I can't get my motor to run right it smells like its getting too much gas. I was wondering if anyone had ideas what to do. I'll try list all the info i can about my truck.

1989 F-250 4x4 AOD Transmission
347ci. D&D Motorsports Inc. Long Block
TFS heads
10:32 compression
stock intake manifold with 1.5in spacer
42lb. injectors
ford racing wiring harness ecu and mass air flow sensor
powerdyne 7psi supercharger

 

What size MAF sensor?

 

How is it tuned, is it a chip or Tweecer? If it's a chip, make sure it's still seated in the PCM.

 

Yeah... that's gonna need a tune to run anywhere close to half decent.

 

I don't know what size MAF sensor. It came with the wire harness kit the part # is FMS M-12071-A50. I got it from Summit Racing Equipment.
I have no chip in it. Its just the ECU that came with the wire harness kit.

 

I agree with Paul, that setup is going to need a custom tune. The ECU that came with that kit was not calibrated for all mods you have.

 

There are no tuning shops in my area. So what do I do?

 

Get a Tweecer or Moates Quarterhorse and start reading. Paul Conanski installed a wide-band O2 sensor to monitor his air/fuel ratio. You will need something similar to keep that beast of yours alive. It's going to be a steep learning curve if you can't find a shop to trailer that thing to or buddy up with someone familiar with the tuners listed above.

 

truck sounds badass, got any pics??

 

Where are you located?

 

X2

get a tweecer

 

Going to need a Wideband and tweecer or quarterhorse like stated above.

 

Ok i got a Tweecer Rt going to read up on using it.
I will try to get some pics soon.
I live near Ashland, Wisconsin.
Thanks for helping guys i never knew about Tweecer tuners.

 

ya pics, sounds badass..

 

I've been working on it for a few years now. Stripped it down to the frame and repainted it. did a little body work on the front end and put 2004 range rover lights in it. Need to get some paint touched up on the hood then I will get some pics.
