Dual Intakes just got a little easier on the Z32. The Version 2 Selin Dual MAF Translator, like its predecessor, offers accurate and easy conversion to a proper dual intake system. With true dual MAF air intake metering and plug-n-play installation this product allows you to upgrade to a dual intake without the need for an ECU re-flash. You could install one in the morning and take it for a cruise that afternoon. Even better, if you have the classic dummy MAF setup and have been considering upgrading to a true dual MAF, the product is DIP switch selectable to work properly with dual pop tuned ECUs. Combined with the elbow kit, power gains as much as 30hp/30ft-lbs have been realized on lightly modified twin turbos.

The new V2 design includes high quality OEM male and female connectors with the more modern quick release latch. No need to run wires, cut, splice or solder… just snap it in place and you’re done! The circuit enclosure is molded from automotive grade PA66-GF10 for strength and longevity in the harsh automotive environment Inside the case, the circuit board is rubber encapsulated to protect against water and moisture as well as combat vibration. Combined with the individual wire seals on the connectors the unit can be considered waterproof. The mounting bracket tucks the unit away conveniently next to the filters with factory fit and finish.

At redline the Nissan 300ZX fires at 350 cylinders per second. The translator’s high speed digital signal processor updates the output signal over 1000 times per second to ensure the most accurate and up to date information is available to the ECU at all times. In addition, each unit is individually serialized, tested, and tuned during manufacture to ensure 1% or better accuracy across the entire operating range. Flow bench testing in the “ADD” configuration shows incredibly accurate metering to over 800CFM! The “AVERAGE” setting in combination with a classic dual pop chip doubles that figure for truly wild setups.

In a traditional single intake setup, you hit the single MAF's limit near 500hp. The Selin Translator can be run in ADD mode to support two MAFs without reprogramming your ECU, but if you are looking to make over 500hp, you can pair the Selin Translator in AVG mode with an ECU upgrade tuned for dual POP. This gives you the best of both worlds--accuracy of dual MAF with the HP ceiling of a dual POP ECU! Additionally, if your ECU is already tuned for dual POP, it will already be compatible with the Selin Translator in AVG mode, and you'll get better accuracy than with your aging single-MAF setup!

The 2nd gen translator continues to offer digital precision, true dual air intake metering and easy plug and play installation... a combination that has proven to be a popular way to enable the power potential of dual intake paths with any intake hardware choice.

The new unit departs from thru-wall case wiring, instead opting for an ECU style 23 pin harness connection point. This serves a number of purposes. First, the subharness approach produces wiring that is far more robust with enhanced fit and finish. Second, it allows the owner to purchase a standard length unit and later upgrade to an extended subharness or to any future subharness options.

Laid out like a small ECU, the translator was carefully designed using industry practices.

The entire assembly below shows the removable standard subharness and the new reversible bracket.

A Bi-color LED light was added to provide valuable information about the health of your sensors, wiring, and translator unit. In normal operating conditions a green light will display for exactly 3 seconds after power on. This indicates that two sensors are present, providing voltage within their operating range, and the wiring to the control unit is fault free. By default, both the green and the red light indicate that the translator itself is functioning properly. Should it fail to properly operate, no lights will illuminate. Both red fault codes (1&2) then only apply to sensors and harnesses. Once triggered, the red codes will display until the unit is restarted. The lights are informational only and do not alter the calculations within the unit. The graphic below illustrates the lighting patterns for different conditions.

On the original translator, connector boots were chosen per the Bosch standards that spanned through the early 80's to the early 90's. Individual wire seals were not attempted then because of shorter warranties combined with the costs of the precision needed to form finer assemblies. Later on manufacturers adopted the single wire seal approach which provided significantly higher weather resistance and thus longer service lives. Although not authentic to the era in which the Z32 was built, the move to this harness style was the right choice. Many new replacement parts from the dealer are coming this way now and it's a move in the right direction.

The dip switch is now fully sealed with a conformal silicone boot that protrudes through the urethane potting resin. As before, it selects ADD or AVG programming with the direction indicated on the serial number label above.

The first version went through a number of changes to address the threat of conducted and RF power from high frequency HID ballasts. The ultimate rock solid solution was the implementation of a watchdog timer and a high speed startup capability. Starting in 2012, units labeled "WD1" could reset themselves in less than the time between cylinder firings. This fix has been proven flawless since. The 2nd gen unit carries on this functionality and is thus also fully immune to the electrical environment.

The removable connector provides a fully encrypted entry point for factory reprogramming units to future firmware versions that can include added functionality or other enhancements. I should emphasize that this is factory reprogramming and updates would require shipping if needed. How this would be handled needs to be worked out in the future but the functionality is there now.

The thought of implementing a blow through sensor arrangement was a thought before the first translator design ever made it to silicon. With careful calibration, blow through mass air metering can be very accurate and repeatable. For blow through applications others in the aftermarket have found that the blade style Hitachi sensors widely adopted by Ford produce fantastic results and are long term stable and reliable.
In a collaboration between Selin Design and Ashspec, a blowthrough mass air metering system was developed for placement in the 2.5" Ashspec intercooler pipes just aft of the intercoolers. In this collaboration, the sensors were calibrated for the translator instead of the translator to the sensors. The result is compatibility with 2nd Gen translators sold from today onwards with the eventual release of these sensors. An extended subharness with the appropriate connectors will be available through my new site. Ashspec is producing sensor housing that swap cleanly into their 2.5" piping system as well as the OEM pipes with appropriate adaptors. The release of this option was supposed to coincide with the 2nd gen release however work in this area is ongoing. The exact timeline is TBD but it is definitely upcoming.

But there's no need to wait... today's inventory is future proof! Enjoy dual intake power and add a blowthrough kit when you and the product are ready.

Ash had been running the blowthrough hardware pictured below without incident since mid 2013 and report fantastic drivability and an overall positive review.
