17 Escalade tach signal

[ddedrick85]

Twin turbo 2017 Escalade I'm trying to find a tach signal to hook up to an eboost2 boost controller so I can dial in boost by rpm.. And I can't seem to find anything on it. I was told ecm connector #2 pin 39 but it just has a steady 5v. I guess that worked on older models. Any info would be great! Thanks

There is only a replicated cam signal available. Will that work? It also needs to be enabled in the os if it is not already

I tried that and the Eboost 2 wouldn't read correctly.
