Well, I took a break from the install and concentrated on bodywork, paint, and getting the Scout registered and back on the road. Once I was comfortable that it was running properly, I dove back in last weekend. It's a 1980 Scout II with 345, 4 spd. The harness and TB donor was a 1989 k5 blazer with 5.7. Most of the other parts were purchased new. I used Hamilton's adapter plate, usb cable, and initial chip. I did have one issue with a knock sensor on the install as the first one I received off of amazon was straight thread instead of NPT. The price was too good to pass up, but I guess you get what you pay for. Other than that, the mechanical part of the install went pretty smoothly. I got the initial timing set and got it idling, although this took a little while as it was popping, backfiring, and not taking throttle. It is currently set at 1 degree ATDC now as the ignition module that I mounted to the distributor is hitting the water pump housing and not allowing me to go any further at this point. see pic. In the beginning it would not start or idle with the bypass connector plugged in, only when it was disconnected. The last thing I did last night was ground the third wire from the reluctor pickup in the distributor. I thought it would make a sufficient ground through the distributor housing, but I wanted to rule this out as a problem. This morning I tried it again before work and it idled fine with the connector plugged in and I was able to drive it up and down the driveway with just a little popping. I feel like the injectors may have just been gummed up from sitting for so long and that they are getting cleaned out every time I run because I really haven't done anything different (other than the one ground), but every time I start the truck it seems to run and react a little better. Does this make sense, anyone experience this before? I did not see the IAC pintel that is described , so I pulled the IAC from the TB to verify that it was working. It fired the pintel right out of the housing when I jumped the ALDL connector, so it is certainly working. I put it back together and verified that I do get suction through the port during cold idle. I verified that the TPS is working smoothly and was able to set it to .7%. However, I could not get the warm idle to go below ~725. This was with the bypass unplugged. Now that it will run with the bypass connected, I will reset the IAC and TPS and go from there.
