Turbocharging your MS45 or MS45.1 ECU BMW? This adapter harness will let you run an aftermarket MAF WITHOUT having to hack apart, repin, or splice your harness, fully reversible! Order the adapter for the MAF you wish to run, insert the stock MAF plug into the grey connector, plug the other end into the new MAF (and IAT sensor if optioned).
Running an aftermarket MAF will require a tune.
HPX options should work with any 05-10 Ford Mustang style MAF, Part numbers for the Audi MAF are 077133471K (VAG) or 0 280 218 08 (Bosch, * = placeholder for multiple numbers or letters)
HPX + M50/52/54 IAT sensor is highly recommended for using the HPX on stock ECU, the stock ECU tends to have difficulty reading the HPX IAT sensor due to too low of a pull up.
The "Connector Only" option will come with a connector, 6 wire seals, and 6 pins. You will be in charge of wiring and pinning. We suggest gently prying up on each pin's locking tab just slightly before inserting to ensure they lock properly.
