Under forced induction use, the original MAF from BMW cannot read high enough air flow values for reliable use at high load. The MAP conversion is a simple, cheap and reliable alternative which takes less than 10 minutes to convert to.

Unlike with earlier versions of this kit, you now have no need to open the ECU and solder and de-solder certain pins - everything is “plug and play” and can easily be returned to standard at a later date if required.

Please note: This conversion can currently only be used with the Siemens MS43 ECU (standard for most M54 engines).
You will need to tune the engine ECU after fitting this kit.
If you choose not to use the MAP sensor mount, note that the sensor needs to receive pressure reference from the manifold itself - it cannot be mounted downstream from the throttle body.

What’s included:

-MAF to MAP conversion loom (plug in and forget - no soldering required)
-Genuine Bosch MAP sensor
-DISA blanking plate with MAP sensor mount (fits all M54B30 intake manifolds - check the diameter of the DISA hole if you’re using an M54B28, B25 or B22 manifold before ordering)
-Step-by-step instructions for completing the conversion (you will have to move some pins inside the ECU box, but do not have to open the ECU housing itself.)
-Works for both forced induction and normally aspirated builds

Blow Off Valve 50 mm V-Band
(Please also see alternate listing for Nuke Blow Off Valve FOR 50 mm Hose Connection)

50 mm piston valve with the highest flow capacity available. When it is necessary to be able to rely on the installation and function.

Designed with a oversized 50 mm valve; we believe this is the largest valve available with the highest flow capacity. The body and all internal components are CNC-machined from 6082 aluminum alloy, anodized for a long lasting, corrosion-free appearance.

Designed and manufactured to handle extreme amounts of power with the same hallmark as all of our performance products.

The Blow off Valve comes with one quick connect pneufit fitting, with oversized 1/4 connection for quick and actuator response. If needed, barb fittings are available.
