Porsche Boxster ECU remapping
65 files available
About remapping
The Porsche Boxster accounts for 65 files in our catalogue, with a split across generations: the turbocharged 2.0T and 2.5T flat-fours of current cars and the naturally aspirated 2.5, 2.7 and 4.0 flat-sixes of earlier and special versions.
Stage 1 makes up 32 files against 23 Stage 2 — a very high second-level proportion. The turbocharged units offer clearly more headroom. The ECUs include the Porsche SDI9, SDI21, SDI21X and SDI211, plus ME7.8 on earlier cars.

Which Boxster generation gains most?
The turbocharged 2.0T and 2.5T of current cars, clearly. Boost pressure gives far more to work with than a naturally aspirated flat-six.
Is a remap worthwhile on a naturally aspirated Boxster?
Gains are modest in figures and felt mainly in response and the upper rev range. It is worth being realistic about expectations.
Is the work reversible?
Yes. We always keep the original ECU file, which matters particularly on a car in this segment.
