Ecu tuning

[George_bushmechanics]

Hello just wondering with the 03 vy commodores if I can flash tune them through the obd2 port or do I have to tune the ecu directly?
Haven’t found anything online?!

Yes you can. But ECU needs to be set up for it first.

Check out the PCM Hacking forum, they have all the info/gear required to tune these.

vy v6 will be memcal tuning, the LS1 was first with obd tuning and its obd1 i think, the obd2 was in VE onward

VX/VY V6 ecotec have flash memory PCM's (no memcal) and can be tuned via the OBD2 port but generally it's best to do a bench tune first up as they are easy to brick. Once a complete new updated tune is uploaded then you can live tune where you only update the calibration portion of the tune.

Only the VX/VY's with L67 motors continued on with the Memcal based PCM's.
