If you will kindly read the number 5 post in this thread, you will see that Danny mentioned the Reflashing of the PCM by means of a TSB for an update.



1988 F-150 Custom to XLT Lariat conversion, 5.0 EFI (formerly 300 I6), 5-speed M5OD, 3.08 rear gears (will be upgraded to 3.55's), Summit headers, Flowmaster muffler W/ dual 3.5" tips 24" long.

Yes I understand that ford will update and reflash the ecm. But as I stated before, this car has been in for service at ford many times, and if it was flashed, the speed limiter does not work. I drove this car when it was brand new from California to Alabama, it would go well over 100 mph and it has never once shut down. Dont really know why, but I cant complain about this car, we were trying to find a solution for Bobs Bird

Dave,

That could just be a fluke, you said it had been in for service. Well, maybe the tech reflashed the pcm and it somehow removed your limiter.

Hey stranger things have happened.


I was also trying to tell the person that posted right above me that if he had read the post made by Danny, he would have seen that danny had already made that statement long ago.

I almost hate to mention this, but I have a 95 F-150, 4x4, 302, 5 speed. This truck came equipped with 235 75 15's from the factory, with the 3.55 gearing. Mind you, this is a Canadian truck with Kilometers per hour on the dash, and a max of 180 KMPH (110MPH). Anyway, all was stock on this truck the day I put the needle past the 180 mark. I would never do that again, in this truck anyway too scary. I have to say, that I didn't buy the truck new, but since I have owned it, the maintenance and repairs were not done at a Ford Dealer.
It has a new computer now, cause one of my bonehead mechanics was changing the ignition module, with the battery hooked up, and it fried the computer. New computer sucks. It came out of another ford, not sure what, and the mech that did that job can't remember. Anyway, power is fine, fuel mileage is fine, but, when I take off in 1st, at about 20 MPH, the engine stops pulling, but keeps reving. Exactly like if you were holding your car with the brakes, and holding the gas to take off hard. It revs, but doesn't go anywhere. That's at WOT. If I let off of it, I can get up to about 25MPH , before I need to shift. Second gear, same story, 3rd, same as well. (in 20MPH increments) In 4th, hold on, cause it takes off like a bat.... Now, sometimes, when the truck is cold, (sitting overnight), It will not do it. 1st gear will take me right up to 30-32 MPH before I need to shift, etc, etc. This only happens once in a while.
Is it possible that this could be anything else other than the computer? Would a chip help this? Should I go have the computer reprogrammed? Or toss it out, and get a new one that works for this truck for sure? All ignition components are new (except coil), new fuel filter, air filter, and fuel pump. I should add, this happened in March 99, 2 months after I bought the truck, so I have been living with this ever since.

 

You really should post this to a new topic as it does not pertain to the original topic

Yeah, I realized that, but I thought I would take my chances with this thread. I am going to repost now.
