	Upgrade ME7.5 to LSU 4.9? « on: February 02, 2026, 03:36:12 AM »

Is someone tried to upgrade ME7.5 to LSU 4.9? C125 IC can control any LSU4.X sensor, and new ME 7.1.1. have LSU 4.9
So what is difference software or hardware upgrade, or both?

Just rewired the plug? ECU plug or LSU plug?
What about Rcal in this case?
