Saved us from ordering new ECM which would take weeks.
Customer brought in a Sea-Doo GTX that stopped starting after software update attempt at home. ECU was not responding through standard diagnostic procedure.
After selecting correct stock firmware from database and stabilizing voltage, flashing completed successfully. Engine started normally and unit went back on the water same day.

Installed tuning firmware on customer Jetski.
Vehicle feels more responsive now. Will monitor long term but initial results are positive.
