Re: Pro flow 3500 in 68 camaro
Guy's , FWIW, I installed the 3500 proflow on my ZZ3 crate motor in my older 57'. I found out the amp box (where the module is) gets very hot so you might consider putting it somewhere it can get plenty of ambient cooling. Maybe on the grille area, hood latch support? Just splice the wiring to make it longer.
As for the fuel pump, unless the changed it from the early design and sealed flow thru model, I would look at putting it on the outside of the frame, rear q-panel , closest to tank. I also put the fuel pump relays close by, shield from water with a cover.
I had problems early on back in 2000 with the air ambient sensor, I believe its still mounted into the intake? I spoke with the Eddy engineer and he instructed to take it away from the motor and heat(it did not know what to do when temps was over 140į) so I plugged the hole and put it in the path of ambient air also. Problem was when it got hot (here over 100į), motor would surge like a blower car and I could not make enough changes with the controller to overcome it.
Once I got it working well, I was getting 23 mpg with a 3.70 gear and a 700R4.
Also,,if you happen to need a fuel pressure regulator(mounted between fuel rails just behind the thermostat housing) I have an extra. Its of no use to me now, sold car and I had a few parts left over.
