VTT BMW Plug and Play Pre AND Post throttle 5-Bar (58 psi), 6-Bar(72 psi) Map Sensor Kits

Description

Looking to up your boost limit on just about any BMW vehicle that runs a 3 or 4-wire BMW map sensor including but not limited to S58, B58, N54, N55, S55, S63, B48, B47, B42, B57, B46? We were too, so we decided to make a very easy plug-and-play kit for 3, and 4-wire BMW map sensors. These kits will allow you to completely replace the 3-wire sensor with one of our sensors, and leave your stock 4-wire in place for IAT sensing. Then our 4-wire harness will move the power, ground, and sensor signal from the factory sensor to our sensor. These sensors have the proper scaling which will allow your tuner to simply change your map sensor scaling in the tune, and the factory ECU will be able to utilize the sensor voltage with no problem. We are offering these in 5 bar (58 psi), and 6 bar (72 psi), and each comes with a plug-and-play harness, and optional fittings for ease of installation.

Note: For the S58/B58 our Factory style Pre-Throttle map sensor is also 5 bar, and will work fine coupled with the post throttle kit, but the scaling is different, if you want matching Voltages Pre/Post throttle you can run two of these.

Features include:

Features include:

• Plug and Play harnesses with no wire splicing
• Output wire for connecting a PI or external controller to your post-throttle map sensor for the most stable signal that is not affected by throttle closure
• Different fittings are available for your plumbing needs.
• Can have matching voltage signals for pre/post throttle for ease of tuning, and boost reference

Sensor Specs:

• 5 bar map sensor. (-1 bar to +4bar)
• -14.5 PSI to +58 PSI Absolute pressure sensor
• -14.5 PSI = 0.5 Volts,   58 PSI = 4.5 Volts
• Outputs 0.5V to 4.5V
• Input 5V
• Accuracy 0.5% of full scale.
• Heavy duty Stainless steel body
• 1/8″ NPT thread
• Compatible with all EFI and data logging systems

• 6 Bar Map sensor
• -1 bar to +5 bar map sensor.
• -14.5 PSI to + 72.5 PSI Absolute pressure sensor
• -14.5 PSI = 0.5 Volts, 0 PSI = 1.16 Volts, 72.5 PSI = 4.5 Volts
• Outputs 0.5V to 4.5V
• Input 5V
• Accuracy 0.5% of full scale.
• Heavy duty Stainless steel body
• 1/8″ NPT thread
• Not compatible with FAST XFI or HP tuners.

PLEASE NOTE: IN SOME SYSTEMS YOUR ECU IS GOING TO BE HARD-CODED TO A CERTAIN BOOST LIMIT, AND YOU WILL NEED TO SPOOF THE SYSTEM INTO THINKING IT’S MAKING LESS BOOST THAN IT IS. WHEN THIS IS THE CASE YOU SIMPLY LOG SENSOR VOLTAGE, AND YOU CAN GET TRUE BOOST THAT WAY. FOR BM3 USERS, CROM2, AND REV2 BOARD WORK PERFECTLY WITH THESE SENSORS, AND NO SPOOFING IS REQUIRED.

ALSO NOTE: SOME PLATFORMS CHANGE THE PIN ORIENTATION AROUND, YOU CAN EASILY UNPIN, AND REPIN THE PLUGS TO MAKE SURE YOU HAVE THE SIGNALS WHERE THEY NEED GO
