MS3 Basic Tomfoolery
Enclosed is a log of MS3 basic shennanigans. I'm completely at a loss as to what is going on - the CLT is where I went "Mind. Blown. I need help."

I don't know what kind of (if any) proprietary features your MS3 has, but I would first ensure that there's not something goofy in the coolant temp sensor calibration. Recalibrate it (under the "tools" menu). Go from there.

Does that include the rpm stuff when I try to start it, Rev?
The sensor is brand new FWIW.
This is for a '94 engine to a '05 VVT swap - I'm not certain I did some parts of the wiring correctly, although I did follow Sav's instructions on the topic of the swap. The log is of several attempts to start the vehicle.
One thing that confuses the hell out of me is while I'm cranking, I can see the tuner studio rpm start at 400ish, then bounce to 100ish rpms up and down, then go to 0, then go back up to 400rpm and rinse repeat cycle while I'm cranking.

I agree with you there, Braineack.
Problem is, however, I'm unsure of where to start - I've followed Sav's instructions on the swap pretty closely, and I've hooked up the bare minimum just to get the car started at this point.
Does anyone have any advice on where to start? I'm at a loss at this point.

Disconnect everything except your timing input. Check with logger and see of that's OK.
Timing and MAP are the most important inputs to get the engine running. Everything else can wait.

Enclosed are logs with only the crank MAP and the water temp sensor connected, the cam MAP and water temp sensor connected, and cam/crank/temp/MAP connected.
Also enclosed is the msq. Any advice?
What could be causing the crank/cam signal to give a false rpm signal? I'm trying to think of what it could be, but I'm at a loss - researching over the past week has given me nil for potential causes.
Even if I fucked up the wiring on the sensors, it shouldn't be doing this.

As I think about it, could it be a bad sensor? The crank and cam sensors are brand new, but..
Or perhaps it's a setting in the msq? I'm at a loss for what else it can be now.

Why do you say it's a false RPM signal? It looks like an actual rpm during cranking in the log.
Looks like you are getting good signals from crank and cam.
The weirdest thing I see is your MAP signal right now. Are you using the onboard MAP or an external one?
Without the TPS connected, your coolant temperature seems to indicate correctly. Looking at the NoTPS log, the engine should run, assuming that the MAP is somewhat accurate. Does it fire up?

Got any suggestions Brainy?
I'm kind of at a loss, short of something going wrong with the fuel pump install. I am going to check the fuel pump and fuel pressure later today, but I'm at a loss for how to diagnose this.

There's fuel pressure, and the fuel pump works.
However, I am getting no spark. I do not know if the injectors are even firing.
I tested the cam and crank sensors for proper wiring, they appear to be correctly wired and a multimeter checks out the expected values.
Is it something in my .msq that is screwing things up?
