RESET Craziness!!!
I'm trying to trace down my resets I've been having recently, and I logged the last few pulls.
It just seems that anytime I get under any load it resets. Just changed my plug wires and plugs (gaped to .020).
Did the resistor mod, changing the 1K ohm ignition resistors to 270 ohm resistors. Any other suggestions? Also my TPS decided to not work for some reason just after the resistor mod, so I'm tracing that down.

Definitely need to find out why the TPS line died. Could be related. As for you msq I think you need to disable barometric correction. Search up on that. You don't have constant baro. correction on but whenever you reset if it sees say 70kPa it assumes that's atmospheric pressure. I'd say set the upper and lower limits both to say 101 and 100 respectively and see if that helps. As for resets, you need to find what's causing them. How are all your grounds done?
Looking at your datalog....

Ok, got that taken care of, but I have some other stuff to look at too.
Also, looking at my harness, what should be on terminal 2I? Looking at the wiring diagram, the wire goes to the TPS, but I have never had it hooked up (and I have had a TPS reading in the past).
The grounds are all just factory grounds, with the black ground from the MS connected to all the grounds in the factory harness.
Also I have uploaded the wiring chart that I have everything through.

Not sure what 2I is without looking it up. But definitely look that up and make sure nothing's amiss. Go over ALL your grounds. Remove and clean all of them and bolt them down tight. Do the battery connections too, these are also critical. Double check the CAS wiring. I never used a CAS but I believe those random spikes in the RPM can be contributed to a dying CAS. A search will yield more info on dying CAS symptoms.
How is your wideband wired up?

That's a no no. Go buy an "add-a-fuse" circuit from Autozone for 3 bucks and put it in the windshield wiper fuse. This will give use fused switched +12V power to feed the wideband. This is needed to get it seperate from the MS and also because the wideband should not be on while cranking, only when key is in the run position.

Yeah, you've got noise, resets, and RPM spikes. Bad ****.
First, the LC-1 doesn't give a **** where its +12 comes from, but it wants to be grounded in common with the MS.
Second, how is your MS grounded?
Third, this isn't a spark output or ignition secondary problem. Ignore that business.
Frack the OEM grounds. Run a new ground system direct from the DB-37 to the head. Heavy stuff, like a pair of 12 or 14GA wires. Use this as your primary MS ground, and ground the LC1 through it. Make sure all the ground pins on the DB-37 (1-2, and 7-19) are commoned together at the back of the DB-37. Lay a piece of solid wire across all the pins, solder to each. Connect the heavy ground wires to this bus.
The thing you got "taken care of", was that the CAS?

No, just disabling overrun fuel cut

Still not working, added more grounds, and in the process found out that the ground on the CAS was weak (snapped it off). Anyway, I tried to get it reattached but the problem is now WAY worse.
The TPS still isn't working, but I noticed that I only have two of the three wires for it hooked up. It is well grounded, and the signal wire goes to the MS, but the third wire (which I presume is power) is hanging at the moment, and I don't think I ever had it hooked up to anything and it used to work fine.
Finally, the car has to make a 6hr drive back to Orlando at the end of the week, so if anyone has a spare CAS, I desperately need it. PM me, or call at 850-819-8092.
