Well I've been busy getting it running.Fred wrote:The other night while Peter was running engine number 12, about which he's yet to post, he was having some sync troubles.
My parents gave me this truck when I first got my driver's license. I think the theory was that it might not be the safest vehicle, but at 10 miles to the gallon so I wouldn't be able to afford to drive it very far. Originally it had a FE390 V8. I tried my damnedest to get some fuel economy out of that engine, but I never got it above 14 mpg. I ended up swapping a 300 inline 6 into it. It was a pretty fair loss of power, but it'd usually do between 16 and 18 mpg running down the interstate. The best part is that the lighter engine does way better going over snow banks.
I got stuck in this snow bank because the right hub wouldn't engage.
I originally built this ignition board for my Honda. It didn't go on the Honda because the 6-2 trigger wheel on the cam isn't precise enough to run the ignition. It needs a crank with cam sync decoder written for it. Since somebody's masturbation wrist is recovering from overuse I figured I could either spend several days failing to write a working decoder, or I could just wire the board up to my truck really easily since I already had most of the hardware to run an efi system on it. Boy was I wrong. A few days and three trigger wheels later I finally got it happy enough to drive around.
Both of these videos are with the 36-1 trigger wheel from diyautotune that Fred is talking about here.
The 36-1 trigger wheel before machining with the hall sensor that I never tried to use with FreeEMS. This was also my first try at mounting the sensor. I ended up with about 1/32nd of an inch of air gap.
In my completely sober state the first drive is rather boring. I took it down to the parts store to get some spark plug wires that fit the coil properly. In the second video I took it onto the interstate to get home, and it backfired a few times. Right now it's running the Hotel timing table with no map reading.
