Rennsport Systems Performance
Software
- Revised 4-05-07 -
Rennsport Systems offers GIAC
performance chips for all Porsches built from 1984-onward. Performance
enhancing software requires the use of 92 octane (pump) or better. We also
make custom racing chips for racing gasoline applications that allow the
maximum HP available from software.
The '96-'98 OBDII 993's are
soldered in and the DME must be be sent to Rennsport Systems to have the
new software installed.
997, 996, Boxster, Cayman and all
996-997 TT ECU’s are flashed. The
ECU can be sent in or the car driven to Rennsport Systems for this to be
done while you wait.
96 993's must use a
97-98 DME. The 96' ones are not chippable if your DME is: 0.261.204.008 or 0.261.204.378
These DME's are specific to your car since the anti-theft
immobilser is programmed into the Motronic Brain except for the 996 cars.
We are able to re-program
the all 996’s. all 997’s 993, 993 Twin-Turbo, 996 Twin-Turbo,
Boxsters, and Caymans. Please

******* Warranty Questions & Issues*******
One of the most frequent subjects that is brought up when talking
about chipping a car are warranty concerns. Many people wish to know if
installing a chip will void or affect the warranty. This is a very
legitimate question and the last word on this will decided by the Manufacturer
and Dealer.
Now,.......you have very specific rights granted by Federal
Antitrust laws and the Magnuson-Moss Warranty Act that you must be aware of
to keep from being "stonewalled" by a Dealer or Manufacturer.
Under Federal Antitrust Laws, the use of parts or accessories that
were not purchased from and installed by the Dealer do not affect the
vehicle's warranty. Manufacturer's and their authorized representatives,
may not condition a warranty on the use of their own parts or service,
unless the parts or service are provided free of charge. Also, they may not
refuse to honor a warranty unless they can show that an aftermarket part or
accessory is the cause of a particular malfunction otherwise covered by the
warranty.
In other words, warranty coverage cannot be denied simply because
such parts are present on the vehicle or have been used. The warranty
coverage can be denied only if the aftermarket parts caused the malfunction
or damage for which warranty coverage is sought. Normally, these issues boil
down to facts and technical opinions, rather than interpretations of the
law.
Any denials of warranty should be gotten in writing from the
Dealer. The Dealer must describe both the failure and how they believe the
aftermarket part is responsible.
