Thread: Pro Dash 553-111 controlling 5V analog switch.

    Default Pro Dash 553-111 controlling 5V analog switch.

    I have a Holley Pro Dash 12.3" 553-111 with a Holley Sniper EFI and an Aeromotive brushless Eliminator pump P/N 18051. I'm trying to control the variable speed pump with my Pro Dash. The pump requires an analog 0-5V signal from the TPS for the fuel pump to switch from low to high. 3.7 volts actually to switch from low to high speed, at WOT. The Holley Pro Dash does have a sensor reading for the TPS. I'm trying to determine if it's possible to program the dash to tell one of the output pins to give the 0-5V signal from the TPS, "In Analog only". A pulse modulated signal will not work. If so, what pin would I use and how do I program it? Thanks in advance.

    No analog outs unfortunately. Looks like you could install a remote mount TPS sensor to run it. Everything I've read about Sniper is to not split that TPS signal. Or if you Google PWM to analog converters you can pick up a board to do that for less than $10, then you could use PWM out to control it. But the remote TPS sensor seems easier to do.

    I can't seem to find a remote TPS anywhere. If you know of where to find one any help would be appreciated. Otherwise, I may do the PWM out to control it. That will take some figuring out, but I understand the concept.

    I believe TCI makes a remote mount TPS. Andrew

    Default Possible Solution.

    I believe I found a good solution. I'll post once I've confirmed.
