We put this page together so our potential customers could get a clear idea regarding the costs associated with converting an N54 engine to port injection. Lets start by discussing the required components for a high performance application between the Nexsys Motorsport Kit (left) vs the MaxxECU Standalone (right).
HPFP Block Off Plate
Direct Injector Plugs
Port Fuel Injector Harness
Port Fuel Injectors
Low pressure fuel pump upgrades
Boost referenced fuel pressure regulator
An intake manifold with port fuel injector bungs
Fuel line for connecting low pressure fuel system to the intake manifold rail while maintaining the low side fuel pressure sensor.
Nexsys Motorsport Port Injection license key
MHD Tuning flasher license for flashing our custom code

Now that we have our list we can see that many of the required items are the same and therefore should be excluded from the value proposition going forward (since you would need them in either case). Now we will include prices as of 02/17/2024. Source for MAXXECU PNP Standalone: PNPECU.com.
Nexsys Motorsport Port Injection Software - $499.99
MHD Tuning flasher license (many users already have) - $120.00
MaxxECU Race ECU - $1444.00
PNP Complete engine harness - $710.16
Effective Total: $499.99 - $619.99
Effective Total: $2154.16
Another consideration when comparing pricing is the high import duties associated with the MaxxECU for overseas customers.
