Re: 1976 Square "Simple Green"

How come you don't run it? Struggling with this myself. They suggested it would run better with than without.

Re: 1976 Square "Simple Green"

Did you find anything out on the rubber isolation piece that goes @ the bottom of the pump (post 561)?

Building a small, high rpm engine with the perfect bore, stroke and rod ratio is very impressive.
It's like a highly skilled Morrocan sword fighter with a Damascus Steel Scimitar.....

Cubic inches is like Indiana Jones with a cheap pistol.

Never found one I could buy. Only ones I found came with a pump. But I won't need it with the Walbro the bottom part as you can see in the pic above the fat part. Well it sits perfect in the cradle that holds the pump. I will post some pics up so everyone can see.

Re: 1976 Square "Simple Green"

Now these pumps have purge holes in the base. So for the pump to work correctly and so it can purge. I drilled a hole in the cradle under the purge holes. It makes it nice to have a extra sender to mach stuff up on. Got luck on the first try. It will make drilling the hole on the sender I will use easy.

Re: 1976 Square "Simple Green"

Ray here.

I'm not a chev. truck owner but I do have the Fitech power adder setup
on my 408C mustang...works very nice!
What am trying to find out is if anybody has got the laptop tuning to work?
Tech has been less than helpful on this...

Hey Ray. I am wanting the laptop tuning also. But I have not had time to ask them or even look into that feature yet. Do you have it setup to use like that now. Or are you trying to get the software from them. We will need some software for tuning. For my other toys I have the SCT software I can tune with. As long as you got the money SCT does not care they will let you have it. I did read the FAQ on FiTech website does not look like they want weekend worriers trying to blow up vehicle when some people can't change a spark plug lol. Not saying you or I do not know by you know how some people are. Nice to see someone else on a different application is enjoying the FiTech like myself and others.

Re: 1976 Square "Simple Green"

I will say that the way you read the data logs on the FiTech is less than desirable. They just use excel. I want to look at a graph that I can scroll and zoom in on things. But you can use the excel just not as nice and clean cut IMO. I guess I am spoiled using SCT for so long and they are the industry standard IMO. But with saying that most people will just put it on and drive it and never worry or look at a data log.

Re: 1976 Square "Simple Green"

Ray here.

The laptop stuff has 2-D.and 3-D graphs with tracking and more tuning than
than most people will ever need.
my problem is getting it to talk to the car..

Re: 1976 Square "Simple Green"

Ray here.

That's one of my big stand up things..(easy to photo)
I have tried two laptops and two desktops and two different controllers.
I feel am just missing something simple..
Fitech help line has been very very good up till now...

For those who my care.
1.Using the timing control with a self modified MSD ready to run(3wire to 2wire)
2. Fuel commander for fuel.
3. After 3 new carbs-750-950-1050- the motor has never run better...
The Fitech is an 850 by size...I'm thinking it flows way more than that..

If someone gets the software working let me know...

Ray.

Somehow am thinking I my have drifted this tread....sorry

Tell me the steps you are doing with the laptop and tell me what FiTech told you to do. Let's see if we can get this figured out.

Told him in tank pump cause I thought the FCC was ugly lol. I am happy I got to speak with a guy who has installed these on different vehicles. Hell you will never know unless you ask. And trust me I have no issue calling and asking and *****ing when I have spent $1500. In my other posts about the timing control I was just repeating what a tech office guy told me. But the mechanic set me straight lol. And I am happy he did. Plus guys he has built a few C10's. Lol. Makes me feel better about giving them my money. And they are easy to talk with.
I am coming to this thread late so I apologize for asking a question about such an old post. (450) Did the mechanic say why you need a relay for an in tank pump and not for the "Fuel Command Center". I don't see the difference. You are running a fuel pump either way. The load should be the same. Also, does the relay work OK with the PWM signal from the ECU? The reason I am curious is that I am getting ready to install one on a friends 69 Camaro. Any help you can give me would be appreciated. I have another friend who put one on a Bronco and he had a problem with it burning out one of the pins in the power connector. I think it is the one that runs the fuel pump.

By the way, nice truck.

We never talked about the FCC cause I am not using that. The reason I used the relay which you would think would apply to the FCC cause it has a 340lph pump in it is...

Using the relay,will reduce the current going through the 6
pin connector on the system. Also the pump would always have the voltage it needs.
The PWM part is just a voltage reduction on the signal coming from the ECU, so as
long as it's enough to turn the relay on, the relay will supply full voltage
to the pump.

The PWM by the time it gets through the relay,
and the output has a super-fast PWM frequency that shows up as a constant
voltage by the time it gets out of the ECU. The ECU is just turning the
relay ON with this signal, and the pump is getting full
voltage.

On the ECU, the PWM only works when at low throttle and low RPM, and puts
out about 10 volts. Above that, it switches over to the internal relay, and
gets direct battery voltage and no more PWM. It's just a pump quieting
scheme, and not a pressure control thing.

Now everyone knows how the PWM on the FiTech works lol.

I run the relay and it is not causing a issue and it is staying.

And thanks I appreciate that. I like my truck also.

Re: 1976 Square "Simple Green"

Ray here.
At the risk of drifting this tread more.
The computer guy at Fitech has been on holiday for a week or two.
Till Monday or so.
So help on software has been limited at best..
My problem is down loading the KlineDriver_AAFF_FFAA folder.
Really its just finding it...... (this lets the two talk)

Ray.

The timing control really is nice if you can do it.
Not opening the hood to adj. fuel or timing on that 90+deg.day after getting a tank of crap fuel while sporting your best girl..Priceless.....

That would be Jeremy the co founder software guy you are talking about. Yes he has been off for the holidays. I will hook mine up here in a few and see what I can come up with.

Re: 1976 Square "Simple Green"

Thanks, your info is very helpful. Because of my buddy's problem with the Bronco I have already decided to use a relay for the fuel pump and your info tells me that is the right decision.

Thanks again,
Ronnie
