Re: 55*6BT My 55 w/ Cummins power
 

Maybe - first I need to confirm that the PCM is seeing the Engine Speed Sensor out. I just gapped it over the weekend. The original damper was broken when the '94 truck was wrecked, and the replacement damper (from Cummins) was a larger diameter. The sensor mounting tabs were slotted to align to either, but I had not gapped it to .050 until Saturday. It's gapped now, and wired from the PCM Tach Out to a Dakota Digital Diesel Tach Adapter which has an LED that flashes with pulses in. I haven't fired the truck with the sensor gapped, but last time I ran it wired this way there did not appear to be a Tach Out pulse train (no flash on the interface). I need to read the ESS output signal voltage and see if it changes when it's over the notch in the damper. Just really hard to get to it, and I hate to splice into the sensor cable but I really need to see the voltages.

And yep lots of hours in the rad cover, but it came out even better than expected. I just ordered a new master cylinder reservoir - the last of the old cruddy parts. It should look pretty good under the hood when I get it all painted and cleaned back up. It's really crowded under there - even with all that engine set-back. But I had to have the big radiator, big intercooler, and of course A/C and that stuff had to go somewhere.

Well it's looking great!! When you get all the bugs figured out you and everyone else will be loving it.

Well the junk hood hinges finally pushed me over the edge. The left and right hood hinges are not symmetric - they open and close on different arcs. The right side is 2 inches high when closed. I just ordered a pair of Eddie Motorsports polished billet hinges MS149-22P. Found some on fleabay and did a chat session on Summit. Sent them the link and they matched the price! Regularly $700, dropped to $571.50. Still redonkulous for a pair of hinges but should be a really nice touch for the engine bay. Being a drag racer, I'm very particular about the engine and engine bay. Also have a new reservoir for the master cylinder. This thing is packed under the hood like a late model truck. All complete there except wiring the cruise control canister, installing the relays for the grid heater, and securing the main harness. I plan on sneaking it down the highway to a local car show Saturday morning.
