manually track it gas bought(gallons) by miles driven... if you get 14 mpg or more....outstanding if you are driving a bronco with a 5.0 engine then by all means do the six liter tune explaned/discussed here on this board... if its a 5.8 just tune it & keep your foot off the gas..... NO FAST STARTS/STOPS

Nothing is easily available out of OBD-1 systems.

i wanted to see if there was something to help with the gas pedal so i can calmly use it and not worry about it, there was something but its only for newer cars where you plug it in and lets you choose fast or slow acceleration response

The gas pedal is mechanically connected to the throttle plates, it's NOT a potentiometer connected to the pedal which is connected to the PCM. If your right foot is too heavy, put a 2x4 under the gas pedal so you can't push it to the floor.

I was about to suggest a vacuum gauge. Pretty easy install, and it's probably the best feedback you're going to get. All you need is a tee in a vacuum line, or one of the barbs on the vacuum tree if available.

I bought a fuel injection book by Probst for my 460 swap. In it he has a anecdote on fuel mileage. Said BMW disproved that the notion to "drive like an egg was between your foot and the accelerator" from the '70s fuel shortage was helpful. The best strategy is generally to get to cruise ASAP while staying out of WOT operation. So he recommends accelerating briskly to the cruise speed.

A vacuum gauge is a good idea if you want to know about throttle position. It's essentially how a large chunk of Broncos control fuel delivery. I have one tied directly into the manifold for underhood troubleshooting, but one could be brought into the cab pretty easily.

Gas mileage will not be good regardless of what you do or monitor. Aerodynamics were an afterthought and the newest of us are still near 30 years behind in technology. It is what it is.

Awesome!!!! thanks guys ! :) ill check on vacum gauges and also i saw jet has a monitor to check the throttle position sensor and you wire it to the TPS and MAP but im not sure if this year has a TPS

That reminds me of the old Top Gear episode where a BMW M3 got better mpg's than a Prius head-to-head ... on the track, where the Prius was maxed out the whole time.

Tying into the TPS and MAP wiring sounds like significantly more work than adding a vacuum tee. We're talking a few hours vs a few seconds. Are there advantages to offset the extra, and more intrusive, work?

for a carb'd motor, you'd want to accelerate fast enough that your secondaries don't kick in, could just tune back the secondaries a little
