Nope!

You can only retrieve very basic diagnostics results from a 3-pin port (found in the engine bay loom) in the form of pulses (either using an LED or a code-reader which just translates the pulses) and if you want to do any form of tuning/mapping, it typically has to be done in the form of a chip/plug-in module inserted into the J3 port (at the other end of the ECU to the EEC-IV connector). Unlike with VAG cars, there's nothing like VAGCOM available for us to use for diagnostics or, for example, Revo for user-friendly/safe tuning, so you really have to take your chances with a Superchip (which isn't really worth the money) or have your car properly mapped by someone who can tailor a chip for your ECU - although you would see very little benefit from such a service with a 1.6 Si
