does my 97 f250 have a obd II port if not can i still get a chip for my truck it has a 460 in it i want more power and need help thank you.

 

Check out fordfuelinjection.com for details on the differences between these two systems. OBD1 trucks have the 5-pin test port under the hood, while OBD2 has the 16pin port under the dash. You truck will have OBD1 which isn't as smart, but the upside is you don't need a tuner to get more power, you just have to bolt-on parts to get more air through the motor, headers and exhaust, indiction, and cam upgrades.

 

If you have the over 8600 GVWR F250, you do not have OBD-II. I'm not sure that the 460's ever had OBD-II. Don't know about a chip, but I don't see why there wouldn't be one available.

 

Save your money do not buy the chip, open the motor up so it can flow more air, as Conanski has suggested. Air flow = power.

 

thanks guys

 

more air in and out is what makes power.

 

how do i get rid of my top speed limiter

 

Bansheeduner i was wondering the same thing..The guy at the auto parts told me that i needed to get a special chip for my ecm since i got a obd1 which i'm almost positive is what you have..

 

These trucks have the aerodynamics of a tool shed, I seriously doubt you have ever been anywhere close to the speed limiter, which should be up around 125mph.

 

I got 4:10 gears overdrive and the 460 118mph is where the speed limiter kicks in..There is really no need to go that fast in a truck..There all good for show and go up to 80..But after that there doggy.It just pretty much to have it off in case a ricer comes along..LOL..

 

With my new toy(TweecerRT) I can do stuff like that in seconds, but you have to have an EEC that's supported by a tuners first... of course. The big problem is that nobody has ever reverse engineered the SD computers found in these trucks, they're usually ditched for SEFI Mass Air versions as soon as people start hot rodding, so the necessary files needed to make changes with a chip or tuner have not been created.

 

ive been to the limiter allot of times... its right when it changes in to 4th and stays at 3000 rpm or so i dont remember presisly the rpm. but what mph is the limiter with a 4.10 's?

 

i get 118mph with 4:10's my friends dad is a cop and we asked him to clock us one night..dodge ram with 4:10's is 105..And a cheby s10 is 98...

 

hit mine several times the truck has a 7.5l not a 5.9l thats why maybe you cant hit your limiter i just want a chip if i cant get a tuner

 

The factory speed limiter in the mustang computer is 127mph if I remember correctly.. so no I've never been there. My truck pulls just fine up over 100mph.. but I could care less because no matter what motor is under the hood, it'll never haul like this thing...
