Eedbrock Pro Flo 3500

Don't really know where to put this but it is computer related.

Have any of you guys had an experience with the Edebrock pro flo 3500 system that can be fitted to a SBC.

I have one on my Chevy Nova that I drag race for fun at run what you brung events in the UK.

Anyway I am not getting any display on my controller module so I can't change any of the settings. Luckly I have a pretty much how I wanted for drag racing before it stopped working.

I bought the setup second hand with the engine that's in my car and when we first set it up it stopped working, then it came alive again of it's on accord a day or so later. Only this time it has not worked for 3 weeks now.

I know that the tunercat software will work on this system as well as my LT1 Z28.

Anyone got any suggestions?

I got the controller module working, I checked the connections on the 9 pin serial connector where the controller module plugs in. I found that the earths were bad so I spliced in a new earth and I now have my display working.

So now I can tune my engine again when I go drag racing.
the pro flo uses the controller module instead of a laptop.
Thanks to my buddy Mick for help on what to check.
