  2. MAP Level Triggering

    in G4x

    Posted

    I actually ended up ordering a MonsoonX now. Is the internal MAP sensor signal included in the trigger scope? If it isn't what would be the best way to set up MAP level trigger timing? Using an external oscilloscope?

    Thanks in advance for the help.

    Adam,

    Thanks for the response. I'll hook the pressure regulator to the airbox.

    Am I correct in understanding that you normally have fuel system type set to "none" for NA ITBs then?

    If using the MAP signal from the runner this would only give the correct differential pressure for that runner's injector. Wouldn' the other injectors have an unrepresentative MAP value (and thus differential pressure) when firing?

    I wasn't really thinking about safety, more thinking in the lines of having the injector characteristics right at idle and low load to get the best driveability possible. I may be overthinking this perhaps.

    Hi @adamw

    I was wondering what setting this setup will need regarding fuel system type. Should this be set to "none" as I won't have a MAP signal that can be used for the necessary compensations?

    I will be running a fuel pressure sensor as well if that changes things?

    Hello,

    I am currently planning the system for my car. I am planning on running an Atom G4X as the engine is fairly simple, it's a 2.0L CIH Opel. It will be run on ITBs with an airbox with a front mounted air intake. I expect this airbox to become somewhat pressurised at higher speeds. I am planning to run a MAP sensor from the airbox and set this up as the BAP sensor. Then I will also set the fuel equation load source to BAP. Is this the correct way to do this? I expect a 1.15 bar MAP sensor will be sufficient?

    I have a crank pulley trigger wheel but no cam signal. The distributor will be removed as I will be running COPs. Now, to run the injection and ignition fully sequential I am planning on running a second MAP sensor to one of the intake runners to use the MAP level sync function described in the G4X software help file. Does this necessarily have to be the intake runner of cylinder 1 or will any runner do? As I will need to drill and tap an extra hole in my manifold otherwise. Also, what does the MAP offset setting signify?

    Could anyone let me know if this is the correct approach? I haven't found any further info on this sync strategy so I hope this may also help others.

    Kind regards,

    Rob
