Introduction

The SSSMCK (SSSQUID MAF CONVERSION KIT) is the first and only retail-level kit that not only properly reads and filters a MAF signal for use with a stock ECU and tune, but also allows live data-logging with our Buoy application.

It is plug-and-play and can directly replace the stock VAM. The kit can properly convert a variety of different MAF signals into a signal a stock ECU can process. What this means is that this kit does NOT require a special tune to work. However, when using the Variable TPS or MAP Sensor add-ons, a retune is almost always required.

This kit is designed to work with the BMW M20, M30, M40, M42, and S14 engines. However, due to a lack of availability, the kit only comes with a connection for M20/M30 engines. For use with M40/42 and S14 engines, there is some custom wiring required (cutting, splicing, and soldering). Please contact us for more information!

At the moment, the SSSMCK does require the purchase of a MAF (if using it in MAF mode), a TPS is required for TPS mode, but only vacuum tubing is required for the MAP adapter. There are multiple plug-and-play adapters that can used with the SSSMCK base kit, such as MAF, MAP, and TPS. Why is it not all-in-on? Because it is designed to handle a variety of different sensors as well as additional add-ons such as the Variable TPS kit or the MAP Sensor kit. MAFs are by-far the most common and most reliable choice, and are the only sensors that can be used on a stock, un-tuned ECU.

Converting from the VAM to the MAP Sensor will change your vehicle's tuning to what's known as Alpha-N tuning, which uses engine RPM and throttle position to determine operational values.

Converting from the VAM to the MAP Sensor will change your vehicle's tuning to what's known as Speed Density tuning, which uses engine RPM and manifold air pressure to determine operational values.

Hardware

At the moment the kit is in pre-release format. What this means is that it uses 3D-printed components along with early software and hardware. While it works perfectly well for most applications, there may be small bugs or glitches we are still working on. Please keep this in mind and CONTACT US with any issues or bugs you encounter and we will fix them as quickly as possible.

Software

The software used to control the SSSMCK is an all-in-one data-logging and flashing tool called Buoy. You can read more about it here: SSSMCK/BUOY

Installation

Installation instructions can be viewed on the INSTALLATION page!

Operation

The SSSMCK has an LED that displays operation and errors, internal error checking that can output specific codes to Buoy for diagnostics, dynamic short-term and long-term corrections, and the ability to tune various parameters.

Read more about this on the USER MANUAL page!

Selecting a Sensor

MAF

It's recommended to choose a MAF that supports 20-30% more power than your vehicle produces. It's generally not recommended to choose a MAF that is rated for over 50% more than your vehicle produces. So if your engine outputs 200 Hp, you would choose a MAF that is rated for at least 240 Hp, but no more than 300 Hp. Of course you can always use a higher rated sensor, but it does reduce the reading resolution, so sizing your sensor correctly can produce a much smoother and more reliable engine than over-sizing.

MAP

When selecting a Manifold Air Pressure (MAP) sensor, it's a very similar process to selecting a MAF: it's recommended to choose a sensor that supports at least 15% more pressure than your F/I setup will produce, but no more than 80% more. So if your setup produces an absolute manifold pressure of 1.65 bar/24 PSI, you would select the 2.5 bar/36.5 PSI sensor.

TPS

The kit supports just about any variable TPS. You can calibrate and program your TPS from within Buoy. The most popular TPS is the M50 variable TPS.

Supported Sensors

Please expect this list to grow as we develop the kit further!

Custom Housing

Some sensors are generally bought alone and installed in custom pipe housing because their OE mounting is directly in a filter box or something that can't easily be used, such as with many Subaru or Mitsubishi MAFs. In these cases, sensor housing size can be different based on what you're using. We try to provide settings for a few sensor housing sizes, but we can always provide something specific by request.
