Boost MAP Sensor 7-Bar - Barb Fitting

These are our JRP 7-Bar MAP sensors, also referred to as a Boost sensor. We sell these for customers that possibly need a replacement Boost sensor for one of our gauge products, and we list below which of our gauge products use these sensors, as we do have two different types of Boost sensors used with our gauge systems.

We also sell these 7-Bar MAP / Boost sensors for people that are looking for an affordable yet quality MAP sensor to connect to a datalogger, or an aftermarket ECU. These sensors being 7-Bar are not super common, most boost sensors are between 2 to 3 Bar, so we have also listed these sensors up for those people that are looking for a boost sensor than can read well above the standard boost sensors found commonly in the market which read much lower at the 30psi or 45psi mark. 

Now when we say these sensors can be used with an aftermarket ECU, we mean simply for logging purposes, most aftermarket ECU’s come with a MAP sensor on the ECU itself which is used by the ECU to control vital functions such as fuelling and ignition timing. The MAP sensor on an ECU is possibly the most critical component of the ECU when it comes to controlling both fuelling and timing of the engine. These MAP sensors which are built into most ECU’s are accurate right down to 0.001psi in a lot of cases and respond to changes in manifold pressures at blistering speeds. The reason they need to be this accurate & respond at the speed of light is simply because they are the master signal making sure the ECU is doing what it needs to do perfectly. We DO NOT recommend using these sensors for ECU’s that don’t have their own internal MAP sensors, such as ECU’s like Microsquirt for example, or some of the Link ECU’s which don’t have a MAP sensor built in. These sensors while filtered and accurate, they don’t have that extreme resolution required of an ECU for pinpoint fuelling and ignition timing. While we know these sensors could most likely be used for this purpose and still work, their accuracy is more around 0.1PSI, in our opinion just short of what we would be comfortable using on our ECU’s for something as critical as fulling and ignition. As for them being used with dataloggers, gauges, or secondary MAP sensors on ECU’s for various logging reasons, they are absolutely perfect.

These sensors can read both boost and vacuum, with a range of 30inhg of vacuum to a whopping 101.5PSI. You can find the voltage calibration table for these sensors in the product photos on this page. These are a 3-wire 0-5v MAP sensor, so you will need to provide the sensor with a 5v power source, a ground and the third wire will be the signal wire you run back to your datalogger or ECU and off you go.

Below are our gauge products these sensors are used with, if looking for a replacement Boost sensor.

14in1 Multi Gauge

Edge 52mm 30inhg to 30 PSI Boost Gauge (Bought Prior To Aug 2022)
Edge 52mm Diesel 0-60 PSI Boost Gauge
Edge 52mm Dual Boost & EGT Gauge

**WARNING**
If you are looking for a replacement Boost sensor for our Diesel 0-30PSI Boost gauge, these are not the sensor to order, you would grab our 3-Bar Boost sensor for those. And also if you ordered our 30inhg to 30 PSI Boost gauge after Aug 22 you would also need the 3-bar sensor.
