After market Tach works for 30 seconds... I installed a after market tach in my car. I made sure the connections were good and all of that. Also, I remember someone telling me a while back to set the cylinder tab to 4 on my tach because of the LS1's coil pack setup.
The tach works great for about 30-45 seconds, then the needle goes to 0. It is almost like the tach works when the engine is in Open Loop. Then when it goes to CL or warms up, the tach stops working.
If I let the car sit a while and cool down, the Tach will work again for about 30 seconds or so then go to 0.
Any help would be appreciated.
