how to clear computer memory

i have a 2003 sd250 and would like to clear the computer of my driveng information,,, like how many times i hit the govener and if they have info stored on rpms, for they got a little high also. this happend for i am not rel happy with my 5.4 mpg it is 10 town and 12 hwy and has something like 3.75 not the 4.10 gears..... i do not always drive fast and do understand that your milage should drop if you drive hard but even if i drive slow it is the same,,, oh and the exaust pipe is always black and sooted,,, the dealer at pompano ford says that is normal and fine.

how to clear computer memory

Damn! Thats about what I get with my V-10 ( A little better sometimes)

Good Luck finding "the problem" though.

To reset the computer, I think all you have to do is disconnect the battery for a little while. How long, I'm not sure?

I'm curious to know too, I just installed a new exhaust last month and think I should reset mine too.

I read somewhere that you disconect the battery and turn on the headlights to kill the power left in relays and etc. Then conect the battery back after a hour(and turning off your headlights). Good luck!

Dropping the negative cable off the battery for 30 minutes should
clear all codes and the memory. You mention you went to Pompano
Ford... as in South FL? If so, I have a better dealer you should go
see in that area for SD truck issues... email me for details if you
want.

I am not sure that tatle-tale codes can be "reset". Codes can be recalled after an accident and I would think that by the time the vehicle is towed, the battery would have been disconected for more than an hour.

There doesn't seem to be much difference in mileage from 5.4 to 6.8. I think that a 4.30 axle in V8 will get about the same as a 3.73 with the V10. The V10 doesn't have to work as hard to push that 6500 lb truck. That and the fact that the V10 was only $600 more were the main factors for me getting the V10.

Isn't the tattle-tale log information just the last few hundred miles? Try driving it easy for about 500, then let them check it. But, if you are hitting the RPM limiter your driving habits are trying to tell you something. The RPM limiter is there to protect the engine, only you can protect yourself.

Best regards, see you on the road.
