Proflo xt help please :)

[Turbohotrod]

Hi im jesse a mechanic from a restoration company in adelaide, we recently have a cobra come in that has a proflo xt system. I have no history on the vehicle or who last tuned or fitted the system.
.it has a issue in cold start where it needs start ya bastard sprayed to start. But once warmed up it fires up all the time

the issue i am having is.
i installed the software and set to the correct com port and can connect to the vehicle. But as soon as it tries to sync it comes up with a error saving the map.
ive tried registering the ecu # and still made no difference, i am not sure what to try next.

any help will be appreciated

thanks jesse

Theirs 2 XT systems
1. Regular XT.
2. XT Plus.

Sounds like you might be using the wrong software?

Hmm ok i thought i had the right one.
ill send a picture of the ecu.
and ill fire up the computer and see what one i have

That's a XT unit. Not a XT Plus. Do not use any software for a XT Plus. The unit will lock-up.

You use the software, and manuals for the Pro-Flo 2/ Pro-Flo XT from this link: http://www.edelbrock.com/automotive/...-support.shtml
Don't use the XT Plus/Sportsman software on the same page!!!!!!!!.....you can read those manuals. Because they have better information about using Edelbrocks EFI systems.

You should ask the customer where his handheld unit is. It plugs into to ECU, and is very easy to use. Much better then using the software to just adjust the fuel priming.
Part numbers:
Calibration Module #35360.
Calibration Module Cord and adapter #35370.

Ok thanks ill try again. I did try that other one initially. But done the same thing

[BITE_ME]

With the handheld. It will show the firmware number. The software must have the same version for the 2 ( ECU/PC ) to talk to each other.
You must save the file from the ECU to the handheld first. You don't want to erase the files on the ECU. Or you will have to spend a lot of time returning the system.

Ok guys so i finally got it. The issue was i was opening the wrong one for some reason eflash wouldnt pop up on my desktop fixed now.
ok so i made a bench test loom so i could take the ecu home.
i saved the map and opened in the editor.

ok so now ill post some pics of the settings that are saved on there to see if you guys can please help me with the starting issue.

ive noticed for some reason the coolant temp is fixed at about 298f?
and what would best to change the cold start too as it needs start you bastard to start. But once the car physically warms up it starts fine?

thanks in advance jesse.

Can anyone help?
sorry for the bugging

[BITE_ME]

What is the problem?
Does it need more fuel when cold? Or timing? Or IAC needs more closed?

[Steve M]

The water temp should not be reading 298 all the time. It should be the same as air temp on a cold start. The only way to correct that issue is to send the ECU back to us for repair. With the high water temp, there is no cold start enrichment, so that is why it is struggling to start. Too lean under cranking.

[Turbohotrod]

Damn i thought it was going to be something like that :/

[Turbohotrod]

How much would it be to repair amd how long.
also do you have replacement ecus we could just purchase one the customer keeps bugging for his car. I just want it gone :/

[BITE_ME]

You need to call the tech line 800-416-8628.

hey guys,
so I received the ecu back from repair THANK YOU SO MUCH for doing that and fast.
I put her in fire her up took her for a drive to clear it out.

now my question in well two of them its hard to start easier then before now the temp is reading right but you need to open the throttle or pump it to start it.
and in the test drive when it comes back down to idle even if just free rev it dies out and stalls

I found someone has played with the stopper on the throttlebody because they snapped the idle adjust screw. and also found the tps which should be at about 10 was at 33% at closed.
I fixed that but its still the same

what should I try change next

thanks jesse

p.s I wish I didn't take this job on haha such a head ache
