Gambi80 Posted April 19, 2010 Share Posted April 19, 2010 I don't know the wiring, placement, or proper names for the sensors you are attempting to fool but if you can round that information up, I can prolly figger out how to modify it to operate a little better for you. This is within the operating parameters the eproms inside the ECM are programmed to. If you can get the ECM flashed to provide more performance, then alter the external sensors, usually a significant improvement can be realized.Most external sensors are nothing more that a variable resistance output used for an input to some other device. After the parameters of the end user are known, the external inputs can be altered/modified to suit. However, ECM's are programmed with an operating window that most times cannot be adjusted. This is where the external "burners" come into play. Most anything can be worked with if an engineering drawing is provided to figger out what is happening internally. A good portion of the external sensors on an engine can be eliminated, (barring emmisions compliance) for better performance but the driver best watch the dash gauges. Modern engines were not engineered heavy enough to take the abuse they could be given if the performance is upped.I used to like working with the 4.5 Cadillac engine. Lots or power to be had out of that small package and still bust 25mpg. Another favorite from years past was the little 2.5 Chrysler Turbo II, and III motors. Very easy to get 300+ horse from them reliable but hard to keep head gaskets if run hard a lot. Both of these engines just took a little modification of the electronics to "wake them up" significantly. Same basic rules apply to anything that is electronic controlled via external sensor inputs.Tangent I know, but the same principles apply.RobThumb through that thread I posted on the "puter tricks" to get an idea of what I was talking about. I was just curious how similar Mack is to a Cat. I'm sure it's quite a bit different, but the brains across all brands have to gather the same info off the engine.

Gambi80 Posted April 19, 2010 Share Posted April 19, 2010 I left work since I don't feel good and I'm not going to class either. I been feeling like crap all weekend, I'm guessing the weather change. Since the truck was on my way home I decided to stop by and give it a real good look over. The tires are not as bad as I thought and the brake shoes look to have been put on before it was parked, the drums are rusted though.If I were you, since you say you want to buy the truck but not drive it for a year and a half (makes zero sense if making a payment), don't buy it till then. Chances are if it's been sitting for that long, what's another year. If it's still around, fine...if it's not, no harm done. Trucks are a dime a dozen, just because it's old doesn't make it any better and just because it's new doesn't either. But since it's been sitting for 3 years, I'd count on replacing a LOT of parts. Mine sat for about a year before I bought it and I'm still replacing seals. Quote Ever wonder how a blind person knows when to stop wiping?

other dog Posted April 24, 2010 Share Posted April 24, 2010 saw a yellow Freightliner for sale. Belongs to Jamerson Brothers trucking in Appomattox,Va. It's very yellow, don't know any more details.
