I have done an GMPP LS3 with MPP Controller swap into an early Camaro and am trying to configure the tach output. However the CAL/OS, 12607096/19211212, doesn't have the Tach parameters. Is there a way to add these to the Cal or utilize another Cal and flash the PCM?
Attached is the Cal file I pulled from the PCM (Note: There were some incorrect checksums which I have updated in this file however have not yet flashed to the PCM)Loco_E67_Read_Flash_Update_Checksum_0001.tun
