on the ECU the read out files resp. the tuning files to program have another length than the eprom. Furthermore identification must be put into the tuning file. Both can have the result that the checksum can be corrected only with Win OLS.
Recommendations for the use of SPI:
Operating system: Windows 98, Win ME, Win2000, Win XP
Ports: parallel, serial( adaptor SPI105 doesn't work on all cars )
Coding (SPI200 / SPI230):
With the help of the supplied coding program you are able to encrypt your tuning files and deliver it together with coded customer keys to your retailer. So your know how it- s protected and you have control over the number of tuned cars.
It is normal for antivirus to flag some diagnostic files (.exe etc) as virus or trojan. Always switch off antivirus in your computer before attempting to install any diagnostic software or the software may not install and essential diagnostic files may be corrupted. Do not use downloaded software, or older versions, only use the software supplied with the tool.
