New Command Center...Version 2
Found this while looking at the Fitech website today. Anyone know anything about this new Command Center? Looks to be a true surge tank without the needle/seat regulating system used in the original CC.
It looks to be a big improvement from the 1st version. Haven't spoke with anyone using it. All mine are in tank pumps.
I just purchased this system with the 30002 FiTech and installed it in a 67 ford with 302. As for the pump itself, it is working fine. It seems to provide a constant 60psi of fuel pressure. This is my first experience with FI and going thru some issues with starting. At first I was experiencing flooding issues and then after adjusting the throttle position based on the IAC setting I was able to start the car and let it idle until it came up to temp. The IAC settings came down to 62 but not able to get to the recommended value of 10 or less. Currently having issues with hot starts now. Any advice on this issue. I have not driven yet, just wanted to get past the starting issues first.
Send a datalog at idle for 30 seconds over 170 degrees coolant temp. Also what is your cam setting and cam specs @.050.
cam setting currently @ 2. Specs are 220 duration with 0.498" lift (hydraulic roller)
Back at it tonight but the trials are not going well. Started up with a little increase on the throttle to try and get the IAC steps down but can not get it to stay running now, will stall out after about 30 sec of running. Backed off on the throttle setting to try and get back to a continuous idle and it ran for about 2 min before stalling. I noticed the vacuum was hovering around 10 in so I decided to change the Cam setting from 2 to 3. No improvement.
Not able to keep it running long enough to get up to temps so I took pics of the dashboard. This was prior to the cam setting change.

after a lot of research I finally found part of my problem. I was not using the pulse width modulation feature for the command center fuel pump. Once I changed this value from the default 74.9 settting to 39 the IAC step went to 1 and it starts right up.
You probably know this, but....
Adjsut your throttle setting to get it to idle. Do not worry about IAC until coolant is over 170. Tuning does not occur until over 170. Temp sensors are hit and miss on quality. I usually throw the Fitech one out and buy a Delco.
back at it tonight. the car will start up cold fine with no issues and will idle for several minutes but before I can get it up to temp it stalls. Once the stalling occurs it is difficult to get it started back again. Something seems to be triggering a sudden change it the unit because the display goes black first and then it stalls, seems like an electrical issue but the wiring connections are solid. Any ideas? Also, the IAC steps are where they should be hovering around 8 but as you mentioned it is not quite up to temp (about 150f) so no learning is taking place yet.
Make sure your alternator is charging and your grounds are good. I have had similar issue before and it turned out I didn't have my carb studs tight.
