ECU location and installation
Stock ECU is located behind right fender.
1.Disconnect battery from vehicle.
2.Remove right fender.
3.Remove and disconnect stock ECU from vehicle harness.
4.Remove old ECU brackets.
5.Install and secure the MaxxECU PRO unit with included screws.
6.Install MaxxECU PRO adapter harness.
7.Route the included MaxxECU MAP sensor hose to the intake manifold and connect into the MaxxECU (for boosted applications)
8.Optionally install a intake air temperature sensor (IAT) which is recommended (especially on boosted applications) and connect to MaxxECU.
ECU location on the Corvette C6.
Remove the wheelhouse liner/mudguard, separated into two parts, remove them both.
Detach the fender from the front spoiler.
Remove the two most right screws that keeps the front spoiler in place in the front, so you are able to gently bend the front to access the hidden fender screw.
Gently move the front spoiler in the forward direction to access the hidden fender screw and remove it.
Remove all fender screws.
Somewhere here behind the stock ECU is another screw that holds the fender, please remove this one also.
Remove the 2 ECU connectors (red arrows)
Note: Please do not pay attention to the red/black cable (blue arrow) in this picture, it is just a poor side indicator job...
Open the passenger door, lift up the step-in protector and remove it.
Pull down the plastic protection under the passenger glove compartment.
Use a sharp knife to cut a hole in the cable entry which is located on the other side of the firewall of the glove compartment, in the engine bay.
Route the included USB cable thru, you might need to use a screwdriver or other thicker object to help push the cable through.
The USB cable routed through the firewall, place the cable under the glove compartment for future usage.
Lift up the stock ECU and push it outwards to remove it.
Mount the MaxxECU PRO unit with the included screws, be careful about the mounting position, see next step.
Example of MaxxECU PRO mounting position on the Corvette C6, be sure to have enough room between the MaxxECU PRO brackets and the door (red arrow), try to open the door fully before securing the MaxxECU PRO unit for good.
Install the MaxxECU adapter harness into the MaxxECU PRO unit by clicking in all CMC connectors.
Note: for boosted applications, please mount the included MAP sensor hose into the pneumatic connector (green arrow) in the MaxxECU and put the other end into the intake manifold. (The Plugin solution uses the stock MAP sensor mounted right after the E-Throttle body, but that sensor does not work with boosted applications). Do not forget to disable the external MAP sensor in the configuration for MaxxECU to understand to use the built-in MAP sensor instead in this case.
Mount and secure the included USB cable in the MaxxECU PRO unit.
Connect vehicle harness connectors with MaxxECU adapter harness.
Route the included Bosch LSU 4.2 sensors to each exhaust pipe, depending on your installation you might need to weld a new bung to make the sensors fit in the exhaust system.
Note: Make sure you route the LEFT side exhaust sensor to the WBO 1 connector, and the RIGHT side exhaust to WBO 2 connector, all cables are printed with their function.
Mount the included USB antenna.
Hide the extra EGT mini-K connector if they are not used.
Use some wire straps to secure the stock vehicle harness from flying around.
Put back the wheel house mudguards, and reinstall the fender and frontspoiler. Secure all screws.
Connect battery.
Ignition on.

Optional: Install external intake air temperature (IAT) sensor
Some vehicles are not equipped with an intake air temperature (IAT) sensor and MaxxECU plugin solutions do have the
option to add a sensor.
The intake air temperature (IAT) sensor should be mounted to sense fresh air flow going into the engine.
Depending on the intake manifold construction, the position of the temperature sensor is not given, but preferably mount
the sensor in the intake, or in the pipe before/after the throttle.
IAT wiring
MaxxECU plugin solution are equipped with an optional 2-pin connector for optional IAT wiring.
Mating connector and wires for external IAT sensor.
Note: This plugin solution do take use if the stock IAT in the MAF, but usually the MAF is removed and the extra 2-pin GT150 connector is parallel wired with the MAF IAT.
