I would like to scale my MAP value that is read from the ecu so I can display the value in Bar on the IQ3.
The value in the ecu is in kPa, and I would like to display value in Bar.

So, 150kpa --> 0.5Bar
Cant really understand the scaling for the channel EFI MAP Press, so need help to answer if this could be done:-)

Raw data value A: 0 will become ????
Raw data value B: 1 will become ????

This means that would like the IQ3 to show 0 when engine stopped, and boost pressure (n kPa -100) / 100
t.ex: 170kPa -100 = 70
70/100 = 0.70

Anyone???

Sir,

What ECU module are we dealing with?

It`s an Vipec ECU

Help....

additional info:

IF:
Raw data value A: 0 will become 0
Raw data value B: 1 will become 1

Then:
IQ3 shows value 100 when ecu map is 100kPa
and tex IQ3 shows 190 when ecu map is 190kPa

So, this value is displayed correct, but want the value to be displayed in Bar.
Need help with the scaling, urgent!!

Anyone??

You can't convert absolute kpa to relative bar, but you could change to absolute bar. Then just subtract 1 in your head.

0=0
1=0.01
