First Gen Camaro Tic Toc Tach Anyone successfully wire this 68 tach into an LS3 E38 PCM yet?
Here is what I have so far......
In your case set G1201 (Tachometer type) to “Crank”. The tach output will then be on connector C1 pin 48.
I’m not sure where to set your G1202 & G1203 values. In a Gen III with a 24x CKP these would be set to “6” for a 4 cylinder Tach (OEM), and “3” for an 8 cylinder Tach.
Not sure where to set the 58x CKP values … have yet do one …
PS this runs the tach but its off about 25%
G1201 Crank
G1202 "6"
G1204 "6"
