cj.surr Posted July 8, 2019 Report Share Posted July 8, 2019 As far as I can tell, this is not possible with the G4+. It would be nice if there were a few options for smoothing sensitivity on analog input signals to suppress noise and spikes. For example, my water injection pressure sensors that are being driven by a 20hz solenoid, I can see every time the solenoid opens (150 kpa spikes - see image). Another sensor I am planning on adding is exhaust manifold pressure, and I am anticipating I will have the same problem. Thanks Quote Link to comment Share on other sites More sharing options...

Ducie54 Posted July 11, 2019 Report Share Posted July 11, 2019 Things like this on the G4+ I can't see being added. I run a T1 race pulse dampner on my Emap sensor. Works like a charm. Cheaper way is to run different size line restrictors untill your happy with the trend. Quote Link to comment Share on other sites More sharing options...

There's nothing overly complicated about it - it just averages a few sensor signal values. 10 year old Megasquirt software allows you to set an individual smoothing value for each input. Restrictors are not always practical/effective to add, such as in a water injection pressure. Peter Andersson 1 Quote Link to comment Share on other sites More sharing options...
