SPI 28 ECU Chip Tuning Programmer

SPI 28 Description

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 28

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
