Rusty, crushy, but trysty.

Truck has been busy, it hauled a lot of rocks for our garden, first load was 2 scoops which they said was about a ton per scoop. The rocks were nice enough to put my back out, so i have not been able to do much the last month. I have also been working on fine tuning the engine. I think i got most of the problems ironed out this afternoon. My test run had no stumble from idle no matter how much throttle i gave it, slow speed and idle seemed to be much clearer now. I still need some cold weather to work out the cold warm up.

looks great! reminds me of my grandpas 81 scottsdale and my old 78 2wd truck, miss the darn thing, my grandpas truck is ready to break in half! whole truck but drive train is junk haha. your truck would look good with a white top! it would defiantly split all that blue up!

Found that i had a bad spark plug, threw new plugs and wires in it, wow much better low end. It is getting annoying finding out so many of the new parts i installed are showing to be defective with so few miles on them. I will be doing a 180 mile round trip tomorrow i am really interested to see what i get for milage now that my lean cruise is working.

Well did my round trip, not quite what i was hoping for. 190 miles total, about 8 miles town driving about 50 miles 2 lane cruise at 60, the rest interstate with cruise at 66. Had a pretty good wind blowing today that didnt help but avgeraged 14.5MPG.

Ordered a few more parts. My dr vent window gasket has cracked up really bad, nice quality on that. I decided to replace the dr fuel tank sender since its so far off, wish it was an easy job. I also ordered a window vent shade, hopefully that will cut down on the noise. I found out a couple of key tuning parameters for anyone who tunes there own computer, i will put it here in case anyone ever looks. The first is INT delay VS airflow, this is to compensate if you move your O2 sensor further down stream, i multiplied mine by 2.5 since its about 2.5 times further down. The next will help you tune with an aftermarket cam. first PRP-Gain VS O2 and PRP Gain VS Flow, reduce these by 25-50% depending on your cam. I did 30%, i have no surgeing at all at slow speed and my idle is much better. I wish i would have found these when i first starting tuning my chip.

Installed the window vent shade, much better, almost all of the annoying wind sound from the vent windows is gone.

Well I caught up on some little issues that have been annoying me. I replace the water pump, thermostat, TCC solenoid and harness, changed the tranny fluid and filter. I also was having some issues with the defroster, found my a small vacuum line under the dash had disconnected. I also pulled the box back off and replaced the dr side fuel sending unit, it was much easier than trying to drop the tank. Gas gauge went from empty to half a tank, much nicer.
