Finally the true replacement for the Selin MAF Translator is here! The KLDA Transmogrifier is a direct plug-and-play solution to allow you to easily and accurately run true dual intakes (with dual MAFs) on the 300ZX!

Everything you need to know about dual intakes

In stock form, the 300ZX routes ALL intake air through a single MAF, and it then immediately splits into two channels (driver and passenger sides). The stock MAF can meter more than practically any other Nissan production car from the era, and is electronically limited to about 500whp worth of air.

To get around this limit, pioneers like Jim Wolf Technology devised early dual intake systems, which split the intake tract into two completely separate channels, with a MAF on one side, and a "dummy MAF" on the other. Because this configuration effectively means the ECU is only metering half of the incoming air, this also required an ECU upgrade which included doubling the MAF multiplier in software to make up the difference.

This worked, and allowed users to push past the 500whp limit without the need for an expensive standalone ECU, but running a dummy MAF on one side isn't perfectly accurate, and caused low speed driveability issues, which required further modifications and work-arounds to resolve.

Then, around 2011, the Selin Translator hit the market. Put simply, the Selin Translator acted as a "splitter," where the vehicle's MAF connector would plug into the Selin Translator, which would then connect to two actual MAF sensors side-by-side, eliminating the need for a dummy MAF, "low speed driveability" modifications, or even an ECU tune!

The Selin Translator was able to run in two modes: In ADD mode, it would add the readings from both MAFs together, then send a single value back to the ECU, so it was truly plug-and-play with no tuning or tweaks necessary. In AVG mode, it would instead average the values from the two MAFs, and send that to the ECU. This made it backwards-compatible with those who had previously performed one of the older forms of dual intakes, while also being more accurate, and still providing a pathway to get past the 500whp limit of the factory MAF circuit for those who needed it.

Despite earlier beliefs that a dual MAF was only beneficial to those trying to get over the 500whp limit, Specialty Z found that on a TT with only a pop charger, catback, and a chip tune, switching to a dual intake using the Selin translator would result in about a 30 WHP gain at the top-end!

Unfortunately, the Selin Translator is no longer in production, leaving a huge gap in the Z32 world. Thankfully, KLDA and SpecialtyZ have brought a full featured replacement to the market, with all of the same functions and benefits as the original!

ADD vs AVG Mode

The KLDA Transmogrifier can operate in one of two modes, selected by a switch on the device itself.

• ADD: Use this if your ECU is stock, or configured for a traditional "Single POP" or "Single MAF" intake. This will read both MAFs, combine their value, and send it to the ECU. As far as the ECU is concerned, it's still a single intake, but bringing in more air than before!
• AVG: This mode can be used if your ECU has been configured for a "Dual POP" or "Dual MAF" setup. This is slightly less accurate than ADD mode, but still perfectly safe and won't cause any driveability issues. More importantly, it effectively halves the voltage being sent to the ECU, meaning it allows for you to get past the 500whp limit, or just upgrade an old school JWT dummy MAF intake with true dual MAFs!
