This is one of the many reasons to have an EMS:
I hate the fact that I run a twin pump setup that has no fail safes. There are way too many things that can fail and result in a melted down engine, period. I’m running a full blown pump setup and for feedback I currently have an LED that illuminates when the second pump has power, it doesn’t mean that its working just that the harness has power to the second pump. At least this tells me that the Hobbs switch and relay are working.
I just implemented a setup to provide a indicator/warning from the EMS that is driven off of the AFR values during load levels and throttle position settings. I’m using a extra low side switch output from the ems to drive a loud buzzer to let me know if the conditions are not appropriate for WOT.
I’m keeping a mind map going of all of the modifications I have to the ECU from feature tuning to wiring changes.
