Following my recent posts thanks again for your replys,
I understand about barometric pressure and say 99 kpa does sound right for my area, Think the reading from my scan tool saying 3.7v all the time could be incorrect as was the same with engine running and not running.
Ive had the scope on the map vs maf tonight and seem to be getting a strange reading I think!
I would say the map/boost sensor is running good according to the readings on the data below but is the maf not right? I had 2 maf to try and one was new and was a bosch unit.
As matt said think I need some sort of data to look at eg; tis or Auto data as a bit lost without it as new to the scope and electrical side
Think the pico automotive course may be worth while in my case!
Well here is the data i collected today guys:
