Tunerstudio map sensor calibration help

Hello all,

I’m using tunerstudio for my supercharged b16a and I need help looking for the map sensor calibration numbers for a 4 bar hondata map sensor.

i move attached the map sensor info

What ECU are you using with Tuner Studio? -- I ask because the organization seems to change between various megasquirt versions, and I would like to use a project from something like yours.

I fired up my TunerStudio using an MS2 Extra example, and I found that the menu Tools->Calibrate Map/Baro... window gives you the chance to set this up,

Using the info in your picture, I would try setting a custom map sensor with Value at 0 volts (%) as -96.5, and Value at 5 volts (%) as 400.

Here is a picture of what that window looks like for me:

Hi David,

I purchased a standalone ecu called Pnpduino designed for b series honda motors. It uses the speeduino board.

thank you for the response

I’ll try out those settings and let you know how it goes

HiDavid,

Do I enter all this numbers in the picture?

I only entered the common map sensor numbers you mention

after start up as I rev the motor the cursor only moves to the right it does not move up the kpa chart

No, just the ones in the MAP sensor area. You should upload your project (you might have to put it in a "compressed folder" - zip file) for uploading. Then we can take a look.

What is the MAP value when the engine is stopped? I would expect close to 100 kPa, then it should drop when the engine is idling. If it's not changing, then I would check to see what the voltage was at the sensor, (both stopped and running).

When the engine is off and it is 20kpa

I played around with the numbers

0.0 volts 6

5.0 volts 400
