Maybe a dumb question, but can I take an E67 tune and load it on an E38 ecm?
Application is a new LS3, 495-525hp and 6l80. I've done a few vehicles with the E67 and same engine combo and got them dialed in nice. Now I'm working with the same engine combo but with an E38 ecm. Is it possible to write the calibration tune from 67 onto the 38? Thanks
