sluggish tach
I have an interesting problem. I just got my new setup running, and the stock tach is accurate, but slow to respond and slow moving when comparing it to the reading the haltech is putting on the laptop screen. Any ideas on what this could be? Also, i had been running this ecu/harness before on the same car with no issue.
setup consists of: PS1k e&j throttle body ls2/truck coils full function eng. trigger kit FD chassis. Before when it was working fine, i was running the stock intake manifolds, stock crank sensors. My tach output settings are 50% duty cycle, and 4 pulses per cycle. |
