Hey there fitted a Bosch 3.5 bar map sensor and using the additives and scalers recommended but my dash boost gauge reads incorrectly and only reads boost at high boost levels, just wondering what I have missed? Many thanks in advance [SMILING FACE WITH SMILING EYES]

Please make sure that you have set the MAP sensor in Dashboard.

Hi thanks for the reply but I meant the one in the cars dashboard in the middle and also even when checking boost at idle in the versatune dashboard with the right map sensor parameter selected it says -9.5 at idle, and at high boost it only reads like -6psi on the cars dashboard but in versatune it seems to read about right?

The dash gauge is calibrated for the stock MAP sensor. You will have to ignore that.

Ok thanks for the replies! Got the bnr s4 installed end if last week, wow what a turbo, just currently dialling in my maf cal so I can start adding some boost as currently set to 0 per cent as my old k04 decided to become a mobile smoke machine haha

Hey there just a quick one I've finally starting tuning the car as was using a second car but I keep getting the fault code p0069 map barometric pressure correlation but I had changed the values for the sensor in the tuning part of versatune and flashed the map, just wondered if anyone had any ideas? Thanks in advance

What calibration data are you using for your MAP sensor? ...And of course let us know what sensor is that.

Hi it's an 0281002456 Bosch sensor
Scaler a is 75
Scaler b is 1
Offset is -12.5
Just wondering how many of the tables on versatune I need to put them in the tube as there are multiples for logging and tuning? Thanks in advance

All 6 of them. You basically have these 3 values in pairs of two.

Ok thanks for the reply I'll have a look when I get my laptop back
