What if I can’t get a good Tach signal?

Some vehicles/motors can be a bit tricky to get a good tach signal from, If you are doing an LS swap and want to add remote start you are going to want to get a tach adapter as the LS motor is notorious for having a dirty Tach signal. A Tach adapter generates a square tach signal meaning it is a perfectly clean signal. We recommend using an Auto Meter 9117 Tach adapter or If you want a plug and play tach adapter for LS motors we recommend Auto Meter 9123.
