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.

Recommendations for the use of SPI:

Operating system: Win98, WinME, Win2000, WinXP
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 is protected and you have control over the number of tuned cars.
