Input from gmeter possible?
I want to add a second fuel pump to my fuel tank passenger side. Id like for it to come on and off based on the amount of g's the car is pulling. Is it possible to get input from the gmeter plugged into computer and get output to the second fuel pump to come on. Does anyone know if this is possible.
Thanks |

G meter on dash coms through canbus. So you are asking to create a device that looks for that signal, can read and interpret that can value, then based on the desired value switch on a pump. Geraldjust would be good to talk to about this as he is a can expert. To me it would be easier to trigger the pumps through other means. I am working on some arduino based setup but it will probably be most of the year before I am done with it.

Imho some mechanical means to solve the issue, eg. some baffles/plates to reduce chance of fuel starvation (IIRC in left-hand turns) for fuel pump, just enough to last for fuel for one long curve would be much cheaper, simpler, reliable. No uber advanced electronic gimmickry that will take much more time & money, if simpler means also solve that.
For example, how about this? |

Can confirm. Aero and e85 this isn’t enough. Either surge tank or dual pump setup.
