What does it take to convert from an 0411 LS1 PCM to an E38 controller, and will the stock dash and gauges work?
Here is what the documentation says. Each point links to its source; tables and names vary by computer, operating system and tuning software.
- 0411, 1181, E38, E67, E78, E92; LM7, LS1, LS3, L96, LT1; 1999-2020: The OBD-II connector must be wired into the swap harness: it is needed both for flashing the controller and for later diagnostics. (Chevy Hardcore)
- 0411, 1181, E38, E67, E92; LM7, LS1, LS3, LT1; 1999-2020: Know what programming is inside the controller before the first start: firing an unconfigured swap risks damage, so the baseline tune should be verified before cranking. (LSX Magazine)
- 0411, 1181, E38, E67; LS2, LS3, LS7; 1999-2015: A Gen IV engine cannot be run by a Gen III controller without converting the reluctor wheel and adapting the cam sensor and throttle hardware. (LSX Magazine)
