I just added the Torque Converter Clutch 3rd and 4th gear lock/unlock constants to the 1227730_8d.ecu, called it 1227730_8dm.ecu (m for modified) and sent it to Mark Mansur. I don't have a website but if Mark likes it maybe he will make it available on his gmecmedit site for everyone. I am changing over to speed density and wanted an easy way to modify those constants. Small contribution but maybe someone will get some use out of it.
