i have a 93 import wrx and was wondering if there are any data loggers or obd code reader that are available. i no there is away to read the check engine light i was just wondering weather there is away to recieve live data from the ecu eg knock counts of labda readings.

 

No such thing as an OBD port in a 93 impreza... and nothing to live read the ecu unless you buy separate devices such as knock link and labda link and things like that...

 

An early Select Monitor should do that, think there are some third party SSM1 emulators around too, altho don't have any detail to hand. As said no generic OBD support on these.

 

this is what you need to read live data from your early ecu, http://www.limitless.co.nz/cables/, there is other methods but this is regarded to be the best.
