I had an oil filled gauge I replaced it with which stopped the needle bounce anyway.

Well, since I had to put the command center over on the driver side, I only had enough of the hose they supplied to run the supply side. I guess I could've used that hose on the pressure side and got some cheaper hose for the supply but I plumbed the supply first. The hardest part about this install is dealing with my OCD and mounting everything in a way/place I am happy with. I'm still trying to figure out a way to run the fuel lines under the front of the truck that I like. This would have been so much cleaner if there was room around the battery somewhere.

I usually end up getting aeroquip lines made for stuff like this so just did my best estimate of lengths and ordered some pre made.

I used a heat gun and silicone spray. Wasn't easy but worked.

I used regular fuel hose to the FCC - low pressure.
The kit included line is for the high pressure side.

Yep. I bought 6 foot of regular low pressure to the command center. So is your up and running? How do you like it?

.
I also only got one filter

I checked the ports on the way out the door this morning and you are correct- the small plug fits in the one port on the rear (passenger side rear corner). I didn't realize that was the designated fuel return until I was reading through the documentation again. I had my carburetor fuel line going to that corner so had already decided in my head that that was going to remain the fuel inlet.

I am going to route my fuel line the same way as the original so I guess I will use the passenger side front port as my inlet. I don't want to run any fuel lines over any of the exhaust.

I could switch it but will go the aeroquip style lines sooner or later anyway so I'll leave it as it is for now. I'm going to end up going the same style lines on the low pressure side later as well.

thanks guys.

Glad you got her figured out

Thanks Steve. I plan on getting back on it this weekend and hopefully finishing it off.

BTW- those train horns and bell are freaking awesome. I would have way too much fun with that.

Awesome. You will love it. And yes the train horns are a blast lol

One thing I noticed that maybe okay, or maybe I have something wired wrong - but I don't think so.
But even with the key off, as soon as I plugged in the Handheld Controller it lit up. Should the Handheld Controller turn off when I turn off the key?

[steveo3318]

No the handheld goes to sleep it's perfectly ok. It goes to sleep 90 seconds after the key is turned off and you have to push the button to light it up even after starting. I like this in case I would rather not have it on. It won't drain the battery. I also had this concern and tech support told me this.

[LostMy65]

Cool, Thanks.

Got enough of the install finished that I could fire her up tonight.

Definitely have tweaking to do- it is really rich. So much so that I hope it doesn't take out the O2 sensor before I get it straightened out. I'm going to set my idle and go through the parameters again. I might have the cam setting wrong and it's giving the unit a real time trying to manage things.

It's great to have her running again. The throttle response seems really quick so I can't wait to take it for a drive tomorrow.

[LostMy65]

I might be mistaken, but I don't think the Target AFR should be bouncing around like that.
I seem to remember mine staying at 13.6.

I did a bit more reading and I saw I have to mechanically set my idle, then let the ecu adjust to it. I'll see what that does. I also have to revisit my cam selection. I got it running a bit late after a long day and didn't even run it again after I shot that first start video. It ran so I called it a win and shut things down.

It might be a good idea to go through each section and click 'Send to ECU'.

Went through all my settings again and saved them individually. Set my idle. The target AFR has calmed down and is stable. The idle speed seems to hunt around a fair bit.

Went for a test drive, and as is the general consensus, wow. I feel like I picked up 100 hp. I am throttle steering the truck in first and second. I actually scared myself a couple times. The only issue is it seems to be hesitant to come down from rpm when the load is removed (clutching or decelerating). I have to give the throttle a blip for it to come down. I'll have to make sure the linkage isn't binding.

I noticed I can get in and out of the garage without using the throttle if I am easy with the clutch. I used to have to play with the throttle like crazy with the carb to keep it from stalling.

More work to do and I still want to tighten things up but pretty pleased in the big jump in power and crazy throttle response.

[LostMy65]

Yeah, mine seem to be slow dropping rpms.
Mine was related to linkage.
I originally had the linkage in the middle hole. Then I saw a video where Ken (Fitech) recommended using the upper most hole. That did the trick for me.

Ok, cool. Thanks.

I was just reading in car craft how the new hot rods are set up intentionally to drop rpm slow for emissions and was hoping that wasn't the case with this- slowing down decal to help keep the O2 sensor clean or something crazy like that.

[steveo3318]

There is a parameter that must be adjusted if you want it to come off idle faster. Actually two. Mine is a standard and was really really slow to come off idle. After I changed them it acts like a carb now. Comes off throttle with the pedal not being slowly let down. It's not linkage trust me. I will find the parameters this afternoon and explain if y'all want

Yes please! That would really help out.

One of the most difficult parts of the install was making it all look nice. You can see the high pressure AN-06 line I used for my command center to EFI lines. I'm going to use the same on the fuel pump to cc later. I still have to run my (not a return line!) vent line back to the tank.
