Okay Blas-
I hope you can help me with this one.
Chassis no. spo-2571, the tach will follow the engine rpm to about 3000 then will drop to 0 as the motor gains rpm. Tach will pick rpm back up at about 3000 again as the rpm falls. It seems to function normally at 3000 and under.
Back ground on the car is, Accel dfi Thruster controlling the timing thru the new MSD digital 6a. The tach signal is sent out via the tach output on the MSD box.
Any thoughts would be appreciated.
Thanks in advance.
