    Rossion Q1 ECU Tuning

    We were shipped a Rossion for TLC. The owner asked us to check over the tune since it was updated (not by us).

    We decided to datalog and look over the drivability portion the owner complained about.
    Many tuners don't understand the fundamentals and this tune was no different-
    Over-timed for cruising speeds which is BAD for an engine and drivability-

    The final numbers were surprising as it makes less HP than any other Rossion we've tested with an updated calibration-

    The blue graph is a bone stock Rossion q1, the other is an "updated" calibration form the aftermarket-

    The Rossion Q1 updates are generally the MAF, ignition, ignition harness, boost control and valve train, in that order. I'll download one of our tuned Rossion for comparison tomorrow.
