The McLaren 12C ECU flash is just one upgrade that takes this 3.8L twin turbo supercar to a whole new level. Having ripped the 1/2 mile to 168mph in our 12C, we at Vivid Racing love to prove our product and provide customers with the same remarkable experience. This particular ECU upgrade was done for a McLarenLife forum member who opted to give his silver 12C a little extra boost. To perform the McLaren ECU upgrade, the ECU must be bench flashed, which requires it to be mailed in. The turnaround time is just one day. Once we received the ECU and completed it, the customer was able to then do some of his own testing which he posted kindly on McLarenLife.com here.

“I just sent my 12C ECU to VR last Monday and got it back on Wednesday. Austin was very helpful walking me through the whole process and gave me the Mclarenlife member discount. Subjectively the car feels much faster with improved drivability and well worth every dollar. I strongly recommend this tune to anybody out of warranty. I have run some Vbox sport acceleration times pre and post tune which are slower than expected since I had my original 3 year old Pirelli P-Zero tires on the car running in cold weather. Pre tune runs were at 50F and post tune runs at 45F. Car lost some traction in 1st and 2nd gear pre tune and 1st, 2nd and 3rd gear post tune.
