I am new I apologize if I dont do this right.

I am a shade tree mechanic trained by my father who I would normally consult on this but he is no longer turning wrenches here, God rest his soul.


I have a 92 F150 5.0 L with tow package and twin tanks. I have had the truck since June and it has been in the shop three of the last four months trying to get a fuel system issue resolved. After three months, thousands in parts and bills I did the non-popular option of a carb swap. The shop put in a 4 barrel manifold, weber 600 carb (Edlebrok) with a USShift Quick1 controller and thier TPS and wiring harness.

When I first got the truck back it was running good but shifted really hard into second gear. I was encouraged by the shop to download the software and tune the profile, so I did. I downloaded the profiles and followed the instructions from Baunam/USShift and still have issues. I have called, left messages and sent e-mails with no response from USShift to help.

Symptoms:
In drive (with or without O/D on) the truck is slow to take off and sluggish until it gets up in RPMs and into 2 or 3rd gear. In reverse, 1, or 2 it does not have this sluggish response.

I have tried all the profiles for the E40d and currently working with the fast lightening profile.

What I have tried:
-Veh speed sensor set to 2wd or 4wd High range axel 4.1 tire 29.5
-TPS Idle TPS Voltage 1.06 and w.o.t. TPS voltage 4.22 (set by capture feature in program)
-Converter Clutch set to basic settings with min MPH 49, max TPS 3.0 Min gear 3
-Speedo output disabled
-manuatronic pushbutton shifting disabled
-manual low control downshift set 13mph and 1-2 up set to 2686 rpm
-Gear ratio set to standard
-drive control switch set to normal lamp on o/d off
-range sensor is set to analog (pre 1998)
-trans type set to Ford E40D and 4R100

Any ideas??????

The truck was one owner, has only 44,880 original miles and looks great with no damage

I wonder if the Conv Clutrch setting for the Max tps need be adjusted to match the TPS WOT ???

 

I think you need to go to a c6 transmission with a carb swap. Or I would go back to the efi system and stay with that, it's a much better system.

 

You can run an E4OD with that controller and a carb.

It's too bad you took it to a place that had no idea how to fix your truck. If you had taken it to a competent shop you'd have the truck running fine and a lot more money in your pocket.

I don't know ANYTHING about how to make those controllers work. But I've heard they do work.

 

With the laptop connected view the dashboard at the bottom of the screen,when in "Drive",is the trans starting out in 1st gear?
