can the 99 saturn be tuned?
can the 99 saturn be tuned?
if it has the GM L4Big ecu then you might be able to. The oldest visible tune from saturn is a 2000 L series with L4Big ecu.
Earlier then that was the chev cavalier which also had the L4Big ecu.
if you dont have the software i suggest finding someone who can perform a quick ecu connection so a log file can be generated. from the log file you can get ecu model, os, hardware information which can be emailed to hpt tech for support verification.
