Some people just can't get enough boost, for those of you who need more than 21PSI of pressure then we can fit a 400kPa sensor, this is capable of boost pressure up to 38PSI!!
MS1-Extra ONLY see HERE for MS2-Extra
If using MS1-Extra then when installing the MegaTune software ensure you select 400KPA Map Sensor setup when asked rather than the Standard Sensor setting:
If you have already installed the software then all is not lost, just run MegaTune and select File - Configurator:
Select Car1 - Settings.ini - Settings - MAP_SENSOR
At the top of the page youll see a drop down list, just incase you need to know, the standard MS ECU MAP sensor is MPX4250, select the MPXH6400A -- MPXH6400 - 400kPa setting then goto File and Save.
Your MegaTune software is now configured to use the 400KPa sensor, all you now need to do is ensure the MS ECU has 400KPa sensor selected in its settings. To do this power the MS ECU up and connect MegaTune. Goto Basic Settings - Engine Constants and ensure that MAP Type is set to 400KPa:
MS2-Extra ONLY
When using MS2-Extra then after installing the MegaTune software, power the MS ECU up with MegaTune connected and go to Tools - Sensor Calibration:
Ensure the settings are all set with these figures in them then click BURN TO ECU:
For your information the standard MS ECU
MAP sensor should be set to:
Value at 0.0 volts = 9.3
Value at 5.0 volts = 260.9
