Subaru Select Monitor Parameters Under Driving Conditions
Note that these are taken from EJ22s transplanted
into Volkswagen Vanagon/Westfalias; those in other vehicles will most likely
have different values, especially for drag-sensitive parameters such
as engine load. Please email me with any additions at the address below.
Dynamic Values
Here's some graphs of various EJ22 engine parameters during runs
with various running conditions.
- engine warmup
- 0 to 60 to 0, shifting through 3 gears
Static Values
These are some engine parameters for 1990-5 EJ22 engines
under various relatively steady state driving conditions.
