Looking extract the highest level of performance from your McLaren MP4-12C’s ECU? Alpha Performance now offers a true ECU remapping service that will unleash the potential of your MP4-12C. Unlike piggy-back (plug-n-play modules) that trick the ECU, we reprogram the ECU itself to produce a safe and robust level of performance that will pin you to the back of your seat every time you punch the throttle and let loose the 700+ horsepower on tap!


As seen in the diagram below, power is significantly improved throughout the entire RPM range. You can expect:
+Average gains of 100 horsepower and 105 ft-lbs of TQ throughout the entire RPM range
+Power increases of over 115HP compared to the stock tune between 4600 to 6900 rpm
+Torque increases of 124 ft-lbs compared to the stock tune between 4500 to 5600 rpm
+Alpha tune maximum HP output: 716 HP vs stock tune 629 HP
+Alpha tune maximum TQ output: 601 ft-lbs vs stock tune 476 ft-lbs

This quick upgrade will provide very noticeable results on a light and nimble vehicle like your MP4-12C. Even better, all of this is done with just our Alpha calibration file, no other modifications or special fuels needed!


Your McLaren MP4-12C is equipped with a highly complex BOSCH ECU. This design uses a closed-loop system for air-to-fuel ratios, torque output as well as a number of other outputs. Sensors provide feedback to the ECU in regards to throttle position, ignition timing and boost where they are then balanced using the appropriate parameters programmed into the ECU. In addition, engine performance is mathematically modeled so that the ECU knows how it should be running in case of a sensor failure.

What does this mean?

Unlike our Alpha tune where our engine calibrators adjust the actual parameters in the ECU, a piggy-back module intercepts and sends artificial readings to the ECU. By doing so, there is risk of damaging your engine when relying on the intercepted (cheated) sensor outputs. Because we edit the ECU itself, the commands are true to form without any possibility of confusion.


Just like all vehicles using an Alpha calibration file, your MP4-12C will exhibit smooth, stock-like drivability. The only difference is a dramatic increase in power and acceleration. What’s even better is that you’ll be able to enjoy all this with no detrimental effect to fuel economy at partial throttle or cruising speed.

Below is an engine hp chart comparing an MP4-12C with our tune vs the latest tune from McLaren:

Here is an actual dyno done here in house on our AWD Dynojet Dynamometer of the same car before and after:

Again this isn't a module or a piggy back but a real sustainable ECU tune.

$5999.95 is the cost of the tune which includes free overnight shipping. For more information please email me at [email protected]

Thank you!
