#4147, "RE: MS and low independence injectors" In response to In response to 4
What harness are you using? If you made your own, what type of wire is used for the tach signal?
Our wiring harness are made with shielded coaxial cable, and we advise our customers to keep the Megasquirt case from touching any chassis ground. So far none of our customers have complained about noisy tach signals, nor have we experienced it first hand.
