M-Engineering has base ECU calibrations supporting both the GT3 and the GT3 Touring, so one product covers either body.\u003c\/p\u003e\n\u003cp\u003eInstallation is a bench procedure. The ECU is removed and sent to M-Engineering HQ, where it is flashed and returned; typical turnaround is about 24 hours after it arrives. These cars use the newer locked MG1 ECU, which M-Engineering says needs a longer workflow to unlock and flash, so plan for that extra downtime.\u003c\/p\u003e\n\u003cp\u003eOn-The-Fly Live Map Switching carries maps for ACN91 (Arizona, California and Nevada 91), 91 octane, 93 octane and 100 octane, with slot 5 reserved for engine safety. Detonation Defense watches for knock: when knock events pass a set threshold, the car is moved into map slot 5 within 20 milliseconds and held there for about 10 seconds. Stage 1 is written for stock headers and a stock exhaust, where an aftermarket muffler is fine; Stage 2 is for aftermarket headers and exhaust.\u003c\/p\u003e\n\u003ch3\u003eKey specs\u003c\/h3\u003e\u003ctable style=\"border-collapse:collapse;width:100%;margin:12px 0\"\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth style=\"background:#03589c;color:#ffffff;padding:8px;text-align:left;border:1px solid #03589c;width:32%\"\u003eInstall method\u003c\/th\u003e\n\u003ctd style=\"background:#e8f4f8;padding:8px;border:1px solid #c9dfe8\"\u003eBench flash.
