Remnant Performance MAP sensor adaptor for Hyundai Genesis Coupe 3.8 to run 2.0T MAP sensor for boost

***DISCLAIMER*** MAP Sensor Adapter is included in all Remnant Performance 3.8 Turbo Kits!

PROBLEM:

The stock Manifold Absolute Pressure (MAP) sensor on the BK1 and BK2 Hyundai Genesis Coupe 3.8 can only see a couple psi of boost before it can’t read any further. This presents a problem in that if the ECU can’t determine your boost pressure, it cannot adjust your fueling to compensate for it. In order to get around this in the past, we have forced the ECU into “Open-Loop Mode” where it stops “closing the loop” in monitoring the MAP sensor and simply dumps in the fuel that it’s told to in the table. While this methodology works, it doesn’t allow the ECU to properly monitor and control fueling and all the safety features that come along with that. In addition, in order to trigger an “Open-Loop” condition, we would have to set it up so that over 50% throttle would go into that mode. This means that partial throttle boosting, and even rolling slowly onto the throttle was simply, impossible. These two scenarios would keep the ECU stuck in a Closed-Loop condition and therefore, it would not be able to compensate for boost and could lead to a dangerous lean condition for your engine!

SOLUTION:

The MAP sensor on the BK2 2.0T Hyundai Genesis Coupe (sold separately) can see up to 28psi and shares the same electrical plug connector as the 3.8’s, but the problem is that it is physically bigger than the hole in the Intake Manifold for the stock MAP sensor on the 3.8 Genesis Coupes. Made of Billet Aluminum 6061-T6 and anodized black, our MAP sensor adapter mimics the interface of the stock 3.8 MAP sensor to the intake manifold on one end, and allows for the larger 2.0T MAP sensor to be attached on the other. Since the harness and plug is the same, all that is needed is an AlphaSpeed MAP tune to take full advantage of the capability of the new sensor! The new sensor, coupled with the RP MAP sensor adapter, allows the ECU to hit target AFR’s regardless of boost level by compensating for the correct amount of fuel based on the information from the new sensor!

So to recap, YOU NEED 3 THINGS to make this work:

1) Remnant Performance MAP Sensor Adapter

2) Delphi PS10152 MAP sensor from the BK2 2.0T. Here is a link to purchase it: Click Here

3) MAP enabled tune from AlphaSpeed. Your car will not run with the BK2 2.0T MAP sensor without it as the ECU cannot compensate for the necessary new scaling of the 3 BAR MAP sensor. DO NOT install assembly until you are with your tuner!!

After that you are good to go! Happy Boosting!!

*** Please Note: You must first install the new MAP sensor from the BK2 2.0T Hyundai Genesis Coupe into the Remnant Performance MAP Sensor adapter before installing the assembly into the Intake Manifold. Make sure to use lubrication on both the O-Ring for the new MAP sensor and the Remnant Performance MAP sensor adapter.
