B.Edmonds Posted April 29, 2019 Report Share Posted April 29, 2019 I'm having a Motec dash configured at the moment & was wondering if it is possible for the ecu to transmit fuel consumption based on injector activity. The supplier of the dash ( Cody Philips Racing ) mentioned that some ECUs have the ability to transmit this info. It's a Motec C127 dash.

Adamw Posted April 30, 2019 Report Share Posted April 30, 2019 Yes you can do this. The Motec dashes have a fuel used calculation that can predict fuel used based on a few different types of inputs. With a Link ECU you would use the "Fuel Usage Value" method. If the ecu has been tuned using the traditional fuel equation then you use injector duty cycle as the fuel usage input channel. If your ECU has been mapped using the modelled fuel equation then you will get better accuracy using the "inst. fuel consumption" parameter (you will need to set this up to be sent from the ecu as its not in the generic stream). In either case it is an approximation and needs quite a bit of fiddling/testing to get it calibrated right. Quote Link to comment Share on other sites More sharing options...
B.Edmonds Posted April 30, 2019 Author Report Share Posted April 30, 2019 Thanks Adam, I'll get this info over to the tuner !! Quote Link to comment Share on other sites More sharing options...
